World & Physical Geography MCQs

Notes:
The Great Dividing range in Australia, is the source for the rivers Darling and Murray. Mt. Kosciuszko is the highest peak in this range. The Sierra Nevada mountain ranges is in California, US. Mt.Whitney is the highest peak in Sierra Nevada. It is an important habitat for many Red Indians.

Notes:
The Bhuikhel plain is a large plain located in the western part of Kathmandu, Nepal at the foot of Swayambhu hill. It is famous for the Buddhist Samyak festival held here. 

The Utkal plain is a coastal plain in the state of Odisha, India. It includes the delta of the Mahanadi River, Brahmani River, Baitarani River. The Chilkha lake is the most prominent physiographic feature of this plain.

The Laramie Plains are situated at an elevation of 2400 m in south central Wyoming in the United States. The plains have historically been used for livestock raising, primarily of sheep and cattle.

Notes:
Albertine Rift or Albertine Rift Mountains are located on the eastern side of the African continent. It forms the western branch of the East African Rift. It covers countries such as Uganda, Democratic Republic of Congo, Rwanda, Burundi and Tanzania. It houses geographical features such as Lake Albert, the Rwenzori Mountains, Lake Edward, Virunga Mountains, Lake Kivu and Lake Tanganyika. These mountains formed when the Somali plate split from the rest of the African continent due to tectonic movements.

Notes:
Dew is formed when moisture is deposited in form of water droplets on cooler surfaces of solid objects such as stone, glass, blades, plant leaves. It forms when temperature of air falls below dew point but above freezing point.

Notes:
The Arctic Ocean is the smallest and shallowest of the world’s five major oceans. It is also known as the coldest of all the oceans.
It is sometimes classified as an estuary of the Atlantic Ocean.

Notes:
The Siberian Shelf in the Arctic Ocean – stretches to 1,500 kilometers (930 mi) in width. Continental shelves are usually covered with a layer of sand, silts, and silty muds.

Notes:
Abyssal plains are the extremely flat and featureless plains of the deep ocean floor. They are considered as the levelest areas on the earth. They cover a major portion of the ocean floors between the depths of 3000m to 6000m.

Notes:
Cuba is located in the northern Caribbean Sea at the confluence with the Gulf of Mexico and the Atlantic Ocean. Cuba shares maritime borders with the USA to the north and north-west; the Bahamas to the north; Mexico to the west; Haiti to the east; Jamaica and the Cayman Islands to the south.

Notes:
The differential heating of the Sun at the equator and the poles causes a difference in the temperature of ocean water.
Hence, the difference in heating and surface temperatures play a key role in movements of ocean water.
Under the action of Coriolis force, the movement of ocean currents in the northern hemisphere is in the clockwise and in the southern hemisphere it is in the anti-clockwise direction. Hence it can be said that ocean currents obey Ferrel’s law.

Notes:
B – Horizon also known as the subsoil, this layer lies below the A-horizon and the E-horizon. It contains minerals which reflect the physical and chemical alteration of the parent rock. It is a zone of illuviation i.e., the nutrients that are leached out of the A-horizon and E-horizon get accumulated here.
