coasts

• coasts

  • the zone where the land meets the sea
• erosion

  • the wearing away of a surface (eg.cliff) and removal of sediment (destructive process)
• corrosion/abrasion

  • waves carry rocks like cobbles, pebbles and gravel and when they hit the coast and break the rocks forming the coast
• attrition

  • rocks carried by the waves are thrown against each other
• solution

  • soluble mineral in rocks dissolve and rocks weaken and disintegrate and broken
• hydraulic action

  • the weight of the waves when they smash/hit repeatedly causing rock surfaces to weaken and loose rock to fall out
• sediment

  • material at the coast such as sand, rocks, and pebbles
