The correct answer is: d) All of the above
Bihar is a state in eastern India that is prone to floods. The state is located in the Ganges basin, which is a major river basin in South Asia. The Ganges River is the longest river in India and the third longest river in Asia. It is a major source of water for irrigation, drinking, and transportation in Bihar.
The monsoon season is the rainy season in India. It typically lasts from June to September. During the monsoon season, heavy rains can cause rivers to overflow their banks and flood surrounding areas. This can lead to loss of life, property damage, and disruption of livelihoods.
Bihar is also located in a seismically active region. Earthquakes can cause landslides and other damage that can lead to flooding.
Inadequate drainage systems can also contribute to flooding. When it rains, water needs to be able to flow away from homes and businesses. If the drainage system is not adequate, water can back up and cause flooding.
All of these factors contribute to the risk of flooding in Bihar. The state government has taken steps to mitigate the risk of flooding, but it is a challenge that the state will continue to face in the future.
Here is a brief explanation of each option:
- Heavy rainfall during monsoons: The monsoon season is the rainy season in India. It typically lasts from June to September. During the monsoon season, heavy rains can cause rivers to overflow their banks and flood surrounding areas. This can lead to loss of life, property damage, and disruption of livelihoods.
- Overflowing rivers: Bihar is located in the Ganges basin, which is a major river basin in South Asia. The Ganges River is the longest river in India and the third longest river in Asia. It is a major source of water for irrigation, drinking, and transportation in Bihar. During the monsoon season, heavy rains can cause rivers to overflow their banks and flood surrounding areas. This can lead to loss of life, property damage, and disruption of livelihoods.
- Inadequate drainage systems: When it rains, water needs to be able to flow away from homes and businesses. If the drainage system is not adequate, water can back up and cause flooding.
