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. What are the main criteria of dividing major natural regions of the world?
[A] Temperature, rain fall and vegetation
[B] Latitudes and Longitudes
[C] Atmospheric Pressure and Winds
[D] All of them
Show Answer
Correct Answer: A [ Temperature, rain fall and vegetation ]
Notes:
The main criteria of dividing major natural regions of the world are Temperature, rainfall and vegetation. They play a major role as they vary with the latitude and they became the main criteria.
2. A cataclysmic nuclear explosion caused by the accretion of hydrogen onto the surface of a white dwarf star, would be termed as ___?
[A] Nova
[B] Nebula
[C] Neutron star
[D] Pulsar
Show Answer
Correct Answer: A [Nova]
Notes:
A nova is a transient astronomical event that causes the sudden appearance of a bright, apparently “new” star, that slowly fades over time. It is caused by a nuclear explosion, caused by the accretion of hydrogen onto the surface of a white dwarf.

[A] Nile River
[B] Niger River
[C] Gambia River
[D] Yobbe River
Show Answer
Correct Answer: A [Nile River]
Notes:
Nile is considered the Father of African Rivers. It is Stretching for approximately 6,695 km across 10 different countries, the Nile River is the longest river in the world.
5. Who discovered Cosmic Rays?
[A] Henri Becquerel
[B] Theodor Wulf
[C] Robert Millikan
[D] Bruno Rossi
Show Answer
Correct Answer: C [Robert Millikan]
Notes:The term “cosmic rays” was coined by the Austrian physicist Victor Francis Hess in 1912. Hess was awarded the Nobel Prize in Physics in 1936 for his discovery of cosmic rays.
Cosmic rays are high-energy particles that travel through space and reach the Earth’s atmosphere. They are believed to be made up of protons, electrons, and atomic nuclei, and they can have energies that are millions or billions of times greater than those of particles produced by particle accelerators on Earth.
Hess discovered cosmic rays while conducting experiments in which he flew high-altitude balloon flights to measure the radiation levels at different altitudes. He found that the radiation levels increased with altitude, leading him to conclude that the radiation was coming from outer space and not from the Earth’s surface. He named these high-energy particles “cosmic rays” because they seemed to be coming from the cosmos.
6. What is rank of Earth in Solar system in terms of mean Radius?
[A] 1st
[B] 3rd
[C] 5th
[D] 7th
Show Answer
Correct Answer: C [5th]
Notes:
The rank of earth in terms of mean radius is 5. Jupiter, Saturn and Uranus are top 3 countries with mean radius.
7. Taiga is located at southern latitudes than Tundra, still the extreme minimum temperatures have been recorded in Taiga. What is / are the reasons behind the same?
[A] Because winters of Taiga get colder due to Polar winds
[B] Because Tundra is near to Arctic Ocean
[C] Because Taiga has clearer skies in comparison to Tundra
[D] All of above reasons.
Show Answer
Correct Answer: B [Because Tundra is near to Arctic Ocean]
Notes:
In the above question, the correct answer is B. In winter, there are long periods of frozen Ice on Polar Tundra, yet the Arctic Ocean contains enough heat to tweak the temperature a little bit. This is the reason that lowest reliably recorded temperatures in the Northern Hemisphere were recorded in the taiga of northeastern Russia.
8. Which of the following winds is also known as “ice-eater”?
[A] Harmattan
[B] Chinook
[C] Sirocco
[D] Mistral
Show Answer
Correct Answer: B [Chinook]
Notes:
Chinook is basically warm winds originally meant a warming wind from the ocean into the interior regions of the Pacific Northwest of the USA. Foehn is a type of dry, warm, down-slope wind that occurs in the lee (downwind side) of a mountain range. Harmattan is a dry and dusty north-easterly trade wind which blows from the Sahara Desert over the West African. Mistral is a strong, cold, north-westerly wind that blows from southern France into the Gulf of Lion in the northern Mediterranean. Sirocco is a Mediterranean wind that comes from the Sahara and can reach hurricane speeds in North Africa and Southern Europe.
9. Neap tides are produced in the first and third quarters of the Moon. Which of the following is the situation for Neap tides to occur?
[A] The Moon and the Sun are in conjunction with the other planets
[B] The Moon and the Sun are in opposition with each other
[C] The attractions of the Sun and the Moon are at right angles to each other
[D] The Moon and the Sun are in quadrant position to each other
Show Answer
Correct Answer: C [The attractions of the Sun and the Moon are at right angles to each other]
Notes:
A tide in which the difference between high and low tide is the least. Neap tides occur twice a month when the Sun and Moon are at right angles to the Earth. When this is the case, their total gravitational pull on the Earth’s water is weakened because it comes from two different directions. Compare spring tide.
10. Which one of the following winds is not a planetary wind?
[A] Trade
[B] Westerly
[C] Polar Easterly
[D] Monsoon
Show Answer
Correct Answer: D [Monsoon]
Notes:
Planetary winds are also known as permanent winds. The trade winds, the Easterlies and the Westerlies are known as planetary or permanent winds as they continuously blow throughout the year. These winds always blow in a particular direction. Monsoon is not a planetary wind.
