21. Which among the following conditions is/are favourable for the formation of Cyclone?
- Low sea surface with temperature lower than 27° C.
- Presence of the Coriolis force
- Small variations in the vertical wind speed
- Upper divergence above the sea level system
Select the correct code from the options given below:
[A] Only 1, 2 & 3
[B] Only 2, 3, & 4
[C] Only 1 & 2
[D] 1, 2, 3 & 4
Show Answer
Correct Answer: B [Only 2, 3, & 4]
Notes:
Cyclone is any low-pressure area with winds spiralling inwards.
Conditions Favourable for Tropical Cyclone Formation include:
Large sea surface with temperature higher than 27° C,
Presence of the Coriolis force enough to create a cyclonic vortex,
Small variations in the vertical wind speed,
A pre-existing weak low-pressure area or low-level-cyclonic circulation,
Upper divergence above the sea level system.
22. How many climatic groups did Koeppen recognise?
[A] 20
[B] 10
[C] 5
[D] 2
Show Answer
Correct Answer: C [5]
Notes:
Koeppen’s Classification of climate is the most commonly used classification of climate. He recognized a close relationship between the distribution of vegetation and climate. 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.
23. Which among the following statements is/are correct about the continental shelf?
- It is the extended margin of each continent
- They are the richest fishing grounds in the world.
- They are associated with active volcanoes and strong earthquakes.
Select the correct code from the options given below:
[A] Only 1 & 2
[B] Only 1 & 3
[C] Only 1
[D] 1, 2 & 3
Show Answer
Correct Answer: A [Only 1 & 2]
Notes:
Continental Shelf is the extended margin of each continent occupied by relatively shallow seas and gulfs. It is the shallowest part of the ocean showing an average gradient of 1° or even less.
The shallowness enables sunlight to penetrate through the water, which encourages the growth of minute plants and other microscopic organisms, thus continental shelves are the richest fishing grounds in the world.
The Oceanic Trenches are associated with active volcanoes and strong earthquakes.
24. Which among the following ocean bottom relief indicates the end of the continents?
[A] Continental Shelf
[B] Trenches
[C] Continental Slope
[D] Continental Rise
Show Answer
Correct Answer: C [Continental Slope]
Notes:
The continental slope connects the continental shelf and the ocean basins. It begins where the bottom of the continental shelf sharply drops off into a steep slope. The continental slope boundary indicates the end of the continents.
25. Which ocean is the saltiest of all oceans?
[A] Pacific
[B] Indian
[C] Arctic
[D] Atlantic
Show Answer
Correct Answer: D [Atlantic]
Notes:
Surface waters in the Atlantic have the highest salinity, higher than 37 parts per thousand in some areas.
There is more evaporation than combined rainfall and river runoff into the Atlantic Ocean, maintaining higher salinity than in the other basins.
26. The Bay of Fundy is related to which among the following?
[A] Largest Delta
[B] Highest Tides
[C] Lowest Volcano
[D] Longest Delta
Show Answer
Correct Answer: B [Highest Tides]
Notes:
The periodical rise and fall of the sea level, once or twice a day, mainly due to the attraction of the sun and the moon, is called a tide.
The highest tides in the world occur in the Bay of Fundy in Nova Scotia, Canada.
The tidal bulge is 15 – 16 m.
27. Which among the following is/are warm ocean currents in the Atlantic Ocean?
- Gulf Stream
- Canaries current
- Brazilian current
- Falkland current
- Florida current
Select the correct code from the options given below:
[A] Only 1, 3 & 5
[B] Only 1, 2, 3 & 4
[C] Only 2 & 5
[D] 1, 2, 3, 4 & 5
Show Answer
Correct Answer: A [Only 1, 3 & 5]
Notes:
Warm currents in the Atlantic Ocean:
North Equatorial Current
South Equatorial Current
Brazilian Current
Gulf Stream
Florida Current
28. Which of the following is/are unique characteristics of equatorial forests?
- Presence of tall, closely set trees with crowns forming a continuous canopy.
- Coexistence of a large number of species.
- Presence of numerous varieties of epiphytes.
Select the correct code from the options given below:
[A] Only 1
[B] Only 2 & 3
[C] Only 1 & 3
[D] 1, 2 & 3
Show Answer
Correct Answer: D [1, 2 & 3]
Notes:
The equatorial vegetation comprises a multitude of evergreen trees, e.g. mahogany, ebony, dyewoods etc. All plants struggle upwards (most epiphytes) for sunlight resulting in a peculiar layer arrangement (canopy). High temperature and abundant rainfall support a luxuriant tropical rain forest. In the coastal areas and brackish swamps, mangrove forests thrive.
29. The “Trafalgar Falls” is located in which country?
[A] Brazil
[B] The Bahamas
[C] Dominica

[A] Linear Pattern
[B] Rectangular Pattern
[C] Circular Pattern
[D] Star like Pattern
Show Answer
Correct Answer: A [Linear Pattern]
