What drives convection cycles in the asthenosphere?

Question

a.Energy from Earth's interior.
b.Energy from Earth's oceans.
c.Energy from Earth's crust.
d.Energy from Earth's atmosphere.

Answer 1

The correct answer is: a. Energy from Earth's interior.

Convection cycles in the asthenosphere are primarily driven by heat from the Earth's interior, which causes the material in the mantle to move in a convective manner. This process is a key driver of plate tectonics and geological activity on the Earth's surface.
