Question

1. the two properties that change with altitude are and .

Explanation:

In the context of atmospheric science (a subfield of Natural Science, specifically related to Physics and Geography), as altitude increases, air pressure (atmospheric pressure) decreases because there is less air above to exert force. Also, temperature often changes with altitude (in the troposphere, temperature generally decreases with increasing altitude, while in the stratosphere, it can increase due to ozone absorption of UV radiation). These are two key properties that vary with altitude.

Answer:

air pressure and temperature
