A forest where trees are widely scattered

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

Question. Hachuring
Answer:
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
Answer:
It is a raised metalled road over a small water body. (Usually road used only in the non rainy months.)

Question. Spot Height
Answer:
The height of random places between contours shown with a dot. E.g. – 425
