Question

Which best describes the convection currents in Earth’s mantle?

They transfer potential energy away from Earth’s core toward its crust.
They transfer thermal energy away from Earth’s core toward its crust.
They transfer chemical and thermal energy in a circular pattern.
They transfer chemical and potential energy in a circular pattern.

Answer 1

They transfer thermal energy away from Earth’s core toward its crust.

Convection in the mantle involves hot material rising and cooler material sinking, moving heat from the deep interior toward the surface.
