El Nino becomes La Nina when El Nino ________.

  1. Warms up

  2. Cools

  3. Both a and b

  4. None of these

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

El Nina becomes La Nino when El Nino cools. La Nina is a counter ocean current which becomes effective in the Tropical Western Pacific when El Nino becomes ineffective in the Tropical Eastern Pacific. The dry condition in the western Pacific is terminated and the wet condition is introduced in the Tropical Western Pacific by Later Nina.

A Correct answer
Explanation

The hurricane impacts of El Niño and its counterpart La Niña are opposite and alternating between the Pacific and Atlantic oceans, strengthening hurricane activity in one region while weakening it in the other. However, the effect is limited to the climate of the tropics and subtropics.

Which of the following does not have an influence over the climate on India?

  1. Monsoons

  2. Nearness to equator

  3. Ocean currents

  4. Presence of Indian ocean

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Ocean currents does not have influence over the climate in India. Ocean currents act much like a conveyer belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface.

Which of the following does not have influence over the climate of India?

  1. Nearness to Equator

  2. Presence of Indian Ocean

  3. Monsoons

  4. Ocean currents

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The climate of India is primarily influenced by its location relative to the Equator, the presence of the Indian Ocean, and the seasonal monsoon winds. Ocean currents do not have a direct or significant impact on the climate of the Indian subcontinent compared to these other factors.

The western disturbances which cause winter rain in India originate in _____.

  1. Pakistan

  2. Bay of Bengal

  3. West Asia

  4. Himalayas

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
West Asia.
Western Disturbance is an extratropical storm, which give rain to North and Northwest India during winter. It is very useful for wheat and winter crops. It is driven by westerlies (westerlies, are prevailing winds from the west toward the east in the middle latitudes between 30 and 60 degrees latitude.)
Western Disturbances originate from the Mediterranean sea, the Black sea, and the Caspian sea. From this region and from Atlantic ocean they collect the moisture and move eastward.

In the extratropical zone frontogenesis (a process in which two air masses of different densities come together to form a front) process take place which in turn facilitates the formation of the cyclone. These types of cyclones occurring over mid-latitude are called extratropical cyclones. They travel as a family and reaching north India one by one.  They are more in frequency in the winter season as westerlies are stronger in winter. They approach India by traveling across Iraq, Iran, Afghanistan, and Pakistan. They are mainly lower tropospheric systems that show variation in strength and vertical extent with superimposition of a mid and upper tropospheric trough in westerlies.

How do the western disturbances affect the crops in north India?

  1. They cause heavy damage to the standing crops

  2. They bring in locusts which destroy the crops

  3. They are beneficial to the crops by causing winter rain

  4. They help in keeping the plants warm to some extent in winter

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

They are beneficial to the crops by causing winter rain.
They are the cause of most winter and pre-monsoon season rainfall across northwest India. Precipitation during the winter season has great importance in agriculture, particularly for the rabi crops.  Excessive precipitation due to western disturbances can cause crop damage, landslides, floods and avalanches.
