Question

The tropopause is best described as which of the following?

Answer 1

The tropopause is the transition layer between the troposphere and the stratosphere in Earth's atmosphere. It is located at an altitude of about 12-15 km, and it is the coldest part of the atmosphere.

Step-by-step explanation:

The tropopause can be defined as the transition layer between the troposphere and the stratosphere in Earth's atmosphere. It is located at an altitude of about 12-15 km (7-8 miles), and it is the coldest part of the atmosphere. The temperature in the troposphere decreases steadily with increasing altitude, but at the tropopause, the temperature starts warming again due to the absorption of UV radiation by ozone in the stratosphere.

Answer 2

The lowest layer of Earth's atmosphere is called troposphere.The layer immediately next to troposphere is called Stratosphere. The boundary layer between troposphere and stratosphere is described as tropopause.
