World & Physical Geography MCQs

Notes:
Geo-centric theory of solar system was proposed by Ptolemy 2000 years ago. This theory states that all celestial objects, stars, the sun and the planets, all revolved around the earth.

Notes:
Following the sun, Alpha Centauri is the closest star to Earth, located approximately 4.367 light years away. It’s a star system consisting of three stars: Alpha Centauri A, Alpha Centauri B, and Proxima Centauri.

Notes:
Aluminum is the most abundant metal in the Earth’s crust, making up about 8.1% of the crust. However, it’s rarely found in its pure form in nature. Instead, it’s usually found combined with other elements in minerals like bauxite and cryolite. Two common aluminum compounds are alum and aluminum oxide.  The most abundant non-metal in the Earth’s crust is oxygen, which makes up about 46% of the crust.

Notes:
The name “Ecuador” originates from the Latin word “aequator,” which means “equal”. It refers to the country’s geographical position straddling the equator, which bisects the nation into two nearly equal halves. This uniqueness has been reflected in its name to denote its location. In addition to this, Ecuador is the only country in the world to be named after a geographical feature.

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:
Basalt is known as world’s most abundant fine-grained extrusive rock.

Notes:
Moving to equator results in less disturbance for wildlife in that area. Much of the biodiversity around the equator is in the rainforest. As stated before, geographic isolation drove speciation around the equator, increasing the overall uniqueness and amount of species.

Notes:
Kure Atoll is the northern-most coral atoll in the world and is the most remote of the Northwestern Hawaiian Islands, in the Pacific Ocean. Major Island of this atoll is called Green Island.

Notes:
Engilchek Glacier is the largest and the fastest moving glacier in Kyrgyzstan. It is located in the Central Tian Shan Mountains of Issyk-Kul region of northeastern Kyrgyzstan. Also, it is the sixth longest non polar glacier in the world.

Notes:
Fred Hoyle, proposed the Steady State theory.  According to him, the universe is roughly the same at any point of time.
