World Geography General Knowledge Questions


In which of the following regions, maize is used as staple food ?
[A]Western Europe
[C]Middle Africa
[D]South-East Asia

Middle Africa
Maize or corn is a cereal crop that is grown widely throughout the world in a range of agroecological environments. The grains are rich in vitamins A, C and E, carbohydrates, and essential minerals, and contain 9% protein. They are also rich in dietary fiber and calories which are a good source of energy. (Staple food is the name for a food that can be stored easily, and eaten throughout the year.) It’s an important staple food for more than 1.2 billion people in Middle Africa.


Carajás Mine is located in which of the following countries?

The Carajás Mine is the largest iron ore mine in the world. It is located in the state of Pará in the Carajás Mountains of Northern Brazil.


Four Corners Monument is located in which of the following countries?
[A]United States

United States
Four Corners Monument is the quadripoint meeting four states of US viz. Arizona, Colorado, New Mexico and Utah. It is located in South-western United States and is the only point shared by four states in America. It is also a boundary between two semi-autonomous Native American governments viz. The Navajo Nation and Ute Mountain.


Which of the following is not a feature of El Niño Southern Oscillation (ENSO)?
[A]Periodic disruption of normal sea surface temperature in Pacific Ocean
[B]Reversal of Westerlies
[C]Rise of sea level along equator
[D]Decrease in productivity along the west coast of South America

Reversal of Westerlies
ENSO results in reversal of trade winds not westerlies. A periodic disruption of normal sea surface and atmospheric circulation patterns in the Pacific Ocean is called El Niño Southern Oscillation (ENSO). The warm phase of ENSO (El Niño) is associated with the eastward movement of the Pacific warm pool, halting or reversal of the trade winds, a rise in sea level along the equator, a decrease in productivity along the west coast of South America, and, in very strong El Niños, worldwide changes in weather. El Niños fluctuate with the cool phase of ENSO (La Niña conditions), which are associated with cooler than normal water in the eastern tropical Pacific.


Majid Gyre is a feature of which of the following Oceans?
[A]Pacific Ocean
[B]Indian Ocean
[C]Atlantic Ocean
[D]Arctic Ocean

Indian Ocean
The Indian Ocean consists of one gyre, the Indian Ocean (Majid) Gyre, which exists mostly in the Southern Hemisphere. It is named after Ahmad Bin Majid, the 15th-century Arab mariner. Following table shows the Oceans and their respective Gyres

The Coriolis force is maximum at __?
[D]Mountain peaks

The Coriolis effect influences the paths of moving objects on Earth and is caused by Earth s rotation. Because Earth s surface rotates at different velocities at different latitudes, objects in motion tend to veer to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. The Coriolis effect is nonexistent at the equator but increases with latitude, reaching a maximum at the poles.


Bathymetry is related to which of the following studies?
[A] Climatology
[B] Oceanography
[C] Economic Geography
[D] Astronomy

Bathymetry is the measurement of ocean depths and the charting of ocean floor topography. The varied bathymetry of the ocean floor was first determined using soundings to measure water depth. Later, the development of the echo sounder gave ocean scientists a more detailed representation of the sea floor. Today, much of our knowledge of the ocean floor has been obtained using various multibeam echo sounders or side-scan sonar instruments (to make detailed bathymetric maps of a small area of the ocean floor); satellite measurement of the ocean surface (to produce maps of the world ocean floor); and seismic reflection profiles (to examine Earth structure beneath the sea floor).


Who among the following gave the theory of continental drift?
[A]Arthur Holmes
[B]Alfred Wegener
[C]Jean-Baptiste Élie de Beaumont
[D]Harry Hess

Alfred Wegener
According to the theory of plate tectonics, the outermost portion of Earth is composed of a patchwork of thin, rigid lithospheric plates that move horizontally with respect to one another. The idea began as a hypothesis called continental drift proposed by Alfred Wegener at the start of the 20th century. He suggested that about 200 million years ago, all the continents were combined into one large continent (Pangaea) surrounded by a single large ocean (Panthalassa). Harry Hess advanced the idea of sea floor spreading.


Which of the following were the main gases in the initial atmosphere of Protoearth?
[A]Hydrogen and Helium
[B]Nitrogen and Carbon Dioxide
[C]Hydrogen and Nitrogen
[D]Oxygen and Carbon dioxide

Hydrogen and Helium
Protoearth, more massive and larger than Earth today, was molten and homogenous. The initial atmosphere, composed mostly of hydrogen and helium, was later driven off into space by intense solar radiation.


Hoover Dam is built on which of the following rivers?
[A]Colorado River
[B]Nile River
[C]Rhine River
[D]Niger River

Colorado River
Hoover dam is a concrete and gravity dam in black canyon of the Colorado river on the Border between the US states of Arizona and Nevada.
