World & Physical Geography MCQs

Notes:
Lake Victoria is one of the African Great Lakes. The lake was named after Queen Victoria. It makes the border tripoint of Kenya , Tanzania & Uganda.

Notes:
Lagrange point is position in space where combined gravitational forces of two large bodies, such as Earth and sun or Earth and moon, equal centrifugal force felt by a much smaller third body. The interaction of these forces creates point of equilibrium where spacecraft may be “parked” to make observation. These points are named after Joseph-Louis Lagrange, an 18th-century mathematician. There are 5 such points between earth and sun namely – L1, L2, L3, L4 and L5. In these orbits, the satellite requires very little energy to maintain its orbit and it will not be eclipsed from the sun

Notes:
Jet streams are fast flowing winds i.e air currents. They are narrow and meandering air currents in the atmosphere of Earth. On Earth, the main jet streams are located near the altitude of the tropopause and are westerly winds. Their paths typically have a meandering shape.

Notes:
A leap second is a one-second adjustment that is occasionally applied to Coordinated Universal Time. It is to accommodate the difference between precise time and imprecise observed solar time.

Notes:
Kazakhstan is the world’s largest uranium producer. In 2022, Kazakhstan produced 21,227 metric tons of uranium, which accounted for 43% of the world’s uranium supply. Kazakhstan has been a major uranium producer for over 50 years.  Other top uranium producers include:

• Canada, which produced 7,351 metric tons of uranium in 2022
• Namibia, which produced 11% of the world’s uranium in 2022
• Uzbekistan, which produced about 3,300 metric tons of uranium in 2022

Kazakhstan has 12% of the world’s uranium deposits. The Chu-Sarysu basin in central Kazakhstan accounts for over half of the country’s known uranium resources.

Notes:
A horst is the raised fault block bounded by normal faults. It is a raised block of the Earth’s crust that has lifted, or has remained stationary, while the land on either side has subsided. The Vosges Mountains in France and Black Forest in Germany are examples of horsts, as are the Table,Jura and the Dole mountains.

Notes:
Horst and graben refer to regions that lie between normal faults and are either higher or lower than the area beyond the faults. While a horst represents a block pushed upward relative to the blocks on either side by the faulting, and a graben is a block generally long compared to its width that has been lowered relative to the blocks on either side due to the faulting. 

Notes:
The latitude that pass through Sikkim also pass through Rajasthan. 27 degree centigrade latitude passes through Gangtok of sikkim and Alwar in Rajasthan.

Notes:
Alluvial is loose, unconsolidated soil or sediment that has been eroded, reshaped by water in some form, and redeposited in a non-marine setting. Alluvium is typically made up of a variety of materials, including fine particles of silt and clay and larger particles of sand and gravel. It is indicated by the potion marked with ‘A’.

Notes:
Angria Atoll is a bank and a shallow sunken atoll, off the west coast of India. It is located 65 miles to the West of Vijaydurg, Maharashtra.
