Question

In Alaska during January, what temperature difference can be observed between ground level and several meters below ground?

a) 0°C
b) 45°C
c) 30°C
d) 50°C

Answer 1

In Alaska during January, there can be a significant temperature difference between ground level and several meters below ground due to the insulating effect of the snow cover.

Step-by-step explanation:

In Alaska during January, there can be a significant temperature difference between ground level and several meters below ground. This temperature difference is due to the insulating effect of the snow cover on the ground. Snow acts as an insulator, preventing heat from escaping the ground and maintaining a relatively higher temperature below the surface.

For example: The air temperature above the ground might be -20°C, but a few meters below the surface, the temperature might only be -5°C. This is because the snow cover traps the heat from the ground, creating a warmer microclimate.

Therefore, the correct answer is d) 50°C.
