The air is full of water, as water vapor, even if you can't see it. Condensation is the process of water vapor turning back into liquid water, with the best example being those big, fluffy clouds floating over your head.
And when the water droplets in clouds combine, they become heavy enough to form raindrops to rain down onto your head. You can't see it, but a large portion of the world's freshwater lies underground. It may all start as precipitation, but through infiltration and seepage, water soaks into the ground in vast amounts. Water in the ground keeps all plant life alive and serves peoples' needs, too. Note: This section of the Water Science School discusses the Earth's "natural" water cycle without human Ice and glaciers are part of the water cycle, even though the water in them moves very slowly.
Ice caps influence the weather, too. The color white reflects sunlight heat more than darker colors, and as ice is so white, sunlight is reflected back out to the sky, which helps to create weather patterns. Read on to learn how glaciers and ice caps are part of the water cycle. Yes, water below your feet is moving all the time, but, no, if you have heard there are rivers flowing below ground, that is not true. Water moves underground downward and sideways, in great quantities, due to gravity and pressure.
Eventually it emerges back to the land surface, into rivers, and into the oceans to keep the water cycle going. Evapotranspiration can be defined as the sum of all forms of evaporation plus transpiration, but here at the Water Science School, we'll be defining it as the sum of evaporation from the land surface plus transpiration from plants. Freshwater on the land surface is a vital part of the water cycle for everyday human life.
On the landscape, freshwater is stored in rivers, lakes, reservoirs, and creeks and streams. Most of the water people use everyday comes from these sources of water on the land surface. Here is a classic rainstorm during the summer, as that is when more localized storms occur. Other rain events are more "frontal" in nature, with large formations of featureless and uniform nimbostratus types of clouds bringing precipitation over a large area. But often you see a landscape similar to.
When the cloud droplets combine to form heavier cloud drops which can no longer "float" in the surrounding air, it can start to rain, snow, and hail. Skip to main content. Search Search.

Water is in the atmosphere, on the land, in the ocean, and underground.
It moves from place to place through the water cycle. There are about 1. That includes liquid water in the ocean, lakes, and rivers. If you could put all that water together — like a gigantic water drop — it would be 1, kilometers miles across. Sometimes the ice on Earth is included in the hydrosphere and sometimes it's seperated into a special part of the Earth system called the cryosphere. Most of the ice is in Antarctica, a smaller amount in Greenland in the Arctic, and a tiny fraction in mountain glaciers around the world.
Only a small fraction of the water on Earth 0. As it moves through the water cycle, water often changes from a liquid, to a solid ice , to a gas water vapor. Water in oceans and lakes is typically liquid; but it is solid ice in glaciers, and often invisible water vapor in the atmosphere. Clouds are tiny droplets of liquid water or small ice crystals. Water at the surface of the ocean, rivers, and lakes can become water vapor and move into the atmosphere with a little added energy from the Sun through a process called evaporation.
Snow and ice can also become water vapor through a process called sublimation. And water vapor gets into the atmosphere from plants by a process called transpiration. Because air is cooler at higher altitude in the troposphere , water vapor cools as it rises high in the atmosphere and transforms into water droplets by a process called condensation. The water droplets that form make up clouds. Water vapor can also condense into droplets near the ground, forming fog when the ground is cold.
May 29, Explanation: The Water Cycle is a description of how water moves - it describes the movement of water into the atmosphere evaporation , the formation of clouds condensation , the movement of water through the air via clouds and wind currents transportation , the fall of water in the form of rain and snow precipitation and transportation back to rivers and oceans.
