How many kilometers above sea level would this mountain reach, and what would the approximate temperature be at this altitude?
UkoKoshka [18]

Answer:

It would be about 9 kilometers above sea level, and you can expect the temperature to be cold. (see explanation)

Explanation:

If there's no snow or rain and you’re not in a cloud, then the temperature decreases by about 5.4°F for every 1,000 feet up you go in elevation. That is 9.8°C per 1,000 meters. However, if you’re in a cloud, or it is snowing/raining, the temperature decreases by about 3.3°F for every 1,000 feet up you go in elevation. Thus meaning it’s a change of 6°C per 1,000 meters.
