The water vapors being lighter than air rise up and go into the atmosphere.<\/p>\n\n\n\n<p>(b) <strong><em>Sublimation-<\/em><\/strong> Sublimation is a conversion of solid to gas, without passing through the intermediate liquid phase. Ice sheets and ice caps from the north and south poles, and icecaps on mountains, get converted into water vapor directly, without converting into liquid.<\/p>\n\n\n\n<p>(c) <strong><em>Absorption and Transpiration by Plants-<\/em><\/strong> Plants absorb water continuously from the soil with the help of their roots. Part of this water is utilized for photosynthesis. The remaining water which is not used by the green plants is given off into the atmosphere by transpiration (the loss of water from the aerial parts of a plant, mainly leaves in the form of water vapor is called transpiration).<\/p>\n\n\n\n<p>Transpiration is responsible for the huge loss of water from plants and indirectly from the soil. In fact, transpiration is the major source of water vapor in the atmosphere. Respiration by plants and the decay of dead plants also release water vapor into the atmosphere.<\/p>\n\n\n\n<p>(d) <strong><em>Consumption and Release of Water by Animals-<\/em><\/strong> Animals consume drinking water from various sources like ponds, wells, lakes, rivers, etc. Animals also take in some water by feeding on plants directly or indirectly. Animals release water vapor into the atmosphere by breathing, evaporation of water from their body surface, excretion, and by decay of their dead bodies.<\/p>\n\n\n\n<p>(e) <strong><em>Condensation-<\/em><\/strong> Water vapors being lighter than air, rise in the air and go high up in the atmosphere. As the vapors rise, they get cooled and condense to form tiny droplets to form the cloud.<\/p>\n\n\n\n<p>(f) <strong><em>Ground Water-<\/em><\/strong> The tiny droplets of water in the cloud join together to form bigger drops of water. These fall on the earth in the form of rain. A major part of the rainwater falling on earth goes into the ponds, lakes, rivers, and oceans. Some of the rainwater is absorbed by the soil. In the soil, it is retained as soil water. In cold regions, during winters, water falls down in the form of snow. In this way, the water which was lost as water vapor from the earth returns to the earth (both in soil and water bodies) and the water cycle is completed.<\/p>\n\n\n\n<p><strong><em>Thus, in nature, there is a circulation of water and moisture that is maintained between living organisms, the atmosphere, and the earth. This is known as the water cycle or hydrological cycle.<\/em><\/strong> Water is an important as well as a significant environmental factor. Without a hydrological cycle, biological cycles could not occur, <a href=\"https:\/\/alaskaglobe.com\/ecosystem\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong><em>ecosystems<\/em><\/strong><\/a> could not function and life could not be sustained.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Regulation_of_Hydrological_Cycle_by_Forests\"><\/span>Regulation of Hydrological Cycle by Forests:<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Forests contain a large number of trees and other plants. A large amount of soil water is transferred to the atmosphere by transpiration in the form of water vapor. More water vapor in the atmosphere brings down more rain on the earth. If forests are cut or destroyed in an area, less rain will take place in that area. Thus forests help in bringing more rainfall to an area and regulate the hydrological cycle.<\/p>\n\n\n\n<hr class=\"wp-block-separator aligncenter has-alpha-channel-opacity is-style-wide\"\/>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td><a href=\"https:\/\/alaskaglobe.com\/darwinism\/\" target=\"_blank\" rel=\"noreferrer noopener\">Darwinism or Theory of Natural Selection<\/a><br><a href=\"https:\/\/alaskaglobe.com\/computer-network\/\" target=\"_blank\" rel=\"noreferrer noopener\">Computer Network<\/a><br><a href=\"https:\/\/alaskaglobe.com\/pleasure-of-reading\/\" target=\"_blank\" rel=\"noreferrer noopener\">Pleasure of Reading<\/a><br><a href=\"https:\/\/en.wikipedia.org\/wiki\/Water_cycle\" target=\"_blank\" rel=\"noreferrer noopener\">Read More About Hydrological Cycle or Water Cycle<\/a>&#8211; Wikipedia<\/td><\/tr><\/tbody><\/table><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Hydrological Cycle: Water is indispensable for life.
