Answer: D

Explanation:

Due to the long coastline, temperate climate is found in the vast coastal areas of India. The interior parts of India are deprived of the equalizing effect of the sea. Extreme climate is found in such areas. This is the reason why the residents of Mumbai and Konkan coast are not able to experience the temperature differences and seasonal changes. Hence, statement 1 is incorrect

Seasonal changes affect the entire life in interior parts like Delhi, Kanpur and Amritsar. In these areas, there is more variation in temperature, due to which people have to face heat in summer and cold in winter. Seasonal changes happen frequently, due to which people have to change clothes and other necessities. Agriculture and other economic activities are also affected due to weather. Hence, statement 2 is incorrect.

Answer: B

Explanation:

Jet flow is a type of wind which occurs at a height of 9 to 13 km all over Central and Western Asia under the influence of westerly winds blowing from west to east. They move near the surface or in the lower layers of the atmosphere. A completely different type of air circulation occurs in the troposphere of the lower atmosphere, about three kilometers above the surface. Hence, statement 1 is correct.

The jet stream is formed due to the Coriolis force due to the Earth's rotation. Coriolis force is a force caused by the Earth's rotation that exerts force on a moving object in a direction perpendicular to its axis. Hence, statement 2 is correct.

These winds blow on the Asian continent north of the Himalayas, parallel to the Tibetan plateau. These are called jet flows. The Tibetan highlands act as a barrier to these jet streams, as a result of which the jet stream gets divided into two parts. One of its branches flows in the north of the Tibetan plateau. The southern branch of the jet stream flows eastwards south of the Himalayas. The average position of this southern branch in February is about 25° above the north latitude line and its pressure level is 200 to 300 millibars. It is believed that this southern branch of the jet stream has a significant impact on the winter weather in India. Hence, statement 3 is incorrect

Answer: A

Explanation:

The direction of the hills in the eastern hills and mountain part of the Himalayan Mountains is from north to south. These hills are known by various local names. In the north these are known as Patkai Boom, Naga Hills, Manipur Hills and in the south as Mizo or Lusai Hills. This is an area of ​​low hills where many tribes practice 'Jhum' or Shifting cultivation. Most of the hills here are separated by small and big rivers. Barak is a main river of Manipur and Mizoram. There is a lake situated in the middle of Manipur valley which is called 'Loktak' lake and it is surrounded by hills on all sides. Hence, option (a) is the correct answer.

Answer: B

Explanation:

In the late 19th century, it was explained that differential heating of land and sea during the summer months sets the stage for the sub-continental movement of monsoon winds. In the months of April and May, when the Sun shines vertically over the Tropic of Cancer, the vast land area to the north of the Indian Ocean becomes extremely hot, resulting in the development of an intense low pressure area over the northwestern part of the subcontinent, Because the Indian Ocean in the south of the landmass warms relatively slowly, the low pressure center attracts south-easterly winds from across the equator. Hence, statement 1 is correct.

In these conditions the inter-tropical convergence zone shifts northwards. Thus, the south-west monsoon winds can be seen as an extension of the south-east easterly winds, which cross the equator and get deflected towards the Indian subcontinent. These winds cross the equator between 40° East and 60° East longitude lines. Hence, statement 2 is incorrect.

Answer: B

Explanation:

Kashmir Himalayas has some important freshwater lakes (freshwater lakes) like Dal Lake and Wular Lake and brackish water lakes (saltwater lakes) Pangong Tso and Somuriri Lake. Hence, pairs 1 and 3 are correctly matched.
