4. Greenhouse gases block heat from transmitting back to space. Four important greenhouse gases are
water vapor, carbon dioxide, methane, and nitrous oxide

On the earth, the effect tends to deflect moving objects to the right in the northern hemisphere and to the left in the southern and is important in the formation of
cyclonic weather systems.

6. Winds form partly because of
air along the equator absorbing solar radiation and rising.

7. Wind is the movement of the molecules in the air. Winds in our atmosphere are driven by
heat energy from the Sun.
