Importance of Earth's hydrosphere

Introduction:
     As far as we know , the earth we live on is the only planet that is able to support life. among other factors, earth is just the right distance from the sun to have temperatures that are suitable for life to exist. also, the earth's atmosphere has exactly the right type of gases in the right amounts for life to survive. Our planet also has water on its surface, which is something very unique. in fact,earth is often called the''BLUE PLANET'' because most of it is covered in water. this water is made up fresh water in rivers and lakes, the saltwater of the oceans and the estuaries,groundwater and water vapor. together,all these water bodies are called HYDROSPHERE.

 

INTERACTIONS OF THE EARTH'S HYDROSPHERE:
     It is important to realize that the hydrosphere interacts with other global system, including the atmosphere, lithosphere and biosphere.


    * ATMOSPHERE when 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 rain or snow.

    *LITHOSPHERE in the lithosphere( the ocean and continental crust at the earth's surface), water is an important weathering agent , which means that it helps to break rock down into fragments and then soil, these fragments may be transported by water to another place , where they are deposited. this is called''EROSION

    *BIOSPHERE in the biosphere, land plants absorb water through their roots and then transport this through their vascular system to stems and leaves. this water is needed in photosynthesis.

THE IMPORTANCE OF EARTH'S HYDROSPHERE
      it is so easy sometimes to take our hydrosphere for granted and we seldom take the time to really think about the role that is part of the planet plays in keeping us alive.these are the some importance of hydrosphere as what i understand about hydrosphere...

  WATER IS A PART OF LIVING CELLS that each cells are living organisms is made up almost 75% of water and this allow the cells to function normally. and most of the chemical reactions are occur in life,
  WATER PROVIDES A HABITAT. the hydrosphere provides an important place for many animals and plants to live.
  REGULATING CLIMATES one of water's unique characteristic is its high specific heat. this means that water takes a long time to to heat up and also a long time to cool down. this is important in helping to regulate temperatures on earth so that they stay within a range that is acceptable for life exist.
  HUMAN NEEDS humans use water in a number ways. drinking water is obviously very important, but water is also used domestically in washing and cleaning and in industry also. water can also be used to generate electricity through hydro power.

 these are just a few of the very important functions that water plays in our planet. many of the functions of water relate to its chemistry and to the way in which it is able to dissolve substance in it.. and the earth's hydrosphere is important to us.
