What is the Meaning of Hydrosphere | Definition and What is Hydrosphere

Hydrosphere is the name given to the set of liquid parts of the Earth. It comes to the hardware system composed of water which lies below and above the surface of the planet.
The Earth's surface contains water through the degassing of the mantle (formed by rocks in solid solution with volatile substances such as water). Water from the mantle emanates by hydrothermal processes and the action of volcanoes. At the top level of the atmosphere, moreover, solar radiation generates the photolysis of water, which breaks its molecules and hydrogen.
The process of change of State and transport of water form what is called the water cycle or hydrological cycle. The Earth has the distinction of being the only planet in the solar system that has water in its liquid state on a permanent basis. in fact, 71% of the Earth's surface, is covered by liquid water.
Hydrosphere, therefore, has water in different States since apart from oceans, rivers and lakes, it contains water in glaciers, clouds in the atmosphere, groundwater sources and even in the biosphere (humans, animals and plants).
It is estimated that there are nearly 1.34 billion km3 of water on Earth. More than 97% is in the oceans while a little more than 2% appears in the polar ice caps. The rest of the water is divided between aquifers, lakes, inland seas, soil moisture, air and rivers.
