The mantle of Earth is made partly of magma. When magma rises and sinks, this is called ______________.

• a conduction current

• a hot spot

• a volcanic eruption

• a convection current

When the force of subduction and gravity moves a lithospheric plate downward into a trench and pulls it away from a ridge.

• Sea Floor Spreading

• Subduction

• Ridge Push

• Slab Pull

These develop in the mantle moving the crust and outermost part of the mantle and transferring thermal energy from Earth’s interior to its exterior.

• Epochs

• Convection currents

• Paleomagnetism

• Magnetometer
