Why is the water cycle available on earth and water move between the hydrosphere and the atmosphere during the water cycle?
Dear Rk Naresh ,
The global water cycle is driven by solar energy heating up the surface water resulting in evaporation followed by cooling, condensing and freezing into clouds of ice crystals at high altitude and finally these ice crystals conglomerate and precipitate as snow, hail and rain. This closes the water cycle. Due the current global warming this global water cycle is getting more intense as a result of the higher evaporation rate.
Yes, the hydrosphere and atmosphere work together to move water around Earth in a process known as the water cycle or hydrological cycle. This cycle involves the continuous movement of water between the hydrosphere (water bodies), atmosphere (air), and other components of the Earth system. The water cycle is an extremely important process because it enables the availability of water for all living organisms and regulates weather patterns on our planet. If water didn't naturally recycle itself, we would run out of clean water, which is essential to life. Liquid water from oceans, lakes and rivers rises via evaporation into the sky, to form water vapor, an important greenhouse gas that, like carbon dioxide, helps insulate the planet to maintain that “just right” temperature to maintain life as we know it. Water moves through the hydrosphere in a cycle. Water collects in clouds, and then falls to Earth in the form of rain or snow. This water collects in rivers, lakes and oceans. Then it evaporates into the atmosphere to start the cycle all over again. Evaporation shows interactions between the hydrosphere and atmosphere because it is the reason that water leaves the hydrosphere and enters the atmosphere as a part of the water cycle. The hydrosphere is all of the bodies of water on Earth, including oceans, lakes and rivers. The water cycle shows the continuous movement of water within the Earth and atmosphere. It is a complex system that includes many different processes. Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow. In particular, evaporation exceeds precipitation over the oceans, which allows moisture to be transported by the atmosphere from the oceans onto land where precipitation exceeds evapotranspiration, and the runoff flows into streams and rivers and discharges into the ocean, completing the cycle. Water at the surface of the ocean, rivers, and lakes can become water vapor and move into the atmosphere with a little added energy from the Sun through a process called evaporation. Snow and ice can also turn into water vapor, which is a process as sublimation. The water cycle describes how water is exchanged (cycled) through Earth's land, ocean, and atmosphere. Water always exists in all three phases, and in many forms as lakes and rivers, glaciers and ice sheets, oceans and seas, underground aquifers, and vapor in the air and clouds.
