earths geological history essays

earths geological history essays Scientist would need a variety of different pieces of evidence to document the scope and scale of geologic history. The earth is billions of years old, therefore rocks are obvious evidence of it's geologic history. Since all natural land masses ever created on earth stay on earth, it is a fact that the scope and scale can be determined by using it as evidence. The movement of the land masses and land creations can help determine the scope and scale of earth's geologic history. Rocks are obvious evidence of geologic history. Rocks come from the interior of the earth. They are created from magma, and change its form over years of weathering. Scientist also use rock layering as evidence for the Earth's age. The earth's crust has many different layers which represent many different time periods. The amount of years are shown in a time period. Rocks change over time, and that is absolutely what evidence scientist need to document the scope and scale of geologic history. The movement and creation of large land masses are suitable evidence for a scientist to help document the scope and scale of earths geologic history. Over time the large land masses move and change shape and Scientist are able to estimate the years of changes. It took billions of years to separate "Pangea" into separate continents. Along with the movement of the large land masses fossils, bones, and rocks are buried underground. Since the continents were once connected, there was massive earth movements which separated the large land mass known as Pangea. Mountains, rivers, and seas were created and are evidence that can be used . Scientist would need a variety of different pieces of evidence to document the scope and scale of geologic history. Rocks, movement of large land masses and land creations are evidence scientist can use to document the scope and scale of earths geologic history. Everything ever created naturally on earth stays on earth, t...
