Question

What is thinner atmosphere?​

Answer 1

Answer:

The Earth's atmosphere is considered relatively thin, and it gets thinner further away from the planet's surface. Thin atmospheres are characterized by their relative lack of hydrogen. Mars' atmosphere mostly consists of carbon dioxide and is not conducive for life.

Answer 2

Answer:

The atmosphere—air—is much thinner at high altitudes. There is no atmosphere in space. Scientists say many of the gases in our atmosphere were ejected into the air by early volcanoes. At that time, there would have been little or no free oxygen surrounding the Earth.
