World & Physical Geography MCQs

Notes:
If the earth stops rotating, then the impact of weight of a body will be minimum on the Poles. The maximum weight will be a t equator. If the earth stops rotating then there would be no centrifugal force whose direction is away from the core. Thus the force due to gravity is not minimised at all and this in turn increases an object’s weight at the equator.

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:
Pebble transport by rivers, sand drift over desert surfaces, soil blowing over fields are examples of saltation. Saltation is a type of particle transport by fluids such as wind or water.

Notes:
The Commonwealth of Nations, is a political association of 53 member states, nearly all former territories of the British Empire. They were ruled by the British empire before getting independence.

Notes:
The Comoros is a volcanic archipelago off Africa’s east coast, in the warm Indian Ocean waters of the Mozambique Channel. It is the only country in the world to be a member of African Union, Francophonie, Organization of the Islamic Conference, Arab League and Indian Ocean Commission.

Notes:
Doldrums or equatorial belt of calms, area around the earth centered slightly north of the equator between the two belts of trade winds. The large amount of solar radiation that arrives at the earth in this area causes intense heating of the land and ocean. This heating results in the rising of warm, moist air; low air pressure; cloudiness; high humidity; light, variable winds; and various forms of severe weather, such as thunderstorms and squalls. Hurricanes originate in this region. The doldrums are also noted for calms, periods when the winds disappear, trapping sailing vessels for days or weeks.

Notes:
First statement is incorrect because the time difference between any two lines of longitude is of four minutes. Second statement is correct.

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:
Damodar is a east flowing river with rift valley due to down warping. Down warp denotes a segment of the earth’s crust that is broadly bent downward.

Notes:
Victoria Falls is a waterfall in southern Africa on the Zambezi River at the border between Zambia and Zimbabwe.
