During evaporation, water rises into the atmosphere and condenses into clouds. When the clouds absorb too much moisture and become heavy, the moisture falls to the ground in the form of precipitation. This is known as the water cycle, which involves evaporation, condensation and precipitation.Continue Reading
The water cycle starts when water evaporates from the ocean surface. Moisture rises and cools, and water vapor forms clouds. Soon, moisture returns to the ground through precipitation. Once water reaches the surface, some of it tends to evaporate back into the air. It also sometimes penetrates the surface and becomes groundwater, which seeps into rivers, streams and oceans. At times, water gets released back into the atmosphere via transpiration, which is the process of water evaporating into the air from the leaves and stems of plants.
Evaporation is the process of liquids changing into gas. It occurs when liquids are either cool or warm. Oftentimes, evaporation happens when liquids are warm. Through the water cycle, water is never lost; it is constantly changed to different forms.
Most of the water that evaporates into the air comes from oceans. Liquids from plants and soil also rise into the atmosphere and form clouds. Snow and ice evaporate even without melting first through sublimation, which is the process of transitioning directly from solid to gas with no intermediate liquid phase.Learn more about States of Matter
Pure water freezes at 0 degrees Celsius at 1 atmosphere of pressure. The freezing point of salt water is lower and depends on the concentration of salt.Full Answer >
According to Met Office, clouds form when water vapor in the air condenses into tiny drops of water or ice crystals that then settle on dust particles in the atmosphere. Condensation happens when the air is saturated and cannot hold any more water vapor; this can occur when the amount of water in the air increases or when the air is cooled to its dew point.Full Answer >
The water, or hydrologic, cycle has only a few basic steps, beginning with evaporation of the water in rivers, lakes and oceans into water vapor, which then condenses into clouds. When enough water vapor condenses in the clouds, it then turns into either liquid water or ice. This then falls back to the ground through precipitation as either snow or rain, which will eventually evaporate again.Full Answer >
Bodies of water on Earth are maintained by the atmosphere keeping the water cycle of evaporation, condensation and precipitation functioning so that water can be replenished. Also, the gravitational pull of the Earth keeps water from leaving the planet.Full Answer >
