Question

How is the size of a planet related to the thickness of its atmosphere? Explain.

Answer 1

Explanation:

The thickness of a planet's atmosphere depends on the planet's gravity and the temperature of the atmosphere. A planet with weaker gravity does not have as strong a hold on the molecules that make up its atmosphere as a planet with stronger gravity. The gas molecules will be more likely to escape the planet's gravity.
