d) They can shed their leaves in a specific season to conserve energy.

10. Analyze the given Assertion (A) and Reason (R).

Reason (R): The Taiga region has extensive forests of softwood trees like Pine and Fir, which are ideal for making paper pulp.

a) A is false, but R is true.

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) Both A and R are true, and R is the correct explanation of A.

11. Read the following statements and identify the INCORRECT one.

a) 'Malocas' are large community houses with steep roofs, found in the Amazon rainforest.

Correct Answers

• Question 1: a) (i)-(y)-(r), (ii)-(x)-(q), (iii)-(z)-(p) (Equatorial-Pygmies-Maloca, Tundra-Inuits-Igloo, Desert-Tuaregs-Oasis)
• Question 2: a) Both A and R are true, and R is the correct explanation of A. (Convectional rainfall process)
• Question 3: c) Equatorial → Hot Desert → Taiga → Tundra (Correct latitudinal sequence north from the equator)
• Question 4: c) Only I and III are true. (Statement II is false; Mahogany is an equatorial tree)
• Question 5: b) The consistent high angle of the sun's rays throughout the year. (This leads to consistently high temperatures)
• Question 6: a) Both A and R are true, and R is the correct explanation of A. (Offshore trade winds cause aridity on western continental margins)
• Question 7: b) Statement I is true, but Statement II is false. (Igloos are snow houses. Tupiks are skin tents for *summer*, not winter)
• Question 8: a) Taiga has softwood coniferous trees, while the Equatorial region has hardwood evergreen trees. (A key distinction between the two biomes)
• Question 9: b) They are adapted to survive with very little water in arid conditions. (This is the definition of xerophytes, like cacti)
• Question 10: d) Both A and R are true, and R is the correct explanation of A. (Softwood forests are the resource base for lumbering in the Taiga)
• Question 11: c) Mosses and lichens are the dominant flora in the Taiga coniferous forests. (Incorrect. Mosses/lichens are Tundra flora; Taiga has coniferous trees)
• Question 12: c) (i)-(y)-(q), (ii)-(x)-(r), (iii)-(z)-(p) (Polar Bear-Tundra-Blubber, Camel-Desert-Hump, Orangutan-Equatorial-Arboreal)
• Question 13: c) A layer of soil, rock, or sediment that is frozen for more than two consecutive years. (The definition of permafrost)
• Question 14: c) Oases are the only places with a reliable source of water, which is essential for life and agriculture. (Water is the primary limiting factor in a desert)
• Question 15: a) Only I and II are true. (Statement III is false; Kayaks/Umiaks are Inuit/Tundra boats, not Taiga)
