Question

On a particular day, Denali had a temperature of -23°c at its peak and 13°c at its base. what could be the reason for this temperature difference?
A. temperature increases with an increase in altitude.
B. temperature decreases with an increase in altitude.
C. the base is cold to the gulf of Alaska.
D. the mountain receives lake-effect snow.

Answer 1

Answer:

Option D, the mountain receives lake-effect snow.

Explanation:

Mount McKinley is the center of Denali and it is also the part of Alaskan Range of mountain peaks  which is surrounded by low lands. This mountain has extreme weather variations which is entirely different from the areas of south central Alaska.

However the lake at the base reduces the rate of increase of temperature at the base of Denali. It is so because the angle at which the lake water contacts the Denali mountain , decreases the  increase in temperature.

Hence, option D is correct
