Essays on Basalt

Hawai'i was the 50th state to join the USA. It comprises 132 islands and is said to be the home of volcanic islands. These islands reside in the Central Pacific Ocean. Moana Loa is one of the top most active volcanoes that had formed the island of Hawaii in the ocean (Networks, 2016). The movement of plate tectonics has resulted in the volcanic eruption and, however, the volcano towering and presence of valleys had a significant impact on the economic value.

Theory of plate tectonics

Plate tectonics theory explains that upper layer of the earth’s surface is segregated into various plates that ...

Object 1: Medium: Wood and abalone Current location: Provincial Museum of British Columbia Image sourced from: Historica Canada . (2015, March 4th). Indigenous Art in Canada: Frontlet. Retrieved July 7th, 2016, from Historica Canada : http://www.thecanadianencyclopedia.ca/en/article/aboriginal-art-in-canada/ A product of the Tsimshan culture, this Frontlet features as one of many examples of North American aboriginal artistry. The frontlet has been suggested as one of the most noted art forms of the Iroquois civilization that occupied large swathes of Canada. The Iroquois created various abstractions of these Frontlets, also known as False Faces, and they were typically created to feature as sacred ...

All Sciences, whether Physical, Social, or a combination of the two (like Anthropology), are based on hypotheses and theories. Some of the unlikeliest scientific theories have arisen from hypotheses that were considered insane at one point. In the world of Anthropology, the situation is no different. At one point, any supposition that the earth had been formed over billions of years rather than created in a biblical manner was considered criminal. Governments were so thrown apart by statements like this that people were decried as heretics, beheaded or sent into exile. These scientists went against what was mainstream thinking ...

The continental plate in the eastern part of Asia is composed of various volcanoes and tectonic movements. Most of the volcanic rocks in this region are composed of alkali basalts with signs of continental contamination. There are various models that explain the region’s magmatic evolution. The two most common models used to explain the movements refers to the surficial processes and the other one refers to the deeper processes associated with the Pacific ocean plate. These two processes are antithetic and may hay happen subsequently. The volcanism can be traced by tomographic imaging that can be directly associated ...

The continental landscape features are reflected with analogous features on the ocean basins. Plains, Plateaus, volcanic cones, rolling hills, mountains, and valleys are found underwater in the oceans just like on land. However, research reveals that the largest mountains found beneath ocean waters are higher as compared to those on the continent. Also, the plains found under water are more extensive and flatter than those on the dry land.

The Shape of the Land

The ocean basins can be referred to that surface of the Earth that extends towards the sea from the margins of the continent. Ocean basins are usually submerged in the ...

It used to be fun to visit museums when in school with friends and school groups. However, my visit to Los Angeles County Museum of Art (LACMA) was different, as now I was in college and going there not just because everyone is going, or that your school or teachers have organized a tour, but I was going there based on my own plans and decisions. I had heard a lot about LACMA and decided to get more information about the museum online. I explored the website of LACMA and learned about the history of the museum. I learned ...

Molcajete in Mexican means pestle and mortar. They are made from a block of basalt and are usually round with three legs. Three legs are meant to provide it with support as force is applied to it during grinding. Decorations are usually animal heads painted on to give it the look of a stout animal. Pigs are the most common animals used in the decorations. In the early days, they held sentimental values, but pigs on modern day molcajetes are simply used for decoration. The earliest use of the Molcajete was in a place called tehuacan, a valley of ...

"Visiting card" of Egypt is the pyramids. There are about hundreds of them - large and small, with smooth and stepped sides that have survived virtually unchanged and more look like a shapeless heap of stones. They are located along the left, West Bank of the Nile in small groups near the place, where in the era of the old Kingdom was the capital of the country - Memphis. The most famous of the pyramids are on the outskirts of Cairo, on the edge of the desert plateau of Giza, looming over the green valley of the Nile. Here ...

Concrete – one of the most common materials used in the construction of residential buildings, industrial, administrative, social, commercial buildings, etc. an important step in the construction of certain buildings is the reinforcement of concrete. Not so long ago, the reinforcement was made with metal or steel rods. However, with the advancement of technology, they were replaced by other, superior to a number of parameters and characteristics materials.

The main types of composite reinforcement

The rods made of glass, carbon, basalt or aramid fibers and those that have undergone special processing, are called non-metallic fittings. There are several varieties. The classification is based on the fiber ...

Minerals are classified by their chemical composition as Silicates, Phosphorites, carbonates, and halides are all major mineral groups.

Silicates contain silicon (Si) and oxygen (O), the two most abundant elements in the earth and comprise the majority of Earth's crust. They have a chemical formula SiO2. Common silicate minerals include olivine, pyroxene, amphibole, mica and quartz.

Phosphorites are sedimentary rocks of biochemical origin and are rich in phosphate with chemical formula PO4. They are mostly used as chemical fertilizers. They are also used as food preservatives, anti-corrosion agent and also in the field of metallurgy. Limestone and mudstone are common phosphate bearing rocks.Carbonates are the minerals mostly found in the Earth’s near surface crust. They have ...

I liked Dante’s peak because it starred two of my favorite movie personalities, and there was enough action to keep my interest. As far as the geology as portrayed in the movie, the movie makes does a very good job of ensuring that the physical geology is represented very close to the real appearance. The many, though not all respects, the depiction of the eruptive dangers of volcanoes come very close to the mark. This is especially so with regards to the massive eruptive power released during a volcanic eruption. The Cascade Range stratovolcanoes of Alaska erupt explosively and release ...

Abstract

The Lake Moeris Quarry Road built while the Old Kingdom of Egypt between 26th and 22nd centuries B.C. is the oldest paved road of the world and is testimony to the excellent sense of planning and execution of the ancient Egyptians of that period. The 8-miles of the main road was built by placing large stone blocks that were kept on the desert sand and to facilitate passage of sledges filled with blocks of Basalt to the quay of Lake Moeris, and then on to River Nile. Those Basalt blocks were shipped downstream of Nile to construction sites in ...

Volcanism refers to the eruption of magma or molten rock, or hot water and steam, including volcanoes, pyroclastic fragments, geysers, as well as fumaroles on top of the surface of a planet (Encyclopedia Britannica 1). A volcano refers to the vent through which gases and magma are discharged. When a planet loses its internal heat it results to volcanism. When a rock that is close to the surface becomes hot sufficiently enough to melt, it results to a volcano being formed. On the Earth, volcanism often occurs in association with plate boundaries. Where two plates move apart, for instance at mid-ocean volcanic ...

Mauna Loa Volcano within Hawaii largely erupt a rock type referred as basalt (HCV, 2008). When in molten state, basalt generates liquids of high fluidity. The fluidity of the molten basalt supports the flow of lava that is why the Mauna Loa Volcano generally has gentle sloping sides (HCV, 2008). The high eruption rate occurring at Mauna Loa Volcano, together with steep slopes, favors far and fast flows of lava or magma. In contrary, Mayon is categorized as a composite cone or stratovolcano. It is made of deposits formed primarily by four main forms of volcanic activity: pryoclastic flows, air-fall ...

Abstract

In this essay, it is presented a resumed description of the different volcano types that can be identified, according to the types of rock layers they leave behind after their erosion. The main types of volcanoes that can be identified are the stratovolcanoes, which leave behind layers of rock of different components, according to the eruption of pyroclastic nature, ash, water, or tephra; the shield volcanoes, that leave behind large layers of smooth basalt; the cinder, or scoria, cones that leave behind thick basaltic blocks, which can be interbedded with ash or cinder layers. Keywords: volcanoes, types, stratovolcanoes, ...

The Igneous rocks, also referred as Plutonic rocks are one of the main rock types apart from metamorphic and sedimentary. These rocks can be formed either by intrusive or extrusive process depending on the location on the earth’s surface. The cooling and crystallization of magma (melted rock) inside the ground or above the ground creates the igneous rocks. Eruption of volcanoes also causes the formation of Igneous Rocks when the magma intensifies above the surface of the earth. The magma that rises above the surface is referred as Lava and the igneous rocks form when the lava solidifies. ...
