What is energy that is absorbed by land and water changed into?
Solar energy that reaches the surface of the Earth is primarily in the visible light spectrum and we often refer to it as short wave radiation. This is because the wavelengths are around 0.5 microns. As this energy is absorbed the Earth heats up and releases energy primarily around 10 microns in wavelength or long wave radiation. This is also referred to as infrared radiation or simply heat.
