World & Physical Geography MCQs

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:
Shimla is the place among the options where water boils at low temperature. At higher altitudes, air pressure is lower. When atmospheric pressure is lower, such as at a higher altitude, it takes less energy to bring water to the boiling point. Less energy means less heat, which means water will boil at a lower temperature at a higher altitude.

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:
Kra Isthmus connects the Malay Peninsula with the mainland of Asia and is known as Devil`s neck.

Notes:
• Aleutian Islands are chain of small islands that separate the Bering Sea (north) from the main portion of the Pacific Ocean (south). They extend in an arc southwest, then northwest, for about 1,100 miles (1,800 km) from the tip of the Alaska Peninsula to Attu Island, Alaska, U.S.
• Kermadec Islands are volcanic island group in the South Pacific Ocean, 600 mi (1,000 km) northeast of Auckland, New Zealand; they are a dependency of New Zealand.
• Sunda Islands are mainly in Indonesia, between the South China Sea and the Indian Ocean, comprising the western part of the Malay Archipelago.
• South Georgia and the South Sandwich Islands are a collection of islands in the South Atlantic Ocean.

Notes:
Hainan Island is the southernmost point in the province of China and it is also the smallest province of the People’s Republic of China. This province comprises various islands in the South China Sea.

Notes:
Gulf of Mexico is the largest Gulf in the world. It is an ocean basin and a marginal sea of the Atlantic Ocean. It covers an area of 600,000 square miles. It is also the deepest gulf in the world.

Notes:
The Tidal Hypothesis was proposed by James Jeans and Harold Jeffreys. This theory explains the origin of the earth and the solar system.

Notes:
The Mesozoic Era began 251 million years ago. Surviving reptiles and amphibians evolved into many other species (like dinosaurs), hence the “Age of Reptiles”.

Notes:
The boundary between the inner core and the outer core is called as the Lehmann Discontinuity. It is also called as the Lehmann-Bullen discontinuity.
