World & Physical Geography MCQs

Notes:
Indian ocean lies in the Sunda Trench. The Sunda Trench ,also known as the Java Trench, is an oceanic trench located in the Indian Ocean near Sumatra. It is formed where the Australian-Capricorn plates subduct under the Eurasian Plate. It is 3,200 kilometres long with a maximum depth of 23,920 feet.

Notes:
Halley’s Comet is one of the most famous comet. It is a “periodic” comet. It returns to Earth’s vicinity about every 75 years and this makes it possible for a human to see it twice in his or her lifetime. The last time it was here was in 1986, and it is projected to return in 2061.

Notes:
Mount Qomolangma is the Tibetan and Chinese name for Mount Everest.

Notes:
Local winds are winds that blow in a limited area and are influenced by local geography. They can blow between small low and high pressure systems. Some examples of local winds include:

• Sea breezes: These winds alternate with land breezes during periods of strong daytime warming or nighttime coolness.
• Loo: These hot and dry winds blow during summers in the northern plains of India.
• Chinook winds: These warm and dry winds move towards the eastern slopes of rocky mountains.

Other types of local winds include:

• Anabatic and katabatic winds
• Foehn winds

Local winds can be dominated by wind patterns when broad-scale winds are weak.

Notes:
Makran is a region in southwestern Pakistan and southeastern Iran. It is located along the coast of the Arabian Sea and stretches from the Iranian province of Sistan and Baluchestan to the Pakistani province of Balochistan. It is a mountainous region with a dry climate, and it is known for its diverse population, including Baloch, Persian, and Arab communities.

Notes:
Please note that the first statement is not correct. Equator has theoretical constant 12 hours of day and night throughout the year, though in practice there are variations of a few minutes due to the effects of atmospheric refraction and because sunrise and sunset are measured from the time that the edge of the Sun’s disk is on the horizon, rather than the center of the disk.

Notes:
The International Date Line is an imaginary line of demarcation on the surface of Earth that runs from the North Pole to the South Pole and demarcates the change of one calendar day to the next.  It passes through the middle of the Pacific Ocean, roughly following the 180° line of longitude but deviating to pass around some territories and island groups. The date becomes one day later as one travels across it in western direction, and one day earlier as one travels across it in eastern direction.

Notes:
Seismic waves that vibrate perpendicular to the direction of their path depend upon a resistance to transverse or “shear” force which does not exist in a liquid or gas medium, so they can only travel in the solid parts of the Earth. P waves in air are simply sound waves and the speed of sound is around 340 m/s for ordinary temperatures.

Notes:
Benguela Current, oceanic current that is a branch of the West Wind Drift of the Southern Hemisphere. It flows northward in the South Atlantic Ocean along the west coast of southern Africa nearly to the Equator before merging with the westward-flowing Atlantic South Equatorial Current.
Guinea Current, surface oceanic current of the Atlantic Ocean, the eastward continuation of the Atlantic Equatorial Countercurrent, off the western coast of Africa near the Gulf of Guinea. The warm, highly saline Guinea Current reaches a depth of less than 660 feet (200 m).

Notes:
At ‘M4’ position of the diagram the height of the tide is at maximum, because in this position earth, moon and sun lies in a straight line.
