Question

What is the relationship between temperature and altitude in the stratosphere? As altitude increases, temperature decreases. As altitude increases, temperature increases. As altitude increases, temperatures remain the same. As altitude increases, temperatures vary.

Answer 1

Answer:

Option (2)

Explanation:

The stratosphere is the layer above the troposphere that ranges from a height of about 10 to 50 km from the ground surface. This layer covers about 15-20% of the total atmospheric mass of earth. In this layer, as the height increases, the temperature also starts increasing. This increase in temperature is because of the presence of the ozone layer (O³) that absorbs the UV radiations emitted from the sun. These radiations are harmful to living organisms as they can cause various types of diseases.

Hence, the correct answer is option (2).
