Introduction:
The rotation of the earth around the sun is in an elliptical path. The Earth axis is not perpendicular to this plane of ellipse and is tilted at an angle of 23o. This results in changes in daylight, temperature and seasons in different parts around the earth. Summer season occurs when the Northern Hemisphere of the earth is tilted fully towards the sun.
Answer to Problem 1SA
Correct Answer:
The Northern Hemisphere of the earth is tilted mostly towards the sun in the summer season. Hence, correct answer is option b.
Explanation of Solution
Reasons for correct answer:
Summer season is a result of the tilted Northern Hemisphere mostly towards the sun. This makes the Northern Hemisphere to receive more sunlight, and increase in day light. In June, the Northern Hemisphere tilts towards the sun, receiving direct sunlight, resulting in more daylight than the Southern Hemisphere, which is away from the sun.
Hence, option b is correct.
Reasons for incorrect answer:
Option a. is given as, “spring.”
The Northern Hemisphere of the earth is tilted mostly towards the sun in the summer season not in spring. Hence, option a. is incorrect.
Option c. is given as “autumn”
Spring and autumn are results of moving of Northern Hemisphere away from the sun, but not completely towards the sun. Seasonal variations occur due to the tilting of the earth, rotation of the earth and its revolution around the sun. Spring and autumn do not result when Northern Hemisphere tilts mostly towards the sun. Hence option c. is incorrect.
Option d. is given as “winter”
When the Northern Hemisphere experiences winter, it will be tilted away from the sun, but not near. So option d is incorrect.
Hence options a., c., and d. are incorrect
Summer season occurs in the Northern Hemisphere due to its maximum tilting towards the sun. Thus, correct option is b.
