<span>Geologists generally know the age of a rock by determining the age of the group of rocks, or formation, that it is found in. The age of formations is marked on a geologic calendar known as the geologic time scale. Development of the geologic time scale and dating of formations and rocks relies upon two fundamentally different ways of telling time: relative and absolute.</span>

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.
