What Is Geology

Geology, What is it? Geology is the study of the Earth. It includes non lonesome(prenominal) the surface process which pass on shaped the domains surface, still the study of the ocean floors, and the interior of the Earth. It is not only the study of the Earth as we see it today, barely the history of the Earth as it has evolved to its present condition. Important bow: The Earth has evolved ( compoundd) doneout its history, and will continue to evolve. The Earth is undecomposed about 4.6 billion years old, human beings go through been around for only the past 2 one railyard meg years. oThus, mankind has been escort to only 0.043% of Earth history. oThe offshoot multi-celled organisms appeared about 700 million years ago. Thus, organisms have only been happen to about 15% of Earths history. Thus, for us to have an understanding of the body politic upon which we live, we moldiness mien at processes and structures that occur today, and interpret what must ha ve happened in the past. One of the major difficulties we have is with the fulfilment scale. Try to think 1 million years-- Thats 50,000 sequences extensiveer than approximately of you have lived. It seems like a long time doesnt it?

Yet, to geologists, 1 million years is a relatively short finale of time. more discussion about time in subsequently lectures. simply one thing we have to remember when studying the earth is that things that seem like they take a long time to us, may take only a short time to earth. Examples: A river deposits about 1mm of sediment ( bollocks) each year. How cryptical is the mud after 100 years? -- 10 cm exactly noticeable over your lifetime. What if the river keeps depositing that s! ame 1 mm/yr for 10 million years? Answer 10,000 meters (6.2 miles).
