Chapter – 7
| Geography |
Exercise
1. Answer the following questions:
(a) What is the name of the national park situated at the extreme west direction of Assam?
Ans: The name of the national park situated at the extreme west direction of Assam Manas National Park.
(b) What are the major characteristics of evergreen vegetation?
Ans: Tropical evergreen forests in Assam typically grow in areas where rainfall is around 200 cm and temperatures are about 25°C, characterising the hot, humid regions with a short dry season. These forests are found in the foothills of the Brahmaputra Valley, particularly in the north-eastern margins, North Cachar Hills, and the Barak Valley. In these forests valuable trees like Mahogany, Jamu, Bamboo, Sishu, Amri, Sandalwood, Khokan, etc. are found. he trees shed their leaves during different times of the year. Hence, these forests look evergreen. Nameri of Sonitpur, Joy Dihing and Pani Dihing of Tinsukia district are examples of such rainforests.
(c) In which district of Assam Manas wildlife sanctuary is located?
Ans: Manas Wildlife Sanctuary is located in the Baksa district of Assam.
(d) What do you mean by natural vegetation?
Ans: Natural vegetation refers to plant communities that have developed naturally, without human intervention, and have been left undisturbed for a long time. This type of vegetation is often termed virgin vegetation.
2. Write the answers briefly:
(a) What do you mean by climate?
Ans: Climate is the general weather over a long period. This can include rainfall, temperature, snow or any other weather condition. We usually define a region’s climate over a period of 30 years. It influences the environment and ecosystems, shaping the natural landscape and affecting human activities and agriculture.
(b) How many seasons are experienced in Assam? Name them accordingly.
Ans: There are four seasons are experienced in Assam Summer, Monsoon, Winter, Autom.
(c) Why is rainy season suitable for rice production?
Ans: The rainy season is suitable for rice production because it is a kharif crop which is sown in the rainy season. It requires a lot of water for its growth which is grown only in the rainy season. This continuous water supply is essential for the growth and development of rice crops.
(d) How is climate related to agriculture?
Ans: Climate plays a crucial role in agriculture by influencing crop growth, soil health, water availability, and pest populations.Climate change can affect agriculture in a variety of ways. Beyond a certain range of temperatures, warming tends to reduce yields because crops speed through their development, producing less grain in the process.
(e) Distinguish between Evergreen and Deciduous vegetation.
Ans: Evergreen: Evergreen forests are so dense that sunlight does not reach the ground. creating a shaded environment.
Deciduous vegetation: The deciduous forests are not so dense as in case of Evergreen forest.
Trees of Evergreen forests shed their leaves at different times of the year . In case of deciduous forests they have a particular time(autumn or winter) for their leaves to shed.
(f) Why do we need vegetation?
Ans: Vegetation converts solar energy into biomass and forms the base of all food chains. Vegetation influences the energy balance at the earth’s surface and within the atmospheric boundary layer, often mitigating extremes of local climate. vegetation releases oxygen and sequesters carbon, contributing to atmospheric stability and climate regulation.
(g) Why do we need conservation of vegetation and wildlife?
Ans: Wildlife should be conserved because it maintains ecological balance. as wildlife has a crucial role in ecosystems. Animals and forests are interconnected, with wildlife supporting diverse ecological functions. Have equal rights to stay on this planet. Association between wildlife and forests sustains an ecosystem.
3. Fill up the gaps:
(a) The average condition of a place for about 50 years of sunshine, temperature, air, pressure, rainfall, humidity is called ________.
Ans: Climate.
(b) Based on the variation in climatic condition of Assam whole year has been divided into__________ seasons.
Ans: Three.
(c) Position of Assam in respect of tea production among the states of India is________.
Ans: Second.
(d) Rainfall during rainy season in Assam occurs due to__________.
Ans: Monsoon winds.
(e) At present there are ________wildlife sanctuaries in Assam.
Ans: 17.
(f) Kaziranga National Park is famous for __________.
Ans: One- horned rhinoceros.
(g) Days are short and night are__________during winter,
Ans: Long.
4. Find out the correct answer:

(i) Cherrapunji.
(ii) Mawsynram.
(iii) Shillong.

(b) In which district of Assam Kaziranga national Park is located?
(i) Golaghat.

(iii) Marigaon.
(iv) Kamrup.
Ans: (i) Golaghat.
(C) The trees which shed their leaves once in a year is
(i) Deciduous
(ii) Evergreen
(iii) Grasslands.
Ans: (i) Deciduous.
(d) The gas released by vegetation is
(i) Carbon dioxide.
(ii) Oxygen.
(iii) Nitrogen.
Ans: (ii) Oxygen.
5. What are the differences between the agriculture in plains and the hills? Write.
Ans: The differences between the agriculture in plains and the hills are:
| Basic of difference | Agriculture in plains | Agriculture in hills |
| Soil | Generally possess deep, fertile soils (such as mollisols) that are well-suited for cultivating a wide range of crops. These soils are often abundant in organic matter and nutrients. | Soil can be thinner and less fertile, often needing more careful management (such as crop rotation and organic enhancements) to maintain productivity. Erosion can also be a major concern. |
| Water Availability | Plains often have better access to water sources like rivers, making irrigation easier and more extensive. | Water availability is more limited in hills, and irrigation systems are often smaller and dependent on streams or rainwater harvesting. |
| Farming Techniques | Mechanized farming is common in plains due to the flat terrain, allowing for efficient large-scale agriculture | Agriculture in hills is more labor-intensive, with traditional methods and manual labor being prevalent due to the challenging terrain. |
| Climate | Generally have a more uniform climate, which can be conducive to growing staple crops like wheat, corn, and rice. They may experience less variation in temperature and precipitation. | Climate can fluctuate considerably with altitude. Temperature drops as elevation increases, leading to more variable conditions. This can restrict the variety of crops that can be cultivated.. |
