5. (a) Name the two types of dams shown in the given map extract.
   (b) How does the drainage pattern in grid square 2698 differ from the pattern of streams in grid square 2697?

Answer 1

1. (a) 2891
   (b) 333964
2. (a) Ratanpur lies in north-east direction of Marwada.
   (b) Dantiwada, south of river Banas has a Post Office, two Rest Houses, overhead tanks and a network of metalled roads.
3. (a) The brown dotted clusters in the southern part of the given map extract are sand features like sand dunes and sand hills. The letters 'Dep' are short form of the word 'Depression', which is a hollow found in sandy areas. It is formed by winds which blow away the surface sand and leave behind a depression.
   (b) Some of the streams in the given map extract do not join the main river as they flow over sandy soil, which absorbs the water before these streams join the main river. The streams around Ramsida are examples of such streams.
4. (a) The general pattern of settlements in the given map extract is nucleated or clustered.
   (b) Map distance = 3.2 cm. Since scale is 2 cm = 1 km, the actual distance is 1.6 km.
5. (a) The two types of dams shown in the given map extract are - (i) masonry dam, and (ii) earth work dam.
   (b) The drainage pattern in the grid square 2698 is trellised and in grid square 2697 is dendritic.
