31. Which among the following groups in Koeppen’s climate classification is used to designate Desert Climate?
Show Answer
Correct Answer: D [W]
Notes:
The Koeppen climate classification system recognizes five major climatic types and each type is designated by a capital letter- A, B, C, D, E, and H.
The capital letters S and W are employed to designate the two subdivisions of dry climate:
S – Semi arid or Steppe
W – arid or desert
32. Which ocean is the coldest among all oceans in the world?
[A] Southern Ocean
[B] Pacific Ocean
[C] Arctic Ocean
[D] Atlantic Ocean
Show Answer
Correct Answer: C [Arctic Ocean ]
Notes:
The Arctic Ocean is the smallest and shallowest of the world’s five major oceans. It is also known as the coldest of all the oceans.
33. Who among the following has given the classification of Ocean Deposits?
[A] F. Hoyle
[B] Alexander Humboldt
[C] Sir John Murray
[D] Jeans Jaques
Show Answer
Correct Answer: C [Sir John Murray]
Notes:
Sir John Murray has classified the ocean deposits into two broad categories viz.:
terrigenous deposits – Terrigenous deposits are found mainly on the continental shelves and slopes.
pelagic deposits – pelagic deposits predominate on the deep sea floor.
34. Which among the following statements is/are correct about Ocean deposits?
- Terrigenous deposits are found mostly at shallower depths and includes deposits of mud, sand, gravel, and volcanic materials, derived from denudation of continental rocks.
- Terrigenous deposits cover about 75.5 per cent of ocean areas in the form of many types of oozes.
Select the correct code from the options given below:
[A] Only 1
[B] Only 2
[C] Both 1 & 2
[D] Neither 1 & 2
Show Answer
Correct Answer: A [Only 1]
Notes:
Terrigenous deposits are found mostly at shallower depths and includes deposits of mud, sand, gravel, and volcanic materials, derived from denudation of continental rocks.
Pelagic deposits consist of organic material in the form of marine plants and animals as well as inorganic material.
They cover about 75.5 per cent of ocean areas in the form of many types of oozes in a sporadic mix in most cases with other types of ocean deposits.
35. Which among the following pairs of Mud is/are correctly matched?
- Green Mud – It contains 35% of calcium carbonate.
- Blue Mud – It includes the materials derived through the disintegration of rocks rich in Iron Sulphide and organic elements.
- Red Mud – The sediments derived through the communition of rocks rich in iron oxides from red mud.
Select the correct code from the options given below:
[A] Only 2 & 3
[B] Only 1 & 3
[C] Only 1 & 2
[D] 1, 2 & 3
Show Answer
Correct Answer: A [Only 2 & 3]
Notes:
Murray has divided mud into 3 types on the basis of colour:
Red Mud – The reddish colour is mainly due to dominance of iron content.
Blue Mud -It contains 35% of calcium carbonate. It includes the materials derived through the disintegration of rocks rich in Iron Sulphide and organic elements.
Green Mud – formed due to chemical weathering wherein the colour of blue mud is changed to green mud due to reaction of sea water.
36. Which among the following statements is/are correct about Waves?
- Waves are nothing but the oscillatory movements that result in the rise and fall of water surface.
- They are a vertical movement of waters and are different from movements of ocean water caused by meteorological effects like the winds and atmospheric pressure changes.
Select the correct code from the options given below:
[A] Only 1
[B] Only 2
[C] Both 1 & 2
[D] Neither 1 & 2
Show Answer
Correct Answer: A [Only 1]
Notes:
Waves are nothing but the oscillatory movements that result in the rise and fall of water surface.
Waves are a kind of horizontal movements of the ocean water.
Waves and the ocean currents are horizontal movements of ocean waters while the tide is a kind of vertical movement of the ocean water.
37. What is the point in the Moon’s orbit that is farthest to the Earth called?
[A] Apogee
[B] Perigee
[C] Aphelion
[D] Perihelion
Show Answer
Correct Answer: A [Apogee]
Notes:
Apogee: When the moon’s orbit is farthest from the earth, it is called as apogee. Tidal ranges will be much less than the average during this period.
38. What is the general distribution of winds in the lower atmosphere called?
[A] Cyclones
[B] Planetary winds
[C] Jet streams
[D] Loo
Show Answer
Correct Answer: B [Planetary winds]
Notes:
The general distribution of winds in the lower atmosphere is called as Planetary winds.
The planetary winds are permanent winds that blow from one pressure belt to the other. Accordingly, they have been divided into – Tradewinds, Westerlies and Polar Easterlies
39. Which one of the following types of economic activities dominates in all rural settlement?
[A] Primary
[B] Secondary
[C] Tertiary
[D] Quaternary
Show Answer
Correct Answer: A [Primary]
Notes:
Rural settlements are most closely and generally directly related to land. These settlements are dominated by primary activities such as agriculture, animal husbandary, fishing etc. The settlements size is relatively small.
40. What type of farming is practiced in areas where there is no dearth of rainwater for the production of crops?
[A] Precision Farming
[B] Irrigation Farming
[C] Humid Farming
[D] Dry Farming
Show Answer
Correct Answer: C [Humid Farming ]
Notes:
Humid farming – This type of farming is practiced in areas where there is no dearth of rainwater for the production of crops.
Problems of water logging and drainage and soil erosion are present in the heavy rainfall areas.
