earths geological 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. Rocks change over time, and that is absolutely what evidence scientist need to document the scope and scale of geologic history. Scientist also use rock layering as evidence for the Earth's age. It took billions of years to separate "Pangea" into separate continents. Mountains, rivers, and seas were created and are evidence that can be used . They are created from magma, and change its form over years of weathering. Since the continents were once connected, there was massive earth movements which separated the large land mass known as Pangea. The amount of years are shown in a time period. Over time the large land masses move and change shape and Scientist are able to estimate the years of changes. Rocks come from the interior of the earth. Everything ever created naturally on earth stays on earth, therefore it is fact that this is sufficient evidence for a scientist to use.

Scientist would need a variety of different pieces of evidence to document the scope and scale of geologic history. The earth's crust has many different layers which represent many different time periods.

Along with the movement of the large land masses fossils, bones, and rocks are buried underground.
