The solar radiation energy reaching the earth is only a small part of the total solar radiation energy, but its effect is quite large. Solar radiation [4] is the main source of energy on the earth's surface.
First, the impact on the geographical environment. Direct effects such as the weathering of rocks due to temperature changes. Indirectly, the atmosphere, water, and living things on the earth are the elements of the geographical environment. The development and changes of themselves and the interrelationships among the various elements are mostly done during the driving process of the sun.
The surface of the earth is divided into five zones. Why divide the five bands? Because the latitudes of different places on the earth's surface are different, the solar heat obtained in different latitudes is different. For example, in a tropical year, the sun can shoot directly and get the most heat; the sun in the cold zone is very low, and there is a long polar night, so the heat is the least.
That is to say, because the solar radiation has latitude differences, there is a difference in the amount of heat obtained from different places. However, in places where the heat is surplus, such as the equator, the temperature is not getting higher and higher; in places where the heat is deficient, such as the poles, the temperature is not getting lower and lower, but it remains relatively stable. For the entire surface, the heat should be balanced, so heat transfer occurs where there is excess heat and insufficient heat.
Second, solar radiation provides energy for our production and life. People's most direct perception of the role of solar radiation comes from it being the main energy source for people's production and life.
