World & Physical Geography MCQs

Notes:
Jupiter’s moon Ganymede is the largest satellite in the solar system. It is Larger than Mercury and Pluto. Jupiter is the largest planet in the solar system.

Notes:
Eskimos live in the tundra climate. The tundra is part of the polar region, which is characterized by a frigid climate. The polar region includes the Arctic and the Antarctic. Eskimos are indigenous people who have traditionally lived in the northern circumpolar region. This region includes eastern Siberia, Alaska, Canada, and Greenland. Eskimos live in igloos during the winter and portable huts in the summer. The word “igloo” is the Eskimo word for “house”. Eskimos have developed unique skills and adaptations to survive in the extreme cold climates.

Notes:
Goldilock region is the space which is neither too hot nor too cold and has conditions which are a must for life. So the Goldilock zone is a habitable zone.

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:
Cold ocean currents contribute to the formation of coastal deserts. Cold ocean currents contribute to the formation of coastal deserts. Air blowing toward shore, chilled by contact with cold water, produces a layer of fog. This heavy fog drifts onto land. Although humidity is high, the atmospheric changes that normally cause rainfall are not present. A coastal desert may be almost totally rainless, yet damp with fog.
The Atacama Desert, on the Pacific shores of Chile, is a coastal desert. Some areas of the Atacama are often covered by fog. But the region can go decades without rainfall. In fact, the Atacama Desert is the driest place on Earth. Some weather stations in the Atacama have never recorded a drop of rain. (National Geographic)

Notes:
Seabed is a vast repository of minerals, including the precious cobalt, zinc, manganese and rare earth materials that are needed for smart phones, laptops and hybrid cars. They are present in the three forms:

• Polymetallic manganese nodules that remain strewn across the ocean floor
• Cobalt-rich ferromanganese crusts that cover the seamounts
• Massive polymetallic sulphide deposits around hydrothermal vents.

Notes:
Polar Vortex is a whirling cold winds present at both North Pole and South Pole.
It results because of the increased temperature difference between the dark, frigid Arctic and the warm tropics. There are two vortices, one in the layer of the upper atmosphere known as the stratosphere and one in the lower section, where our weather happens, called the troposphere. These two features interact with each other and can affect the meteorological goings-on outside of the Arctic.

Notes:
In Northern Atlantic, there is a very low decrease of temperature with increasing latitudes towards north. This is because of the Gulf Stream currents which are warm currents. However, in southern Atlantic, the decrease of temperature with increasing latitude is more pronounced.

Notes:
A black hole is a place in space where gravity pulls so much that even light cannot get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying. Black holes can be big or small.

Notes:
The equator is a line which is not real drawn around a sphere or planet, such as the Earth. It is one of the lines known as a line of latitude, or circle of latitude. The name “equator” is Latin for “even-maker”; at equator the day and night are exactly the same length around the year. The equator passes through 13 countries: Ecuador, Colombia, Brazil, Sao Tome & Principe, Gabon, Republic of the Congo, Democratic Republic of the Congo, Uganda, Kenya, Somalia, Maldives, Indonesia and Kiribati.
