Explain the difference between a 4-figure grid reference and a 6-figure grid reference.

• A 4-figure grid reference is used for small-scale maps, while a 6-figure grid reference is used for large-scale maps.

• A 4-figure grid reference uses four letters to represent a location within a 1km square on a map, while a 6-figure grid reference uses six letters to provide a more precise location within that 1km square.

• A 4-figure grid reference uses four digits to represent a location within a 1km square on a map, while a 6-figure grid reference uses six digits to provide a more precise location within that 1km square.

• A 4-figure grid reference is used for urban areas, while a 6-figure grid reference is used for rural areas.

How do you accurately locate a point on a map using a grid reference?

• Use a compass to draw a circle around the general area

• Ask a passerby for directions

• Count the number of trees in the vicinity

• Identify the eastings and northings on the map's grid and use the numbers to pinpoint the exact location within the specific grid square.

What is the significance of the eastings and northings in a grid reference?

• They indicate the temperature and humidity of the location

• They represent the number of trees and buildings in the area

• They help to accurately locate a specific point on a map by providing a coordinate system for navigation and measurement.
