Propping Up the Coastline!

Short answer: Mangroves grow along tropical and subtropical coasts. Their tangled above-ground prop roots and dense vegetation create friction that slows water and absorbs wave energy, reducing erosion and protecting shorelines and settlements from storm surge.

Video transcript: Propping Up the Coastline!: Mangrove Roots Slow Incoming Waves Before They Reach Shore

Mangroves absorb waves through their complex root systems and dense vegetation, which provide natural barriers along coastlines. The above-ground roots known as prop roots extend into the water and create friction, slowing down wave energy. This helps to dissipate the force of incoming waves, reducing erosion and protecting shorelines. NOW YOU KNOW!
