Question

Explain briefly but clearly, the process of evaporation and condensation.

Answer 1

Hint: The water cycle is a natural phenomenon and is known as the movement of water on, above, and below the surface of the Earth. The overall mass of water on Earth remains constant but the partitioning of water into rivers, oceans, sea, ice, and atmosphere depends on the climatic conditions.

Complete answer: Evaporation and Condensation are the processes that move the water from one reservoir to the other along with other processes. Evaporation is the process in which vaporization of water occurs. The surface of the liquid changes its state from water to gas and vaporizers into the atmosphere. Evaporation of water occurs when the surface of the water is exposed to the sun. The sun drives up the evaporation from oceans and other sources of water allowing molecules to escape in the form of vapor and the vapor forms clouds. Evaporation is faster on a dry and sunny day, with a clear sky. Condensation is the reverse of vaporization, it is the change in the physical state of matter from gaseous to liquid form. It is defined as the state when the water vapor changes to liquid water state when the vapor comes in contact with a liquid or solid surface within the atmosphere.

Note: The water moves from one place to another depending upon the climatic conditions. It goes through different forms: liquid, solid (ice) and gas. The physical processes which provide the movement of water from one place to another are evaporation, condensation, precipitation, infiltration, surface runoff, and subsurface flow.
