Past is the key to present is given by the law of uniformitarianism. Thus its important for the scientists to study the life on earth.
Explanation:
The principle of uniformitarianism is geology suggests that the same earth process that used to operate earlier is also operating presently but not with the same intensity as then.
So for studying the processes when life began on the earth its essential for scientists to have knowledge of the pat landscape which was formed by the same process like river erosion, wind erosion, glacier erosion and deposition that continue even today.
James Hutton gave this concept in 1785, presenting the fact that history can be recreated with the help of certain factors, such as weathering of bedrocks for thousands of years ago.
It should be A! Bowen's reaction series where minerals form from magma in predictable patterns! (: I hope all is well, and you pass! Good luck, rockstar! (:
The Mississippi delta is located on the northwest part of the state of Mississippi and is the most southern place on earth and is 7,000 square miles of alluvial flood plains are created by the regular flooding of the Mississippi and Yazoo rivers for thousands of years.
The river deposited sand, and clay, silt along its banks and in adjacent basins, and is shaped of a bird's foot reflecting the dominance of the river over the hydrological and processes. As the river changes its course the natural flow of freshwater and sediments change as well.
