Question

The _______ is the coldest layer of the atmosphere.

a. troposphere
b. stratosphere
c. mesosphere
d. thermosphere

Answer 1

Troposphere, stratosphere, mesosphere and thermosphere are the four layers of the atmosphere

The mesosphere is the coldest layer of the atmosphere. Correct answer: C

The emsosphere extends upward to a height of about 85 km (53 miles) above our planet. This layer is characterized with too thin air to breath and air pressure at the bottom of the layer which is well below 1% of the pressure at sea level.

Answer 2

The correct answer is Mesosphere, and more specifically the region where Mesophere becomes Thermosphere (Thermosphere itself is pretty warm, ,with temperatures up to 2000 degrees!)/ This region is Mesopause: so an even better answer than Mesosphere is Mesopause
