Importance of Hydrological Cycle or Water Cycle
The hydrological cycle commonly referred to as the "water cycle," is Earth's typical system for recycling water. It is a natural cycle through which water flows from the land's surface or oceans to the sky and falls as precipitation. The cycle refers to the continuous water circulation between life, the oceans, and the subsurface. The evaporation of water from the ocean's surface kicks off the hydrologic cycle.
- The oceans contain around 71% of the water on the globe.
- The remaining freshwater is stored in glaciers, ice caps, lakes, groundwater sources, the atmosphere, streams, and living things.
- The amount of water evaporating off the land's surface and returning to the atmosphere is about 59%.
- The remaining surface runoff either seeps into the earth or partially turns into glaciers.
What is a hydrological cycle?
The hydrological cycle is the entire process by which water moves from the land and ocean surface to the sky and then back again as precipitation.
