World & Physical Geography MCQs

Notes:
Iceland houses the “Lake Myvatn”. Lake Myvatn is a shallow lake situated in an area of active volcanism in the north of Iceland, not far from the Krafla volcano. It has a high amount of biological activity. The lake and the surrounding wetlands provide a habitat for a number of waterbirds, especially ducks. The lake was created by a large basaltic lava eruption 2300 years ago.

Notes:
Indonesia’s highest mountain is “Puncak Jaya”. Puncak Jaya, also known as  Carstensz Pyramid or Mount Jayawijaya or Mount Carstensz, is the highest mountain in Indonesia, on the island of New Guinea, with an elevation of 4,884 m. It is the highest peak of an island on Earth, and the highest peak in Oceania. Located in the Sudirman Range of the western central highlands of Papua Province, Indonesia.

Notes:
Mercury is the innermost planet (nearest to the Sun) in the Solar System. It is also the smallest, and its orbit is the most eccentric (that is, the least perfectly circular) of the eight planets. It orbits the Sun once in about 88 Earth days, completing three rotations about its axis for every two orbits.

Notes:
A flash flood is a rapid flooding of geomorphic lowlying areas: washes, rivers, dry lakes and basins. It may be caused by heavy rain associated with a severe thunderstorm, hurricane, tropical storm or cyclone, or melt-water from ice or snow flowing over ice sheets or snowfields.

Notes:
Taiga is the world’s largest land biome. It makes up 29% of the world’s forest cover. Also known as boreal forest or snow forest, it is characterized by coniferous forests consisting mostly of pines, spruces and larches. The largest areas of Taiga are located in Russia and Canada.

Notes:
A levee, dike, dyke or flood bank is a broad, low embankment built up along the banks of a river channel during floods. Levees are usually parallel to the way the river flows, so levees can help direct the flow of the river. Levees can also be artificially created or reinforced.

Notes:
The Sahara is the largest subtropical hot desert and third largest desert after Antarctica and the Arctic. At over 9,400,000 square kilometres, it covers most of North Africa, making it almost as large as China or the United States. In terms of area, the Arabian and the Kalahari Deserts come at second and third places among subtropical deserts.

Notes:
Australia is the world’s largest producer of bauxite, with production amounting to an estimated 110 million metric tons in 2021.

Notes:
Permafrost is ground that remains at or below 0°C for at least two consecutive years, covering 15% of Earth’s land area (over 23 million sq.km). It is primarily found in the Northern Hemisphere, particularly in Russia, Canada, and Greenland, and also occurs in mountainous regions of the Southern Hemisphere. Permafrost can form on land and beneath oceans, sometimes extending deep below the surface. It can create landforms such as ‘palsas’ (peat mounds with frozen cores) and ‘pingos’ (ice-cored hills).

Notes:
Poland is home to numerous stunning lakes, with Lake Hańcza standing out as the deepest, reaching depths that make it unique in the country.
