Model activity task class 8 Geography part 2

All the answers of the class 8th model activity task for geography part 2 is given below one by one.

1. Answer the following questions.

(i) Which are the two main climatic factors responsible for soil formation?


The two main climatic factors responsible for soil formation are temperature and rainfall. Temperature affects the rate of chemical reactions and the biological activities in the soil. Higher temperatures speed up these processes, leading to faster soil formation. On the other hand, rainfall influences the leaching and transportation of minerals within the soil.

It helps in the weathering of rocks and their subsequent breakdown, contributing to the formation of different soil layers. Both temperature and rainfall play crucial roles in determining the composition, fertility, and characteristics of soils.

(ii) Write any two reasons for land degradation today?


Two reasons for land degradation today are deforestation and unsustainable agricultural practices. Deforestation leads to soil erosion, loss of biodiversity, and disruption of ecosystems. Unsustainable agricultural practices such as overuse of fertilizers, improper irrigation, and excessive tillage degrade the soil quality, decrease fertility, and contribute to land degradation.

(iii) Why is land considered an important resource?


Land is considered an important resource because it provides the foundation for human habitation, agriculture, and various economic activities. It serves as a crucial base for infrastructure development, housing, industries, and natural resource extraction. The land also supports ecosystems, and biodiversity, and provides vital ecosystem services such as water filtration, climate regulation, and nutrient cycling

(iv) Name any two steps that the government has taken to conserve plants and animals?


The government has taken two steps to conserve plants and animals: establishing protected areas such as national parks and wildlife sanctuaries, and implementing laws and regulations to prohibit hunting, poaching, and trade of endangered species.

(v) Suggest three ways to conserve water?


The following three ways to conserve water are given below in points:

  1. Practice water conservation at home by fixing leaks, using water-efficient appliances, and taking shorter showers.

2. Promote efficient irrigation techniques in agriculture, such as drip irrigation and using drought-tolerant crops.

3. Raise awareness about water conservation through educational campaigns and community initiatives.

Tick the correct answer

(i) Which one of the following is NOT a factor of soil formation?
(a) time

(b) soil texture

(i)Land use – (c) productive use of land

(ii) Humus – (d) organic matter deposited on top soil

 (iii) Rock dams – (a) prevent soil erosion

(iv) Biosphere – (b) narrow zone of contact between the lithosphere, hydrosphere, and atmosphere

 (v) Contour ploughing – (e) contour ploughing

State whether the given statement is true or false.
If true, write the reasons

(i) Ganga–Brahmaputra plain of India is an overpopulated region?


The statement “Ganga-Brahmaputra plain of India is an overpopulated region” is true. Because the Ganga-Brahmaputra plain is densely populated due to factors such as fertile soil, ample water resources, and historical settlements. The region supports intensive agriculture and has a high population density, making it an overpopulated area in India.

(ii) Water availability per person in India is declining?


The statement “Water availability per person in India is declining” is true.

Because the declining water availability is primarily due to the increasing population, industrialization, urbanization, and inefficient water management practices, leading to overexploitation and depletion of water resources.

(iii) Rows of trees planted in the coastal areas to check the wind
movement is called intercropping?


The statement “Rows of trees planted in the coastal areas to check the wind movement is called intercropping” is false.

Because Intercropping refers to the practice of growing different crops in proximity to increase agricultural productivity. The correct term for planting rows of trees in coastal areas to check wind movement is shelterbelts or windbreaks.

(iv) Human interference and changes of climate can maintain the ecosystem?


The statement “Human interference and changes in climate can maintain the ecosystem” is false.

Because the Human interference can disrupt and degrade ecosystems, while changes in climate can have detrimental effects on ecosystems, leading to loss of biodiversity and ecological imbalances.


Discuss some more reasons which are responsible for changes of land use pattern.
Has your place undergone any change in the land use pattern in recent years?


some of the reasons responsible for changes in land use patterns include urbanization, industrialization, agricultural expansion, infrastructure development, population growth, and natural disasters. And in my area, there are some agricultural use and some infrastructure development is the main use of land.
