Oceanography Chapter 10- Beaches and Coastlines

shore

zone that lies between the lowest tide level and the highest land elevation that storms impact

coast

extends inland as far as ocean-related features

coastline

boundary between coast and shore

backshore

high tide to storm line, only covered w/ water during storms

foreshore

submerged at high tide and exposed at low tide

nearshore

low tide to breakers, never exposed

shoreline

line where the land meet the ocean, dependent on where the water currently is

offshore

beyond the breaking waves

beach

strip of land formed by sediment deposits that were carried by the waves

berm

the dry, gently sloping, slightly elevated margin of the beach

beach face

the wet, sloping surface that extends from the berm to the shoreline

longshore sandbar

sand bars that run parallel to the coast, typically submerged in the water

longshore trough

a submerged channel located between a longshore sandbar and the beach face parallel to the coast

Land to ocean (shore)

coast → backshore → foreshore → nearshore → offshore

Land to ocean (beach)

berm → beach face → longshore trough → longshore bar
