Question

In mesosphere, the temperature

• A. Rises from - $2^0$ to ${15}^0$ C
• B. Rises from - $2^0$ to ${92}^0$ C
• C. Decreases from - $2^0$ to - ${15}^0$ C
• D. Decreases from - $2^0$ to - ${92}^0$ C

Answer 1

The correct option is D Decreases from - $2^0$ to - ${92}^0$ C

Temperatures in the mesosphere decrease with altitude. Because there are few gas molecules in the mesosphere to absorb the Sun’s radiation, the heat source is the stratosphere below. The mesosphere is extremely cold, especially at its top, about -90 degree Celsius. So the correct answer is ' it decreases from -2 to -92 degrees. '
