Question

Consider the following statements and select the option which correctly identifies true (T) and false (F) ones.
(i) North-East India receives very little rain throughout the year, so we can say that climate in North-East India is hot and dry.
(ii) Thick layer of subcutaneous fat, thick skin and a dense feather cover in polar birds like penguins protect them from severe cold weather.
(iii) Polar animals need to conserve water due to water scarcity.
(iv) As we move higher up from sea level, temperature decreases.

• A. (i)F (ii)F (iii)T (iv)T
• B. (i)F (ii)T (iii)F (iv)T
• C. (i)F (ii)F (iii)T (iv)F
• D. (i)T (ii)T (iii)F (iv)T

Answer 1

Answer: (B)

(i)F (ii)T (iii)F (iv)T

• North-East India receives rain for the major part of the year. Therefore, the climate of the North-East is wet.
• Polar animals do not need to conserve water in their bodies as they are living in a cold environment.
• Yes, a thick layer of subcutaneous fat, thick skin, and a dense feather cover in polar birds like penguins protect them from severe cold weather.
  
• As we move higher from sea level, the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands), and the temperature decreases.
  

So the correct answer is option B.
