Atmosphere MCQ Question and Answer | Geography MCQ Question

Sequences of atmospheric layers is correct from below are Troposphere, Tropopause, Stratosphere, Ionosphere.

Exosphere is the farthest layer of atmosphere from Earth's surface, it is located beyond thermosphere. It extends from the hiight of about 600 km to 10000 km.

Anticyclones are caused by winds that blow spirally outwards from the centre. Winds of a high pressure system swirl in the opposite direction as a low pressure system - clockwise north of the equator and counterclockwise south of the equator. This is called anticyclonic flow. Air from higher in the atmosphere sinks down to fill the space left as air blew outward.

The Trade winds are caused by Inflowing movement of air along the earth's surface towards the equator. Trade wind, persistent wind that blows westward and toward the Equator from the subtropical high-pressure belts toward the intertropical convergence zone (ITCZ).

Water Vapour constituents of the atmosphere causes greatest changes in climate and weather. As Earth warms, the rate of evaporation and the ability of air to hold water vapor both rise, increasing the amount of water vapour in the air. Because water vapour is a greenhouse gas, this leads to further warming.

The velocity of winds is related to Pressure gradient in the direction of their flow. Winds in the upper levels will blow clockwise around areas of high pressure and counterclockwise around areas of low pressure. The speed of the wind is determined by the pressure gradient.

Mediterranean climates is found in coastal areas of California North America, Central Chile in South America and South-West tip of West Australia. Winter precipitation is primarily the result of cold fronts that move across the Pacific Northwest and northern California. The frequency of these storms decreases from north to south.

The ideal conditions for the phenomenon of temperature inversion to occur are Long nights, Calm and stable air and Dry air.

The heat and light which Earth recieves from Sun is insolation which stands for "incoming solar radiations". The radiations transmitted from Sun's body are solar radiations as solar stands for Sun.

An important gas in the atmosphere that absorbs sun's ultraviolet rays is Ozone. Ozone absorbs ultraviolet radiation but lets other types of radiation, such as visible light, pass through. The ozone gas throughout the stratosphere is called the ozone layer. It absorbs harmful ultraviolet radiation from the Sun.
