World & Physical Geography MCQs
World Geography Multiple Choice Questions (MCQs) Quiz for State and UPSC Civil Services Examinations. Objective Questions on Physical Geography and World Geography for competitive examinations.
1. Geo centric model of solar system was proposed by:
[A] Copernicus
[B] Ptolemy
[C] Aristotle
[D] Strabo
Show Answer
Correct Answer: B [Ptolemy]
Notes:
Geo-centric theory of solar system was proposed by Ptolemy 2000 years ago. This theory states that all celestial objects, stars, the sun and the planets, all revolved around the earth.
2. After the sun, what is the nearest star to the earth?
[A] Alpha Centauri
[B] Orion
[C] Ursa Major
[D] Sirius
Show Answer
Correct Answer: A [Alpha Centauri]
Notes:
Following the sun, Alpha Centauri is the closest star to Earth, located approximately 4.367 light years away. It’s a star system consisting of three stars: Alpha Centauri A, Alpha Centauri B, and Proxima Centauri.
3. Which is the most abundant metal in the Earth’s crust?
[A] Silicon
[B] Iron
[C] Aluminium
[D] Zinc
Show Answer
Correct Answer: C [Aluminium]
Notes:
Aluminum is the most abundant metal in the Earth’s crust, making up about 8.1% of the crust. However, it’s rarely found in its pure form in nature. Instead, it’s usually found combined with other elements in minerals like bauxite and cryolite. Two common aluminum compounds are alum and aluminum oxide. The most abundant non-metal in the Earth’s crust is oxygen, which makes up about 46% of the crust.
4. Which among the following country derives its name from a latitude?
[A] Canary Islands
[B] Canada
[C] Australia
[D] Ecuador
Show Answer
Correct Answer: D [Ecuador]
Notes:
The name “Ecuador” originates from the Latin word “aequator,” which means “equal”. It refers to the country’s geographical position straddling the equator, which bisects the nation into two nearly equal halves. This uniqueness has been reflected in its name to denote its location. In addition to this, Ecuador is the only country in the world to be named after a geographical feature.
5. At which of the following places water would boil at lowest temperature?
[A] Delhi
[B] Shimla
[C] Kochi
[D] Jodhpur
Show Answer
Correct Answer: B [Shimla]
Notes:
Shimla is the place among the options where water boils at low temperature. At higher altitudes, air pressure is lower. When atmospheric pressure is lower, such as at a higher altitude, it takes less energy to bring water to the boiling point. Less energy means less heat, which means water will boil at a lower temperature at a higher altitude.
6. Which among the following is known as world’s most abundant fine-grained extrusive rock?
[A] Granite
[B] Basalt
[C] Feldspar
[D] Quartzite
Show Answer
Correct Answer: B [Basalt]
Notes:
Basalt is known as world’s most abundant fine-grained extrusive rock.
7. What will happen to the population of plants and animals, when a person moves from poles to the equator?
[A] Increase
[B] Decrease
[C] Remain unchanged
[D] Not show any consistent behavior
Show Answer
Correct Answer: A [Increase]
Notes:
Moving to equator results in less disturbance for wildlife in that area. Much of the biodiversity around the equator is in the rainforest. As stated before, geographic isolation drove speciation around the equator, increasing the overall uniqueness and amount of species.
8. Which is the northern-most coral atoll in the world?
[A] Kure Atoll
[B] Great Chagos Bank
[C] Reed Bank
[D] Rosalind Bank
Show Answer
Correct Answer: A [Kure Atoll]

[B] Engilchek Glacier
[C] Biafo Glacier
[D] Byrd Glacier
Show Answer
Correct Answer: B [Engilchek Glacier]
Notes:
Engilchek Glacier is the largest and the fastest moving glacier in Kyrgyzstan. It is located in the Central Tian Shan Mountains of Issyk-Kul region of northeastern Kyrgyzstan. Also, it is the sixth longest non polar glacier in the world.
10. Who among the following proposed that the universe is in the steady state?
[A] Laplace
[B] Immanuel Kant
[C] Edwin Hubble
[D] Fred Hoyle
Show Answer
Correct Answer: D [Fred Hoyle ]
