What two sources of energy for processes in Earth's lithosphere hydrosphere atmosphere biosphere?

The two main sources of energy for processes in Earth's lithosphere, hydrosphere, atmosphere, and biOSphere are sunlight and heat from Earth's interior. Sunlight drives photosynthesis in plants, atmospheric circulation, and water cycle processes. Heat from Earth's interior powers geothermal activity, plate tectonics, and contributes to the internal energy of the planet.
