Label the diagram below by writing the latitude next to the corresponding letters below the diagram.

Question 2:
The diagram shows lines of latitude on a globe. We need to identify the latitude for each labeled point.

• A. The line labeled A corresponds to $\boxed{\text{60° N}}$.
• B. The line labeled B corresponds to $\boxed{\text{0°}}$ (the Equator).
• C. The line labeled C corresponds to $\boxed{\text{20° S}}$.

Question 4:
Four-figure and six-figure grid references are used to locate positions on a map with varying levels of precision. A four-figure grid reference identifies a 1 km by 1 km square on the map, using two digits for the easting and two for the northing. A six-figure grid reference provides a more precise location within that 1 km square, pinpointing a 100 m by 100 m area. It achieves this by adding an extra digit to both the easting and northing, which estimates the position within the 1 km square.
