The Importance of Earth`s Hydrosphere

              Earth`s  Hydrosphere is important not just in human but also in nature and other things here on earth in the lithosphere it is important agent in weathering that it helps to break rock down into rock fragments and then soil. These fragments may then be transported by water to another place, where they are deposited  this process is called erosion . Then, in the atmosphere , when water is heated, it evaporates and forms water vapor. When water vapor cools again, it condenses to form liquid water which eventually returns to the surface by precipitation e.g. rain or snow. This cycle of water moving through the atmosphere and the energy changes that accompany it, is what drives weather patterns on earth. and then in the Biosphere, land plants absorb water through their roots and then transport this through their vascular system to stems and leaves, water is needed in photosynthesis, the food production process in plants
             Humans use water in a number of ways. Drinking water is obviously very important, but water is also used domestically (e.g. washing and cleaning) and in industry. Water can also be used to generate electricity through hydro power. The derivation of the term hydrosphere, from the Greek words for water and ball, is truly descriptive of our world, as it reflects the abundance and importance of water on Earth.
On Earth, water exists in the three primary states of matter; liquid, solid, and gas. The distance of Earth from the Sun, by fortunate coincidence.n physical geography, the term hydrosphere (Greek hydro means "water") describes the collective mass of water found on, under, and over a planet's surface. The Earth's hydrosphere consists chiefly of the oceans, but technically includes clouds, inland seas, lakes, rivers, and underground waters. Hydrosphere refers to that portion of Earth that is composed of water. Still, despite the significance of water, we often take it for granted. Water conservation only comes to our mind in times of crisis and dry seasons. we should take care of our earth because it is only planet where life exist..
