World & Physical Geography MCQs

Notes:
The Syrian desert also known as the Jordanian Steppe or the Badia, is a region of desert, semi-desert and steppe covering 500,000 square kilometers. It covers the countries: Iraq, Jordan and Syria.

Notes:
The Gobi Desert is a large desert is East Asia. It covers parts of Northern and Northeastern China and of Southern Mongolia. It has an area of 1,295,000 square kilometres. It is a cold Desert.

Notes:
The Taklamakan is a desert in Southwest Xinjiang in Northwest China. It has an area of 337,000 square kilometres. It is the world’s second largest shifting sand desert with about 85% made up of shifting sand dunes.

Notes:
The Atacama desert in Chile, South America is the driest desert in the world. It owes its extreme aridity to a constant temperature inversion due to the cool north-flowing Humboldt ocean current and to the presence of the strong Pacific anticyclone.

Notes:
The closest point to the Sun in a planet’s orbit is called perihelion.
The position of the Earth when it is at the greatest distance from the sun is called the Aphelion.

Notes:
Gulf of Nicoya is a gulf facing the Pacific Ocean which separates the Nicoya Peninsula from the mainland of Costa Rica. It houses islands such as Chira Island and Island San Lucas. Nicoya is one of the five “Blue Zones” of the world. This gulf lies adjacent to several nature reserves and wildlife parks.

Notes:
Humidity is the amount of water vapour present in air. 
Absolute Humidity is the weight of actual amount of water vapour present in unit volume of air.
Relative Humidity is the Ratio of water vapour in air at a particular temp. to total amount of water vapour required to saturate the same air at same temperature. It is expressed in %
Specific Humidity is the Weight of water vapour present in per unit weight of air. It is not affected by change in pressure or temperature.

Notes:
Stratus clouds are horizontal.
They are stratified or layered clouds cover big portions of the sky.
These clouds are usually formed due to the mixing of air masses with various temperatures or due to loss of heat.
The presence of stratus clouds means chilly, overcast day.

Nimbus clouds are usually black or dark grey.

Notes:
Nephology is the science of clouds, which is undertaken in the cloud physics branch of meteorology. It is concerned with the study of cloud types, their formation, development and dissipation.

Notes:
Maritime Tropical Air Masses are air masses which are warm, humid and unstable. The source regions of these air masses include the oceans in tropics and sub-tropics such as Mexican Gulf, the Pacific and the Atlantic oceans.
