What is homosphere and heterosphere?
Answers
Answer:
Homosphere & Heterosphere. ... Heterosphere is the upper portion of a two-part division of the atmosphere according to the general homogeneity of atmospheric composition; the layer above the homosphere. The hetero-sphere is characterized by variation in the composition and the mean molecular weight of constituent gases.
Answer:
Explanation:
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.
The heterosphere is the upper portion of the Earth's atmosphere, in which gases are fractionated according to their molecular weight. It lies above the homosphere, where chemical constituents are well mixed. On average the heterosphere begins at an altitude of about 80 km.
