Question

What is normal lapse rate?

• A. For every 165 metre rise in altitude, the temperature decreases by 2 degree Celsius.
• B. For every 162 metre rise in altitude, the temperature decreases by 1 degree Celsius.
• C. For every 160 metre rise in altitude, the temperature decreases by 1 degree Celsius.
• D. For every 165 metre rise in altitude, the temperature decreases by 1 degree Celsius.

Answer 1

Answer: (D)

The lapse rate is the rate at which an atmospheric variable, normally temperature, in Earth's atmosphere, falls with altitude. For every 165 meters rise in altitude, the temperature decreases by 1 degree Celsius. This is called the normal lapse rate.
