Answer:
All of these statements are true. Coastal wetlands can absorb water from coastal flooding, act as a first line of defense against hurricanes and tsunamis, cleanse polluted waters, and protect shores from wave erosion.
Step-by-step explanation:
Coastal wetlands are highly effective at absorbing and storing water, which can help to reduce the impact of coastal flooding by slowing down the movement of floodwaters and allowing them to be absorbed into the soil. This can help to protect nearby communities and infrastructure from flood damage.
Coastal wetlands can also act as a first line of defense against hurricanes and tsunamis by helping to reduce the intensity of the storm surge and waves. The dense vegetation and complex root systems of wetlands can help to dissipate the energy of waves, reducing their destructive force.
In addition, coastal wetlands can help to cleanse polluted waters by filtering out sediments, nutrients, and pollutants from runoff and other sources. This can help to improve water quality and protect the health of coastal ecosystems.
Finally, coastal wetlands can protect shores from wave erosion by acting as a buffer zone between the ocean and land. The dense vegetation and root systems of wetlands can help to stabilize shorelines and reduce the impact of waves and currents, helping to prevent erosion and maintain the natural balance of coastal ecosystems.
