World & Physical Geography MCQs

Notes:
The Katanga Plateau in the Democratic Republic of the Congo is known for its rich deposits of copper and uranium. The plateau is located at an altitude of 1220m (4,000 ft) above sea level, which makes it cooler than the surrounding area. The mean annual temperature is 19-20 °C. The plateau is also known for its copper production. Other minerals that are mined in the Katanga Plateau include: Cobalt, Zinc, Silver, Gold, Tin. The Katanga Plateau is also good for farming and ranching. The seasonal rainfall makes it a fertile arable area.

Notes:
Mercury, Venus, Earth and Mars are called as the inner planets as they lie between the sun and the belt of asteroids. Inner planets are also known as Terrestrial planets meaning earth-like as they are made up of rock and metals, and have relatively high densities.

Notes:
The temperate grasslands of North America are known as the Prairies (Fig. 9.1). It is a region of flat, gently sloping or hilly land. For the most part, prairies are treeless but, near the low lying plains, flanking river valleys, woodlands can be found. Tall grass, upto two metres high, dominates, the landscape. It is actually a “sea of grass

Notes:
The Red Sea is a seawater inlet of the Indian Ocean, lying between Africa and Asia. The connection to the ocean is in the south through the Bab el Mandeb strait and the Gulf of Aden.

Notes:
Tropical cyclones originate in the doldrums near the equator, about 10° away from it.

Notes:
An Isochrone is defined as “a line drawn on a map connecting points at which something occurs or arrives at the same time".

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:
Mars is a planet with a very similar daily cycle as the Earth. Its sidereal day is 24 hours, 37 minutes and 22 seconds and its solar day 24 hours, 39 minutes and 35 seconds. A Martian day (referred to as “sol”) is therefore approximately 40 minutes longer than a day on Earth.
Its axial tilt is most similar to Earth. Mars’ tilt is 25 degrees, just a fraction away from the Earth’s 23.5 degrees. Mars also has a very elliptical orbit. Because of this, the difference between its closest and most distant point along its orbit vary by 19%.

Notes:
The Zambezi River is the largest river from Africa that flows into the Indian Ocean. It is also the fourth longest river in Africa and the longest east flowing river there. Victoria Falls is a waterfall on the Zambezi River.

Notes:
Uranus is four times the size of the Earth. It appears greenish in color because of the large amount of methane gas present in its atmosphere.
