What is the main cause of the water cycle?
The sun, which drives the water cycle, heats water in the oceans. Some of it evaporates as vapor into the air. The vapor rises into the air where cooler temperatures cause it to condense into clouds. Air currents move clouds around the globe, cloud particles collide, grow, and fall out of the sky as precipitation.
How does the water cycle happen?
The water cycle describes how water evaporates from the surface of the earth, rises into the atmosphere, cools and condenses into rain or snow in clouds, and falls again to the surface as precipitation.
What causes the water cycle to continue on earth?
Most of Earth’s water is in the oceans. The sun, which drives the water cycle, heats water in the oceans. Some of it evaporates as vapor into the air. A portion of runoff enters rivers and continues toward the oceans.
What is water cycle and its importance?
The hydrologic cycle is important because it is how water reaches plants, animals and us! Besides providing people, animals and plants with water, it also moves things like nutrients, pathogens and sediment in and out of aquatic ecosystems.
What are the 5 steps of the water cycle?
The entire process of water cycle takes place in almost five steps which includes the evaporation, condensation, precipitation, infiltration, and runoff. To begin with, water gets evaporated from the water bodies on the surface of earth like rivers, oceans etc. into the overlying atmosphere.
What is the water cycle, and how does it work?
Water cycle is also known as hydrologic cycle or hydrological cycle. It describes how water moves continuously on Earth. Water loops through different stages – evaporation, condensation, precipitation and flow. It then goes back to the evaporation stage.
What is the ultimate source of water cycle?
In the water cycle, the heat and light of solar energy cause water to melt or evaporate, changing the water from a solid or liquid form to a vapor. Although solar energy is the main energy source for the water cycle, many other kinds of energy are involved as water cycles among solid, liquid and vapor states.
How does the weather affect the water cycle?
Rainfall and snow are results of water cycle and can lead to severe weather conditions. Excessive rainfall due to water cycle can cause floods. Extremely low rainfall, lack of adequate water sources can lead to draught in a given region.
