C – Western Ghats

(iii)

(a) Typical characteristic feature of Tropical Deciduous forests are :

1. These forests are found in areas receiving 100 – 200 cm of annual rainfall.
2. These trees shed their leaves in the beginning of summer season due to shortage of water.
3. Although the trees shed their leaves in summer, each species has its own time. As a result, the forests never look absolutely bare at any time. These forests are quite dense with an undergrowth of creepers.

(b) Sal and Teak.

(iv) Regular pruning is done to keep the shrubs at the required height of 1 m to facilitate plucking and the growth of new shoots with softer leaves.

(v) Two demerits of tube well irrigation are :

1. Wells dry up during the dry summers and fail to provide water.
2. As tubewells can draw out larger quantities of water, largescale depletion of ground Water takes place, the groundwater level or the water table goes down.

(vi)

(a) Coffee plant requires hot and humid climate with 15°C to 30°C and 150-200 cm rainfall. Frost is injurious to the growth of coffee plants.
(b) Karnataka.

(vii) Use of renewable power resources is on the rise because:

1. Exhaustible resources such as coal, mineral oil, etc., are fund or stock resources with limited to time-span which will not last long.
2. Non-conventional energy resources are cost efficient in the long run as the material cost is nil.

(viii) Intensity of cropping refers to the number of crops raised on a field during an agricultural year.

The total cropped area as a percentage of the net sown area gives a measure of cropping intensity. The state with the highest index of intensity is Punjab and lowest index of intensity is Mizoram.

(ix) The Chota Nagpur industrial region is also known as the ‘Ruhr of India’ because :

• Different types of minerals like coal, iron ore, bauxite, mica, etc., are available in this region.

(b) State three differences between compact settlements and dispersed settlements. [3]
(c) Give three positive consequences of migration. [3]
(a)

(i) According to the population estimates of India, till 1871, Indian’s population recorded a modest growth. Since then the population has been increasing consistently. However, in 1921, population growth declined to 0.30% caused by large-scale deaths caused by diseases like influenza, plague, cholera etc. This is why 1921 is called the ‘demographic divide’.

(ii) During 1921-1951, the population of India increased from 251 million to 361 million, registering a growth rate 47.3%. During 1951¬1981, the population nearly doubled from 361 million to 683 million, a growth rate of 89.2%. In 2001, the population stood at 1027 million registering a growth rate of about 50%. This is why the period from 1951-1981 is referred to as the period of population explosion.

(b)

 Compact Settlement Dispersed Settlement (i) It is usually found in fertile plains of river valleys. It is found in mountainous highlands, ridges, forested areas and deserts and semi­deserts. (ii) Main occupation is agriculture. Main occupation is cattle rearing, lumbering, etc. (iii) The houses are located adjacent to each other and form a compact block. The houses are located at a distance from each other.

(c) Positive consequences of migration are as follows:

• Economic in Nature : Remittances, both from international and internal migrants, to their families home add to the economic prosperity.
• Social in Nature : Migrants are agents of social change, as they bring with them new ideas. Migrations helps in the intermixing of diverse cultures. It widens the mental horizons of people.
• Rural to urban migration also helps in urban development.

(a) Tank irrigation is not used by all farmers because:

• Only limited area can be irrigated.
• Most tanks dry up in the dry season when water is most needed.
• Tanks cover large areas of cultivable land. In many areas, other sources of irrigation have been adopted and the dry beds of the tanks have been reclaimed for agriculture.

(b)

(i) The need to conserve water has become greater in recent times because of growing population pressure which has resulted in the depletion and pollution of the groundwater.
(ii) Developing water saving technologies and encouraging watershed development, rainwater -harvesting, reuse and recycling of water should be undertaken for the conservation of water.

(c) Two demerits of canal irrigation are :

1. Farmers tend to flood their fields with water with the intention of getting a bumper crop. They also wish to get the maximum benefit from the money they have spent to use the facility of canal irrigation.
2. Marshy areas near canals become breeding grounds for mosquitoes.

(d) Two methods by which the problem of limited agricultural land may be solved are :

1. By reducing the extent and frequency of fallow land by the use of fertilizers, irrigation, crop rotation and combination.
2. Green revolution / Intensive agricultural method.

Question 6.

(ii) Compare wheat cultivation in India and China-with reference to the varieties grown.
(c) Why is mica used in the electrical and electronic industry? [1]
(d) Mention two problems affecting the fishing industry in Bangladesh. [2]
(a) Change in technology in Indian agriculture started in 1960s with the introduction of high yielding variety of seeds, fertilizers and mechanisation. These modern inputs require assured water supply to the crops.
The four modern inputs are as follows :

1. High Yielding Variety of Seeds:
HYV seeds are the product of modem technology. It has increased the yield per hectare tremendously. Now, HYV seeds are used in almost every crop. New HYV of seeds for wheat and rice were brought to India from Mexico and Philippines respectively. HYV seeds for jowar and maize were also introduced. The use of HYV seeds increased the production of crops phenomenally. In 1966 – 67, area under HYV of seeds was only 1.89 million hectares and increased to 71.3 million hectares in 1994 – 95. In 2001, 90.6 percent of total wheat cropped area is under HYVs.

Example of HYV seeds are :
Wheat: Kalyansona, Sonalika.
Rice: IR – 36, IR – 58.

2. Fertilizers:
The use of fertilizers is an important factor of modern technological inputs in the agricultural field. The production and consumption of fertilizers has increased many fold after the independence. The consumption of fertilizers was only 760 thousand tones of nutrients in 1965-66. It rose to an all times high of 18,069 thousand tones nutrients in 1990-2000.

3. Modern Equipment’s of Agriculture:
The modern equipments of agriculture have made the agriculture productive and easy.

4. Irrigation:
The supply of water for irrigation through canals or tube wells has increased the production of crops and has also led to the increase in net cropped area

(b) (i) The cultivation of wheat requires a temperature of 10°C while sowing and 15°C- 20°C during repening. Average annual rainfall of 50-70 cm is also suitable for the cultivation of crops.
(ii) In India, wheat is a Rabi crop-therefore, winter wheat is grown whereas in China both winter and spring wheat are grown.

(c) Mica has insulating properties which can withstand high voltage and has low power loss factor. This has made mica useful in the electrical and electronic industry.

(d) Two problems affecting fishing industry in Bangladesh are :

• The cyclonic storms which originate in the Bay of Bengal pose a serious threat to the fisherman.
• Traditional and inefficient methods used for fishing poses a limitation for the expansion of the fishing industry.

(d) Telecommunication is the modem device for the communication at individual and mass level. It has facilitated the communication of messages within a short span of time. It consists of transmission of word messages and ideas.
The main components of telecommunication are telegraph, telephone, fax, radio, television and internet.
