  1. Coastal Landforms A Visual Dictionary

  2. Spit Created by deposits of sand where the sea current slows down A long thin point of land made of sediments

  3. Barrier Bay A bay cut off the open water by a spit that has closed the mouth of the bay.

  4. Barrier Island A long thin Island parallel to the shore formed of sediments deposited by waves and rivers. Sometimes left by glacials processes

  5. BEACH A coastal area covered in loose (unconsolidated) sediments (sand or gravel)

  6. Delta A landform created where a river dumps more sediment than waves and currents can spread out. The river often braids. This is the MacKenzie River Delta.

  7. Headland An arm of rocky cliffs sticking out into open water. The headlands are “high energy” zones where wave energy is concentrated and erosion is a major force shapping cliffs, caves, arches and sea stacks.

  8. Sea Arch Arches in rocks where the waves have worn a hole through the headland, while the rock above hole stays together.

  9. Sea Stack Created when the roof of arched holes in the headland break off and fall. There is a headland, then a gap and then a tower of standing rock.

  10. Cliff Steep faces of rock where erosion and waves have cut away the bottome of the land, causing the rock above it to fall.

  11. Beach Beaches are formed by both EROSION (wearing away) and DEPOSTION (building up).

  12. Beach Wave action against cliffs and beach faces is an continuing process that breaks rock into smaller pieces where are worn and ground down on the beach as the waves roll and grate rocks together making them smoother and smaller.
