1. Climatic zones of the Earth The amount of solar radiation decreases from the equator to the poles, and the air masses are formed depending on the geographical latitude. Therefore, each latitude is characterized by its signs of climate. In this way, according to latitude, climatic belts are singled out – huge territories within which the main climate indicators hardly change. […]...
