The 'Agricultural Population Density' is referred to as the ratio of the :

  1. A.Total population to Net cultivable land
  2. B.Agricultural population to Gross cropped area
  3. C.Total population to Total reported land
  4. D.Total agricultural population to Net cultivable land

Correct answer

D. Total agricultural population to Net cultivable land

Explanation

The correct answer is D, Total agricultural population to Net cultivable land. Agricultural density measures how many farm people depend on each unit of land that can actually be farmed.

Geographers use three densities. Arithmetic density divides the total population by the total area. Physiological density divides the total population by the net cultivated area. Agricultural density divides only the agricultural population, that is cultivators and agricultural labourers with their families, by the net cultivable area. A high agricultural density shows heavy pressure of farm workers on limited land, a common feature of the Ganga plains.

A is wrong because total population over net cultivable land is physiological density. B is wrong because gross cropped area counts land sown more than once several times and is not the base used. C is wrong because total population over total area is the ordinary arithmetic density.

Exam tip: physiological density uses total population, agricultural density uses only the agricultural population, both over net cultivable area.

Which of the following statements is/are correct? 1. Himalayan rivers have their origin in the snow-covered areas, hence are dry in winter season. 2. Rivers of the Peninsular Plateau have reached maturity. 3. Himalayan rivers depict all the three stages of normal cycle of erosion. Select the correct answer using the code given below.

  1. A.2 only
  2. B.1 and 3 only
  3. C.2 and 3 only
  4. D.1, 2 and 3
Show answer
Correct answer: C. 2 and 3 only

Himalayan rivers are perennial, so statement 1 is wrong, while statements 2 and 3 are correct. Himalayan rivers such as the Ganga, Indus and Brahmaputra rise from glaciers and snowfields and also get monsoon rain, so they flow all year round, including in winter.

Which of the following statements related to latitude are true? 1. Rainfall, temperature and vegetation vary with latitude. 2. The difference between the longest day and the shortest day increases with latitude. 3. Indira Point is located approximately at 6°45' N latitude. Select the correct answer using the code given below.

  1. A.1 and 2 only
  2. B.1 and 3 only
  3. C.2 and 3 only
  4. D.1, 2 and 3
Show answer
Correct answer: D. 1, 2 and 3

All three statements about latitude are true. Latitude decides how directly the Sun's rays strike a place, so temperature, rainfall and the type of vegetation change from the equator towards the poles, from hot, wet rainforests to cold tundra.

  2. B.2 and 3
  3. C.1, 2 and 4
  4. D.2 and 4 only
Show answer
Correct answer: C. 1, 2 and 4

Tso Kar, Pangong Tso and Tso Moriri are high-altitude lakes of Ladakh, while Tsomgo lies in Sikkim. Pangong Tso, at about 4,350 metres, is a long, narrow lake that stretches from Ladakh into Tibet, and most of its length lies on the Chinese side.
