Question

The part of atmosphere which contains constant gases with known composition called :

• A. Homosphere
• B. Thermosphere
• C. Heterosphere
• D. None of these

Answer 1

Answer: (A)

Homosphere

The part of the atmosphere which contains constant gases with a known composition called homo-sphere.

The homosphere is the lower of the two and the location in which turbulent mixing dominates the molecular diffusion of gases. In this region, which occurs below 100 km (about 60 miles) or so, the composition of the atmosphere tends to be independent of height.
