Final answer:
To estimate the temperature at the Mt. Everest Camp situated at 6000 meters, using the average adiabatic lapse rate of 9.8°C/1000m, the drop in temperature from Pokhara's 20°C is approximately 49.98°C. Therefore, the temperature at Mt. Everest Camp is about -30°C.
Step-by-step explanation:
To determine the temperature at Mt. Everest Camp at an altitude of 6000 meters, if Pokhara has a temperature of 20 degrees Celsius at an altitude of 900 meters, you can use the dry adiabatic lapse rate, which is typically around 9.8 degrees Celsius per 1000 meters. According to this rate, temperature decreases as altitude increases. Since no specific lapse rate is provided in the question, we will use the average dry adiabatic lapse rate for our calculation.
To calculate the expected drop in temperature, we take the difference in altitude (6000 m - 900 m = 5100 m) and divide by 1000 to convert meters into kilometers (5100 m / 1000 m/km = 5.1 km). Then we multiply this difference in kilometers by the average lapse rate (5.1 km * 9.8°C/km = 49.98°C). Finally, we subtract this value from the temperature at Pokhara to estimate the temperature at the Everest Camp (20°C - 49.98°C ≈ -30°C). Therefore, the estimated temperature at the Everest Camp at an altitude of 6000 meters would be approximately -30 degrees Celsius.
