Colder, more dense magma near the crust...

• rises.

• sinks.

What causes convection current in the Earth?

• The uneven heating on each layer inside the Earth.

• The crusts outer layer.

• The temperatures we feel outside.

Ocean currents are created by

• Dense cold water sinking

• Dense cold water rising

• Less dense water sinking

• Less dense warmer water rising and more dense cold water sinking
