Coasts

Coasts

1. Constructive

   • Bigger the wave the more eroded material it will contain and the build up the beach

2. Destructive

   • The Bigger the Back wash the more the beach will erode and the eroded material will go into the sea
   • Corrosion - Acids contained in the sea water will slowly disolve certian types of rock
   • Abraison - Waves bring with them bits of rock and and these help to grind down cliffs
   • Hydrulic Action - Waves cause rocks and pebbles onto the shore to smash against one another they are worn down into smaller more rounded pieaces
   • Attriton - This means the consitant force of waves crashing on the shore changes it
