Dynamic Earth
The earth did not always look what it does now.
Pangaea was a large landmass that united the
continents around 250 million years ago. The
continents separated and shifted over time.
Continental drift is the name for this process.
,Structure of Earth
, Convection Currents
The earth's plates float on semi-molten magma in the mantle.
It is the movement of the magma that causes plates to collide, separate or
slide past each other.
magma moves in circular motions called convection currents.
