SECTION D: Higher Order Thinking Skills (HOTS – 3 marks each)
- If Earth stopped rotating, what would happen to life and climate on Earth?
- Suppose the Earth had no tilt. How would it affect seasons and day-night patterns?
- Explain why solar eclipses do not happen every month even though the Moon orbits the Earth monthly.
- Why can the small Moon block the huge Sun during a solar eclipse?
- How would life be affected if the Earth took 500 days instead of 365 days to complete a revolution?

Solution Sheet
Section A – MCQs:
- (b) Rotation
- (c) 23.5°
- (a) Earth
- (c) West to East
- (b) Solar eclipse
- (b) 21 June
- (c) Seasons
- (b) Pole Star
- (b) Southern Hemisphere
- (b) Orbit
Section B – One-Mark Answers:
11. A day when day and night are equal in length.
12. Sun’s apparent movement from East to West.
13. About 27 days.
14. Size as perceived from a certain distance.
15. The North Pole or South Pole depending on tilt.
16. 365 days and 6 hours.
17. Tilted axis and revolution.
18. Lunar eclipse.
19. Do not look at the Sun directly; use proper filters.
20. It reflects sunlight.
Section C – Two-Mark Answers:
21. Rotation is Earth spinning on its axis (causes day/night); revolution is Earth moving around the Sun (causes seasons).
22. Because Earth’s position changes during revolution, changing our view of the night sky.
23. The tilt causes one hemisphere to receive more/less sunlight, changing day length.
24. The Moon’s shadow falls only on a small region during a solar eclipse.
25. As Earth rotates, parts face the Sun (day), and others face away (night).
26. It marks the northernmost latitude where the Sun can be overhead.
27. Total eclipse – Moon fully covered; partial – Moon partially covered.
28. Because Earth rotates from West to East.
29. When it is summer in one, it is winter in the other due to tilt.
30. Solstices are days with longest/shortest day; 21 June and 22 December.
Section D – HOTS Answers:
31. Permanent day/night on each side of Earth; climate would become extreme.
32. No seasons would occur; day and night would remain the same throughout the year.
33. The Moon’s orbit is tilted, so alignment doesn’t occur every month.
34. Due to its closeness to Earth, the Moon’s apparent size matches the Sun.
35. Seasons would last longer; climate cycles would shift; agriculture and ecology would be affected.
