Question
What causes plate tectonics to occur?
- Thermal convection
- Thermal conduction
- Solar energy
- Erosion
Hint:
The heat stored inside the earth's crust builds up to point of extreme pressure.
The correct answer is: Thermal convection
- The heat from radioactive processes within the planet's interior causes the plates to move, sometimes toward and sometimes away from each other.
- This movement is called plate motion, or tectonic shift.
