The radiation given off by the sun is electromagnetic waves. The waves are made up of two types of rays ultraviolet and infrared.
In fact, radiations are reflected by earth but not emitted.
The vast majority of energy on earth comes from the sun. The remainder is received through solar flares or radiations from other stars.
Generically the atmosphere absorbs portions of the Sun's radiation. In particular the Ozone layer absorbs a lot of UV radiations and of course water in the atmosphere (clouds) can blot out the Sun entirely.
Uranium-238 emits alpha radiation; its half-life is 4,468×109 year.
Intensity of insolation refers to the intensity of the sun's rays on the earth's surface. It is a measure of solar energy that is received by a given surface area at a given time.
Ozone layer protects us from the harmful UV radiations of the sun. It filters out these harmful radiations. It is present in stratosphere.

Ozone layer protects us from the harmful UV radiations of the sun. It filters out these harmful radiations. It is present in stratosphere.
Ozone layer protects us from the harmful UV radiations of the sun. It filters out these harmful radiations. It is present in stratosphere.
The role of ozone layer is to block the harmful UV radiations from the sun. These are fatal rays for life on earth.
If it is sun glasses than we use it to save our eyes from the radiations of sun.
Uv radiations are the radiations released from the sun. These radiations are fatal for life. Ozone layer protects us.

Ozone layer protects us from the harmful UV radiations of the sun. It filters out these harmful radiations. It is present in stratosphere.
Ozone layer protects the earth from the harmful ultra violet radiations of the sun. It is present in the stratosphere region of the atmosphere.
Ozone layer protects the earth from the dangerous ultra violet radiations of the sun. It is present in the stratosphere region of the atmosphere.
Ozone filters out UV-B radiations only. These are the highest frequency radiations of sun.
