Given below are two statements, one is labelled as Assertion (A) and other as Reason (R).
Assertion (A): India has a tropical Monsoon type climate.
Reason (R): India is located exactly between the tropical latitudes.
Code:
(A) and (R) are true, and (R) is the Correct explanation of
(A).
Correct Answer:
(B) and (R) are true, but (R) is not the correct explanation of
The climate of India is tropical monsoonal and it is situated between 8o4' to 37o6' north latitudes. It is not situated between tropical latitude i.e., 23o30' north to 23o30' south latitudes. So, (A) is correct and (R) is false.
Ques: 2
In which of the following States does the Monsoon arrive first?
Correct Answer:
(D)
Kerala
In India, monsoon arrives first in Kerala. India receives 91 percent of its total rainfall from south-western monsoon which starts from Kerala and is active from June to September every year.
Ques: 3
The general direction of flow of summer monsoon in India is –
Correct Answer:
(D)
From South West to North East
In summer, the monsoon flows from South West to North East direction. During winter while retreating back, it flows from North East to South- West direction. Maximum rainfall in India occurs due to south-west monsoon.
Ques: 4
High temperature and low pressure over the Indian Subcontinent during the summer season draws air from the Indian Ocean leading to the in-blowing of the:
Correct Answer:
(B) South West monsoon
The south -west monsoon is responsible for most of the rainfall in India. It is caused due to high temperature and low pressure over the Indian subcontinent during the summer season which draws air from the Indian Ocean.
Ques: 5
Which are the months for monsoon normally in Tamil Nadu?
Correct Answer:
(D)
November-December
The period of October to December is referred to as North East Monsoon season over Peninsular India. It is the period of rainfall over South India, particularly in Andhra Pradesh, Rayalaseema and Tamil Nadu. This is the main rainy season in Tamil Nadu region. During this monsoon on 26 December, 2004, Tamil Nadu was struck by Tsunami. So, the answer is (d).
Ques: 6
The Indian monsoon is indicated by seasonal displacement because of
Correct Answer:
(A) Differential temperature of land and sea
The Indian monsoon is indicated by seasonal displacement because of the differential temperature of land and Sea. Some of the important concepts about the origin of Monsoon are:
Thermal concept: It propounds that the primary arrival of the annual cycle of the Indian monsoon circulation is the differential heating effect of the land and the Sea.
Dynamic Concept: Put forward by Flohn, according to this concept, monsoon is the result of seasonal migration of planetary winds and pressure belts.
Ques: 7
Which of the statement(s) given above is/are correct?
1. The duration of the monsoon decreases from southern India to northern India.2. The amount of annual rainfall in the northern plains of India decreases from east to west.
Correct Answer:
(C) 1 and 2
The amount of rainfall decreases from east to west owing to the progressive decrease in the humidity of the winds. The Southern part of India being near to sea gets rainfall early and for a longer duration than the northern part. Thus, both the statements are correct.
Ques: 8
Which of the following regions is not affected much by the Arabian Sea branch of Monsoon?
Correct Answer:
(D)
Chhattisgarh Basin
Chhattisgarh basin is not affected much by the Arabian sea branch of monsoon. Arabian sea branch monsoon further split into two branches after being obstructed by the Western Ghats. First branches move parallel to Aravali range causing scanty rainfall further mingles with the Bay of Bengal branch in North India. The second branch after being obstructed by Vindhya Mountain causes rainfall in Gujarat, Madhya Pradesh and western Chhattisgarh. Therefore, it is clear that the Chhattisgarh basin is not much affected by the Arabian sea branch of monsoon.
Ques: 9
India gets maximum rainfall mainly from –
Correct Answer:
(C) South-West Monsoon
During April and May when the Sun Shines vertically over the Tropic of Cancer, the large land mass in the north of Indian Ocean gets intensely heated. This causes the formation of intense low pressure in the northwestern part of the subcontinent followed by the northward shift in the position of Inter Tropical Convergence Zone (ITCZ). The south-west monsoon may thus, be seen as the continuation of the southeast trades deflected towards the Indian subcontinent after crossing the Equator. Southwest monsoon enters India in two rain-bearing systems. First originates in the Bay of Bengal causing rainfall over the plains of north India. Second is the Arabian Sea current of the south-west monsoon which brings rain to the west coast of India. According to data provided by Indian Meteorological Department for the year 2019, south-west monsoon supplies over 110% of India's annual rainfall.
Ques: 10
The state which receives maximum rainfall due to North-East monsoon is
Correct Answer:
(C) Tamil Nadu
Tamil Nadu, located in south-east peninsular India, receives the major part of its annual rainfall during the North East monsoon season. Tamil Nadu receives about 50-60% of its annual rainfall during Northeast monsoon.
