WIND IN THE ATMOSPHERE

Air moves due to density differences from uneven heating of Earths surface. The sun warm up the Earth and causes circulation of air

Hi

Rising and sinking air in the atmosphere forms convection cells which create high and low pressure belts on earth

The differences in how earths land and water absorb and release energy. Resulting in the ways they absorb and release can cause sea and land breezes and mountain and valley breezes
