World & Physical Geography MCQs

Notes:
Geomorphology is the scientific study of landforms, their processes, form and sediments at the surface of the Earth. Geomorphology helps to reconstruct history of the surface of the earth through a study of its forms, the materials of which it is made up of and the processes that shape it.

Notes:
The Big bang theory talks about the expanding universe. The model describes how the universe expanded from an initial state of extremely high density and high temperature. It offers explanation for a broad range of observed phenomena, like the abundance of light elements, the cosmic microwave background (CMB) radiation etc.

Notes:
Galileo Galilei was the first to observe the rings of Saturn in 1610 using his telescope. He called them Saturn’s ears.

Notes:
The hottest temperature ever recorded on Earth was in El Azizia, Libya on September 13, 1922. The temperature reached a staggering 57.8 degrees Celsius (136 degrees Fahrenheit). This record temperature was later contested by a new world record temperature of 56.7°C (134°F) which was recorded in Furnace Creek Ranch, Death Valley, USA. However, the Death Valley record has faced controversies and hence remains debatable.

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

Notes:
The benthic zone is the ecological region at the lowest level of a body of water such as an ocean or a lake, including the sediment surface and some sub- surface layers. Organisms living in this zone are called benthos. They generally live in close relationship with the substrate bottom; many suchorganisms are permanently attached to the bottom.

Notes:
The Sargasso Sea is the only sea in the world with no coastline. It is a region in the gyre in the middle of the North Atlantic Ocean. It is well known for brown Sargassum seaweed and calm blue water.

Notes:
Chinook is basically warm winds originally meant a warming wind from the ocean into the interior regions of the Pacific Northwest of the USA. Foehn is a type of dry, warm, down-slope wind that occurs in the lee (downwind side) of a mountain range. Harmattan is a dry and dusty north-easterly trade wind which blows from the Sahara Desert over the West African. Mistral is a strong, cold, north-westerly wind that blows from southern France into the Gulf of Lion in the northern Mediterranean. Sirocco is a Mediterranean wind that comes from the Sahara and can reach hurricane speeds in North Africa and Southern Europe.

Notes:
Alluviul soil is loose, unconsolidated sediment that has been eroded, reshaped by water in some form, and redeposited in a non-marine setting. Alluviul soil is typically made up of a variety of materials, including fine particles of silt and clay and larger particles of sand and gravel.

Notes:
Equatorial Low Pressure Belt or ‘Doldrums’ Lies between 10°N and 10°S latitudes. Width may vary between 5°N and 5°S and 20°N and 20°S. This belt happens to be the zone of convergence of trade winds from two hemispheres from sub-tropical high pressure belts.
