If it didn't, the Earth would keep getting hotter and hotter. We would have to find a way to get rid of some of the heat. As it is, we have roughly an energy balance where we retain about as much energy as leaves the system, and that keeps temperature roughly constant.
In Earth Science, it means Incoming Solar Radiation.

Just as the Earth's Nitrogen cycle and its Carbon cycle are cyclic, the Earth's Water Cycle is just that; Water Vapor returns to the Atmosphere to complete the Cycle.

When Earth revolves around the sun different areas will get different amounts of insolation. For example, in the Northern Hemisphere our winter days are shorter and summers are longer.
