Answer:
In summer season, sun would not set at latitude 66.5 N and above. In summer season for southern hemisphere, sun would not set for latitude 66.5 S and above.
Explanation:
Season on Earth occurs due to the inclination of the axis about which it rotates. Due to this, there is different length of day and night in different hemispheres at a time.
Sun is highest in the sky in northern hemisphere in summers. So the places at 66.5 N and higher latitude experience 24 hours sun light.
Similarly, in northern hemisphere summers, places at 66.5 S and higher latitude experience 24 hours sun light.
