Answer: B. The Sun’s rays hit the Earth more directly in summer

Explanation: In summer, the Sun’s rays hit the Earth at a more direct angle, which means they are concentrated over a smaller area and therefore impart more heat, making it warmer.

Answer: B. March 21

Explanation: March 21 is commonly referred to as the spring equinox in the Northern Hemisphere, marking the start of spring when day and night are approximately equal in length.

Answer: C. It determines which hemisphere receives more sunlight

Explanation: The earth’s spin axis is tilted with respect to its orbital plane. This is what causes the seasons. When the earth’s axis points towards the sun, it is summer for that hemisphere.
