Weather is caused by the rising and falling of warm and cool air called ( ). These currents affect the different air pressures in the atmosphere( ) . Response area occurs when the air cools and begins to sink, while ( ) occurs when the air warms and begins to rise. The differences between these pressures are what causes ( ). Convection can also create ( ) in a small local area.
