B) Put sandbags along the coastline.
C) Build a fence along the coastline.
D) Plant more grass near the coastline.

Answer 1

Answer:

D) Plant more grass near the coastline.

Explanation:

    Vegetation cover acts as soil protection against the action of raindrops through the interception of water by the vegetation structure located above the ground surface, which reduces the raindrop velocity and partially removes the intensity of the splash effect. It is responsible for causing aggregate rupture and sealing the soil surface, in addition to structuring the soil by dispersing its roots, which can increase the infiltration capacity and reduce the intensity of runoff and erosion processes resulting from it. In tropical forests, 4.5 to 24% of rain is intercepted by vegetation, with 1 to 2% of the remainder flowing through their trunks, indicating that 75 to 96% of external precipitation reaches the soil surface.

Answer 2

D) Plant more grass near the coastline. this would preserve it
