    It’s the Geosphere…it’s the portion of the Earth system that includes the Earth’s interior, rocks and minerals – including oil.

    It is rotting matter (trees and peat and dead dinosaurs), trapped in rock formations, deep in the crust of the earth.
    Before man none of that was ever taken away and the topsoil was never as exposed as now…
