The correct answer is: All of the above.
Poverty can worsen the effects of natural hazards in a number of ways. People living in poverty are more likely to live in areas that are at risk of natural hazards, such as floodplains or areas prone to landslides. They are also less likely to have access to resources that can help them to cope with a natural hazard, such as insurance, safe housing, and early warning systems.
Lack of infrastructure can also worsen the effects of natural hazards. For example, if a community does not have a well-functioning drainage system, a flood can cause more damage. Similarly, if a community does not have a reliable power supply, a power outage can make it difficult to communicate during a disaster.
Population density can also worsen the effects of natural hazards. If a large number of people live in a small area, a natural hazard can cause more damage and loss of life. This is because there are more people who are at risk, and it can be more difficult to provide assistance to those who are affected.
In conclusion, the effects of natural hazards can be worsened by poverty, lack of infrastructure, and population density. These factors can make it more difficult for people to cope with a natural hazard, and they can also increase the risk of death and injury.
