ii. The irregular black lines along the Sarod Nala in the square whose four figure grid reference is 8284.
Broken ground

c. State two advantages that Dantiwada (South of River Banas) has over other settlements in the region?
Post office and Inspection Bungalow


d. What does 6r written against the unmetalled road in grid square 8478 mean?.
It is the relative height or steepness of the road which is 6 metres.


e. What is the direction of the River Banas and on which bank of the river is village Nadotra (Brahmanivas) located.?
The general direction of the river is east to west. Village Nadotra (Brahmanivas) is located on the right bank of the river.


f. What does “Dep” mean in the grid square 8777?
It means Depression. Depression is generally written on the map in a dry area where the wind has carried away the soil and leaving behind a hollow.

g. What is the general pattern of human settlement in the map extract?
Dispersed.

h. What is the area in square kms of the cultivated region enclosed by vertical grid lines 82 and 84 and the horizontal grid lines 78 and 80?
On the given map each grid square measures 2 cm X 2cm or 1 km X 1km

Therefore the area of each square is 1 sq km.

The number of squares between Eastings 82 and 84 and Northings 78 and 80 is 4.

Therefore the total area is 4 square kms.


i. In the south-east part of the map, why do some of the streams do not join the main river?
In the sandy areas, the streams have disappeared either due to sandy soil or high rate of evaporation.

j. What is the length of the canal under construction in kms?
2 cms on the map represents 1 km on the ground.
The length of the canal on the map is 4 cms.
Therefore 4 cms on the map represents 2 kms on the ground. So the length of the canal under construction is 2 kms.

QUESTION 2 [10x1=10]
On the outline of map provided, mark and name:
a. The Capital of Nepal
b. The Rann of Kutch
c.The Eastern Coastal Plains

j. A region of black soil in India.

PART II (50marks)

QUESTION 3 [2+2+3+3=10]
a. What is a land locked country? Name two landlocked SAARC countries.
A LANDLOCKED COUNTRY IS COMMONLY DEFINED AS ONE ENCLOSED OR NEARLY ENCLOSED BY LAND. BHUTAN AND NEPAL.


b. What are Tarai? Where exactly are they located?
THE WORD TARAI, A TERM PRESUMED TO BE DERIVED FROM PERSIAN, MEANS "DAMP," AND IT APPROPRIATELY DESCRIBES THE REGION'S HUMID AND HOT CLIMATE. THE REGION WAS FORMED AND IS FED BY MAJOR RIVERS.


c. Distinguish between an East-flowing and a West-flowing river.
1. EAST FLOWING
THE MAIN EAST FLOWING RIVER SYSTEMS ARE THE GANGES RIVER, THE INDUS AND THE BRAHMAPUTRA RIVER SYSTEMS.
THE EAST FLOWING RIVERS FORM LARGE BASINS. MANY RIVERS PASS THROUGH THE HIMALAYAS. THESE DEEP VALLEYS WITH STEEP ROCK SIDES WERE FORMED BY THE DOWN - CUTTING OF THE RIVER DURING THE PERIOD OF THE HIMALAYAN UPLIFT. THEY PERFORM INTENSE EROSIONAL ACTIVITY UP THE STREAMS AND CARRY HUGE LOAD OF SAND AND SILT. IN THE PLAINS, THEY FORM LARGE MEANDERS, AND A VARIETY OF DEPOSITIONAL FEATURES LIKE FLOOD PLAINS, RIVER CLIFFS AND LEVEES.THESE RIVERS ARE PERENNIAL AS THEY GET WATER FROM THE RAINFALL AS WELL AS THE MELTING OF ICE. NEARLY ALL OF THEM CREATE HUGE PLAINS AND ARE NAVIGABLE OVER LONG DISTANCES OF THEIR COURSE. THESE RIVERS ARE ALSO HARNESSED IN THEIR UPSTREAM CATCHMENT AREA TO GENERATE HYDROELECTRICITY.
2. WEST FLOWING RIVER
THE MAIN WEST FLOWING RIVER SYSTEMS INCLUDE THE NARMADA, THE TAPI, THE GODAVARI, THE KRISHNA, THE KAVERI AND THE MAHANADI RIVER SYSTEMS.
THE WEST FLOWING RIVERS FLOW THROUGH SHALLOW VALLEYS. A LARGE NUMBER OF THEM ARE SEASONAL AS THEIR FLOW IS DEPENDENT ON RAINFALL. THE INTENSITY OF EROSIONAL ACTIVITIES IS ALSO COMPARATIVELY LOW BECAUSE OF THE GENTLER SLOPE. THE HARD ROCK BED AND LACK OF SILT AND SAND DOES NOT ALLOW ANY SIGNIFICANT MEANDERING. MANY RIVERS THEREFORE HAVE STRAIGHT AND LINEAR COURSES. THESE RIVERS PROVIDE HUGE OPPORTUNITIES FOR HYDRO-ELECTRIC POWER.

d. Which are the States in India that receive winter rain? How is this rain economically beneficial?
TAMIL NADU COAST. ABOUT 60-70% OF THE RAINFALL OCCURS DURING THIS TIME. IMPORTANT FOR RABI CROPS, RECHARGE OF NON PERINIAL RIVERS ETC.


QUESTION 4 [2+2+3+3=10]
a. What are the main factors that determine the development of industries in a region? (any two points)
Factors responsible for location of industry
• HUMAN FACTORS:-
• CAPITAL – Big cities like Mumbai, Kolkotta, Delhi, Chennai are big industrial centres because the big capitalists live in these cities.
• GOVERNMENT POLICIES:- Government activity in planning the future distribution of industries, for reducing regional disparities, elimination of pollution of air and water and for avoiding their heavy clustering in big cities, has also become an important locational factor.
• MARKET – The entire process of manufacturing is useless until the finished goods reach the market. Nearness to market is essential for quick disposal of manufactured goods. It helps in reducing the transport.

OTHER FACTORS
• Availability of raw materials
• Power resources,
• Transport and communication facilities
• Skilled and unskilled labour,
• Favourable climate
• Capital
• Water resources
• Market
• Government policy

b. Name a plantation crop. Mention two characteristics of plantation farming with reference to this crop.
Tea is a plantation crop.
Climatic Requirements: Temp - 13 degree C - 35 degree C,
Rainfall - 150 cms -250 cms

c. Which are the two staple crops of India? Mention the agricultural season in which each they are grown.
Rice and Wheat
Rice- Kharif
Wheat- Rabi

d. Which is the most densely populated country of South Asia? Give two reasons for this.

d. Where do you find red soil in India? What are its disadvantages?

QUESTION 7 [2+2+3+3=10]
a. What does soil formation depend on? (any two)
Ans: i) WEATHERING: Extremes of temperature (as in the day and night temperatures in deserts), freezing and thawing of ice break down rocks, and favour soil formation.
ii) VEGETATION: The growth and decay of vegetation determines the humus content of the soil. Roots of plants penetrate the soil and make it porous.
iii. Bio-chemical processes taking place in the soil: Bacteria and fungi cause the decay of plants and animal remains. Some transform the atmospheric nitrogen into soil nitrogen.
iv. CLIMATE : Climate is the most important single factor in the soil formation. the amount of rainfall and range of temperature are the most important climatic factors affecting soil formation.
v. RELIEF: Low relief areas generally experience deposition and have deep layer of soil whereas the soils are generally shallow in the plateau areas.
vi) PARENT MATERIAL: Parent rock determines the composition of soil
.



b. How is man responsible for soil erosion?
Soil erosion is the removal of soil by the forces of nature, particularly wind and water. Soil erosion mainly takes place due to man’s activities such as deforestation, overgrazing of cattle, faulty methods of cultivation.

c. Which is the most expensive soil in India? How has it been formed? State one
characteristic feature of this soil.




d. Mention any two important aspects of hydro-electrical power in South India.




QUESTION 8 [2+2+3+3=10]

b. How can the desert be protected from erosion?




c. Where is desert soil found in India? Mention its characteristics.
Because fine topsoil particles are removed by fast-blowing winds.
Because of low water retention power and very low humus content, desert soils are unsuitable for
farming. However, under irrigation they can yield rich crops.
Rajasthan, North Gujarat and Southern Punjab



d. Which are the two States in India that lead in iron-ore production? What is its main use?

QUESTION 9 [2+2+3+3=10]
a. Why is South Asia considered a region of great physical diversity? Give two examples.
DUE TO THE PRESENCE OF THAR DESERT, DECCAN PLATEAU, HIMALAYAS, COASTAL PLAINS, RIVER PLAINS ETC.

b. In reference to the Malwa Plateau:
(i) Where is it located?
(ii) Name the rivers that drain it.
(iii) What is it made up of?
MALWA PLATEAU IS LOCATED BETWEEN THE ARAVALLIS AND THE VINDHYAS. THE ARAVALLIS LIE TO ITS WEST AND THE VINDHYAS LIE TO ITS SOUTH.
CHAMBAL, SIND AND BETWA ARE THE RIVERS THAT DRAIN IT.THEY WERE FORMED BY SOLIDIFIED MOLTEN LAVA. THE FLAT TOP IS FORESTED AND BROKEN BY RAVINES

c. Describe briefly the climatic conditions required for the cultivation of rubber.




d. Into how many drainage systems can the rivers of Peninsular India be grouped? Which is the longest river here and where does it originate?
RIVERS OF PENINSULAR INDIA CAN BE GROUPED INTO EAST FLOWING TOWARDS BAY OF BENGAL AND WEST FLOWING TOWARDS ARABIAN, TOWARDS GANGA, I.E. FLOWING NORTH FROM THE VINDHYAS, GODAVARI, RISING IN THE WESTERN GHATS.

QUESTION 10 [2+2+3+3=10]
(a) Mention two differences between the cyclonic rain in Bangladesh and the cyclonic rain in Pakistan.
BANGLADESH:- OCCURS IN SUMMER, OCCURS BECAUSE OF TROPICAL CYCLONE.
PAKISTAN :- :- OCCURS IN WINTER, OCCURS BECAUSE OF WESTERN DISTURBANCES.


(b) Why is Pakistan often described as the 'Gift of the Indus'? Give two reasons.
WITHOUT THE PRESENCE OF THIS RIVER PAKISTAN WOULD HAVE BEEN A DESERT REGION. THE LONGITUDINAL EXTENT OF THE RIVER PROVIDES LIVELIHOOD TO THE PEOPLE OF PAKISTAN.

(c) Mention three differences between the Western Ghats and the Eastern Ghats.
1. WESTERN GHATS :- IT RUNS PARRELL TO THE WEST COAST.AVERAGE ELEVATION IS 900-1100 MTS. IT IS A CONTINUOUS WALL.SOURCE OF THREE LARGEST PENINSULAR RIVERS. LIES ALMOST PERPENDICULAR TO SOUTH EAST MONSOON.
2. EASTERN GHATS :- IT RUNS PARRELL TO THE EAST COAST. AVERAGE ELEVATION IS 600 MTS. IT IS A BROKEN WALL.DISECTED BY PENINSULAR RIVERS. LIES ALMOST PARALLEL TO SOUTH EAST MONSOON ORIGINATING FROM BAY OF BENGAL.

(d) Give three reasons why Bangladesh is one of the most densely populated countries in the world.
