atmosphere & climatology section 3 MCQ Questions & Answers Detailed Explanation

Answer: (b)

The troposphere is the lowest layer of the Earth’s atmosphere. The air is very well mixed and the temperature decreases with altitude.

Answer: (b)

Convection rain commonly occurs in warmed or heated areas such as equatorial/tropical regions, where there is an almost daily occurrence and even distribution of rain, and temperate areas in summer.

It is also common in the inter-tropical convergence zone (ITCZ). It happens when the ground surface is locally overheated and the adjacent air, heated by conduction, expands and rises.

Answer: (d)

Answer: (a)

Our atmosphere has five layers- Troposphere, Stratosphere, Mesosphere, Thermosphere and Exosphere. The exosphere is the outermost layer of the atmosphere showing altitude about from 700 km to 10000 km above sea level.

This layer gradually and gradually merges in outer space having no atmosphere.

Answer: (b)

Mistral is a cold and dry strong wind that blows down from the north along the lower Rhone River valley toward the Mediterranean Sea in southern region of France.

Answer: (b)

The first statement is correct as we all know. One major factor affecting the distribution of the temperature of Earth is the distribution of Land and Oceans.

Since there is more land in Northern Hemisphere and more waters in the Southern hemisphere and there is a big difference between the specific heat of land and water; the loss of heat from the continents is bigger than the oceans.

The continents get heated faster and get cooled faster in comparison to the Oceans. This is the reason that the temperatures of the Oceans are moderate while that of continents is extreme.

The moderating effect on the temperature of the land due to the proximity of the seas is called Maritime influence. The increasing effect on the temperature of the land in the interior of the continents is called Continental Influence.
