Which upper boundary of the thermosphere is considered before the exosphere begins?
Answer and explanation
Correct answer: Thermopause
Option C is correct. The thermopause is commonly treated as the upper boundary or transition region of the thermosphere, above which the exosphere begins. The tropopause separates the troposphere from the stratosphere, the stratopause is the upper boundary of the stratosphere, and the mesopause separates the mesosphere from the thermosphere. Thus, the prefix in thermopause directly identifies its relation to the thermosphere.
