Climate And Weather In Indian Geography MCQ Question and Answer | Geography MCQ Question

The retreating monsoon withdraws itself from North-West India to Bengal and then to Kerala. When the retreating monsoon blows from the northeast across the Bay of Bengal, it picks up a significant amount of moisture, which is subsequently released after moving back onto the peninsula.

In May-June each year, the monsoon winds approach the southern tip of India from South-westerly direction because winds blow from high to low pressure, warm moisture-laden air moves south-westerly direction from the sea over to India in the north and North East and is deflected by the Coriolis force as the Earth spins. It is this moist air current which is popularly known as the south-west monsoon.

The premonsoon mango showers occur predominantly in Kerala and Karnataka. These showers are a meteorological phenomenon that marks the onset of the southwest monsoon season in India. The southwest monsoon winds bring moisture-laden air from the Arabian Sea to the Indian subcontinent. As this moist air encounters the Western Ghats, it is forced to rise, cool, and condense, leading to the formation of premonsoon showers.

Kerala and Karnataka are the states located along the western coast of India, adjacent to the Western Ghats. The geography of this region, with the presence of the Western Ghats, makes it conducive for the occurrence of these early rain showers before the onset of the full-fledged monsoon. These showers are vital for agricultural activities, especially for the cultivation of crops like mangoes.

The main reasons for the origin of the south-west monsoon in India are Development of a low pressure in north-west India and Deflection of trade winds. These winds originate in the Southern Hemisphere, cross the Equator (trade winds) and gets deflected to the right by the Coriolis force in the Northern Hemisphere.

Indian monsoon is marked by seasonal shift caused by differential heating of land and sea. The climate of India depends greatly on monsoon winds. The monsoons usually happen due to the differential heating of land and water. Normally, there is high pressure in the tropical eastern-south Pacific Ocean and low pressure in the tropical eastern Indian Ocean.

The onset of the monsoon in India typically begins with the arrival of the southwest monsoon over the southernmost state, Kerala, and then progresses northwards.

West Bengal (3): West Bengal, being located in the eastern part of India, usually experiences the onset of the monsoon earlier than states further west or north.

Kerala (2): Kerala, situated in the southern part of India, is usually the first state to experience the onset of the southwest monsoon.

Uttar Pradesh (1): Uttar Pradesh, being located in the northern part of India, typically experiences the onset of monsoon after West Bengal and Kerala but before states further west like Rajasthan.

Rajasthan (4): Rajasthan, being situated in the western part of India, usually experiences the onset of monsoon after other states due to its geographical location.

Therefore, the correct order of the states based on ascending dates of the onset of monsoon is Option B: 3-2-1-4.

The statement that is true with regard to the erratic behaviour of Indian monsoons is Uncertain date of onset and withdrawal as well as varying amounts of rainfall during different years.

Gujarat accounts for over 70% of the production in country. The availability of favourable conditions such as arid climate with low rainfall and low relative humidity contributes largely towards salt production in the region. e.g. Sambhar Lake.

National Flood Commission also called as "Rashtriya Barh Ayog" was established in 1976 to evolve a coordinative, integral and scientific approach to the problems arising in controlling floods in the country and to strategise a national plan to fix priorities so as to implement them in the future.

The correct sequence in the decreasing order of contribution to the forest cover on India is Open forest - Dense forest - Mangrove forest.
