Final answer:
Vegetation plays a crucial role in protecting coastal areas from erosion and floods by intercepting raindrops, regulating water flow, and acting as a natural barrier against storms and tsunamis.
Step-by-step explanation:
Vegetation is a factor affecting coastal recession because it plays a crucial role in protecting coastal areas from erosion and floods. Vegetation plays a crucial role in protecting coastal areas from erosion and floods by intercepting raindrops, regulating water flow, and acting as a natural barrier against storms and tsunamis.
When there is dense vegetation, such as trees and mangroves, along the coast, it intercepts raindrops and reduces the direct impact on the soil, preventing erosion. Vegetation also helps regulate the flow of water, reducing the risk of flooding. Additionally, vegetation acts as a natural barrier against storm surges and tsunamis, absorbing their energy and reducing their impact on the coast.
