Question. Representative fraction (RF)
Answer: It is the ratio between the distances on the map to its corresponding distance on actual ground. The RF on this map is 1:50,000.

Question. Relative Height
Relative Height is the height of a feature with reference to the height of the surrounding land and NOT to sea level. It is represented by the height with a small ‘r’ eg – 12r.

Question. Embankment
They are raised rock or soil filled constructions on which roads/railway tracks are built. Also made near tanks and rivers to prevent flooding.

Question. Dep
It is a depression often found in sandy areas where the wind, having blown away the sand, leaves a hollow or a depression.

Hill shading resembles a light and shadow effect. Valleys and the sides of mountains appear as though they are cast in shadow. This is a visually striking method, which is ideal for providing an overall view of the relief of an area. Hill shading, however, does not show height which means that is no more accurate than hachuring

Question. Brackish
It is a well, which has water with very high salt content which is unfit for drinking purposes.

Question. Mixed Forest
A forest with more than two varieties of trees growing in close proximity to each other.

Question. Stony Waste
A large area usually in arid/semi-arid regions where the finer sand/ soil has bown away leaving a surface covered with boulders, stones and pebbles.

Question. Open Jungle
A forest where trees are widely scattered

Question. Dense Jungle
A forest where trees grow very close to each other.

Question. Hachuring
Early cartographers attempted to show surface features on maps by using the technique of hachuring. Hachures short lines of varying thickness to show the shape and slope of the land. In accordance with this technique, the steeper the slope is, the thicker the lines are which represent it. While hachuring was initially innovative for its time, it gradually began to be replaced since the actual height of the land was not depicted.

Question. Causeway
