The water cycle is driven primarily by the energy from the sun. This solar energy drives the cycle by evaporating water from the oceans, lakes, rivers, and even the soil. Other water moves from plants to the atmosphere through the process of transpiration.

Evaporation

Condensation – First, the water vapor condenses. Condensation is the change of water from gas form to liquid form. When water vapor in the atmosphere loses heat and cools down, condensation happens.

There are four main parts to the water cycle: Evaporation, Convection, Precipitation and Collection.

The water cycle is defined as a natural process of constantly recycling the water in the atmosphere. It is also known as the hydrological cycle or the hydrologic cycle. During the process of the water cycle between the earth and the atmosphere, water changes into three states of matter – solid, liquid and gas.

The carbon cycle describes the process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. Carbon is released back into the atmosphere when organisms die, volcanoes erupt, fires blaze, fossil fuels are burned, and through a variety of other mechanisms.

Of the many processes involved in the water cycle, the most important are evaporation, transpiration, condensation, precipitation, and runoff. Although the total amount of water within the cycle remains essentially constant, its distribution among the various processes is continually changing.

The hydrologic cycle, or water cycle, essentially explains the processes water goes through to get from evaporation to rain to our drinking water. Teaching the water cycle for kids will help them better understand the importance of our drinking water supply as well as important processes that the earth goes through.

They are evaporation, condensation, precipitation and collection. Let’s look at each of these stages.

three phases

Three States of Water The three phases are solid (ice or snow), liquid (water), and gas (water vapor).

Water cycle processes include evaporation, condensation, convection, precipitation, freezing and melting, groundwater flow, and runoff. Evaporation is the conversion of water from a liquid to a gas.

The continuous movement of water on, above and below the surface of earth is known as hydrological cycle. The freshwater is mainly obtained from surface run off and ground water that is continually being renewed and recharged through the hydrological cycle. All water moves within the hydrological cycle Q.

HelpCenter Definition. The water cycle — technically known as the hydrological cycle — is the continuous circulation of water within the Earth’s hydrosphere, and is driven by solar radiation. This includes the atmosphere, land, surface water and groundwater.

Hydrological cycle is also known as the “water cycle”; it is the normal water recycling system on Earth (Fig. 3.4). Precipitation falls on the earth as surface water and shapes the surface, creating thus streams of water that result in lakes and rivers.

The constant flow of water from the Earth to the atmosphere and back to the Earth is known as the water cycle. The two main steps involved in water cycle are evaporation and condensation. Evaporation is the process in which water changes into vapour due to the heat of the Sun.

Water cycle is important because of the following reasons: (1) Water cycle makes fresh water available in the form of rain: The sea-water is highly salty which is not fit for drinking by animals or for the growth of plants. But the rain water is pure water.

c) Condensation – The evaporated water is carried away by warm air. As the warm air moves higher from the surface of the Earth, it starts to cool down. This water vapour condenses to form tiny water droplets which float in air to form clouds or fog.
