Evaporation in Water Cycle

Water is essential to sustain life on Earth.

The water cycle is responsible for maintaining the water level and the climate.

The steps involved in Water Cycle are Evaporation Transpiration Condensation Precipitation Runoff

We will discuss about Evaporation,which is an important step in the water cycle.

Evaporation is the process by which water changes from a liquid to vapor.

For the functioning of water cycle, water has to move from the Earth's surface into the skies.

It is the process of evaporation that changes liquid to water-vapor ,which rises up into the sky to become clouds.

Now we will understand about evaporation.

For water to evaporate heat energy is required to break the bonds that hold water molecules together.

Water easily evaporates at the boiling temperature of 100° C.

Let us see a real-life example of evaporation

Making salt from sea-water is a perfect example of how evaporation plays an important role in our day to day activity.

Sea water contains high concentration of salt. If the water is evaporated, only then salt crystals remain.

Let us study the role of evaporation in water cycle

Evaporation of water from ocean and other surface water bodies is the main source for obtaining water-vapour.

Evaporation from the oceans is the primary mechanism for the surface-to-atmosphere transfer of water for the water cycle.

Once evaporated, a water molecule spends some time in the air, in the form of clouds.

Moving on, let us discuss the factors affecting evaporation

Temperature is one of the factors affecting evaporation. The rate of evaporation increases with the increase in temperature.

Surface area is another factor. Increase in surface area results in increase in evaporation.

Increase in atmospheric humidity results in decrease in rate of evaporation.

Revision

Evaporation is an important step in the water cycle.

Evaporation is the process by which liquid turns to gas.

In water cycle, evaporation is the step that converts water to watervapor gas.

Water evaporates from ocean and other surface water bodies.

Factors affecting evaporation are temperature, surface area, humidity, and wind speed.
