Question

Explain the process involved in water cycle

Answer 1

Water cycle, also called hydrologic cycle, cycle that involves the continuous circulation of water in the Earth-atmosphere system. Of the many processes involved in the water cycle, the most important are evaporation, transpiration, condensation, precipitation, and runoff.

evaporation = Evaporation happens when a liquid substance becomes a gas. When water is heated, it evaporates. The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor. Evaporation is a very important part of the water cycle.

transpiration = Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere. Transpiration is essentially evaporation of water from plant leaves.

condensation = The Water Cycle. Condensation is the process by which water vapor in the air is changed into liquid water. Condensation is crucial to the water cycle because it is responsible for the formation of clouds.

precipitation = Precipitation is water released from clouds in the form of rain, freezing rain, sleet, snow, or hail. It is the primary connection in the water cycle that provides for the delivery of atmospheric water to the Earth. Most precipitation falls as rain.

runoff =  Runoff can be described as the part of the water cycle that flows over land as surface water instead of being absorbed into groundwater or evaporating. Runoff is that part of the precipitation, snow melt, or irrigation water that appears in uncontrolled surface streams, rivers, drains, or sewers.

hope this works out !!!!

Answer 2

Answer:

The water cycle demonstrates how water is constantly moving both inside the Earth and in the atmosphere.

Explanation:

• Water molecules on the surface of water bodies typically evaporate when they become agitated and rise into the air.
• Clouds of water vapour are formed when these molecules with the highest kinetic energy gather.
• The low temperatures at high altitudes cause the water vapour that has accumulated in the atmosphere to finally cool down.
• These vapours eventually condense into small water and ice droplets that produce clouds.
• It drops from the clouds and lands on the ground below when enough droplets combine.
• Precipitation is the term for this action (or rainfall).
• The water droplets freeze and fall as snow or hail when it is unusually cold outside or when there is a dramatic reduction in air pressure.
• Through a process called infiltration, rainwater is absorbed into the soil.
• If rainwater does not create aquifers, it usually flows downwards along the slopes of mountains and hills, finally forming rivers. This procedure is known as runoff.
• Each of the aforementioned processes happens repeatedly with neither a set beginning nor end.

The water cycle can be summed up as follows: Water vapour is created when liquid water evaporates, condenses to form clouds, and then falls back to earth as rain and snow.
