World & Physical Geography MCQs

Notes:
Senegal does share a land border with Guinea-Bissau. Guinea-Bissau, officially the Republic of Guinea-Bissau, is a country in West Africa. It borders Senegal to the north and Guinea to the south-east.

Notes:
Venezuela, Brazil, Guyana, and Suriname share the location of the geographical formation “Tepui” table-top mountains. A tepui is a table-top mountain or mesa found in the Guiana Highlands of South America, especially in Venezuela and western Guyana. Tepuis tend to be found as isolated entities rather than in connected ranges, which makes them the host of a unique array of endemic plant and animal species.

Notes:
“Thjorsa River” is Iceland’s longest river at 230 kilometres. It is in the south of the island. It is a glacier river and has its source on the glacier Hofsjokull. It flows out through narrow gorges in the highlands of Iceland.

Notes:

Notes:
The Islamic Republic of Mauritania is a desert country located in northwest Africa. Almost 2/3 of the country is covered by the Western Sahara Desert.

Notes:
The correct chronological order of the geological eras (in million years before the present) are as follows:- Cretaceous: 72.1-145; Jurassic: 152.1-201.3; Triassic: 208.5-201.3; Permian: 254.2-298.9.

Notes:
Gneiss is a high grade metamorphic rock formed by the metamorphosis of granite which is a sedimentary rock. Gneiss is typically associated with major mountain building episodes. It is often foliated (composed of layers of sheet-like planar structures), characterized by alternating darker and lighter colored bands, called “gneissic banding”.

Notes:
Plates are pieces of Earth’s crust and uppermost mantle, together referred to as the lithosphere. The plates are around 100 km thick and consist of two principal types of material: oceanic crust (also called sima from silicon and magnesium) and continental crust (sial from silicon and aluminium).

Notes:
The continental shelf is the extended perimeter of each continent and associated coastal plain. Much of the shelf was exposed during glacial periods, but is now submerged under relatively shallow seas (known as shelf seas) and gulfs, and was almost similarly submerged during other interglacial periods. The continental margin, between the continental shelf and the abyssal plain, comprises a steep continental slope followed by the flatter continental rise. Sediment from the continent above cascades down the slope and accumulates as a pile of sediment at the base of the slope, called the continental rise. Though the continental shelf is treated as a physiographic province of the ocean, it is not part of the deep ocean basin proper, but the flooded margins of the continent.

Notes:
Cotopaxi is an active stratovolcano in the Andes Mountains, located in the Latacunga canton of Cotopaxi Province, south of Quitoand northeast of the city of Latacunga, Ecuador, in South America.It is the second highest summit in Ecuador, reaching a height of 5,897 m. It is one of the world’s highest volcanoes.
