Homework Help: SCIENCE (correct I hope)

Summarize the hydrologic cycle. How important is this cycle to Earth?

The hydrologic cycle is a circulation of water from the oceans to the atmosphere and land, and back to the oceans. The hydrologic cycle starts with evaporation of water which comes from the oceans. The air currents carry the water vapor over land. Some of it falls to the ground which we know it as rain or snow; some of this water runs over the land to streams that flow back to the oceans. This is called a surface run off. Precipitation may fall right away back to the oceans; precipitation may also evaporate before it reaches the ground. Evaporation removes the water from soil, lakes, and streams turn it into the atmosphere.
