What is hydrologic.
The hydrologic -- or water -- cycle is the continuous movement of water between the earth and the atmosphere. 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. When water falls to the ground it can ...

Climate Change and the Hydrologic Cycle. As climate changes, so too does the movement of water through land, oceans, and atmosphere.

It is a function of the climate and includes the phenomena by which water first occurs as atmospheric water vapor, passes into a liquid or solid form, falls as precipitation, moves along or into the ground surface, and returns to the atmosphere as vapor by means of evaporation and transpiration.Description of the Hydrologic Cycle This is an education module about the movement of water on the planet Earth.

Why are water cycle processes important? 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.

Key Points On average, shallow groundwater wells required a storm of 31 mm or greater to respondWith more than 70% of Earth's surface covered in water, water is one of the planet's most abundant natural resources. Thanks to the natural hydrologic cycle (water cycle), water on Earth is continuously recycled.

Evapotranspiration. The next component of the hydrological cycle is evapotranspiration which is a combination of evaporation of water with evaporation originating from plants. Condensation. The next component is condensation, or the formation of lots of water, dew, snow or ice.Hydro-geomorphology is science that deals with occurrences of water with respect to landform.

Water resource managers use GIS technology to visualize and analyze topographic, hydrographic, and hydrologic data for tasks such as assessing water quality, estimating water availability, planning flood prevention, understanding the natural environment, and managing water resources.
The hydrologic cycle happens continuously, with all different steps happening simultaneously around the world. The biggest concern that many have with the hydrologic cycle is the availability of drinkable water, which is something that is constantly in flux, and the melting of the huge ice storage sheets at the polar caps.
