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 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.
