15. Given below are two statements. One is labelled as Assertion and other as Reason: [U.P.P.C.S.(MAINS) 2003]

Assertion (A) : The frequency of landslides has increased and other as Reason:
Reason (R) : There has been large scale mining in the Himalayan in recent years.
In the context of the above which one of the following is correct:
Code:

(a) Both (A) and (R) are true, and (R) is the correct explanation of (A)
(b) Both (A) and (R) are true, but (R) is not the correct explanation of (A)
(c) (A) is true but (R) is false
(d) (A) is false but (R) is true

Correct Answer: (a) Both (A) and (R) are true, and (R) is the correct explanation of (A)

Solution:The frequency of landslides has increased in the Himalayas. Its root cause is the increased frequency of earthquake as well as manual activities such as the construction of roads and dams. There has been large scale mining done for the construction of road, dams, and minerals in the Himalayas in recent years. that is why the frequency of landslides has increased in the Himalayas. Thus, both (A) and (R) are true, and (R) is the correct explanation of (A).

16. Cyclones are more frequent in the coastal areas of Bay of Bengal, because- [M.P.P.C.S.(PRE) 1996]

(a) High temperatures in the Bay of Bengal
(b) Water in the Bay of Bengal has chemicals which help in the formation of cyclones
(c) Long chain of the island of Andaman and Nicobar acts as launching pad for cyclones
(d) The conical shape of Bay of Bengal funnels cyclones North wards when they are formed in the sea

Correct Answer: (a) High temperatures in the Bay of Bengal

Solution:A cyclone is a large scale air mass that rotates around a strong centre of low pressure. They are usually characterized by inward spiralling winds that rotate counterclockwise in the northern hemisphere and clockwise in the southern hemisphere.
The cyclones affect the Bay of Bengal and Arabian sea. More cyclones get formed in the Bay of Bengal due to low pressure, generated by high temperature. These cyclones move in anticlockwise direction. There are two definite seasons of tropical cyclones in the North Indian Ocean. One is from May to June and the other from mid-September to mid-December. May, June, October, and November are known for severe storms. The entire east coast from Odisha to Tamil Nadu is vulnerable to cyclones with varying frequency and intensity. Hence, Statement (a) is correct.

17. Assertion (A): East coast is most prone to cyclones than western coast. [U.P.P.C.S.(Pre) 2003]

Reason (R) : Easter coast of India lies in the zone of north-east trade winds.
In the context of above statements, which of the following is correct?

(a) (A) and (R) both are true, and (R) is correct explanation of (A).
(b) (A) and (R) both are true, but (R) is not the correct explanation of (A).
(c) (A) is true, but (R) is false
(d) (R) is true, but (A) is false.

Correct Answer: (b) (A) and (R) both are true, but (R) is not the correct explanation of (A).

Solution:Eastern coast is more prone to cyclone than western coast as cyclones originating in the Bay of Bengal move anticlockwise direction and affect whole east coast. Hence, the statement (A) is correct. Eastern coast of India lies in zone of northeast trade winds. Thus, both (A) and (R) are
true and (R) is not the correct explanation of (A).

18. Assertion (A): The Koyna region of Maharashtra is likely to become more earthquake- prone in near future. [U.P.P.C.S.(Pre) 2001]

Reason (R) The Koyna dam is located on an old fault-plane which may get activated more frequently with changes in water-level in Koyna reservoir.

Select the correct answer using the code given below:

Code:

(a) Both (A) and (R) are true, and (R) is the correct explanation of (A).
(b) Both (A) and (R) are true, but (R) is not a correct explanation of (A)
(c) (A) is true, but (R) is false.
(d) (A) is false, but (R) is true.

Correct Answer: (a) Both (A) and (R) are true, and (R) is the correct explanation of (A).

Solution:According to Geologists, the Koyna dam is located on an old fault plain which may get activated more frequently with changes in the water level in Koyna reservoir. Koyna region of Maharashtra may thus become more earthquake prone in the near future.

19. Which among the following states faces a maximum natural disaster? [U.P. Lower Sub. (Spl.)(Pre) 2002]

(a) Andhra Pradesh
(b) Odisha
(c) Bihar
