Transport by the sea
The shingle carried by the sea is called load
Or
Load is moved:
Up the shore by the force if moving incoming waves and back down the shore
Along the shore by Longshore drift
Longshore drift
Waves approach the shore from the side
Swash pushes up the beach at an angle
Each backwash drags some of the material straight into the sea
As process repeats, material is transported along the sea in a zig-zag motion
Grounds
Low walls built the stop Longshore Drift
Sea deposition
The sea drops it’s load where the power of the wave is reduced
Beaches
Smash pushes material up the beach. Backwash carried some of the load back
Sand dunes
Large mounds at the back of beaches formed by the wind. Marram grass is planted in the sand dunes to prevent the sand invading near by land
Spits
Formed by Longshore Drift. A narrow ridge of sand juts out into the sea while the other is connected to the land. Made of shingle. Port marnock. Co. Dublin
Bars
A spit may grow until it reaches the other side so the bay, former spit now known as Bar. A lagoon is a small artifice lake that gets trapped behind the bar. E.g. Lady’s Island Lake, co. Wexford
Tombolos
Narrow ridge of sand and shingle that joins an off shore island to the main land. A spit may grow in length until it reaches a near by island. Howth, Co. Dublin joins to Sutton
