World & Physical Geography MCQs

Notes:
Dike is a sheet of rock that is formed in a fracture of a pre existing rock body. They can be magmatic or sedimentary in origin.
Kipuka is an area of land surrounded by one or more younger lava flows. They appear to be like islands within a sea of lava flows.
Guyot is an isolated flat-topped underwater volcano mountain. They are also known as tablemount. They were first recognised by Harry Hess in 1945.

Notes:
Nubbin A small and gentle hill consisting of a bedrock core dotted with rounded residual blocks is called a Nubbin. They occur in patterned groups. They are most common in granitic rocks.
Panhole is a shallow depression or basin eroded into flat or gently sloping cohesive rock. Panholes are also called as armchair hollows, weathering pans, etc. They are well developed in granitic rocks and sandstone. They are commonly found in desert environments.

Notes:
The “Coast Tram” of Belgium is a public transport service connecting the cities and towns of the entire Belgian coast starting from the town near the French border to another town near the Dutch border. It is 67 kilometres long tramway. It started its operation in 1885.

Loess Plateau is a plateau located in China. It is 1250-2000 metres above sea level. It is bounded by the Yellow River’s Ordos Loop and its tributaries such as Wei and Fen Rivers. It was one of the earliest locations of Chinese Civilization. Erosion of silt from Loess Plateau and Yellow River floods lead to the great fertility of the North China Plain.

Notes:
The Andes Mountains in South America, are the longest mountain chain in the world. Mt. Aconcagua is the highest peak in the Andes.

Notes:
The proportion of insolation that is reflected back by the surface is called its albedo. It depends upon the nature of the surface upon which the solar radiation is incident and the angle of incidence of the solar beam. The albedo for the earth as a whole is called the planetary albedo and it is 35%.

Notes:
Diosso Gorge is located in the Republic of Congo. Diossa was the capital of the Loango Kingdom. Continuous erosion in this area has created the “Grand Canyon of Congo” known as Diosso Gorge. This gorge is absolutely stunning with the views of the rainforest, rock ridges, red rock cliffs etc.

Notes:
The Rwenzori Mountains are located on the border between the Democratic Republic of Congo and Uganda. It is located within eastern Equatorial Africa. The highest peak of Rwenzori Mountains is Mount Stanley which is 5109 metres above sea level. These mountains houses Virunga National Park of the Democratic Republic of Congo and Rwenzori Mountains National Park of Uganda. European exploration of Africa termed Ruwenzori Mountains as the Mountains of Moon because of its permanently ice-capped and glaciated upper regions and its mountains streams which form a source to the Nile River.

Notes:
Air mass is a large body of air whose physical properties especially temperature and moisture content are relatively uniform horizontally. The temperature, pressure and humidity are uniform and the whole area of air or the mass of air behaves like a single unit.
