Summary
Introduction Theoretically, the earth was formed about 4.6 million years ago when the sun was formed. In its initial formation stage, the earth was a ball of molten magma that revolved violently around the newly formed star, the sun, and it collided with many other smaller rocks and debris from other planets in the solar system…

Download file to see previous pages The earth has undergone very many physical changes on its geological features since its formation. The earth’s continents have been drifting apart for millions of years since their formation. 760 million years ago, during the initial stages of drifting, the earth’s continents had combined to form the Rodinia super continent. Around 600 million years ago, after rodinia broke apart, the continents drifted and formed Pannotia. Pannotia broke apart and the continents later formed Pangaea. Pangaea broke apart and the continents started drifting away from each other, 180 million years ago. The history of the geology of the earth is divided into chronological eras during which the earth had some outstanding characteristics and major geological events took place. This paper addresses the history of the geology of the earth. The Precambrian eon The Precambrian is the era began at the time of the formation of the earth and lasted till around 570 years ago. This period of time makes up to about 90% of the earth’s geology history. In the initial period of the Precambrian, the earth was cooling down and it formed a crust that made its surface. The rocks that were formed were mainly volcanic and igneous intrusions rocks which were spread all over the surface of the crust. The Precambrian had three long eras, the hadean, Archean and the Proterozoic. The Hadean lasted almost 700 million years after the earth’s formation. During this period, the earth cooled down and there was the formation of the earth’s surface which was mainly composed of volcanic belts. The temperature of the earth’s surface was still very hot but it was gradually cooling down due to the reduction in collisions with huge rocks in the earth’s orbit. It is also during this period that the earth’s moon was formed. Archean is the era that followed. It lasted from 3900 to 2500 million years ago. The earth experienced tectonic processes that formed sedimentary basins on its surface (Stanley 55). The rocks dated from this period reveal that there was simple life; bacteria and algae fossils were present on the rocks. The proterozoic period, 2500 to 570 million years ago, was characterized by the formation of vast rifts on the earth’s crust. The rifts were filled with volcanic rocks as well as the sedimentary rocks from the sedimentary basins (Sasso 59). This period also saw the formation of seas in which a lot of iron minerals were formed. There was early life in the seas and the amounts of oxygen kept increasing in the atmosphere. In the proterozoic eon, the Rodinia super continent drifted apart and later the Pannotia super continent was formed. Glaciers also started forming on the earth’s surface in the eon. The Phanerozoic Eon This is the eon in which the earth is currently in. It wraps the geology history of the earth from 550 years ago to date. After the breaking of the Pannotia super continent, the continents drifted and recombined to for the Pangaea. Pangaea then broke into the current continents. The continents have been constantly drifting apart. The phanerozoic eon is also categorized into three eras, the Paleozoic, Mesozoic and the current Cenozoic eras. All these eras experienced significant geological changes of the earth (Zhao, Sun,Wilde & Li 94). The Paleozoic Era The Paleozoic era, 570 to 245 million years ago, marked the end of the ice age and the beginning of early life on earth in the seas. It ...Download file to see next pagesRead More

...? Energy Saving Bulbs Introduction The concept of reducing unnecessary energy wastage, and decreasing levels of carbon footprints of each individual,home, and organisation, is slowly gaining a strong foothold amongst the mindset of the general people. One of the easiest and the least expensive means to instil energy efficiency within the homes of the common man is to use energy-saving bulbs, instead of the traditional incandescent light bulbs. In this article I will examine the energy saving bulbs, while comparing it with the traditional ones; and study as to how these power saving lamps work. Discussion Traditional lamps are known to be energy guzzlers, and have either been banned in many countries, or are being slowly phased out...

How many existed in the Eocene? Explain and list. According to Harris et al. there are currently approximately 7,000 islands and islets in the Caribbean however during the mid-Eocene era the region had assumed its modern geographic configuration. From this perspective it remains the cast that although there are several thousand islands and islets many of these become submerged during high tides. The major islands and...

...enormous distances, so there are no major genetic differences between these populations. The distribution of polar bears in their habitat is far from even and is highly dependent on the availability of their prey. In the central areas of the polar icecap there is only very limited access to prey, and the density of polar bear populations is thus considerably lower there than in the productive areas in the bordering zones. Concepts and Values of Biodiversity The term biological diversity', often shortened to biodiversity', is an umbrella term used to describe the number, variety and variability of living organisms in a given assemblage. Biodiversity therefore embraces the whole of Life on Earth'. Decline in biodiversity...

...Geology Earth itself has had its share of unfathomable mysteries and the universe with all the heavenly bodies occupying it appears vast in mystery and beauty. For one, the exhibition via the Cullman Hall of the Universe is particularly striking. Viewers like me are chiefly left with an impression that universe indeed is ever-expanding. At that moment, I was brought to ponder about the size of God who is behind such an incredible idea which reflects the great astrophysical value of matters in the outer space. During this stage, the sight of the exhibits drew me to the interest of imagining how quantum particles could have possibly been of the evolution process of the cosmic materials comprising the...

Introduction The world may compose only of one-fourth land from its total composition, but it brings out thousands of captivating sceneries and landforms when, apparently, almost each country and every continent has something to brag about. Primarily, land formations around the world are caused by the theory of tectonic plates--the motion of the surfaces of Earth against its igneous core (News Staff, 2008). All land formations were believed to have surfaced because form this very idea. The focus of this paper is to identify landforms found in the Southern California. 2.0.

...The history and arguments about the origin of the earth and evolution have given many scientists sleepless nights trying to unearth what might have actually happened long before we came into being. Scientist hope that one day the matter will be put to rest by providing evidence and be able to prove to the world beyond any reasonable doubt that certain specific activities took place. Their progress is mainly centered on the rocks which are the source of their evidence. The discovery of rocks which will provide the evidence and chronological evidence was a great milestone.

Calcite, Marcasite and Galena

... CALCITE AND MARCASITE ON GALENA. Calcite is a mineral that is formedfrom the reaction of calcium and carbon to form(CaCo3), and occurs in granular or compact shapes, exhibiting a white color in pure form or grey, blue ,black, red ,yellow or orange if it has some impurities. Due to its carbon nature, it can easily be reacted or dissolved with most acids or water to release a carbon dioxide gas Its retrograde solution thus fairly soluble in hot water and subject to the favorable conditions of precipitations will give a cementing product to the apparent rock and a porosity on dissolution and its removal from the rock on dissolution. The calcites are usually transparent or opaque and have traces of phosphorescence... CALCITE AND MARCASITE ON ...
