Water Cycle Quiz

The water cycle helps to maintain the Earth's climate by transporting energy around the planet.

The sun provides warmth and light that is necessary for life on Earth. This energy travels through the atmosphere and warms the surface of the Earth. Some of this energy escapes back into space, while some is used to evaporate water from lakes, oceans, and other sources. When water vapor rises into the air, it carries with it the heat that was originally absorbed from the sun.

This process helps to cool down the Earth's surface temperature. As precipitation falls back to Earth, it brings with it new moisture that helps to regulate temperatures in different parts of the world.

The water cycle is usually portrayed as a simple circular cycle of evaporation, condensation, and precipitation. Although this may be an effective metaphor, the reality is considerably more complex. Water's pathways and effects in Earth's ecosystems are quite intricate, and their nature isn't completely known.
