Answers are in bold.

1. Energy from the sun is transferred to Earth's surface. Some of that energy is then transferred to the air above the surface.

2. The closer a location is to the equator the more energy it receives from the sun. Therefore a location's air temperature is affected by its distance from the equator.

3. An effect may have more than one cause. These may be linked into a chain of causes and effects.
