It is the stratosphere layer of earth that protect us from harmful UV radiation. Basically ozone gas protects earth from UV radiation and nearly 90% of the ozone in atmosphere is found in the stratosphere at an altitude of 16 and 48 kilometers above the Earth's surface.
Ozone is found in a concentrated form in stratosphere only. This ozone has a tendency to absorb ultraviolet light from the Sun and protect the earth from the harmful effects of UV radiation.
Thus, it can be said that it is the stratosphere and not the troposphere that protects the Earth from UV radiation coming from the Sun
Hydropower plants capture the energy of falling water to generate electricity. A turbine converts the kinetic energy of falling water into mechanical energy. Then a generator converts the mechanical energy from the turbine into electrical energy
