Question

EXPLAIN what is happening below the Earth’s surface that is causing the lithosphere to shape our crust in this way.

Thanks for helping

Hi there!

Underneath the Earth's crust lies the mantle which is a thick layer of molten rock. This rock moves in convection currents (up and down with the hot rising and the cold sinking in a long cycle) which in turn moves the lithosphere and allows the tectonic plates to glide across generating volcanoes, mountains, trenches, etc.
