Question

Why there need to study earths layer

Answer 1

Information saved in rocks and minerals recounts the staggering story of the Earth's 4.6 billion year history. Contemplating fossils and the stones in which they are discovered gives us knowledge into how life has broadened from its unassuming beginnings as single cell microbes to the heap of life structures we see today. Considering the stone record gives us knowledge into past ecological changes, from which we may have the capacity to make forecasts about how the Earth could change later on.
