Question

13 Where is the ozone layer found?

• A. troposphere
• B. thermosphere
• C. exosphere
• D. stratosphere

Answer 1

The correct option is D

stratosphere

The explanation for the correct option:

(D)-Stratosphere

• The stratosphere extends from the top of the troposphere to about 50 kilometers (31 miles) above the ground.
• An ozone layer exists in the stratosphere.
• This layer's ozone molecules absorb and alter the Sun's high-energy ultraviolet (UV) light.

The explanation for the correct options:

(A)-Troposphere

• The troposphere is the atmosphere's lowest layer.
• It is the layer where we reside.
• The wind moves take place in the layer. It also contains water vapour, which is what causes clouds.
• This is the layer in which weather changes occur.

(B)-Thermosphere

• The thermosphere is the fourth layer of the Earth's atmosphere, which absorbs the sun's rays and heats up rapidly.
• The thermosphere is where satellites orbit the Earth and where the auroras, a brilliant light show created by colliding particles, occur.
• The thermosphere is an extremely active layer.

(C)-Exosphere

• The exosphere is the atmosphere's outermost layer.
• Light gases including hydrogen, carbon dioxide, atomic oxygen, and helium make up the majority of the exosphere.
• All of the gases mentioned above are so light that they can elude the gravitational magnetic attraction of the Earth and scatter freely throughout space.

Final answer: A correct answer is an option (D)
