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:
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:
Gravel is larger than other partlicles. The clay is the smallest. Sand is larger than silt and clay. So option A is the correct answer.

Notes:
A Quadrant is the instrument used for measuring altitudes and angles in navigation and astronomy. A quadrant is an instrument that is used to measure angles up to 90°.

Notes:
The Pyrenees are a mountain range that forms a natural border between Spain and France. They extend for about 430 kilometers from the Bay of Biscay in the Atlantic Ocean to the Mediterranean Sea, and are about 120 kilometers wide at their widest point. The Pyrenees are known for their rugged, snow-capped peaks, which rise to over 3,000 meters in some places. The range is home to a wide variety of flora and fauna, and is a popular destination for outdoor activities such as hiking, mountain climbing, and skiing. The Pyrenees are also home to several protected natural areas, including the Pyrenees National Park in France and the Ordesa y Monte Perdido National Park in Spain.

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:
A hanging valley is elevated above another valley, with one end open to the valley below. There may be a cliff or steep formation where they meet. When the glaciers melt, the tributary troughs are left as hanging valleys high on the walls of the main glacial valley.

Notes:
Planetary winds are also known as permanent winds. The trade winds, the Easterlies and the Westerlies are known as planetary or permanent winds as they continuously blow throughout the year. These winds always blow in a particular direction. Monsoon is not a planetary wind.

Notes:
The Lighthouse Reef is actually an atoll in the Caribbean Sea. It is a part of the Belize Barrier Reef. The Great Blue Hole is a marine sinkhole, lies near the center of the Lighthouse Reef.

Notes:
Mertz Glacier is located in the continent of Antarctica. It is about 45 miles long, heavily crevassed glacier in George V Coast of East Antarctica. The extension of this glacier into the Southern Ocean is called the Mertz Glacial Tongue.
