Question 1 of 5

- Most of the cyclones that hit India originate in the Bay of Bengal, rather than the Arabian Sea.
- Arabian Sea cyclones are also relatively weak compared to those emerging in the Bay of Bengal.
Which of the above statements is/are correct?
Correct
Solution: c)
Though cyclones are common in the month of June, very few of them originate in the Arabian Sea. Most of them are found in the Bay of Bengal. In the last 120 years for which records are available, just about 14% of all cyclonic storms, and 23% of severe cyclones, around India have occurred in the Arabian Sea. Arabian Sea cyclones are also relatively weak compared to those emerging in the Bay of Bengal.

Question 2 of 5
2. Question
A tropical cyclone is classified as making landfall when
- The centre of the storm moves across the coast
- The heat from condensation of vapour nuclei reaches its peak levels.
Select the correct answer code:
Correct
Solution: a)
A Landfall is the intersection of the center of a tropical cyclone with a coastline. Typically, in strong tropical cyclones, a landfall occurs when the eye of the cyclone moves over land.
When the cyclone makes landfall, it starts to lose speed and energy as it loses its source of both from the warm ocean waters. Therefore, at this point the condensation of the nuclei will drop, and not reach peak levels.

Correct
Solution: c)

Question 5 of 5
5. Question
Why are the western slopes of the Western Ghats covered with thick forests and not the eastern slopes?
- Soil in eastern slope cannot support vegetation due to absence of nutrients.
- Eastern side falls in rain shadow zone
- No protected forests exist on the eastern slopes.
Select the correct answer code:
Correct
Solution: b)
When moisture laden winds cause rainfall in western slopes, upon moving to eastern sides they lose much of their moisture. Rainfall is less, and thus vegetation is less thick at eastern slopes.
Nilgiri Biosphere Reserve extends to Eastern Slopes.
