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: -Answer is (d) the axis of rotation of the earth is tilted with respect to the plane of its orbit. Explanation: Axis of rotation of the earth is not perpendicular to the plane of its orbit. The tilt is responsible for the change of seasons on earth.
Detailed explanation-3: -Remind students that the two reasons seasons occur are the tilt of a planet’s axis and its orbit around the sun.
Detailed explanation-4: -The Earth rotates on its own axis and it is tilted at an angle of 23.5° with respect to its orbital plane; this causes the occurrence of seasons. The revolution of the Earth around the Sun, which requires 365 days and 6 hours, in an elliptical orbit also causes the change in seasons.
