| It refers to the movement of waves form the sea to land (or shore). |

Definition
| It refers to the movement of waves from the shore back to the sea |

Definition
| They are created in storm conditions. They are created in strong waves when the wind is powerful They occur when wave energy is high. They erode the coast. They have a strong backwash, than swash |
|
|
Term
|
Definition
| They are created in calm weather and are less powerful than destructive waves. They deposit material, building up beaches. They have a swash that is stronger than the backwash. They have a long wave length and are low in height. |

|
Term
|
Definition
| It is the wearing away and breaking up of rock along the coast. They are caused by the actions of waves (backwash and swash) |
|
|
Term
|
Definition
| It is from the force of the water hitting the cliffs |
|
|
Term
|
Definition
| It is cause by the waves picking up stones and hurling them at the cliffs |
|
|
Term
|
Definition
| As the materials are carried by the waves they begin to hit each other until they become rounder and softer over time |
|
|
Term
|
Definition
| The dissolving of rocks by seawater |
|
|
Term
|
Definition
| The wave actions on the coast line causes rocks to wear of irregularly. The softer rocks are worn back into "bays" while the harder rocks as headlands |
|
|
Term
|
Definition
| It is a steep rock facing the coast |
|
|
Term
|
Definition
| It takes place when large waves breaks against the foot of the cliff creating a wave-cut notch. Over a period of time, the notch enlarges until the cliff above it collapses, forming the platform |
|
|
Term
|
Definition
| It is formed when waves force the way into the cliff face. The water contains sand and other materials that hit the rock until the crack widens into it |
|
|
Term
|
Definition
| It is formed when the cave widens and the sea cuts through |
|
|
Term
|
Definition
| It is form when the waves erodes the foot of the arch, the roof becomes too heavy to be supported thereby collapsing to a stack |
|
|
Term
|
Definition
| It is formed when waves continue to erode the stack |
|
|
Term
|
Definition
| It is a process by which the transported materials accumulate |
|
|
Term
|
Definition
| It is formed when the four process(hydraulic action, corrasion, attrition and corrosion) will carry particles and deposit them along the coast. |
|
|
Term
|
Definition
| It is a long narrow stretch of sand with one end facing the sea and the main land |
|
|
Term
|
Definition
| It is developed when a spit stretches across a bay linking two headlands |
|
|
Term
|
Definition
| It is formed when a spit joins an offshore island |
|
|
Term
|
Definition
They are formed due to erosion of surface hard rocks and under soft rocks as a result of running water. The vertical movement of water creates a plunge pool
The soft rock is eroded while the hard rock that sticks out collapses due to gravity |
|
|
Term
|
Definition
| It is a deep sided valley left behind when a waterfall retreats |
|
|
Term
|
Definition
| It is a form of coastal defense constructed where the sea is, to protect areas of human habitation, conservation and leisure activities from the actions of tide and waves |
|
|
Term
|
Definition
| It is the process of repairing the beaches using materials such as sand and mud form inland |
|
|
Term
|
Definition
| It is a kind of coastal defense built into the sea to slow the movement of materials along the coast and help protect the beach |
|
|
Term
|
Definition
| It is the use of different rock types and concrete blocks to protect coastal lines from erosion by the sea, rivers or streams |
