1. Wave Erosion
16.2 Review

2. Headlands Resistant rock left that projects into the ocean
Typically granites or very very resitant sandstone

4. Sea Caves

5. Sea Arch

6. Sea Stacks
Offshore isolated columns of rock that were once attached to a headland

7. Shoreline Erosion- large waves during storms hit the shore so hard that it pulls the rock off and into the ocean.
Sea Cliffs- a steep structure of rock located where waves strike directly against rock.
Sea Caves, Arches, and Stacks-large holes along the base of a sea cliff, offshore isolated columns of rock.
Terraces- a level platform underneath the water at the base of a sea cliff.
- Wave-cut terrace
Wave-built terrace-an extension of a wave-cut terrace.

9. Terraces
Wave-cut- when sea cliffs retreat, terraces are built due to erosion by waves
wave-built- due to material being eroded away from retreating terraces, those deposits may accumulate to build terraces

12. Coastline and sea level changes-the sea level rises and falls depending on the amount of ocean water.
Coastline and Land Changes- Coastlines can be flooded if land sinks, and can be exposed if the land rises.
Submergent Coastlines- formed when the sea level rises or land sinks. Inlets between land.
Emergent Coastlines- formed when land rises or sea level falls.

13. Ancient wave-cut terraces

14. Beaches- depositions of sand along an ocean shore.
-composition depends on the source rock.
Berm- the raised section on most beaches.
Sand Bar- underwater ridges.
Longshore-Currents are created by waves moving at an angle to the shoreline push water along the shore.
Spit- a long narrow deposit do sand at one end of the shore.
Tombolos-connections from offshore islands to main lands.

15. Green Sand?

16. Longshore currents

19. Barrier Island- long narrow offshore ridges of sand.
Coral Reefs- coastal features that are homes to small marine animals that live in warm shallow sea water.
-fringing reef-around the coast of an island.
-barrier reef-coral offshore around the remaining of the volcano.
-atoll-circular coral reef surrounding a shallow lagoon.
