41: Consider the following statements:
1. Longitude of Jabalpur's location is between those of Indore and Bhopal
2. Latitude of Aurangabad's location is between those of Vadodara and Pune
3. Bangalore is situated more southward than Chennai.
Which of these statements is/are?
(a) 1 and 3
(b) Only 2
(c) 2 and 3
(d) 1, 2 and 3
42: Consider the following ecosystems:
1. Taiga
2. Tropical evergreen
3. Tropical deciduous
4. Tundra
The correct sequence in decreasing order of the albedo values of these ecosystems is
(a) 1, 4, 3, 2
(b) 4, 1, 2, 3
(c) 4, 1, 3, 2
(d) 1, 4, 2, 3
Explanation:
The earth's average albedo is 34%. But it varies according to the texture and colour of the surface. For fresh snow, the albedo is 85%, for forests, it is 5 - 10%. Accordingly, the order is Tundra - Taiga - Tropical evergreen - Tropical deciduous.
