1. when looking at a satellite image, do clear areas (no clouds) signify rising air or sinking air? 2. what direction does air move around an area of high pressure? 3. what direction does air move around an area of low pressure? 4. what is a cold front? 5. what is a warm front?

1. Clear area signify sinking air.
Sinking air is created through divergence of air at the surface out the areas with high pressures.
If being observed through satellite, the process would cause the sky area to become more clear with no clouds spotted.

2. The answer is clockwise.
This happens because of the Coriolis effect. As the earth rotates,  The spin will create the wind to Curve to the right. This will lead to winds blow clockwise around within the area that has high pressure

3 The answer is Counterclockwise
The explanation is similar to number 2 but now it has to counter the opposite direction, which also cause the opposite direction of the air movement.

4. Cold front is the movement of mass of cold air, which trails from the sector of low temperature (and low pressure system). It usually move from northwest to southeast and will decrease the average temperature of the region that it passed.

5. Warm front is the movement of mass of warm air and will create a transition to replace the cold air. It usually move move from southwest to northeast and will increase the average temperature of the region that it passed (which will create perfect condition for many type of plants to grow)
