What is El Niño?

  1. A periodic warming of the central and eastern tropical Pacific Ocean

  2. A periodic cooling of the central and eastern tropical Pacific Ocean

  3. A periodic change in the atmospheric pressure patterns over the Pacific Ocean

  4. A periodic change in the ocean currents in the Pacific Ocean


Correct Option: A
Explanation:

El Niño is characterized by unusually warm ocean temperatures in the central and eastern tropical Pacific Ocean. This warming can have significant impacts on weather patterns around the world, including in India.

What is La Niña?

  1. A periodic warming of the central and eastern tropical Pacific Ocean

  2. A periodic cooling of the central and eastern tropical Pacific Ocean

  3. A periodic change in the atmospheric pressure patterns over the Pacific Ocean

  4. A periodic change in the ocean currents in the Pacific Ocean


Correct Option: B
Explanation:

La Niña is characterized by unusually cool ocean temperatures in the central and eastern tropical Pacific Ocean. This cooling can also have significant impacts on weather patterns around the world, including in India.

How do El Niño and La Niña affect the Indian monsoon?

  1. El Niño tends to weaken the Indian monsoon, while La Niña tends to strengthen it

  2. El Niño tends to strengthen the Indian monsoon, while La Niña tends to weaken it

  3. El Niño and La Niña have no significant impact on the Indian monsoon

  4. The effects of El Niño and La Niña on the Indian monsoon are unpredictable


Correct Option: A
Explanation:

El Niño tends to weaken the Indian monsoon by reducing rainfall, while La Niña tends to strengthen the monsoon by increasing rainfall. These effects can have significant implications for agriculture and water resources in India.

What are some of the agricultural impacts of El Niño and La Niña in India?

  1. El Niño can lead to droughts, while La Niña can lead to floods

  2. El Niño can lead to floods, while La Niña can lead to droughts

  3. El Niño and La Niña have no significant impact on agriculture in India

  4. The agricultural impacts of El Niño and La Niña in India are unpredictable


Correct Option: A
Explanation:

El Niño can lead to droughts in India by reducing rainfall, while La Niña can lead to floods by increasing rainfall. These extreme weather events can have devastating impacts on agricultural production and food security.

What are some of the water resource impacts of El Niño and La Niña in India?

  1. El Niño can lead to water shortages, while La Niña can lead to flooding

  2. El Niño can lead to flooding, while La Niña can lead to water shortages

  3. El Niño and La Niña have no significant impact on water resources in India

  4. The water resource impacts of El Niño and La Niña in India are unpredictable


Correct Option: A
Explanation:

El Niño can lead to water shortages in India by reducing rainfall and causing droughts, while La Niña can lead to flooding by increasing rainfall. These extreme weather events can have significant impacts on water availability and quality.

What are some of the natural disaster impacts of El Niño and La Niña in India?

  1. El Niño can lead to droughts and heat waves, while La Niña can lead to floods and landslides

  2. El Niño can lead to floods and landslides, while La Niña can lead to droughts and heat waves

  3. El Niño and La Niña have no significant impact on natural disasters in India

  4. The natural disaster impacts of El Niño and La Niña in India are unpredictable


Correct Option: A
Explanation:

El Niño can lead to droughts and heat waves in India by reducing rainfall and increasing temperatures, while La Niña can lead to floods and landslides by increasing rainfall and causing heavy storms. These extreme weather events can have devastating impacts on human populations and infrastructure.

How can India prepare for and mitigate the impacts of El Niño and La Niña?

  1. By investing in early warning systems and disaster preparedness measures

  2. By implementing sustainable agricultural practices and water conservation measures

  3. By reducing greenhouse gas emissions and transitioning to renewable energy sources

  4. All of the above


Correct Option: D
Explanation:

India can prepare for and mitigate the impacts of El Niño and La Niña by investing in early warning systems and disaster preparedness measures, implementing sustainable agricultural practices and water conservation measures, and reducing greenhouse gas emissions and transitioning to renewable energy sources. These measures can help to reduce the vulnerability of communities and ecosystems to extreme weather events.

Which of the following is NOT a characteristic of El Niño?

  1. Warmer than average sea surface temperatures in the central and eastern tropical Pacific Ocean

  2. Increased rainfall in India

  3. Droughts in Australia

  4. Floods in Peru


Correct Option: B
Explanation:

El Niño is typically associated with decreased rainfall in India, not increased rainfall. This is because El Niño tends to weaken the Indian monsoon, which brings rainfall to the region.

Which of the following is NOT a characteristic of La Niña?

  1. Cooler than average sea surface temperatures in the central and eastern tropical Pacific Ocean

  2. Increased rainfall in India

  3. Floods in Australia

  4. Droughts in Peru


Correct Option: B
Explanation:

La Niña is typically associated with decreased rainfall in India, not increased rainfall. This is because La Niña tends to strengthen the Indian monsoon, which brings rainfall to the region.

Which of the following is NOT a potential impact of El Niño on India?

  1. Droughts

  2. Heat waves

  3. Floods

  4. Wildfires


Correct Option: C
Explanation:

El Niño is typically associated with droughts and heat waves in India, not floods. This is because El Niño tends to weaken the Indian monsoon, which brings rainfall to the region.

Which of the following is NOT a potential impact of La Niña on India?

  1. Floods

  2. Landslides

  3. Droughts

  4. Wildfires


Correct Option: D
Explanation:

La Niña is typically associated with floods and landslides in India, not wildfires. This is because La Niña tends to strengthen the Indian monsoon, which brings rainfall to the region.

Which of the following is NOT a measure that India can take to prepare for and mitigate the impacts of El Niño and La Niña?

  1. Investing in early warning systems and disaster preparedness measures

  2. Implementing sustainable agricultural practices and water conservation measures

  3. Reducing greenhouse gas emissions and transitioning to renewable energy sources

  4. Ignoring the predictions and not taking any action


Correct Option: D
Explanation:

Ignoring the predictions and not taking any action is not a measure that India can take to prepare for and mitigate the impacts of El Niño and La Niña. This would leave the country vulnerable to the negative consequences of these climate phenomena.

Which of the following is NOT a region that is affected by El Niño and La Niña?

  1. India

  2. Australia

  3. South America

  4. Antarctica


Correct Option: D
Explanation:

Antarctica is not significantly affected by El Niño and La Niña because it is located in the Southern Hemisphere and has a different climate system than the rest of the world.

Which of the following is NOT a sector that is affected by El Niño and La Niña?

  1. Agriculture

  2. Water resources

  3. Natural disasters

  4. Manufacturing


Correct Option: D
Explanation:

Manufacturing is not typically affected by El Niño and La Niña because it is not directly dependent on climate conditions. However, the other sectors listed can be significantly impacted by these climate phenomena.

Which of the following is NOT a challenge that India faces in preparing for and mitigating the impacts of El Niño and La Niña?

  1. Lack of financial resources

  2. Lack of technical expertise
