World & Physical Geography MCQs

Notes:
The sun holds 99.8 % mass of solar system. It is roughly 109 times the diameter of the Earth and about one million Earths could fit inside the sun.

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:
In geography, advection refers to the horizontal movement of a substance or property (such as heat, moisture, or a chemical species) by the movement of a fluid (such as air or water). This movement can occur through the physical process of convection, which involves the transfer of heat or other properties through the movement of fluids.

Advection can be an important factor in weather and climate patterns, as it can influence the distribution of heat, moisture, and other properties within the atmosphere or ocean. For example, advection can play a role in the formation of clouds and precipitation, as well as in the transport of pollutants or other substances within the environment.

Advection can also occur in other systems, such as in the ocean or in the ground. In these cases, the movement of a fluid (such as water or molten rock) can transport substances or properties horizontally through the system.

Notes:
Afganistan is the country included in Ariana. Afganisthan is part of south Asia.

Notes:
Milwaukee Deep is located in the Puerto Rico Trench and is known as the deepest part of the Atlantic Ocean. It was named after the USS Milwaukee, the ship that first discovered it. Deep ocean trenches like the Puerto Rico Trench are formed by the geologic process of subduction, where one tectonic plate is forced under another.

Notes:
The temperate grasslands of South Africa are called the Velds. Pampas are temperate grassland of South America. Llanos are tropical grassland of plains situated to the east of the Andes in Colombia and Venezuela, in north-western South America.

Notes:
The Guinea Current is different because it is located in the Atlantic Ocean off the west coast of Africa, while the other three currents (Canaries, Benguela, and Labrador) are in the Atlantic but are associated with different regions: the Canaries Current flows near the Canary Islands, the Benguela Current flows along the southwest coast of Africa, and the Labrador Current is found off the coast of Canada.

Notes:
Equatorial regions usually experience 2000 mm of rainfall or more in a year. Rainfall is high for most of the year. Many equatorial regions are affected by the ITCZ.

Notes:
Cape Town, as the seat of Parliament, is the legislative capital; Pretoria, as the seat of the President and Cabinet, is the administrative capital; and Bloemfontein, as the seat of the Supreme Court of Appeal, is the judicial capital, while the Constitutional Court of South Africa sits in Johannesburg.

Notes:
The Himalayan Rivers are perennial rivers because they originate in snow covered Himalayan Mountains. They start from the glaciers that seem to melt all over the year. During summers, the snow melts and the rivers get continuous supply of water. On the contrary, the peninsular rivers depend mostly on rainfall for its supply of water and thus become dry during the summer season.
