What is a flood?

  1. A heavy rainfall that causes water to overflow an area of land.

  2. A prolonged period of dry weather that causes a shortage of water.

  3. A sudden release of water from a dam or reservoir.

  4. A rapid increase in the level of a river or lake.


Correct Option: A
Explanation:

Floods are caused by heavy rainfall that causes water to overflow an area of land. They can also be caused by the failure of a dam or levee, or by a sudden release of water from a glacier or snowpack.

What is a drought?

  1. A heavy rainfall that causes water to overflow an area of land.

  2. A prolonged period of dry weather that causes a shortage of water.

  3. A sudden release of water from a dam or reservoir.

  4. A rapid increase in the level of a river or lake.


Correct Option: B
Explanation:

Droughts are caused by a prolonged period of dry weather that causes a shortage of water. They can be caused by a lack of rainfall, or by high temperatures that cause evaporation to exceed precipitation.

What is the difference between a flood and a drought?

  1. Floods are caused by heavy rainfall, while droughts are caused by a lack of rainfall.

  2. Floods can cause loss of life and property, while droughts can cause crop failure and famine.

  3. Floods are a natural disaster, while droughts are a human-caused disaster.

  4. All of the above


Correct Option: D
Explanation:

Which country is most prone to floods?

  1. Bangladesh

  2. India

  3. China

  4. United States


Correct Option: A
Explanation:

Bangladesh is the most prone to floods due to its low-lying geography and the fact that it is located at the confluence of three major rivers: the Ganges, the Brahmaputra, and the Meghna.

Which country is most prone to droughts?

  1. Ethiopia

  2. Somalia

  3. Kenya

  4. Sudan


Correct Option: A
Explanation:

Ethiopia is the most prone to droughts due to its erratic rainfall patterns and the fact that it is located in the Horn of Africa, which is a region that is particularly vulnerable to climate change.

What is the most devastating flood in history?

  1. 1931 China floods

  2. 1970 Bhola cyclone

  3. 2004 Indian Ocean earthquake and tsunami

  4. 2011 Great East Japan earthquake and tsunami


Correct Option: A
Explanation:

What is the most devastating drought in history?

  1. 1930s Dust Bowl

  2. 1965-67 Great Plains drought

  3. 1980s Sahel drought

  4. 2010-12 East African drought


Correct Option: A
Explanation:

The 1930s Dust Bowl was the most devastating drought in history, causing widespread crop failure and economic hardship in the Great Plains region of the United States. The drought was caused by a combination of factors, including high temperatures, low rainfall, and poor farming practices.

How can climate change affect floods and droughts?

  1. Climate change can lead to more extreme weather events, including heavier rainfall and more intense droughts.

  2. Climate change can cause sea levels to rise, which can increase the risk of coastal flooding.

  3. Climate change can lead to changes in precipitation patterns, which can cause some areas to become wetter and others to become drier.

  4. All of the above


Correct Option: D
Explanation:

Climate change can lead to more extreme weather events, including heavier rainfall and more intense droughts. It can also cause sea levels to rise, which can increase the risk of coastal flooding. Additionally, climate change can lead to changes in precipitation patterns, which can cause some areas to become wetter and others to become drier.

What can we do to reduce the impact of floods and droughts?

  1. Invest in flood control and drought mitigation measures.

  2. Educate people about flood and drought risks.

  3. Develop early warning systems for floods and droughts.

  4. Promote sustainable land and water management practices.

  5. All of the above


Correct Option: E
Explanation:
