Answer 1

Convection cycles in the asthenosphere are primarily driven by energy from Earth's interior. This heating comes from various sources, including the decay of radioactive isotopes, residual heat from the planet's formation, and heat produced by ongoing geological processes. As the hotter, less dense material in the asthenosphere rises, it creates convection currents that can lead to tectonic plate movement.
