If the solar radiation strikes the earth's surface without undergoing any of these three processes, it is referred to as direct solar radiation. The incoming energy may interact with the earth's environment in three different ways: scattering, absorption, and reflection. The earth receives solar energy in the form of shortwave radiation. The amount of heat energy received by the earth and radiated back to space is close to being balanced with the earth nearly approaching a state of radiative equilibrium. Scientific research has shown that each square meter on the earth's surface receives and gives back approximately 240 watts of energy from the sun. The earth's shape also makes it so that the polar areas receive considerably less heat than the regions closer to the equator. Due to the shape of the planet, the amount of energy that strikes the earth's surface is significantly uneven with some areas receiving substantially greater amounts of heat than others. The heat that the earth receives goes into five distinct components of the environment: living things such as plants and animals, the earth's crust, the earth's water bodies, the atmosphere, and the ice. ![]() The sun provides all the energy that is utilized within the earth although most of the sun's energy never reaches the planet's surface. ![]() The term ‘earth's energy budget’ was coined to refer to the energy the planet receives from the sun, utilized all over the earth, and then sends back into space.
