THE TEMPERATURE AT THE FOOT OF A MOUNTAIN IS 20°C. IF THE MOUNTAIN IS 6,000 METRES ABOVE SEA LEVEL, WHAT WILL BE THE APPROXIMATE TEMPERATURE AT THE TOP OF THE MOUNTAIN

• A. -19.0°C ✓
• B. -16.0°C
• C. 14.0°C
• D. 19.0°C

The answer to the question is: A. -19.0°C

The approximate temperature at the top of the mountain can be calculated using the environmental lapse rate, which is the decrease in temperature with an increase in altitude. The standard lapse rate is 6.5°C per 1,000 meters of elevation. Given that the foot of the mountain is at 20°C and the mountain is 6,000 meters above sea level, we can calculate the approximate temperature at the top of the mountain as follows:

Temperature difference = lapse rate * (elevation / 1,000)

Temperature at the top = Temperature at the foot – Temperature difference

Using this formula:

Temperature difference = 6.5°C / 1000m * 6000m = 39°C

Temperature at the top = 20°C – 39°C = -19°C

Therefore, the approximate temperature at the top of the mountain is -19.0°C
