Question

How do geological phenomena help us to know about the history of humankind?

Answer 1

The geological phenomenon of separating various continents and water bodies from one compact landmass tells us about the age of existence of human race on the earth. Six hundred and fifty million years ago, no human race existed on the earth because the environment was not favorable. After the time when the dinosaurs were wiped out, the Mammals started existing and after the separation of landmass, the human race started flourishing on the earth.
