The ultraviolet radiations are damaging to living components of the environment. Give a reason.
When UV (ultraviolet) radiations from the sun reach earth’s atmosphere which is heavily rich in oxygen. These high energy UV rays split molecular oxygen (O2) into free oxygen (O). Afterward, this free oxygen reacts with molecular oxygen; it forms ozone (O3).
These harmful UV radiations of the sun, can cause skin cancer in human and can cause many health hazards like skin cancer, cataract, destruction of plants, etc.
