The cycle of water between the ocean atmosphere and land
34
Frontal rainfall

36
Convective rainfall
1) sun provides heat source heating the ground quickly 2) air rises very quickly through convection currents 3) as the air rises it cools rapidly 4) large clouds develop above the rising air as the air can't hold as much water 5) torrential rain and thunderstorms are produced
