Heavy rainfall is a common cause of floods. When the amount of rainfall exceeds the capacity of the land or drainage systems to absorb or carry away the water, it leads to the overflowing of rivers, inundation of low-lying areas, and the occurrence of floods.

Test: World- Natural Disasters - Question 6

Which strategy helps in mitigating the impacts of earthquakes?

Detailed Solution for Test: World- Natural Disasters - Question 6

Early warning systems play a crucial role in mitigating the impacts of earthquakes. These systems provide alerts and timely information to people in earthquake-prone areas, allowing them to take preventive measures, evacuate if necessary, and reduce potential casualties and damages.

Detailed Solution for Test: World- Natural Disasters - Question 7

Building codes in areas prone to hurricanes primarily aim to ensure wind resistance. These codes specify design and construction standards that buildings must adhere to in order to withstand the strong winds associated with hurricanes, reducing structural damage and enhancing the safety of occupants.

Test: World- Natural Disasters - Question 8

Which measure helps in managing flood risks?

Detailed Solution for Test: World- Natural Disasters - Question 8

Implementing floodplain zoning is a crucial measure in managing flood risks. Floodplain zoning involves identifying areas prone to flooding and regulating land-use activities accordingly, such as restricting construction in high-risk areas and promoting green spaces or retention ponds to absorb excess water.

Test: World- Natural Disasters - Question 9

What is the significance of reforestation in flood management?

Detailed Solution for Test: World- Natural Disasters - Question 9

Reforestation plays a significant role in flood management. Trees and vegetation help improve water absorption, reduce surface runoff, stabilize soils, and prevent erosion. This can help mitigate the impact of floods by reducing the volume and speed of water flowing into rivers and streams.
