S1 Geography: Map Reading and Scale (Paper 1: basics)
S1 Geography map reading paper one, basics: ten questions on scale conversion, grid references and what contour spacing tells you, with every figure checked between centimetres and metres.
Direct answers Answers in order: 200 m, 1 000 m, easting then northing, 1 600 m, a steep slope, 1 000 m, 0.24 square kilometres, twice, 600 m, and both sides of the ratio share one unit.

03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | 200 metres. | Dividing 20 000 cm by 100 gives 200 m, since both sides of the ratio use the same unit. |
| 2 | 1 000 m, that is 1 km. | Each centimetre stands for 200 m, so five centimetres give five times 200 m. |
| 3 | The first three are the easting and the last three the northing. | Grid references are always read easting first and northing second. |
| 4 | 1 600 m, that is 1.6 km. | At 1:50 000 one centimetre stands for 500 m, and 3.2 times 500 gives 1 600 m. |
| 5 | A steep slope with a large gradient. | The closer the contours, the greater the height change over the same horizontal distance. |
| 6 | 1 000 m, that is 1 km. | At 1:25 000 a centimetre stands for 250 m, so four centimetres make 1 km. |
| 7 | 0.24 square kilometres. | Convert to 400 m by 600 m first, which gives 240 000 square metres. |
| 8 | Twice as long. | Halving the denominator doubles the length drawn for the same real distance. |
| 9 | 600 metres. | Twelve millimetres is 1.2 cm, and each centimetre stands for 500 m. |
| 10 | No. Both sides use the same unit, so 1 cm represents 20 000 cm. | Mixing centimetres with metres on the two sides would make the answer wrong by a factor of one hundred. |
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.
