513: Consider the map given below :
Of the four-shaded areas in the map, that which is characterised by hot dry summers, mild and moist winters and seasonal reversal of winds is the area labelled
(a) 1
(b) 2
(c) 3
(d) 4
Explanation:
The hot dry summers, mild and moist winters and seasonal reversal of winds is the charateristic of Mediterranean type of climate. found between 30 degree - 45 degree latitude in both the hemispheres on the western side of each continent. So in the given map 2, 3, 4 are in eastern side. Only 1 which is indicated for California (U.S.A.) region is possessing that type of climate.
514: Consider the following pairs:
Wildlife:
1. Blue-finned Mahseer
2. Irrawaddy Dolphin
3. Rusty-spotted Cat
Naturally found in
1. Cauvery River
2. Chambal River
3. Eastern Ghats
Which of the pairs given correctly matched?
(a) 1 and 2 only
(b) 2 and 3 only
(c) 1 and 3 only
(d) 1, 2 and 3
Explanation:
The Western Ghats region is famous for freshwater biodiversity. Mahseer, belonging to the genus Tor, is considered a prized sports fish of great cultural value.In the Cauvery the Mahseer community comprises two varietiesa "blue-finned" fish and an "orange-finned, hump-backed" one. Hence, pair 1 is correctly matched. Irrawaddy dolphins are distributed in shallow, near-shore tropical and subtropical marine waters. They are primarily found in estuaries and semi-enclosed water bodies such as bays and sounds, usually close to mangrove forests. Hence, pair 2 is NOT correctly matched. Forests of the Eastern Ghats are home to some endangered and lesser-known mammal species like the Fishing Cat, Rusty Spotted Cat, Indian Pangolin etc. Hence, pair 3 is correctly matched.
