Challenge Prelims V1.0 – Day 21 – GS Paper (Geography)

1. How many of the following conditions aids in the growth of Tropical Evergreen forests in India?

1. Topography of the western slope of the Western Ghats
2. Warm and humid areas with an annual precipitation of over 200 cm
3. Mean annual temperature above 35 degrees Celsius.

Select the correct answer using the code given below.

2. This forest covers vast areas of the country, where rainfall ranges between 70 -100 cm. In the higher rainfall regions of the Peninsular plateau and the northern Indian plain, these forests have a parkland landscape with open stretches in which teak and other trees interspersed with patches of grass are common. As the dry season begins, the trees shed their leaves entirely and the forest appears like a vast grassland with naked trees. Tendu, palas, amaltas, bel, khair, axlewood, etc. are the common trees of these forests.

Which of the following types of forests is being described in the above given passage?

3. How many of the following can be found in the vegetation cover of the Himalayan ranges?

1. Deciduous forests
2. Montane Wet Temperate Forests
3. Evergreen broad leaf trees
4. Temperate grasslands
5. Alpine forests

Select the correct answer using the code given below.

4. Classified as ‘Southern Montane Wet Temperate Forest’, these are found in the upper reaches of the Nilgiris, Anamalais, Palni hills, Kalakadu, Mundanthurai and Kanyakumari in the states of Tamil Nadu and Kerala. The introduction of alien plant species and frequent fires have threatened their existence. Recently, the forest type has been in the news due to the issue of its classification.

9. This soil develops on crystalline igneous rocks in areas of low rainfall in the southern and eastern parts of the Deccan Plateau. They are normally fertile, whereas in dry upland areas the soil has poor fertility due to coarse-grained structure. They are generally poor in humus, phosphorus, and nitrogen.

The above-mentioned paragraph refers to which of the following soils?

How many of the statements given above is/are correct?

11. With reference to the alluvial soils of India, consider the following statements:

1. They are depositional soils, transported and deposited by rivers and streams.
2. They are generally rich in phosphorus but poor in potash.

Which of the statements given above is/are not correct?

12. With reference to soils, consider the following pairs:

Soil: Characteristics

1. Regosol: a regular supply of sediments
2. Lithosol: eroded soil on the steep slopes
3. Vertisol: dry and loose dune sands

How many pairs given above are correctly matched?

13. Which of the following statements regarding the laterite soils of India is correct?

14. These types of soils constitute about 10 to 40% of the organic matter and also a reasonable number of soluble salts. They are low in phosphate and potash content. They are found in the Almora district of Uttarakhand, and also a few districts of Kerala.
