Explanation:
Detailed explanation-1: -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. When the earth’s axis points away, winter can be expected.
Detailed explanation-2: -Remind students that the two reasons seasons occur are the tilt of a planet’s axis and its orbit around the sun.
Detailed explanation-3: -But Earth’s distance from the sun doesn’t change enough to cause seasonal differences. Instead, our seasons change because Earth tilts on its axis, and the angle of tilt causes the Northern and Southern Hemispheres to trade places throughout the year in receiving the sun’s light and warmth most directly.
