what is natural environment - lithosphere, hydrosphere, atmosphere and biosphere.

We know about the lithosphere, hydrosphere, atmosphere and biosphere. These are the spheres that work as a natural safeguard. The lithosphere is the solid crust or the hard top layer of the earth. The lithosphere is made up of some solids like rocks and minerals. The lithosphere provides for all human activity like agriculture. All landforms are called as lithosphere; the lithosphere means our land life living places and some beautiful places which are forests. Forests are giving many things to human that are invisible but human beings are enjoying their life with the help of forests. We are living on the earth with the support of forests.  

           Hydrosphere means the domain of water. Water is from various sources like seas, rivers, lakes and oceans. We know that water is essential for mankind. But we cannot think about water. Just think water, air and electricity are not for any one person it is common for all human beings. There are no restrictions for countries and also for the hydrosphere because air and water are common to all human beings on this earth. Man cannot understand or realize these facts, but it is simply quite natural.

  

  

      The atmosphere is the thin layer of air that surrounds the earth. The atmosphere is protecting us from harmful rays. Sun radiates many rays like ultraviolet rays UV rays affect skin cancer in humans. But the atmosphere is protected from the rays atmosphere is also has many spheres. Ozone layers are filtered UV rays and protect human beings from harmful ones. The gravitational force of the earth holds the atmosphere around it. We know that the biosphere protects human beings. This helps us to live with humans naturally. If we don’t like to live in a natural way ozone layer holes develop. This world is made up of nature but human activity is changing the entire world. We should come back to nature otherwise future world can have nothing to live.
