Study the extract of the Survey of India Map sheet No. 45D/10 and answer the following questions:
(b) What is the difference in the pattern of drainage in grid square 0916 and in 0712 ?
(c) Give the four figure grid reference of each of the following:
(i) Stony waste
(ii) Open scrub.
(d) Calculate the distance in kilometres along the metalled road between the causeways in grid square 0512 and 0808.
(e) (i) What do the tiny curved black line in grid square 0315 indicate ?
(ii) What is the main cause for this feature ?
(f) (i) What is the geographical name that you would give to the general pattern of settlements in the region shown on the map ?
(ii) Give a reason for your answer.
(g) What is the general direction of flow of the Sipu Nadi, given in the map extract ? Give a reason to support your answer.
(h) Name two probable occupations of the people in the settlement of Revdar in grid square 0313 and 0413.
(i) What kind of roads connect
(i) Marol with Mitan and
(ii) Revdar with Karaunti respectively ?
(j) Give two reasons to show that the area depicted in the map experiences seasonal rainfall.
(b) Pattern of drainage in square 0916 is Radial and in 0712 is trellis.
(c) Four figure grid reference of:
(i) Stony waste —1014
(ii) Open Scrub — 0916
(d) Distance along the metalled road between the causeways is 11.2 cm.
Distance in km = 11.2 / 2 (Scale 2 cm to 1 km) = 5.6 km
(e) (i) Tiny curved black lines in grid sq. 0315 indicate broken ground.
(ii) Main cause for this feature is erosion by running water due to rains in rainy season.
(f) (i) The geographical name given to the general pattern of settlement is Nucleated.
(ii) Because the settlements can be seen in clusters.
(g) The general direction of flow of the Sipu Nadi is from NE to SW.
Reason — An arrow in the river bed in sq. 1014 is indicating the flow of the river towards S.W.
(h) Two probable occupations of the people of Revdar are services and farming.
(i) (i) Road that connect Marol with Mitan is cart track and
(ii) Revdar with Karaunti is metalled road.
(j) Two reasons for seasonal rainfall in the given area are :
(1) Seasonal rivers and streams.
(2) Presence of broken ground.
Give two important characteristics of the summer monsoon rainfall in India.
Two characteristics of the summer monsoon rainfall are :
i. It is erratic in nature.
ii. It is mainly orographic in nature.
‘Rainfall in India is Orographic in nature.’ Give an example with reference to the distribution of rainfall and the effect of relief on its distribution.
‘Rainfall in India is Orographic in nature. Example Western Ghats which he parallel to the western coast is in a suitable direction to check the rain bearing monsoon winds. The western slope of it that faces the winds receives heavy rainfall i.e. inore than 200 cms. whereas the leeward side of it is not able to do so as the winds are descending on that slope. This region receives low rainfall.
Give a reason to explain why :
(i) the coastal areas of India do not experience a significant variation in temperature between summer and winter months.
(ii) the annual rainfall in Rajasthan is less than 25 cm.
(iii) the Coromandel coast gets most of its rain during the winter season.
(i) This is because of the moderating influence of the adjoining water bodies. The land and sea breezes moderate the temperatures.
(ii) This is because Aravallis are parallel to the Arabian sea branch of S.W. monsoons and are unable to check the winds. This is also because Rajasthan lies in the rain shadow region when Bay of Bengal Branch strikes the Aravallis.
(iii) Coromandel coast gets most of its rain during winter season because of N.E. monsoons which pickup moisture from Bay of Bengal and strikes the Coromandel coast.
