Water cycle, cycle that involves the continuous circulation of water in the Earth-atmosphere system. Of the many processes involved in the water cycle, the most important are evaporation, transpiration, condensation, precipitation, and runoff. The total amount of water remains essentially constant.

About 75 percent of our planet is covered by water or ice. The water cycle is the endless process that connects all of that water. It joins the Earth?s oceans, land, and atmosphere. The Earth?s water cycle began about 3.8 billion years ago when rain fell on a cooling Earth, forming the oceans.

The water cycle, or hydrologic cycle, is driven by the Sun?s energy. The sun warms the ocean surface and other surface water, causing liquid water to evaporate and ice to sublime?turn directly from a solid to a gas. These sun-driven processes move water into the atmosphere in the form of water vapor.

The water cycle involves the exchange of energy, which leads to temperature changes. When water evaporates, it takes up energy from its surroundings and cools the environment. When it condenses, it releases energy and warms the environment. These heat exchanges influence climate .

The water cycle shows the continuous movement of water within the Earth and atmosphere. It is a complex system that includes many different processes. Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow.

We will drink some of this fresh water, our bodies are actually mostly water. The cells in our bodies are 70% water. Everything we study in biology, water is a key environment for all of these things to occur. And then we use that water, and then we will get that water out of our body, and then it continues on as part of this water cycle.

The water cycle describes how water evaporates from the surface of the earth, rises into the atmosphere, cools and condenses into rain or snow in clouds, and falls again to the surface as precipitation.

Credit: NASA. The water cycle describes where water is on Earth and how it moves. Water is stored in the atmosphere, on the land surface, and below the ground. It can be a liquid, a solid, or a gas. Liquid water can be fresh or saline (salty). Water moves between the places it is stored.

The water cycle consists of three major processes: evaporation, condensation, and precipitation. Evaporation. Evaporation is the process of a liquid's surface changing to a gas. In the water cycle, liquid water (in the ocean, lakes, or rivers) evaporates and becomes water vapor. Water vapor surrounds us, as an important part of the air we breathe.

What Is the Water Cycle? | NASA Climate Kids

The Short Answer: The water cycle is the path that all water follows as it moves around Earth in different states. Liquid water is found in oceans, rivers, lakes?and even underground. Solid ice is found in glaciers, snow, and at the North and South Poles. Water vapor?a gas?is found in Earth?s atmosphere.
