The hydrologic cycle

How do you define hydrologic cycle? What are the main components of hydrological cycle? Why is the water cycle important to an ecosystem?

The hydrologic cycle involves the continuous circulation of water in the Earth-Atmosphere system. At its core, the water cycle is the motion of the water from the ground to the atmosphere and back again.

The mass of water on Earth remains fairly constant over time but the partitioning of the water into the major reservoirs of ice, fresh water , saline water and atmospheric water is variable depending on a wide range of climatic variables. As moist air is lifte it cools and water vapor condenses to form clouds. Moisture is transported around the globe until it returns to the surface as precipitation. Environmental scientists know that the hydrologic cycle includes various processes that change water from solid to liquid to gas form and transport it to every corner of earth’s surface (and below).

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. The largest reservoir by far is the oceans, which hold about of Earth’s water.

Water in streams and rivers flows to the ocean, seeps into the groun or evaporates back into the atmosphere. Water in the soil can be absorbed by plants and is then transferred to the atmosphere by a process known as transpiration. This is a continuous cycle which starts with evaporation from the water bodies such as oceans. The water cycle describes the existence and movement of water on, in, and above the Earth.

Hydrologic cycle definition, the natural sequence through which water passes into the atmosphere as water vapor, precipitates to earth in liquid or solid form, and ultimately returns to the atmosphere through evaporation. Solar radiation that reaches Earth triggers the start of the hydrologic cycle by evaporating water. The most evaporation happens at the equator because it has the most sunlight. Hydrologic cycle definition is - the sequence of conditions through which water passes from vapor in the atmosphere through precipitation upon land or water surfaces and ultimately back into the atmosphere as a result of evaporation and transpiration —called also hydrological cycle. Here, the hydrologic cycle is upset: consumption (evaporation) is greater than recharge (precipitation).

For the people of arid regions, water and its conservation will become the most important consideration in the further development of these areas. Although the hydrologic cycle balances what goes up with what comes down, one phase of the cycle is frozen in the colder regions during the winter season. During the Canadian winter, for example, most of the precipitation is simply stored as snow or ice on the ground. Later, during the spring melt,.

Evaporation of water from the leaves of a plant gives of purified water to be evaporated. A continuous circulation of water in Earths atmospheric system. The processes in the the hydrologic cycle include: - Evaporation.

Hydrology (from Greek: ὕδωρ, hýdōr meaning water and λόγος, lógos meaning study) is the scientific study of the movement, distribution and management of water on Earth and other planets, including the water cycle, water resources and environmental watershed sustainability. Water moves into and from the various reservoirs on, over, and under the surface of the Earth, and in the process transforms into its various phases of solid (ice), liquid (water), and gas (vapor), with the total mass of water remaining fairly constant. Hydrologic Cycle The water, or hydrologic, cycle describes the pilgrimage of water as water molecules make their way from the Earth’s surface to the atmosphere and back again, in some cases to below the surface.

Now, during the water cycle , or hydrologic cycle , water can be in any one of its three states during different phases of the cycle. With no water collecting up stream, less water flows through the hydropower plant and less electricity is generated. Groundwater is an important part of this continuous cycle as water evaporates, forms clouds, and returns to earth as precipitation. The Hydrologic Cycle Surface water evaporates from by energy of the sun.

And the cycling of this water is called the hydrologic cycle, or the water cycle. The water within the hydrosphere is found in the atmosphere, as surface water, and as ground water. Water reaches land as precipitation such as rain and snow. Then the water evaporates, condenses in the atmosphere to form clouds, and falls to the earth again as precipitation, continuing the cycle.

The sun, which drives the water cycle , heats water in the oceans. Some of it evaporates as vapor into the air.
