The Earth and the Organisms in It

The earth is very senior. According to the geologists, the earth is 3.5 billion old age old. They based this by the fossils that they discovered. The organisms were fossilized and were stored in stones, then they swing protrude experiments like carbon dating to determine how old is that fossil. Most of the fossils be found in mountains. Several geologists atomic number 18 studying mountains and rocks. In Australia, at that place are rock formations that are found to have existed and formed millions of years ago. This rock formations were considered to be the archives of the earths history. They found out that there are certain part of these rocks that contains crusade deposits. According to the geologists, the iron that were deposited in the rocks were originally from the inside of the earth that were released during volcanic activites. Before, the irrigate is type O poor so the iron released during volcanic action is dissolved in water but as the oxygen increases, the iron is becoming insoluble. As a result, the iron is deing deposited in the land,soil, and rocks instead in amniotic fluid. At the beginning, the earth was not able for sustaining life but as the years passed several processses do the earth suitable for the presence of life. These processes that shaped the earth gave itinerary to the development of different species.

When the earth was still poor of oxygen, the species of plants that brandish during that time were seted to low oxygen environment. According to the geologists and scientists, the plants which produces oxygen started vivacious in waters and in conclusion learned to adapt to the land. The earth experienced ice age, in which all the waters were frozen. They say that the freezing started in the south pole and eventually spread throughout the earth. During the ice age, many species of living organisms were wiped out and was not able to survive the harsh environment. Most of the living organisms that were able to survive were the burrowing organisms, organisms that were well adapted... If you want to get a full essay, order it on our website: Orderessay
