The winds flowing from high-pressure area toward the Mediterranean sea are-
Correct Answer:
(B)
Trade wind
The Mediterranean Sea is located between 30°- 40° latitude. This area is under a subtropical high-pressure dynamic belt. Summer trade wind and westerly(anti-trade) winter wind blows from this latitude. It means Westerly blows from this latitude toward the north-east and trade wind flows from this latitude toward north-west.

The seasonal reversal of winds is the typical characteristic of –
Correct Answer:
(C)
Monsoon climate
Monsoon are those seasonal winds whose direction reverses as per the season. For six months during summer, these winds flow from ocean to land and during the winter season, these winds flow from land to sea. According to Dr. Rama Shastry, "Monsoonal winds blow on a large scale over an expanded region. Their direction reverses as per the change in season. According to Dr. H.G . Dubey," Reversal of wind system is the keynote of monsoonal climate. Hence, option (c) is the correct answer.

Which one of the following pairs is not correctly matched?
Correct Answer:
(C)
Mistral - Rhine Valley
Mistral is a cold wind blowing in the southern region of France. It is strong in the winter and spring season. It blows along the Mediterranean coast from northern Spain to northern Italy. It is more frequently in the lower Rhone valley. It is purely a Katabatic wind that flows at a speed of 130 kph. Thus option (c) is not correctly matched. Other options are correctly matched.

Given below are two statements one labelled as Assertion (A) and the other labelled as Reason (R).
Assertion (A) : Areas lying within five to eight-degree latitude on either side of the equator receive rainfall throughout the year.
Reason (R) : High temperature and high humidity cause convectional rainfall mostly in the noon near the equator.
By using the codes given below, select the correct answer:
Code:
(A) and (R) are true, and (R) is the correct explanation of
(A)
Correct Answer:
(A)
and (R) are true, but (R) is not the correct explanation of
The climatic region of equatorial line spreads between 50 -100 latitudes in both the hemispheres. There are two important features of this climatic region:
(1) Constant high temperature throughout the year.
(2) Constant high rainfall throughout the year. Hence, assertion (A) is correct.
Due to high temperature throughout the year, there is high humidity which results in conventional rains mostly in noon. As the day progresses, the intensity of rain gets reduced. Hence, (R) is also correct and (R) is the correct explanation of (A).

Which of the following continents has all types of climatic zones?
Correct Answer:
(D)
Asia
Earth is divided into three types of climatic zones – Tropical, temperate and cold. These spread from the equatorial line to the poles. Asia is expanded from the Equator to the North Pole; hence it is home to all types of climatic zones.
