P5 General Studies: Earth, Sun and Moon, Day, Night and Seasons (Paper 4: mistake clinic)
Paper four drills the usual mix ups, keeping causes and figures in separate boxes.
Direct answers Remember one line: rotation runs the day, the orbit runs the year, the tilt runs the seasons.

03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | Rotation | One turn is one day, so rotation causes day and night. |
| 2 | 24 hours | One turn is 24 hours, which is one day. |
| 3 | Darkness | The side facing away gets no sunlight, so it is night there. |
| 4 | 90 degrees | 15 times 6 gives 90 degrees. |
| 5 | About 30.4 days | 365 divided by 12 gives 30.4 days. |
| 6 | 366 days | 365 plus 1 gives 366 days. |
| 7 | 7 am | 15 minus 8 gives 7 am. |
| 8 | 54.6 days | 27.3 times 2 gives 54.6 days. |
| 9 | It causes the seasons by changing the Sun angle and daylight through the year | The tilt changes the angle of sunlight through the year, which gives the seasons. |
| 10 | The main cause is the 23.5 degree tilt changing the Sun angle and daylight | Earth is closest to the Sun during the northern winter, so distance is not the main cause. |
04 What to do after marking
- After marking, redo only the wrong items and write down which step went wrong (formula, unit, or misread number).
- Repeat the same item two days later; move to the next paper only when both attempts are correct.
- Parents only need the answer and note columns; there is no need to explain every item.
With all four done, go back to the chapter page and revise rotation against orbit.Tutor Registration →
