Introduction

A fossil is any substance that evidences a once-living organism (University of Arizona, 2016). As such, fossils evidence the ancient life forms which inhabited the earth long time ago and were preserved by a natural process. Most of the fossils are found in sedimentary rocks formed from the sediments of rivers, seas, and lakes. Some of these fossils are actual remains of living things such as bones, or events that happened in the past, for instance, the dinosaur footprints. However, it is ordinarily the hard parts of organisms that get preserved under the right conditions and the interaction of ...

Abstract

This study aims at examining different methods used to study the composition and variation of marine organisms and plants. Various methods create different results that show the effect of the geological environment structure in the ecosystem at various oceanic conditions. Temperature variation is used as a major determinant of the population distribution of the organisms and plants found in various ecosystems. For instance, this study will use crocodilian fossils and mangroves to assess the composition of ancient oceanic environments and the trend of the climate and geological change in these conditions (Häder 1999). This study uses some isotopic ...

Visit the Virtual Caves website: http://www.goodearthgraphics.com/virtcave/index.html. Briefly describe and provide an example of Solutional caves, Sea caves, Erosional caves, and Lava tube caves. Solutional Caves: Solutional caves are formed by chemical reaction between the groundwater and the rock bedrock consisting of limestone. Ground water contains dissolved carbon dioxide which is a weak solution of carbonic acid and is capable of dissolving the rock slowly. This makes the passage of water wider and takes the shape of the cave. The most common example of solutional caves is flowstone. Flowstone is mostly composed of calcite and becomes rounder as it tends ...

Water and Its Unique Properties

Water is has a unique physical and chemical properties which are essential to life and to the earth processes such as climate change. Water molecules generally consist of one oxygen atoms and two hydrogen atoms. However the atoms do not share equal electrons thereby making water slightly charged—exhibits polarity. Water molecules interact with other water molecule through a weak hydrogen bond. Hydrogen bonds allow water to interact also with other polar substances. Water is known as the universal solvent. Thus, it has the capacity to dissolve various polar substances like ammonia and nonpolar substances such as methane (Freudenrich, 2011). ...

Introduction

Carbon dioxide is the main byproduct in a brewery. Accordingly, we have identified source of carbon dioxide, as an exhaust gas produced in a brewery. This report explains how such a source of carbon dioxide can be harnessed for future use.

Air extraction technology to capture atmospheric carbon dioxide

We understand that due to excessive burning of fossil fuels there is abundance or more than expected amounts of carbon dioxide in the atmosphere. Accordingly, carbon dioxide can be extracted from atmospheric conditions using various technologies. This technology of carbon dioxide capture is a step wise process, which is called air extraction (Zeman and Lackner, 2004). In this technology, the ambient air ...

The golden throne of Tutankhamun is believed to have been inspired by the worship of the sun disk god, Aten. From the images on the throne alone, one can already see the prominent feature of Aten at the topmost center of the seat with its rays extending toward Tutankhamun and his queen, Ankhesenamun. This is also the only portion of the seat where unbroken gold was solely used probably since a diety as great as Aten cannot be represented by any lesser metal. Looking closely, we can also observe the hands of Aten extending to the nostrils of Tut and ...

Until today, over 2000 minerals have been discovered, and constantly on a daily basis, new minerals are discovered. Minerals just like matter is made up of atoms of elements arranged in a particular way together with a definite chemical composition. Notably, minerals are aggregates of nearly all rocks found on the earth’s crust. Geologists define minerals as inorganic materials on and in the earth’s crust with a specific chemical composition. Most minerals are always naturally occurring and it is worth noting that nearly all the minerals contain crystals. This is attributed to the fact that mineral particles are usually arranged in a ...
