What is 10th water cycle?
The water cycle, also known as the hydrologic or hydrological cycle, is the continuous movement of water on, above, and beneath the Earth's surface. Water changes state from one phase to another during this process, but the total number of water particles remains constant.
What is water cycle for kids?
The Short Answer: The water cycle is the path that all water follows as it moves around Earth in different states. Liquid water is found in oceans, rivers, lakes—and even underground. Solid ice is found in glaciers, snow, and at the North and South Poles. Water vapor—a gas—is found in Earth's atmosphere.

How does the water cycle start?
The water cycle starts with evaporation. It is a process where water at the surface turns into water vapours. Water absorbs heat energy from the sun and turns into vapours. Water bodies like the oceans, the seas, the lakes and the river bodies are the main source of evaporation. Through evaporation, water moves from hydrosphere to atmosphere. As water evaporates it reduces the temperature of the bodies.
How does water enter the biosphere?
As water precipitates, some of it is absorbed by the soil. This water enters into the process of transpiration. Transpiration is a process similar to evaporation where liquid water is turned into water vapor by the plants. The roots of the plants absorb the water and push it toward leaves where it is used for photosynthesis. The extra water is moved out of leaves through stomata (very tiny openings on leaves) as water vapor. Thus water enters the biosphere and exits into gaseous phase.
What happens to water droplets at high altitudes?
At high altitudes the temperature is low and hence the droplets lose their heat energy. These water droplets fall down as rain. If the temperature is very low (below 0 degrees), the water droplets fall as snow. Water also precipices in the form of drizzle, sleet and hail.
How does sublimation affect water vapor?
This phenomenon accelerates when the temperature is low or pressure is high.
Why do clouds pour down?
4: Precipitation. The clouds (condensed water vapors) then pour down as precipitation due to wind or temperature change. This occurs because the water droplets combine to make bigger droplets. Also when the air cannot hold any more water, it precipitates.
What happens when water pours down?
As the water pours down (in whatever form), it leads to runoff. Runoff is the process where water runs over the surface of earth. When the snow melts into water it also leads to runoff. As water runs over the ground it displaces the top soil with it and moves the minerals along with the stream.
What is pure water?
The water seeps down and increases the level of ground water table. It is called pure water and is drinkable. The infiltration is measured as inches of water-soaked by the soil per hour. borehole PROCESSES OF WATER CYCLE 0 comment.

Introduction
Operation
- The water cycle processes involve evaporation, condensation, precipitation, interception, infiltration, percolation, transpiration, runoff, and storage.
Mechanism
- Evaporation takes place when water changes from its liquid state to vapor or gaseous state. A substantial heat amount is exchanged during the process, roughly 600 calories of energy per gram of water. In most cases, the solar radiation and additional causes such as the wind, vapor pressure, atmospheric pressure, and air temperature influence the amount of natural evaporatio…
Synthesis
- Condensation is the process whereby the water vapor changes from its gaseous physical state to liquid or crystal solid. The water vapor condenses on minute air particles due to the cooling of the air, freezing temperatures, or increased vapor amounts to the point of saturation in the upper stratospheres.
Formation
- The condensed vapor then forms fog, dew or clouds. When the condensed clouds, dew, and fogs become too large and heavy to remain suspended in the atmosphere, they fall back on earth as precipitation due to gravity. The 600 calories of energy per gram of water needed during evaporations are released into the environment. One falling particle leaves behind a turbulent wa…
Causes
- Precipitation takes place whenever any or all forms of water particles fall from the atmosphere and reach the earth surface. Precipitation occurs when the liquid or solid particles in the clouds, dew, and fog drops to the ground because of frictional drag and gravity.
Definition
- Interception is whereby the water movement is interrupted in the various paths during transportation events over the land surface. Interception takes place when the water is absorbed by vegetation cover and trees, absorbed into the ground, or stored in puddles and land formations such as furrows and streamlets. These waters can either infiltrate into the soil or return to the at…
Geology
- This area normally acts as reservoirs for storing water. Some geologic formations may conduct this water back to the surface such as springs.
Summary
- Runoff is the occurrence of excess water from watershed or drainage basin that flows on the surface. The flow is as a result of precipitation above waterways, groundwater runoff from deep percolations, subsurface runoff that infiltrates the surface soils, and surface runoff that flows on the land surface. As the water flows, it can be used for agricultural and domestic purposes, it m…
Nomenclature
- Storage refers to the various water reservoirs in the planetary water or hydrological cycle. The water is primarily stored in the atmosphere, the surface of the earth, and in the ground. Storage in the atmosphere is in the form of water vapor. Storage on the surface of the earth includes lakes, oceans, rivers, glaciers, and reservoirs. Storage in the ground pertains to the soils, rock formatio…
