Question
What is a grid reference and in what order is it read?
Answer
Numbers locating a place: **eastings** (read across) first, then **northings** (read up) -- 'along the corridor, then up the stairs'.
Question
Four-figure vs six-figure grid reference?
Answer
**Four-figure** names a whole grid square (1911); **six-figure** splits the square into **tenths** to pin an exact point (194115).
Question
How do you give a six-figure grid reference?
Answer
Find the four-figure square, then estimate **tenths across** (easting) and **tenths up** (northing), and combine.
Question
What does a 1:50 000 scale mean?
Answer
1 cm on the map = **0.5 km** (500 m) on the ground; multiply measured cm by 0.5 to get km.
Question
Convert 3 cm on a 1:50 000 map to a real distance.
Answer
3 x 0.5 = **1.5 km** on the ground.
Question
How do you read a compass direction from A to B?
Answer
Stand at A and face B; read **N/NE/E/SE/S/SW/W/NW** from the way you must travel.
Question
How do you read a value off a time-series graph?
Answer
Find the time on the x-axis, go up to the line/bar, read the **y-axis value** across -- quote it with its unit.
Question
How do you calculate the difference between two peaks?
Answer
Read both peak values and **subtract** the smaller from the larger.
Question
What does a skills read need to score the mark?
Answer
The **exact figure with its unit** (km, grid digits, index value) -- a trend word alone scores nothing.
Question
Name one real urban graph students read in Option G.
Answer
A congestion index (Lagos), a pollution time-series (Barcelona superblocks), or a road-pricing graph (Singapore).
