Sedimentary rocks are naturally occurring rocks with significant physical and chemical properties. They are of three types, namely clastic, chemical and organic. While clastic sedimentary rocks form as a result of consolidation of minerals or rock fragments, chemical sedimentary rocks form through the precipitation of minerals from solutions . On the other hand, organic sedimentary rocks form as a result of compression of plant and animal remains. Sedimentary rocks form near the surface of the earth and depend on the environment of their deposition and transporting agents. Some of the common examples of sedimentary rocks are limestone, conglomerate, sandstone, coal, ...

The Effects of Climate Change on Allergies and Asthma Cases

Since the discovery of global warming or climate change, scientists have been warning the public of the possible implications this phenomenon could bring. They highlight erratic and severe weather patterns, changing ecosystems and the persistence of diseases that cannot easily be treated. While skeptics remain ignorant over these warnings and governments trying to make amends over their national policies, statistics show that these warnings should be taken seriously especially with regards to respiratory diseases such as asthma and allergies. However, it is a question as to what impacts climate change has towards the prevalence on allergies and asthma cases ...

Modern astronomy

There were four main contributors to modern astronomy: Sir Isaac Newton, Johannes Kepler, Galileo Galilei, and Tycho Brahe. Brahe advocated for the new standards for having a more precise observation even though he did not personally believe in the view of heliocentric. All of his contributions were huge for astronomy because he was able to create new instruments along with being able to calibrate them. He would check the accuracy of his instruments on a regular basis so it helped him to revolutionize instruments for astronomy. Kepler was an assistant for Brahe until he died in 1601. This helped ...

LITERATURE REVIEW: WATER TREATMENT

1.0 Literature Review: Water Treatment. 1.1 Water Quality: Water quality is the measure of water condition in relation to the requirements of various biotic species, the environment, and/or any human needs and purposes. Water quality is determined by measuring and analyzing it chemical, biological, physical and radiological characteristics. Both natural and human activities influence water quality. Natural influences that affect water quality are mainly climatic, geological and hydrological since they affect both the quality and quantity of water available (Diersing 2009). The highest influence on water quality occurs when its quantity is low, yet the limited resource must be ...

Natural Hazards: Droughts

Drought is a period recorded with less rainfall for a specific region compared to its past rainfall data, which might affect surface water flow, groundwater reserve, crop production and food availability. Impacts of a dry spell vary based on its duration as well as local people’s demand for food and water (National Drought Mitigation Center [NDMC], 2016). If the proportion of vulnerable population exposed to drought conditions were higher, then the impact of drought would also be high even if it lasted only for a short duration. In spite of being a natural hazard, the risk of its ...

Victim facilitation, victim precipitation, and victim provocation are terms used to describe the impact a victim has on a situation which labels him/her as a victim. Victim facilitation describes a situation where the negligent behavior of the victim makes it easier for the offender to commit a crime. The victim is partly to blame for a crime in a situation of victim facilitation. For instance; if a person leaves his house unlocked while he is away this may be classified as an instance of victim facilitation. Victim precipitation and provocation have a similar definition. In situations where the victim ...

In the semi-arid south-west of the United States of America (U.S.), there exist rare and lush wetlands that form habitat to majority of the US’s desert most spectacular biota. Basic biological concepts confirm that where there is permanency of adequate water at the surface or even a few feet below the ground, numerous diverse water dependent floral communities can develop. In this part of the US, there is the Sonoran Desert Ecosystem. The ecosystem is one of the few rarest and most exquisite habitation in the continental North America since majority of the original riparian habitats has long dried ...

There is a relationship between volcanic eruption and the climate of a place. After the eruption, the poisonous sulphur dioxide which is emitted out as a volcanic product, reacts and get oxidized to form sulphate aerosols in the stratosphere, hence affecting the climate adversely (Forster 2007). Volcanic ashes and particles having diameter larger than 2 um also affects the atmosphere. According to Ramaswamy (1996), ozone depletion results when the volcanic aerosols react with the balanced chemistry in the stratosphere. Mid and high latitudes volcanic eruptions create drastic climatic changes. The aerosols here retain over the hemisphere and cause climate to change. For ...

Q1) Distinguish between each of the following:

- Ecologist and environmentalist (give a Canadian example of each): An ecologist is a person who studies the complex relationships between living organisms and their surroundings. These surroundings can be living like human beings, plants, animals, etc. or non-living like the climate. They are concerned about maintaining the integrity of ecosystems as a whole. Ecology is a very vast field and covers areas like food chains, biomes, etc. Pierre Dansereau is a well-known Canadian ecologist. Environmentalists, on the other hand, are concerned with protecting the environment from harmful human actions. David Suzuki is a famous Canadian environmentalist.

The main purpose of this research paper is to discuss whether there is any proof and evidence of global climate change, as the debates about this question have been conducted until nowadays. First, it should be mentioned here that any climate change is a long-lasting considerable change in any statistical form of weather pattern`s distribution for different time periods that can vary from years and decades to thousands and millions of years. For example, it can be a change in weather conditions, or distribution of them per average conditions. It`s usually caused by different factors of biotic origin like ...

Just as James Lovelock once said, “We live at a time when emotions and feelings count more than truth, and there is a vast ignorance of science”, it is true that in this age it is increasingly important to listen to the scientific facts, as science is the best tool we have to discern whether or not climate change is caused by mankind. The term “anthropogenic” is used to describe human-made climate change and means originating in human activity. Climate change is defined in the change in global climatic patterns since the mid-20th century and is not limited to ...

Global warming is a condition whereby there is continued abnormal rise in the average temperatures, in the atmosphere. The main cause of global warming is due to the increase of the concentration in greenhouse gases, in the atmosphere (Haldar, 2011).

Greenhouse gases mainly include carbon and its compounds like methane, carbon dioxide and also the emissions coming from fossil fuels during combustion, deforestation that is major carbon sink globally also contributes to greenhouse gases increase (Haldar, 2011). Fossil fuels especially used in vehicles and industries also contribute to global warming in a major way and are as a result of human activities. ...

Abstract

The method of Enhanced Geothermal Systems (EGS) focus on the exploitation from the heat contained in deep warm rocks associated with restricted penetrability. Although that particular extraction is just feasible when the reservoir penetrability is actually sufficient to make sure a liquid circulation in between injection as well as production water springs. Financial utilization associated with enhanced geothermal systems has to do with normal or even induced nutrient precipitation as well as associated reduction in permeability from those methods even though it might inhibit liquid flow within well casings or even in rocky fractures as well as therefore decrease heat ...

A natural disaster occurs as the effect of natural hazard. The UN office for co-ordination of humanitarian affairs, defines natural disaster as the “consequences of events triggered by natural hazards that overwhelm local response capacity and seriously affect the social and economic development of a region.”. According to the UN office definition, not all natural phenomenons that occur on planet earth can be termed as natural disasters. A natural phenomenon becomes natural disaster when it proves uncontrollable during its occurrence. For instance, when hurricanes strike an uninhabited island, such a phenomenon cannot be termed as a natural disaster. In this case, ...

Global warming is a problem that is actively discussed nowadays. Very often new hypotheses appear about its impact on the Earth and human beings. At first, we need to classify the information available, to create a clear understanding of global warming effect on our planet. Global warming is the increase in the medium annual temperature of the Earth's atmosphere and oceans, because of much variety of reasons (increasing the concentration of gases in the Earth's atmosphere, solar variability or volcanic activity, etc.) (Haugen 14). Sometimes we use definition "greenhouse effect", but there is some differences between this two concepts. Greenhouse ...

Q.1 The condensation occurs due to change in temperature that causes the air to lose the ability to hold water vapor. Resultantly, the water liquefies, and appears as moisture around the bottle or cane filled with some sort of liquid. In July, the area of Tucson experiences difference in air temperature and the warmth dies out as air rises to higher altitudes with the passage of time, so the gaseous form of water takes the shape of liquid because the atmosphere lacks the power to hold the water vapor. Q.2 The air that is present at ...

Among the various issues faced by societies globally is the danger associated with the so-called global warming or climate change. Although often used interchangeably, global warming and climate change are two different scenarios that have synergistic relationship. Defined as the overall increase in the global temperature due to excessive accumulation of carbon dioxide in the atmosphere, global warming differs from climate change which is defined as the abnormally drastic change in climate patterns which have started since the beginning of the 20th century. Despite their differences, global warming and climate change are often seen as two inseparable phenomena. The ...

Introduction

Water degradation is the contamination of water (inland water that’s not saline) with materials or substances that result in the water being unfit for human, plant or animal use. Pollution may occur from chemicals, fecal waste, pesticides, sediments, petroleum or heated substances. Water sources that have been polluted are unfit for fishing, swimming, and the water is unfit for human consumption. Water quality degradation is, as a result, diffuse contaminants at the source with the spatial as well as the temporal variability that’s associated with the sources (Intergovernmental Panel on Climatic Change, 2007). It is more difficult to ...

I recently watched a documentary where scientists claimed they could create rain in the desert. I was skeptical at first. In my conception, it was not possible for man to make rain. I am very skeptical about the traditional folk tales in traditional communities that narrate of leaders who had the power to make rain. The scientists in today’s contemporary society stand a better chance of making compared to the traditional rainmakers. Even then, I reserved my skepticism about the possibility of artificially manipulating the clouds in order to create rain. It is after watching the entire documentary that I ...

It is possible to say that without complete considering of the cause of crime and deviance there is no discussion of crime and of the criminal justice. Criminologists seek for answers to the basic questions about what causes crime: Why do criminals commit crime? What are the roots that cause aggression and violence? Is it possible to say that people are genuinely good or they only motivated by self-interest? There are plenty of explanations for crime, like individual psychological differences, genetic abnormalities, some social or mental issues that might cause people to commit crime. In like manner, it is ...

Acid rains have been in the mid of attentions since the Rio Earth Summit. This is an example where anthropogenic impact combines with the nature forces. “Acid rain” is a broad term referring to a mixture of wet and dry deposition (deposited material) from the atmosphere containing higher than normal amounts of nitric and sulfuric acids” (What is Acid Rain?). Originating from the large number of causes acid rain “is created when sulfur dioxide and nitrogen oxides are discharged from industrial plants that burn fossil fuels like coal, oil, and natural gas. These compounds react with water, oxygen, and other atmospheric ...

UN POSITION ON NUCLEAR WEAPONS

There are more than two dozen countries of the world that have nuclear power, however, only a few have nuclear weapons and few are suspected of making nuclear weapons. During the cold war era between US and USSR, nuclear arms race was the most alarming feature as both the super powers rapidly built up their stockpiles of nuclear weapons. Later when both realized, there would be devastation caused by nuclear weapons, they embarked upon a number of agreements for reduction in the number of nuclear weapons. Efforts were speeded up after disintegration of the USSR; however, the issues remained a major challenge ...

Mountain pine beetle (MPB) (Dendroctonus ponderosae Hopkins) is a bark beetle that lays eggs within the vascular system of the mature trees of lodgepole pine (Pinus contorta). First known epidemic infestation was recorded in 1994 in the forests of British Columbia (BC). Prior to 1994, the infestation was negligible, owing to the fact that extreme low temperatures of winter killed the beetle, thereby curbing the problem. In the past two decades, however, due to global warming the winter temperatures are not low enough to kill the beetle. This has escalated the problem of deforestation and thereby has unbalanced the ...

Objective

Purpose of this laboratory is to inspect the effect of precipitation hardening in Aluminum and steel alloys. Theory Hardness is a property of a material which delineates resistance to permanent or plastic deformation. For metals, hardness is generally defined as the resistance to indentation. One way to attain hardness is to look into the effect of precipitation hardening. This type of hardening helps to detain the yield strength in the material. There are four methods used to test hardness of a material: Rockwell, Brinell, Vickers, and Knoop. The Rockwell hardness test measures the depth of indentation, while the other three ...

ABSTRACT

Spring-time events such as flowers budding have advanced by two and a half days per decade since the 1970s in Prairie regions (Korner C, Science, 2010).The flowering of a plant is a central event in its life-cycle, especially in plants growing in temperate regions of the world. These events are known as phenological changes and phenology is the study of plant and animal life-cycles in relation to annual and seasonal climate variations. Flowering phenology combines various diverse fields of study such as plant physiology, climatology, historical studies, and botany (Tooke F, J of Exp. Biology, 2010). The break of dormancy ...

The development of Russia had many historical turning points. These changes were mainly connected with such political figures as Lenin, Stalin, Khrushchev, Brezhnev, Gorbachev, Yeltsin, and Putin. The Soviet economy depended on mostly political decisions but not economic programs. Although the basic economic system in Stalin, Khrushchev, Brezhnev eras remained unchanged, there were some peculiarities in these periods. The effect of Stalin’s policy had a profound impact on people and the state. In 1928, the Communists instituted the first Five-Year Plan. It dealt with such aspects of development as an industry, consumer goods, agriculture, transportation, communications, health, education, and ...

According to the University of Rhode Island (URI, 2014), time series graphs compare the variable under observation on the vertical (Y) axis against time on the horizontal (X) axis. Cycles reveal the trend of the collected data over time through plotting points on the graph which in turn produces the highs (peaks) and lows (troughs). The cycles reveal the variations in performance. When a scientist plots two lines (waveforms) on the same graph, the two waveforms provide a graphical comparison of performance between two subjects under observation. 1) When peaks and troughs align, does this mean the data is more ...

Causation of Climate Change

The world’s climate system is composed of five elements that include hydrosphere, lithosphere, atmosphere, cry sphere, and biosphere. It varies naturally with time and is dependent on the incoming and outgoing energy which determine the optimal balance of the earth’s energy. These determinants constitute factors that cause climate variation that result in either warmer or colder states. This result into a phenomenon referred to as climate change. This is a condition, in which, the earth experiences adjustments in its weather that occurs over a period. This essay provides a detailed analysis of the causes, characteristics, and the impacts of climate change ...

Introduction

Global warming refers to the gradual rise in the total temperature of the atmosphere of the earth. The rise in temperature is attributed to the effects of the greenhouse gases, which is caused by an increase in the levels of chlorofluorocarbons, carbon (IV) oxide and other pollutants. Global warming affects the climate system of the earth’s atmosphere by increasing both the terrestrial radiation and the radiation from the sun. The ozone is an essential element in the issue of global warming. The ozone absorbs the heat radiated from the sun and the surface of the earth, leading ...

Gravimetric analysis

Introduction Gravimetric analysis is a method of measuring of mass of chemical substances. This analysis can be classified in two types; precipitation and volatilization (Bassett et al.). In precipitation method some steps, involved to determine quantify of the chemical substances, are separation of an ion in aqueous solution by a reaction, filtering and washing the precipitate, converting the precipitate to a substance of known composition, and lastlytaking weight of the precipitate as well asevaluating its mass. The chemical substance must be precipitated fully.Theunknown amount of original ion can be evaluated from the mass and known composition of the precipitate. Gravimetric method ...

Eastern Saudi Arabia and Indiana State have significant geographical differences; hence the climate differences are evident. Excluding the western region, Saudi Arabia is mainly characterized by a desert climate (Zereini and Heinz 77). During the day, the country experiences high temperatures during the day and unexpected drop of the same during the night. Taking into consideration that it is a desert country, Saudi Arabia records minimal amount of rainfall annually. In fact, rainfall is most experienced in the Western Coast, and mainly between October and March, during which an average of about 300 millimeters are recorded (Zereini and Heinz 79). During ...
