Answer:
Around -20c and 15c
Explanation:
The 3-7 km region of the earth's surface is almost oxygen-free, air is thin (little oxygen gas; air molecules are too far apart), temperatures are around -20c to -15c . The gas that is predominant is nitrogen. Due to temperaature, the ability of living beings to exist at this distance is low, since the environment is unheard of.
