Q521. In which of the following climatic conditions, the problem of salinization in farmland due to irrigation is the most prominent?
π 1 viewsSalinization of farmland from irrigation is worst when there is high evaporation and little rainfall. Dry, hot, and windy conditions accelerate evaporation from the soil surface, causing salts to accumulate as irrigation water evaporates and leaching is limited. In such climates, salts remain near the root zone, harming crops. The other options have less evaporation or more rainfall, which helps leach salts away or dilute them; hence they are less prone to severe salinization compared with dry, hot, and windy conditions.
In arid and semi-arid regions, soil salinity often increases due to high evapotranspiration surpassing precipitation and inadequate drainage.
Salinization is most severe when evaporation is high and leaching is minimal (dry, hot, windy climates).
Q522. Which of the following combinations of the Ramsar Sites and the States of North-East India, where they are located, are correct?
(i) Rudrasagar Lake - Assam
(ii) Loktak Lake - Manipur
(iii) Deepor Beel - Assam
(iv) Pala Wetlands - Meghalaya
Select the correct answer using the codes given below.
Ramsar sites and their state locations: Loktak Lake is in Manipur and Deepor Beel is in Assam, making (ii) and (iii) correct. Rudrasagar Lake is in Tripura, not Assam, so (i) is incorrect. Pala Wetlands are not in Meghalaya; thus (iv) is incorrect. Therefore, only the combination (ii) and (iii) matches the actual locations.
Loktak Lake is the largest freshwater lake in Northeast India and is known for the phumdis floating over its surface.
Loktak (Manipur) and Deepor Beel (Assam) are Ramsar sitesβothers are located in different states.
