What causes erosion in beaches?
Coastal erosion may be caused by hydraulic action, abrasion, impact and corrosion by wind and water, and other forces, natural or unnatural. Also abrasion commonly happens in areas where there are strong winds, loose sand, and soft rocks. The blowing of millions of sharp sand grains creates a sandblasting effect.

What type of erosion is abrasion?
Abrasion is a process of erosion which occurs when material being transported wears away at a surface over time. It is the process of friction caused by scuffing, scratching, wearing down, marring, and rubbing away of materials. Objects transported in waves breaking on coastlines cause abrasion.
How are coastal communities dealing with beach erosion?
Coastal communities have been battling beach erosion for years. They often dredge, or pull in sand from offshore to fill in the beaches. This helps for a while but is not permanent. They may also build walls to prevent water from reaching houses near the beach.
