Question

Sunlight is present for only a short span of time in
A)Polar region
B)Subtropical region
C)Desert region
D)Himalayan region

Answer 1

Hint: The earth rotates on its axis and revolves around the sun. The places facing towards the sun experience day and the once away experience night. The earth’s axis is not straight so there are few regions which experience sunlight for a very short span.

Complete answer:
The earth rotates around its axis. The axis of the earth is tilted at an angle of 23 degree. The tilt of the earth is responsible for the daylight hours. The daylight hours are maximum at the equator. As we move away from the equator, the daylight hours decrease.
The equatorial region experiences the maximum period of sunlight.

The polar region is located at very higher latitudes i.e., around 90 degrees at each hemisphere. This place is farthest from the equator and receives bare minimum sunlight.

Also, the tilt of the earth makes it very difficult to reach the poles. Thus, the polar region experiences winters throughout, covered with snow and receives very less sunlight.
Desert Region- Desert is the arid land. It receives very little rainfall and the living conditions are very hostile. Most of the desert is located in the tropical regions.
Himalayan region- Himalayas are the highest mountain range in the world which is covered with snow. It receives sunlight.

Hence, the correct answer is option (A)

Note: The areas above the arctic circle receive 24 hours of sunlight in summer and 24 hours of darkness during winters. The sun can even be seen at midnight. The arctic region experiences 6 months of day continuous six months of night.
