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. Who among the following proposed Laws of planetary motion?
[A] Newton
[B] Kepler
[C] Ptolemy
[D] Copernicus
Show Answer
Correct Answer: B [Kepler]
Notes:
Kepler proposed Laws of planetary motion. These three laws describes the behavior of planets in the heliocentric model;
The three laws of Kepler can be stated as follows:
1. Law of orbits: All planets move in elliptical orbits with the Sun situated at one of the foci of the ellipse
2. Law of areas: The line that joins any planet to the sun sweeps equal areas in equal intervals of time.
3. Law of periods: The Square of the time period of revolution of a planet is proportional to the cube of the semi-major axis of the ellipse traced out by the planet. The law of areas can be understood as a consequence of conservation of angular momentum which is valid for any central force.
2. Which of the following rocks are known as Primary rocks?
[A] Igneous Rocks
[B] Metamorphic Rocks
[C] Sedimentary Rocks
[D] None of the above
Show Answer
Correct Answer: A [Igneous Rocks]
Notes:
All the rocks are derived from igneous rocks which are formed by the solidification of hot molten material called magma or lava. Therefore igneous rocks are also called as primary rocks or parent rocks.
3. Chenab River also known as Chandrabhaga forms with the merging of Chandra and Bhaga Rivers near which among the following places?
[A] Leh
[B] Lahaul & Spiti
[C] Sri Nagar
[D] Mithankot (Pakistan)
Show Answer
Correct Answer: B [Lahaul & Spiti]
Notes:
The Chenab River, also known as the Chandrabhaga River, is formed by the merging of the Chandra and Bhaga Rivers at Tandi in the Lahaul Spiti district of Himachal Pradesh. The Chandra and Bhaga Rivers originate from opposite sides of the Baralacha pass at an elevation of 4,891 meters. They meet at Tandi at an elevation of 2,286 meters.
4. Consider the following:
Assertion: Ireland is relatively warm in winter, even though it is close to the Arctic Circle
Reason: Few countries above arctic circle are ice-free during the winter season due to warm waters of Gulf Stream
Which among the following is / are correct statements?
[A] Assertion is true, Reason is incorrect
[B] Assertion is incorrect, Reason is correct
[C] Both Assertion and Reason are correct
[D] Both Assertion and Reason are incorrect
Show Answer
Correct Answer: C [ Both Assertion and Reason are correct]
Notes:
Ireland is relatively warm in winter, even though it is close to the Arctic Circle because of the warm waters of gulf stream. Few countries above arctic circle are ice-free during the winter season due to warm waters of Gulf Stream.
5. Identify the planet with the help of given information:
- The planet is also known as “Earth’s Twin”
- It has the longest day in the solar system
- The poles of this planet are not flattened like other planets
Select the correct answer from options given below:
[A] Mars
[B] Venus
[C] Uranus
[D] Saturn
Show Answer
Correct Answer: B [Venus]
Notes:
Venus is the slowest moving planet in the solar system. Venus has a rotational velocity of just 6.5 km/h compared to Earth’s rational velocity of 1,670 km/h. Due to its slow speed it has not experienced flattening at poles. Mars is also be called “Earth’s Twin” sometimes, but other given features in the question are not for Mars.
6. Which of the following statements is an incorrect statement about Antarctic Circle?
[A] The Sun is visible at local midnight and not visible at local noon at least once a year within the Circle
[B] The position of the Circle is not fixed and it fluctuates due to tidal forces
[C] Days and nights can never be longer than 24 hours inside the Circle
[D] There is no permanent human population south of the Antarctic Circle
Show Answer
Correct Answer: C [ Days and nights can never be longer than 24 hours inside the Circle]
Notes:
Third statement is an incorrect statement because days and nights can be longer than 24 hours inside the Circle. The polar night occurs when the night lasts for more than 24 hours and polar day occurs when day lasts for more than 24 hours.
7. 12 constellations referred to as zodiac belongs to which of the following groupings? (UPSC Prelims 1989)
[A] Imaginary region that encompass the path of the planets
[B] Signs of Roman gods
[C] A group of stars
[D] None of the above
Show Answer
Correct Answer: A [Imaginary region that encompass the path of the planets]
Notes:
Zodiac constellations are the 12 constellations that lie along the plane of the ecliptic, which is defined by the circular path of the Sun across the sky, as seen from Earth.
