The groups waves travel in.

The breaking waves

A landform that is formed when waves erode and undercut rock to produce steep slopes.

Offshore columns of resistant rock that were once connected to the mainland. In these instances, waves have eroded the mainland, leaving behind isolated columns of rock.

Landforms that result from when wave action continues to erode a sea cave, cutting completely through the rock.

Landforms that result from waves cutting large holes into fractures or weak rock along the base of sea cliffs. Sea caves are common in cliffs composed of sedimentary rock.

Finger-shaped projections that form when cliffs made of hard rock erode more slowly than surrounding rock. On many shorelines, hard rock will form headlands, and the softer rock will form beaches or bays.

Landforms that result from a sea cliff that is worm back, producing a nearly level platform beneath the water at the base of the cliff.

An underwater or exposed ridge of sand, gravel, or shell material.

An exposed sandbar that is connected to the shoreline.

How is sand made?

The waves beat against the rock, and over time erode the surface into smaller rocks that eventually become sand.

Why is more shoreline eroded during storms than during nice weather?

The force of waves during a storm is greater than the force of the waves during nice weather.

How do sand, rock fragments, dead coral, and shells end up on the shoreline? Why do different beaches look so different?

The waves deposit these materials, and different ocean produce different materials.

How are barrier spits and sandbars created?

Sandbars and barrier spits are created by waves moving at an angle to the shoreline push water along the shore and create longshore currents. When waves erode material from the shoreline, longshore currents can transport and deposit this material (sand, rocks, gravel, coral) offshore.

What are six shoreline features created by wave erosion?

Sea cliffs, sea stacks, sea caves, sea arches, handlands, and wave-cut terraces.
