What is the water cycle? I can easily answer that-it is "me" all over! The water cycle describes the existence and movement of water on, in, and above the Earth. Earth's water is always in movement and is always changing states, from liquid to vapor to ice and back again. The water cycle has been working for billions of years and all life on Earth depends on it continuing to work; the Earth would be a pretty stale place without it. Where does all the Earth's water come from? Primordial Earth was an incandescent globe made of magma, but all magmas contain water. Water set free by magma began to cool down the Earth's atmosphere, and eventually the environment became cool enough so water could stay on the surface as a liquid. Volcanic activity kept and still keeps introducing water into the atmosphere, thus increasing the surface- and groundwater volume of the Earth. The water cycle has no starting point, but we'll begin in the oceans, since that is where most of Earth's water exists. The sun, which drives the water cycle, heats water in the oceans. Some of it evaporates as vapor into the air; a relatively smaller amount of moisture is added as ice and snow sublimate directly from the solid state into vapor. Rising air currents take the vapor up into the atmosphere, along with water from evapotranspiration, which is water transpired from plants and evaporated from the soil. The vapor rises into the air where cooler temperatures cause it to condense into clouds. Air currents move clouds around the globe, and cloud particles collide, grow, and fall out of the sky as precipitation. Some precipitation falls as snow and can accumulate as ice caps and glaciers, which can store frozen water for thousands of years. Snowpacks in warmer climates often thaw and melt when spring arrives, and the melted water flows overland as snowmelt. Most precipitation falls back into the oceans or onto land, where, due to gravity, the precipitation flows over the ground as surface runoff. A portion of runoff enters rivers in valleys in the landscape, with streamflow moving water towards the oceans. Runoff, and groundwater seepage, accumulate and are stored as freshwater in lakes.
Studying the water cycle is important to understand how water moves through the Earth's systems, from the atmosphere to the land and oceans. This knowledge is crucial for managing water resources, predicting weather patterns, and addressing issues like droughts and flooding. By understanding the water cycle, we can better protect and sustainably manage this vital resource.
The two processes that cycle water from land to the atmosphere are:1. Evaporation2. Condensation
The water cycle renews the supply of fresh water on land.
It's a part in water cycle, that takes place when water from the atmosphere is coming back to the land.
The constant movement of water through the Earth's system in a continuous cycle is known as the water cycle. This cycle involves processes such as evaporation, condensation, precipitation, and runoff, allowing water to move between the atmosphere, land, oceans, and living organisms. It plays a crucial role in maintaining Earth's ecosystems and supporting life.
The water cycle
Surface run off is water that runs over the surface of the land. Generally the soil has been infiltrated to full capacity. Channel run off is water in rivers, streams and channels.
We never run out of water, because of the water cycle.

yes, because the water cycle is constant, and if water that evaporates in the sea travels as water vapour over land and rains then the rain can soak in and run back to lakes as water underground.(throughflow)
