The correct answer is: A. Decreases with increasing height.
The stratosphere is the second layer of Earth’s atmosphere, above the troposphere and below the mesosphere. It extends from about 10 to 50 kilometers (6 to 31 miles) above Earth’s surface. The stratosphere is characterized by an increase in temperature with increasing altitude. This is due to the presence of ozone, which absorbs ultraviolet radiation from the sun. The ozone layer is located in the stratosphere, and it helps to protect life on Earth from the harmful effects of ultraviolet radiation.
Option B is incorrect because the temperature in the stratosphere decreases with increasing height.
Option C is incorrect because the temperature in the stratosphere does not both increase and decrease depending on the season.
Option D is incorrect because the temperature in the stratosphere can be measured.
