Very Important GK Questions of Geography

9. Which among the following can best define the Neolithic Revolution ?
[A]Green Revolution
[B]Technology Revolution
[C]Milk Revolution
[D]Agricultural Revolution

Explanation:
The Neolithic Revolution or Neolithic Demographic Transition, sometimes called the Agricultural Revolution, was the world’s first historically verifiable revolution in agriculture. It was the wide-scale transition of many human cultures from a lifestyle of hunting and gathering to one of agriculture and settlement which supported an increasingly large population. Archaeological data indicates that various forms of plants and animal domestication evolved in separate locations worldwide, starting around 12,000 years ago.

10. What among the following is a partially enclosed body of water along the coast where freshwater from rivers and streams meets and mixes with salt water from the ocean ?
[A]Estuary
[B]Ria
[C]Tidal bore
[D]Lagoon

Explanation:
An estuary is a partly enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Estuaries form a transition zone between river environments and ocean environments and are subject to both marine influences, such as tides, waves, and the influx of saline water; and riverine influences, such as flows of fresh water and sediment. The inflows of both sea water and fresh water provide high levels of nutrients in both the water column and sediment, making estuaries among the most productive natural habitats in the world.

11. The ratio of the partial pressure of water vapor in an air-water mixture to the saturated vapor pressure of water at a given temperature is termed as:
[A]Relative Humidity
[B]Absolute humidity
[C]Specific Humidity
[D]None of the above

Explanation:
Relative Humidity is the ratio of the partial pressure of water vapor in an air-water mixture to the saturated vapor pressure of water at a given temperature. The relative humidity of air in a closed system will vary with both temperature (which determines the saturated vapor pressure) and total pressure (which implies

changes in the vapor partial pressure).

12. On which among the following dates, Vernal equinox occurs__?
1. March 20-21
2. December 19-20
3. April 21-22
4. September 20-21
Choose the correct option from the codes given below:
[A]1 & 2
[B]2 & 3
[C]3 & 4
[D]1 & 4

Explanation:
An equinox occurs twice a year (around 20 March and 22 September), when the tilt of the Earth’s axis is inclined neither away from nor towards the Sun, the center of the Sun being in the same plane as the Earth’s equator. The term equinox can also be used in a broader sense, meaning the date when such a passage happens. The name “equinox” is derived from the Latin aequus (equal) and nox (night), because around the equinox, night and day are about equal length.

13. Which among the following states is not covered by the Chhota Nagpur Plateau ?
[A]West Bengal
[B]Orissa
[C]Chhattisgarh
[D]Assam

Explanation:
The Chhota Nagpur Plateau (also referred as Chhota Nagpur) is a plateau in Eastern India, which covers much of Jharkhand state as well as adjacent parts of Orissa, West Bengal, Bihar and Chhattisgarh. The total area of the Chhota Plateau is approximately 65000 square kilometers. The highest point of Chhota Nagpur plateau is Pareshnath Hill.

14. Mahanadi river originates in which among the following states of India?
[A]Chhattisgarh
[B]Odisha
[C]Manipur
[D]Assam

Explanation:
The Mahanadi is a major river in East Central India. It drains an area of around 141,600 km² and has a total course of 858 km. The river flows through the states of Chhattisgarh and Odisha. It originates from the highlands of Chhattisgarh through collection of an array of streams and reaches Bay of Bengal. Farthest headwaters of Mahanadi are located in the Pharsiya village in Dhamtari district of Chhattisgarh

15. Which of the following mountain ranges in India is known as a young fold mountain range?
[A]Aravali
[B]Satpura
[C]Vindhyan
[D]Himalayas

Explanation:
The Himalayas are among the youngest mountain ranges on the planet and consist mostly of uplifted sedimentary and metamorphic rock. They stretch from the Indus river in the West to the Brahmaputra river in the East. According to the modern theory of plate tectonics, their formation is a result of a continental collision or progeny along the convergent boundary between the Indo-Australian Plate and the Eurasian Plate. This is referred to as a fold mountain.

16. Soloman Islands are located in__:

[A]North Atlantic Ocean

[B]South Atlantic Ocean

[C]North Pacific Ocean

[D]South Pacific Ocean

Explanation:
The Solomon Islands are a collection of nearly one thousand islands in Oceania that form a sovereign country. They lie to the east of Papua New Guinea in Melanesia. Recently, the islands experienced a powerful 8.0 earthquake followed by a tsunami.
