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. Which of the following layer of the earth is termed as Sial?
[A] Core
[B] Crust
[C] Mantale
[D] None of the above
Show Answer
Correct Answer: B [Crust]
Notes:
Outermost layer of the earth- crust is also known as Sial because major constituent elements of crust are silica (Si) and Aluminium (Al). Mantle is also known as Sima because major constituent elements of mantle are magnesium and silicon. Innermost layer of the earth- core is also known as Nife because core is mainly composed of the iron (fe) and nickel (Ni).
3. When we go deep into the earth:
[A] Temperature decreases
[B] Temperature increases
[C] Temperature remains constant
[D] None of the above
Show Answer
Correct Answer: B [Temperature increases]
Notes:
During Volcano Molten lava erupted from the earth’s interior, support that temperature increases towards the centre of the earth. The temperature at the centre is estimated to lie somewhere between 3000°C and 50000C.
4. Which among the following is correct about Sirocco?
[A] It’s a warm & dry wind
[B] It’s a warm & moist wind
[C] It’s a cold & moist wind
[D] It’s a winter wind that blows in pacific ocean
Show Answer
Correct Answer: A [It’s a warm & dry wind]
Notes:
Sirocco is a warm, dry and dusty laden local wind which blows in northerly direction from Sahara desert over North Africa as a dry wind and picks up moisture as it crosses the Mediterranean.
Since they carry red dust over Sahara, the rainfall which they cause is called blood rain sometimes.
5. Continent where Tundra type of climate is NOT found?
[A] Asia
[B] North America
[C] Europe
[D] Australia
Show Answer
Correct Answer: D [Australia]
Notes:
In the continent of Australia, the northern section of Australia has a more tropical influenced climate, hot and humid in the summer, and quite warm and dry in the winter, while the southern parts are cooler with mild summers and cool, sometimes rainy winters. So it doesn’t have Tundra type of climate.
6. In which of the following River Jordan drains?
[A] Atlantic Ocean
[B] Dead sea
[C] Red sea
[D] Gulf of suez
Show Answer
Correct Answer: B [Dead sea]
Notes:
River Jordan drains into the Dead Sea. The Jordan River flows through the Middle East and forms part of the border between Israel and Jordan. It ultimately empties into the Dead Sea, which is a landlocked saltwater lake known for its high salinity and unique geological features.
7. Which among the following is the correct definition of ” Annual Precipitation” of a particular place / area?
[A] All forms of precipitation converted to the quantity of liquid water
[B] All forms of precipitation converted to the quantity of ice
[C] Total Actual amount of Rains, Snow, hail, sleet etc.
[D] None of the above
Show Answer
Correct Answer: A [All forms of precipitation converted to the quantity of liquid water]
Notes:
The correct definition of “Annual Precipitation” refers to the total amount of all forms of precipitation (rain, snow, sleet, hail) converted to the equivalent quantity of liquid water over a year. This measurement is crucial for understanding climate patterns and water resource management. For instance, the average annual precipitation in the Amazon rainforest can exceed 2000 mm, importantly influencing its biodiversity.
8. The aeration zone in earth’s lithosphere lies at ___?
[A] Above earth surface
[B] Below earth surface & above Water Table
[C] Below Earth’s surface and parallel to water table
[D] Below earth’s surface and below water table
Show Answer
Correct Answer: B [Below earth surface & above Water Table]
Notes:
The aeration zone, also known as the unsaturated zone, is located below the Earth’s surface and above the water table. In this zone, soil pores contain both air and water, allowing for processes like root respiration and gas exchange. This zone is crucial for groundwater recharge, as it filters water before it reaches the saturated zone. The water table marks the boundary between the aeration zone and the saturated zone, where all soil pores are filled with water.
9. Which among the following is the most saline open sea of the world?
[A] Kara Sea
[B] Persian Gulf
[C] Red Sea
[D] Yellow Sea
Show Answer
Correct Answer: C [ Red Sea]
Notes:
The salinity of Red Sea is greater than the world average, approximately 4 percent. It has been also cited as most saline open sea due to high rate of evaporation and very little precipitation, Lack of significant rivers or streams draining into the sea and limited connection with the Indian Ocean, which has lower water salinity.
10. Identify the wind based on the following information:
- It is a cold, dry, and dust-laden wind.
- This wind blows from the Sahara Desert over the West African subcontinent into the Gulf of Guinea.
- Locally, it is referred to as “the Doctor.”
