Averaged over the summer months, even though there are more hours of daylight at the Arctic Circle (66 ½°) compared to at 40° latitude, there is a lower maximum daily temperature at the Arctic Circle (66 ½°) compared to at 40°. This is because (choose all correct statements):

A. At the Arctic Circle, the sun's rays travel through a thicker layer of atmosphere, reducing the amount of solar energy reaching the ground. B. The increased cloud cover at the Arctic Circle during the summer reduces the amount of solar energy reaching the ground. C. At the Arctic Circle, solar energy reaching the ground is spread over a smaller area, reducing the intensity of solar energy reaching the ground. D. At the Arctic Circle, the daytime position of the sun in the sky is lower (closer to the horizon), reducing the intensity of solar energy reaching the ground.

A. At the Arctic Circle, the sun's rays travel through a thicker layer of atmosphere, reducing the amount of solar energy reaching the ground.

C. At the Arctic Circle, solar energy reaching the ground is spread over a smaller area, reducing the intensity of solar energy reaching the ground.

D. At the Arctic Circle, the daytime position of the sun in the sky is lower (closer to the horizon), reducing the intensity of solar energy reaching the ground.

Explanation:

The arctic circle is the northernmost part of the world and is defined by the latitude of 66° 33' N the temperature of the warmest months in July and is below 10 ° C and thus has cool and cold summers. Thus rays of the sun have to enter or travel through the thick layers of the atmosphere being at a height altitude and less sunlight is received at the poles and hence the small area gets insolation. Thus the day time position of the sun in lower latitudes of 40 to 60 degrees than it's in after noon time is more intense.
