alleryThe environmental lapse rate describes how, in the troposphere, temperature:
Arises by about 0.6°C for every 100 m of ascent
Bfalls by about 0.6°C for every 100 m of ascent
Cfalls by about 6°C for every 100 m of ascent
Dstays constant regardless of the altitude
Answer & Solution
Correct answer: B. falls by about 0.6°C for every 100 m of ascent
1. Within the troposphere, temperature falls as altitude increases.
2. The rate of that fall is roughly 0.6°C for every 100 m climbed.
3. That figure is what the environmental lapse rate names.
4. It is a decrease, so any option describing a rise has the direction backwards.
5. In the stratosphere above, the pattern reverses and temperature increases with height.
