â¢ Winds blow from areas of high pressure to areas of low pressure. â¢ Pressure belts are caused by the uneven heating of Earthâs surface by the sun. â¢ The Coriolis effect causes wind to appear to curve as it moves across Earthâs. surface. â¢ Global winds include the polar easterlies, the westerlies, and the trade winds.
1 Heating of the surface of the Earth results in the formation of clouds. 2  When the ground heats up due to the heat of the Sun, it in turn heats the air around it. 3  This warm air due to heating thus reduces in density, and becomes lighter. 4  Because it becomes lighter, it begins to rise up in the atmosphere.
