Convection

-Air movement (wind)
-Formation of Clouds
-Precipitation

1. The uneven heating of the earth (equator = direct, poles = indirect)
2.The tilt/ angle of the Earth and its always moving southern hemisphere gets more sun
3. Rotation of the Earth (day / night)
4.Some surfaces absorb heat better than others (dark surfaces vs bright surfaces)

-Clouds
-Winds
-Fronts, caused by air movement

Over the warm surface emits heat warming the air. Causing it to rise. The air over the cool surface does not receive heat so it sinks and condenses. This makes it moved towards the lower air pressure.

During the night the sun is not heating the surface. The land can no longer heat the air causing the air to cool over the land. The water absorbed the sun's radiation and now emits the air causing the air to rise over the water.

They have the latitude lines labeled. It show the what the land look like at each latitude.

There are cold (high pressure) lines moving towards the center equator. There are warm (low pressure) lines being forces up and away from the equator.
