Sea-Floor Spreading
Copy the following map of the ocean floor between continents.
Label the parts of your map as we go along.

Sea-Floor Spreading
Mantle
Oceanic crust
Mid-ocean ridge
Convection currents in the asthenosphere push the crust apart.

Sea-floor spreading
Mid-ocean ridge
Sea-floor spreading:
New magma is pushed up at the mid-ocean ridge, which pushes the older
rock away.

Subduction: Old oceanic
crust is pushed under a continent causing the rock to melt back into
magma in the mantle.
