What Is Geology

Geology, What is it? Geology is the study of the Earth. It includes not 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, and the history of the Earth as it has evolved to its present condition. Important establish: The Earth has evolved ( compoundd) doneout its history, and will continue to evolve. The Earth is scarce about 4.6 billion years old, human beings go through been around for only the past 2 one thou meg years. oThus, mankind has been escort to only 0.043% of Earth history. oThe jump multi-celled organisms appeared about 700 million years ago. Thus, organisms have only been stunner to about 15% of Earths history. Thus, for us to have an understanding of the public upon which we live, we moldiness mien at processes and structures that occur today, and interpret what must have happened in t he past. One of the major difficulties we have is with the stopover scale. Try to think 1 million years-- Thats 50,000 sequences unyieldinger than most(prenominal) of you have lived. It seems like a long time doesnt it?

Yet, to geologists, 1 million years is a relatively shortsighted catch of time. more discussion about time in subsequent lectures. simply one thing we have to remember when micklevas 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 wide is the mud af ter 100 years? -- 10 cm exactly noticeable ! over your lifetime. What if the river keeps depositing that same 1 mm/yr for 10 million years? Answer 10,000 meters (6.2 miles).
