What is it cycle also known as Hydrological

What is it? cycle also known as Hydrological cycle or Water Hydrolic cycle is the continuous movement of water on above or below the surface of land. Water never leaves the Earth. It is constantly being cycled through the atmosphere, ocean, and land. This process, known as the Water Cycle, is driven by energy from the sun. The hydrologic cycle has a profound effect upon climate prediction. Branch of science to study the movements and characteristics of water under of over surface or earth is called Hydrology.

Evaporation Evapotranspirati on Condensati on Precipitatio n Interception Infiltration

Evaporation occurs when water changes from liquid state to gaseous state. Evaporation occurs on water surfaces like lakes, seas etc. Evaporated

Evapo-transpiration is water evaporating from the ground and transpiration by plants. Evapo-transpiration is also the way water vapour-enters the atmosphere About 90% of atmospheric water comes from evaporation, while the remaining 10% is from transpiration. Water is evaporated from lakes, streams, oceans,

CONDENSATI ON

Condensation is the process by which water vapor changes into water. Water vapor condenses to form dew, fog or clouds. Condensation takes place due to cooling of air. As water (in the form of gas) rises higher in the atmosphere, it starts to cool and become a liquid again. When a large amount of water

Condensation can form: Fog, Dew, and Clouds Fog: Fog forms when air near the surface is cold and nearly saturated with water. Now when water from the ground evaporates, it condenses immediately forming tiny water droplets that create a low-lying cloud we call fog. Dew: Dew forms at night when air becomes saturated with water vapor. When this saturated air comes in contact with plants or other objects it condenses, leaving tiny water droplets behind on the object. Clouds: When the air containing water vapor is heated by the sun, it rises into the atmosphere by convection. The water vapor in the air is then cooled by the colder air higher in the atmosphere causing the relative humidity to increase. As the relative humidity increases, the air eventually becomes

Transpiration occurs when plants take in water through the roots and release it through the leaves, a process that can clean water by removing contaminants and pollution. Transpiration is the biological process that occurs mostly in the day. Water inside plants is transferred to the atmosphere as water vapor.

When the water in the clouds gets too heavy, the water falls back to the earth. This is called precipitation. Precipitation is the process that occurs when water particles fall from the atmosphere and reach the ground. Precipitated water may fall into water bodies or on land. It can then go to streams or penetrate into the

Interception refers to precipitation that does not reach the soil, but is instead intercepted by the leaves and branches of plants and the forest floor.

INFILTRATI Some precipitation seeps into the groundwater and is stored ON in layers of rock below the surface of the Earth. This water stays there for varying amounts of time. Some water may evaporate into the hydrologic cycle within days, while other water will stay in the ground for centuries or more. This process of precipitation seeping into the groundwater is called infiltration. It is measured in inches per hour or millimeters per hour.

RUNOFF Runoff is precipitation that did not get absorbed into the soil, or did not evaporate. Runoff causes erosion, and also carry chemicals and substances on the ground surface.

There are three basic water storage places: in atmosphere, on earth’s surface, and in the ground. Surface storage places are: ocean, lake, reservoirs, glaciers. Underground storage
