What are the sources of energy for the processes that affect Earth?​
marissa [1.9K]

Answer: ok so Most of the energy in the Earth system comes from just a few sources: solar energy, gravity, radioactive decay, and the rotation of the Earth. Solar energy drives many surface processes such as winds, currents, the hydrologic cycle, and the overall climate system. Gravity makes rivers and other materials flow downhill and creates tides (from the Moon's gravitational pull). Radioactive decay creates heat in the Earth's interior, while Earth's rotational forces influence currents of air and water.
