Atmosphere is classified into different zones, which of the following is not among this classification?

  1. Ionosphere

  2. Ozonosphere

  3. Lithosphere

  4. None of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In the given options, ionosphere and ozonosphere are included in atmosphere.  Ionosphere consists of ions due to ultra violet radiations causing photo ionization and hence forming ionosphere. Ozonosphere is also called as stratosphere which consists of ozone gases that prevents UV rays from entering the earth’s surface. On the other hand lithosphere is not a layer of atmosphere but it is a hard surface consisting of rocks on earths surface.

Which of the following layers of atmosphere absorb UV light radiations?

  1. Ionosphere

  2. Ozonosphere

  3. Troposphere

  4. None of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Layer of atmosphere which absorbs UV light radiations is known as ozonosphere. It is a region of Earth's stratosphere. This region contains high concentrations of ozone in comparison to other parts of the atmosphere. Ozonosphere is mainly found in the lower portion of the stratosphere. This layer protects earth from harmful UV light radiations.
