beach area
sediment
rivers deposit sediment into beach
Erosion from rocks end up here
slope= what type of gran
steeper= finer sediment
waves go up the direction of wind but come straight down
Berms= accumulation of sediments
barrier Islands= shifting coasts in the ocean
Biological Influences affect the coasts
Coral reefs build up coasts
Estuaries= water fills up areas
river meets the ocean
Top Left: Salt Wedge
fast river hitting ocean
river goes over saltwater
Top Right: Partially Mixed
deepness allows to mix better
same as Well Mix
Bottom Left: Well Mix
mix well at every point
slower river and moderate - high tidal range
Bottom Right: Fjord
smaller surface area
u- shape valley
high river input
