Water

4 Processes

Evaporation

Factors which affect evaporation

Temperature of surroundings

Presence of Wind

Surface Area exposed to air

Humidity

Evaporation is the process by which water
changes from a liquid to a gas or water vapour

Precipitation

Precipitation is any form of liquid or solid water particles that fall from the atmosphere and reach the surface of the Earth. Precipitation can fall as rain, snow, hail and sometimes even sleet

Transpiration

Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves(stomata), where it changes to vapor and is released to the atmosphere.

Condensation

Condensation is the process by which water vapor in the air is changed into liquid water droplets upon contact with a cooler surface

Difference between Boiling and Evaporation of Water

Evaporation happens at 0 degrees Celsius to right before 100 degrees Celsius, but boiling happens at 100 degrees Celsius.When Evaporation happens, there will be water vapour evaporating from the water. But when it is boiling, water would change into its gaseous sate and become steam.

Terrarium

A Terrarium(bottled garden)can be used to represent the processes in the water cycle.

Water Cycle

A process where water circulates continuously between the bodies of water, atmosphere and land.

The total amount of water in the earth's atmosphere remains constant.

The Water Cycle is a natural system whereby water moves from the atmosphere to the land and back up again. Almost all the water on Earth is part of the water cycle.

What Does the Water Cycle help us in?

Ensure that living things have a continuous supply of fresh water for survival.

Purifying our water before returning it to land.

To regulate the temperature on Earth.

Difference between Water Vapour and Steam

Water Vapour is the product of the evaporation of water from 1 to 99 Degrees Celsius, while Steam is the product of boiling water at 100 Degrees Celsius.
