Question

Quizplus · Accepted Answer

External processes near Earth's surface are primarily powered by the energy that is received from the Sun. The Sun provides heat and light energy that drives processes such as weather, erosion, and plant growth. While geothermal heat from Earth's interior can also contribute to surface processes, it is not the primary source of energy for external processes. Radioactive elements in Earth's mantle and cosmic rays also have little direct impact on processes at or near Earth's surface.
