refers to the vertical section of water from the surface to the sea bed

the most frequent wind direction a location receives

the sea dropping sediment (or material) being carried by the water at the coastline

The influence of sediment transportation and deposition on coastal landscapes

Geography

This unit teaches pupils about coastal processes and landforms. Pupils will learn about the physical processes operating at the coast and about the formation of distinctive landforms of coastal erosion and deposition. Pupils will also learn about the importance and options of coastal management.

Coastal landscapes

What process of sediment transportation is show in this diagram?

The most frequent wind direction a location receives is known as the {{}} wind direction.

Which of the following landforms is **not** caused by deposition at the coast?

Winds blow waves at an angle toward the coastline.

Sediment is transported along the shore by longshore drift.

When the coastline changes direction, sediment deposition continues.

Sediment builds up, forming a narrow landform that extends into the sea.

A sheltered area behind the spit forms and may become a saltmarsh.

Reorder the statement to explain how a spit is formed. 

Constructive waves have a stronger swash than backwash and build up beaches.

Constructive waves have equal swash and backwash, maintaining beach levels.

Constructive waves have a stronger backwash than swash and erode the coastline.

Constructive waves occur mostly during storms and erode the beach rapidly.

Constructive waves break frequently and move material offshore from beaches.

Identify the answer that correctly describes constructive waves.

What is the term used to describe the distance a wave has travelled?

Slate - formed when shale is heated and compressed by tectonic processes.

Basalt -  a volcanic rock that forms from rapidly-cooling lava.

Marble - formed when limestone is heated and compressed by tectonic processes.

Limestone - formed from layers of sediment compressed into rock.

Which of these is an example of a sedimentary rock?

Layers of more and less resistant rock are perpendicular to the coast.

Waves erode less resistant rock more quickly than more resistant rock.

Bays are eroded into less resistant rock, leaving headlands of resistant rock.

Reorder the statements to provide labels for these diagrams, from left to right.

Longshore drift moving sediment along the beach in direction of prevailing wind.

Destructive waves removing sediment from the beach.

A change in direction in the coastline (e.g. a river mouth).

No change in direction in the coastline (concordant coast).

Which of the following are required for a spit to be formed?

What process is being described when a loss of energy causes sediment being transported by waves to be dropped?
