At 2000 feet altitude, standard temperature lapse is approximately how many degrees Celsius lower than sea level?

Explanation:
In the International Standard Atmosphere, the air cools by about 2°C for every 1,000 feet of altitude. So at 2,000 feet, the temperature is roughly 4°C lower than sea level. That means the temperature difference is 4°C (a drop of 4 degrees), which matches the answer choice. In context, the exact sea-level temperature can vary, but the standard lapse rate used for these calculations is approximately 2°C per 1,000 ft up to high altitudes.
