Trade winds are caused by the convection of heat on a global scale. At the equator, the intense sun heats the air, causing it to rise. As this air moves up, cooler air from the subtropics flows in along the ...
Atmospheric air is held to the Earth by the force of gravity. Just as gravity keeps our feet on the ground and prevents the oceans from floating away, it also pulls on every molecule of gas in the air. This ...
A sea breeze blows during the day because land heats up much faster than the ocean. As the warm air over the land rises, it creates a small area of low pressure. The cooler, heavier air over the sea then ...
