The tread and the steeper descending slope (riser or scarp) together constitute the terrace. Terraces are formed in various ways.

What is a Marine Terrace quizlet?

What is a Sea Arch?

Arches form at headlands, where rocky coastlines jut out into the sea. Powerful waves pound into rock from both sides of the headland. The waves erode (wear away) the rock at sea level to form sea caves on either side. The waves eventually break right through the headland, creating an arch.

Is a marine terrace formed by erosion or deposition?

Marine terraces are formed by coastal erosion and reflect the history of the rise and fall of sea level over time. However, marine terraces are only found along coastlines where the land is rising. In areas where the land is sinking they are submerged or buried by younger sediments.

What causes alluvial terraces to form?

Alluvial terraces form when land slowly rises by pressure from tectonic forces. Each time the land is raised, a new floodplain forms. A succession of these events can produce step-like terrain, such as these stream terraces in New Zealand.
