  • Question 2
    1 / -0
    Which of the following types of soil is found in the areas of Duars, Chos and Terai?
    Solution
    In the upper reaches of the river valley, i.e. near the place of the break of slope, the soils are coarse. Such coarse alluvial soils are more common in piedmont plains such as Duars, Chos and Terai.
    (1) Duars: These are foothills of eastern Himalayas in North east.
    (2) Terai: Belt of marshy land at the foothills of Himalayas in North India.
    (3) Chos: Foothills of Shivaliks in Punjab.
  • Question 3
    1 / -0
    Alluvial soils are very fertile and are ideal for the growth of sugarcane, paddy, wheat and other cereal and pulse crops. An adequate mix of which of the following minerals makes alluvial soil fertile?

    a. Iron in crystalline form
    b. Potash
    c. Phosphoric acid
    d. Lime
    Solution
    Alluvial soil is one of the best soils, requiring the least water due to its high porosity. The consistency of alluvial soil ranges from drift sand and rich, loamy soil to silt clays. Alluvial soil as a whole is very fertile. Due to its high fertility, regions of alluvial soils are intensively cultivated and densely populated. These soils contain an adequate proportion of potash, phosphoric acid, and lime which are ideal for the growth of sugarcane, paddy, wheat, and other cereal and pulse crops.
  • Question 4
    1 / -0
    Which of the following types of soil is suitable for growing tea and coffee after adopting appropriate soil conservation techniques?
    Solution
    Laterite is both a soil and a rock type rich in iron and aluminium and is commonly considered to have formed in hot and wet tropical areas. Laterite soils are mainly found in Karnataka, Kerala, Tamil Nadu, Madhya Pradesh, and the hilly areas of Odisha and Assam. After adopting appropriate soil conservation techniques particularly in the hilly areas of Karnataka, Kerala and Tamil Nadu, this soil is very useful for growing tea and coffee.
  • Question 5
    1 / -0
    Regur soils are black in colour and are ideal for growing
    Solution
    Black soils are mineral soils which have a black surface horizon, enriched with organic carbon that is at least 25 cm deep. Black soil is also called Regur soil. It is black in colour and ideal for growing cotton. This type of soil is typical of the Deccan trap (Basalt) region spread over North-West Deccan plateau and is made up of lava flows.
  • Question 6
    1 / -0
    Which of the following is incorrect about Agenda 21?
    Solution
    Agenda 21 is a non-binding action plan of the United Nations with regard to sustainable development. It is a product of the Earth Summit held in Rio de Janeiro, Brazil, in 1992. The Commission on Sustainable Development (CSD) was created in December 1992 to ensure effective follow-up of UNCED, to monitor and report on implementation of the agreements at the local, national, regional and international levels. It is a comprehensive plan of action to be taken globally, nationally and locally by organizations of the United Nations System, Governments, and Major Groups in every area in which human impacts on the environment.
  • Question 7
    1 / -0
    We must be aware of India's enormous diversity in the availability of resources for a balanced resource planning in the country. Which of the following regions in India has an abundance of water resources but lacks in infrastructural development?
    Solution
    Arunachal Pradesh has an abundance of water resources, but lacks in infrastructural development.
    Rajasthan has solar and wind energy resources but lacks in water resources.
    Ladakh has a rich cultural heritage but lacks in water resources, infrastructure and some vital minerals.
    Jharkhand, Chhattisgarh and Madhya Pradesh are rich in minerals and coal deposits.
  • Question 8
    1 / -0
    Which of the following can be considered as fallow land?
    Solution
    Fallow Land is the arable land not under rotation that is set at rest for a period of time ranging from one to five years before it is cultivated again, or land usually under permanent crops, meadows or pastures, which is not being used for that purpose for a period of at least one year. Arable land which is normally used for the cultivation of temporary crops but which is temporarily used for grazing is included.
  • Question 9
    1 / -0
    Top soil in mountains gets eroded easily by the flow of water. Which of the following methods is helpful in decelerating the flow of water down the slopes and thus, preventing top soil erosion?
    Solution
    Ploughing in a wrong way, i.e. up and down the slope, forms channels for the quick flow of water, leading to soil erosion. Contour ploughing is the farming practice of ploughing and/or planting across a slope following its elevation contour lines. These contour lines create a water break which reduces the formation of rills and gullies during times of heavy precipitation, allowing more time for the water to settle into the soil. In contour plowing, the ruts made by the plow run perpendicular rather than parallel to the slopes, generally resulting in furrows that curve around the land and are level. This method is also known for preventing tillage erosion.
  • Question 10
    1 / -0
    Which of the following soils consists of various proportions of sand, silt and clay?
    Solution
    Alluvial soils are soils deposited by surface water. You'll find them along rivers, in floodplains and deltas (like the Mississippi Delta), stream terraces, and areas called alluvial fans. The alluvial soil consists of various proportions of sand, silt and clay. Alluvial soils as a whole are very fertile. Mostly these soils contain adequate proportion of potash, phosphoric acid and lime.
  • Question 11
    1 / -0
    Which of the following statements is/are incorrect?

    a. Laterite soils are rich in soil nutrients, such as calcium carbonate, magnesium.
    b. Laterite soil develops in areas with high temperature and heavy rainfall.
    c. Laterite soils are mainly found in Karnataka, Kerala, Tamil Nadu, Madhya Pradesh and the hilly areas of Odisha and Assam.
    Solution
    The black soils are made up of extremely fine i.e. clayey material. They are well-known for their capacity to hold moisture. In addition, they are rich in soil nutrients, such as calcium carbonate, magnesium. These soils are generally poor in phosphoric contents. The laterite soil is formed under conditions of high temperature and heavy rainfall. They are the result of intense leaching due to alternate wet and dry periods. With rain, lime and silica get leached away and soils rich in iron oxide and auminium compound are left behind. Laterite soil and is mainly found on the summits of the Western Ghats, Eastern Ghats, Rajmahal Hills, Vindhyas, Satpuras and Malwa plateau, thus abundant in Karnataka, Kerala, Tamil Nadu, Madhya Pradesh and the hilly areas of Odisha and Assam.
  • Question 12
    1 / -0
    Which of the following soils is made up of lava flows?
    Solution
    Black soils are mineral soils which have a black surface horizon, enriched with organic carbon that is at least 25 cm deep. Black soils are made up of volcanic rocks and lava-flow. It is concentrated over Deccan Lava tracts which include parts of Maharashtra, Chhattisgarh, Madhya Pradesh, Gujarat, Andhra Pradesh and Tamil Nadu.
  • Question 13
    1 / -0
    Which of the following statements is/are correct?

    a. Arid soils range from red to brown in colour.
    b. Arid soils are generally sandy in texture and saline in nature.
    Solution
    Arid soils are characteristically developed in western Rajasthan, which exhibits characteristic arid topography. They are generally sandy to gravelly in texture and have a high percentage of soluble salts. Arid soils range from red to brown in colour. These soils are very infertile, but with proper fertilizers and irrigation, the drought resistant and salt tolerant dry crops such as barley, cotton, wheat, millets, maize, pulses, etc. can be grown. After proper irrigation, these soil become cultivable as has been in the case of western Rajasthan.
  • Question 14
    1 / -0
    Which of the following statements is/are incorrect?

    a. The processes of soil formation and erosion go on simultaneously.
    b. The running water cuts through the clayey soils and makes deep channels as valleys.
    c. Shelter belts have contributed significantly to the stabilisation of deserts in western India.
    Solution
    The soil forming processes and the erosional processes of running water and wind go on simultaneously. But generally, there is a balance between these two processes. The rate of removal of fine particles from the surface is the same as the rate of addition of particles to the soil layer. A gully is a land-form made by running water, eroding sharply into soil, usually on a hillside. Gullies resemble small valleys or large ditches. Planting lines of trees to create shelter also checks the soil erosion. Rows of such trees are called Shelter Belts. These shelter belts have contributed significantly to the stabilisation of sand dunes and in stabilising the desert in western India.
  • Question 15
    1 / -0
    Resources can be classified on the basis of ownership. Which of the following resources is/are community owned?
    Solution
    Based on ownership the resources are classified as individual, community, national and international resources. The community owned resource is a type of a resource in which all the members in the resource can own the resource. Everyone in the community can get benefit out of the resource. It is a type of a public resource in which everyone can use it and be benefited out of it. Public Park is an example of community-owned resource.
