Based on the contour lines on the map, point A is positioned at the highest altitude. This can be inferred because the contour lines are closer together around point A, indicating a steeper slope, which is typically associated with higher altitudes. The other points, B, C, and E, are located in areas with contour lines that are further apart, suggesting lower altitudes.

Point A is WNW (West-Northwest) of point C. In the diagram, point C is located towards the north, and point A is positioned towards the west-northwest direction from point C.

A compass typically has four cardinal points, which are North, South, East, and West. These points represent the four main directions on the compass and are used for navigation purposes.

The contour interval of a map refers to the vertical distance between adjacent contour lines. In this case, the given answer is 20 metres. This means that each contour line on the map represents a change in elevation of 20 metres.

A scale shown as a representative fraction is a ratio that represents the relationship between distances on a map and distances on the ground. The numerator of the representative fraction represents the number of units on the map, while the denominator represents the number of corresponding units on the ground. Therefore, statement 2 is true because the numerator is always one, and statement 3 is true because the numerator represents the number of units on the map.

The grid reference for point B is GR 582178 because the first two digits represent the easting, which is the horizontal coordinate, and the last three digits represent the northing, which is the vertical coordinate. In this case, the easting is 58 and the northing is 217, so the correct grid reference is GR 582178.

The correct answer is 6.15 minutes. To calculate the time it takes to travel a certain distance, we can use the formula: Time = Distance / Speed. In this case, the distance is 8.2 km and the speed is 80 km/hr. Plugging these values into the formula, we get Time = 8.2 km / 80 km/hr = 0.1025 hours. To convert this to minutes, we multiply by 60, giving us 0.1025 hours * 60 minutes/hr = 6.15 minutes. Therefore, the journey would take 6.15 minutes.

The correct answer is 1cm to 500 metres. This means that on the linear scale, 1 centimeter represents a distance of 500 meters.

The direction of point D from point C is NW, which stands for northwest. This means that point D is located in the direction between the north and the west from point C.

Based on the contour map, the area for the grid square in which point B falls can be determined by looking at the grid lines and counting the number of grid squares that cover the area. From the given options, the only option that matches the number of grid squares is 4 kilometres square. Therefore, the correct answer is 4 kilometres square.

The correct answer is 5619. This is because the contour lines on the map indicate the elevation of the land. By examining the contour lines around point D, it can be determined that the area reference for point D is 5619, as this is the closest contour line to the point.

Based on the contour map, the distance between point B and point D can be estimated by measuring the straight line distance between the two points. By visually analyzing the map, it can be observed that the closest estimate is 5 kilometres.

Large scale maps show relatively large areas of land with good detail, while small scale maps show relatively large areas of land with little detail. Therefore, statements 3 and 4 are true.

When 1cm on a map represents 1km on the earth's surface, the map scale would read as 1:100 000. This means that every 1 unit on the map represents 100 000 units on the actual ground. So, for every 1cm on the map, it represents 100 000cm (or 1km) on the earth's surface.
