Why does subduction occur?

• Old crust is more dense and gravity helps pull the crust back into the mantle.

• Old crust is less dense and it sinks back into the mantle.

• Old crust is warm and melts back into the mantle.

• Old crust has no where else to go but through trenches.

Convection currents happen when

• Rock/magma gets heated and sinks. It then cools down and rises.

• Rock/magma doesn't move.

• Rock/magma gets more dense and rises. It then cools down and sinks.

• Rock/magma gets heated and rises. It then cools down and sinks.
