Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → A-II, B-IV, C-III, D-I
(A) Contour ploughing — this matches (II) Ploughing along the contour lines to slow down the flow of water down the slopes. Slower water carries away less soil.
(B) Terrace cultivation — this matches (IV) Steps cut out on the hill slopes. The terraces hold back the soil; the western and central Himalayas have well-developed terrace farming.
(C) Strip cropping — this matches (III) Strips of grass left to grow between the crops in large fields. The strips break up the force of the wind.
(D) Shelter belts — this matches (I) Rows of trees planted to give shelter from the wind. They have helped to fix the sand dunes and stabilise the desert in western India.
