Answer 11

radioactive decay
friction
heat from earths core

Question 12

driving force for plate tectonic movement

Answer 12

Mantle is a liquid
Temp becomes warmer as you go deeper
Mantle rock near core heats up and rises. As the rock rises, it cools; cool mantle sinks
Convection currents within the mantle drive the plate movement. density
