sandy coast.

6. occur where deposition (settlement) of sediments is creating sandy beaches
7. (clams, coquinas, cockles) use a muscular foot to bury themselves, feeding through a siphon that reaches up the surface
8. zone, or the intertidal zone →the tide comes and goes here
14. species can tolerate a range of salinities
15. Behind the barrier islands are estuaries - partially enclosed, coastal water bodies (bays, sounds, lagoons, etc)
16. renourishment is the process of dredging and pumping sediment from just offshore up onto the beach to increase the width of the beach
17. reefs Oysters grow together in clumps and may form oyster reefs
18. freshwater from rivers and streams mixes with salt water from the ocean to form brackish water

1. Ghost crabs dig burrows above the high tide line, and crawl to the water to feed when dark
2. interrupt or redirect the longshore current, and keep sand bars from filling in passes between barrier islands
3. water enters between the barrier islands, at a pass or inlet
4. a thin strand of sand that connects two pieces of land
5. spit a thin strip of sand that extends out from a beach
9. flow parallel to the coast
10. Along the U.S. east coast, mangroves are the dominant coastal vegetation in tropical regions
11. beds are common - they absorb nutrients from the water, stabilize the seafloor with their root systems, and clarify water, physically and chemically
12. is the transportation of sediments along a coastline as a result of the longshore current
13. islands form as waves repeatedly deposit sediment parallel to the beaches
