[B] Venezuela
[C] Belize
[D] Chile
Show Answer
Correct Answer: C [Belize]
Notes:
The Maya Mountains are a mountain range located in Belize. The highest peak of this range is Doyle’s Delight which is 1124 metres above sea level. This mountain range houses Cockscomb Basin Wildlife Sanctuary. It is a location of a number of Mayan ruin sites. These mountains are made of the Paleozoic era of granite and sediments.
22. Okavango Delta is located in which country?
[A] Botswana
[B] Sudan
[C] Ethiopia
[D] Uganda
Show Answer
Correct Answer: A [Botswana]
Notes:
Okavango Delta is located in Botswana. It is both UNESCO World Heritage Site and Ramsar Wetland. River Okavango forms this delta. It is an endorheic basin of Kalahari. Moremi Game Reserve is located on the eastern side of the delta. Okavango Delta is one of the seven natural wonders of Africa. After the flooding season of this delta, a special type of land will be formed due to the moisture presence called Molapo.
23. Which is the highest peak in the Andes mountain range?
[A] Mt. Mitchell
[B] Mt. Aconcagua
[C] Mt. Blanc
[D] Mt. Elbert
Show Answer
Correct Answer: B [Mt. Aconcagua]
Notes:
The Andes Mountains in South America, are the longest mountain chain in the world. Mt. Aconcagua is the highest peak in the Andes.
24. What are low clouds also known as?
[A] Altocumulus
[B] Cirrus
[C] Cirrostratus
[D] Stratus
Show Answer
Correct Answer: D [Stratus]
Notes:
Low clouds lie at around 2000 metres above ground. Low clouds are also known as Stratus Clouds. They usually look like a huge grey blanket that hangs low in the sky that resembles fog. If these clouds are warm it means rain and if it is cold it snows.
25. 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.
26. Which is the only ocean which is almost totally bounded by subduction zones?
[A] Indian
[B] Atlantic
[C] Arctic
[D] Pacific
Show Answer
Correct Answer: D [Pacific]
Notes:
The Pacific Ring of Fire is the world’s foremost belt of explosive volcanism. The Pacific Ocean is the only ocean which is almost totally bounded by subduction zones. Only the Antarctic and Australian coasts have no nearby subduction zones.
27. Which among the following factors lead to the cooling of the ocean water?
- Exchange of heat between the sea and the atmosphere
- Evaporation
- Convectional Currents
Select the correct code from the options given below:
[A] Only 1
[B] Only 3
[C] Only 1 & 2
[D] 1, 2 & 3
Show Answer
Correct Answer: C [Only 1 & 2]
Notes:
Following factors lead to the cooling of the ocean:
Back radiation in the form of long wave radiation, from the sea surface.
Exchange of heat between the sea and the atmosphere if there is temperature difference.
Evaporation: Heat is lost in the form of latent heat of evaporation
The Convectional Currents present in the earth’s interior heat the waters at the depth very fast. Thus leading to the increase in the temperature of the oceans.
28. 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
29. Which among the following statements is/are correct about La Nina?
- The literal meaning of the term La Nina is a Christ child.
- During the occurrence of this condition sea surface temperature in the central and western Pacific rises above the normal.
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: D [Neither 1 & 2]
Notes:
The La Nina presents a situation that can be described as roughly opposite of the El Nino. The literal meaning of the term La Nina is a girl child. During the occurrence of this condition sea surface temperature in the central and western Pacific falls below the normal and this happens due to the South Pacific Sub-tropical High becoming exceptionally strong during the summer season.
30. Which theory says that there was a near-extinction event for early humans about 70,000 years ago?
[A] Toba catastrophe theory
[B] Turnover pulse hypothesis
[C] Red Queen hypothesis
[D] Aridity hypothesis
Show Answer
Correct Answer: A [Toba catastrophe theory]
Notes:
Evolution involves the gradual changes from simple to more complex forms. Humans are believed to have developed from simpler forms.
Toba catastrophe theory – The theory that there was a near-extinction event for early humans about 70,000 years ago.
