Hydrosphere’s Abilities

           Earth is the only planet that man can live. Earth has the right distance from the sun atmosphere that has exactly the right type of gasses for life to survive. According to my research earth is often called the "Blue Planet" because most of it is covered in water. Rivers and lakes are made up of freshwater, oceans is made up of saltwater. All these water bodies are called the hydrosphere. 

          According to my research, hydrosphere is the liquid water component of the Earth. It includes the oceans, seas, lakes, ponds, rivers and streams. The hydrosphere covers about 70% of the surface of the Earth and is the home for many plants and animals.The hydrosphere, like the atmosphere, is always in motion. The motion of rivers and streams can be easily seen, while the motion of the water within lakes and ponds is less obvious. Some of the motion of the oceans and seas can be easily seen while the large scale motions that move water great distances such as between the tropics and poles or between continents are more difficult to see. These types of motions are in the form of currents that move the warm waters in the tropics toward the poles, and colder water from the polar regions toward the tropics. These currents exist on the surface of the ocean and at great depths in the ocean (up to about 4km).

              

           Base on my research hydrosphere interacts with other global systems, including the atmosphere, lithosphere and biosphere.

    * Atmosphere

      When water is heated (e.g. by energy from the sun), it evaporates and forms water vapour. When water vapour 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.

     

    * 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 rock fragments and then soil. These fragments may then be transported by water to another place, where they are deposited. This is called erosion. These two process, i.e. weathering and erosion, help to shape the earth's surface. You can see this for example in rivers. In the upper streams, rocks are eroded and sediments are transported down the river and deposited on the wide flood plains lower down. On a bigger scale, river valleys in mountains have been carved out by the action of water, and cliffs and caves on rocky beach coastlines are also the result of weathering and erosion by water.

     

    * Biosphere

      In the biosphere, land plants absorb water through their roots and then transport this through their vascular (transport) system to stems and leaves. This water is needed in photosynthesis, the food production process in plants. Transpiration (evaporation of water from the leaf surface) then returns water back to the atmosphere.

                   Hydrosphere is  important because it's a major source for water and food. We also need it to further our transportation, which is the ships traveling across oceans. Also it has a lot of life in it which is a major food source for us. People that live on beaches and coastlines rely heavily on fishing to support their families. Without the hydrosphere we wouldn't have any water and we wouldn't survive. Thank goodness we have a hydrosphere.
