Question

20 multiple choice 1 point which is the densest layer of the atomsphere? troposphere stratosphere mesosphere

Explanation:

The troposphere is the lowest layer of the atmosphere. As altitude increases, air density generally decreases. Since the troposphere is closest to the Earth's surface where gravity has the strongest pull on air molecules, it has the highest density among the given layers. The stratosphere is above the troposphere and has lower density. The mesosphere is even higher up and has lower density than the stratosphere.

Answer:

troposphere
