noun
- 1. the cycle of processes by which water circulates between the earth's oceans, atmosphere, and land, involving precipitation as rain and snow, drainage in streams and rivers, and return to the atmosphere by evaporation and transpiration.

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.
May 17, 2023 · Water cycle, also known as the hydrologic cycle, involves a series of stages that show the continuous movement and interchange of water between its three phases – solid, liquid, and gas, in the earth’s atmosphere.
The water cycle (or hydrologic cycle or hydrological cycle), is a biogeochemical cycle that involves the continuous movement of water on, above and below the surface of the Earth. The mass of water on Earth remains fairly constant over time.
The water cycle is the continuous movement of water from the earth to the atmosphere. It is also called the hydrologic cycle, which plays an important role in the maintenance of lives and ecosystems on the planet.
May 16, 2020 · The water cycle or hydrologic cycle describes the complex systems that allow water to move across the Earth and atmosphere. The most basic step of the water cycle is the change of state of water as a liquid, gas or solid in the atmosphere.
Apr 29, 2024 · 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 Earth’s oceans, land, and atmosphere. Earth’s water cycle began about 3.8 billion years ago when rain fell on a cooling Earth, forming the oceans.
Jun 26, 2024 · 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.
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.
Oct 19, 2023 · The water cycle describes how water is exchanged (cycled) through Earth's land, ocean, and atmosphere. Water always exists in all three phases, and in many forms—as lakes and rivers , glaciers and ice sheets , oceans and seas, underground aquifers , and vapor in the air and clouds .
At its most basic, the water cycle is how water continuously moves from the ground to the atmosphere and back again. As it moves through this cycle, it changes forms. Water is the only substance that naturally exists in three states on Earth – solid, liquid, and gas.
