• heat in the Earth's core

• convection currents

• conveyor belts

The uplifting and tearing apart of lithospere occurs at

• transform fault boundary

• convergent boundary

• divergent boundary

• mantle

Arrange the following events in the mantle convection process.

a. Heat moves from the core.

b. The process repeats as a cycle.

c. Heat slowly rises to the mantle and creates convection current.

d. The decomposition of radioactive elements causes heat in the interior of the Erath.

e. Lithospheric plates move in the asthenosphere due to the rising and sinking of materials.
