What are the 4 processes of coastal erosion?
What are the 4 processes of coastal erosion?
Destructive waves erode through four main processes; Hydraulic Action, Compression, Abrasion and Attrition.
What are the 4 processes of coastal transportation?
These are:
- Solution – when minerals in rocks like chalk and limestone are dissolved in sea water and then carried in solution.
- Suspension – small particles such as silts and clays are suspended in the flow of the water.
- Saltation – where small pieces of shingle or large sand grains are bounced along the sea bed.
What are the 4 different types of erosion?
Rain, rivers, floods, lakes, and the ocean carry away bits of soil and sand and slowly wash away the sediment. Rainfall produces four types of soil erosion: splash erosion, sheet erosion, rill erosion, and gully erosion.
What are the various types of coastal processes?
Eroding cliffs and offshore continental shelf sediment also provide sources of materials for the coast. Other processes which influence the coastal environment include longshore drift, winds and wave erosion. These coastal processes can produce and expose some interesting features.
What are the four main processes of coastal erosion?
There are four main processes of coastal erosion. These are corrasion, abrasion, hydraulic action and attrition. Corrasion is when destructive waves pick up beach material (e.g. pebbles) and hurl them at the base of a cliff.
How are the processes of erosion and mass movement related?
Coastal processes. Processes called erosion, mass movement and weathering break down and remove material from the coast. The material is moved along the coastline by the sea and deposited when there is energy loss. Erosion. Erosion is the wearing away of rock along the coastline. Destructive waves are responsible for erosion on the coastline.
How are waves and attrition related to coastal erosion?
Attrition is when waves cause rocks and pebbles to bump into each other and break up. Corrosion/solution is when certain types of cliff erode as a result of weak acids in the sea. What factors affect the rate of coastal erosion? Coastal erosion is most significant when: a headland sticks out into the sea and waves converge on it (wave refraction).
What are the processes that take place on the coast?
Coastal processes. Processes called erosion, mass movement and weathering break down and remove material from the coast. The material is moved along the coastline by the sea and deposited when there is energy loss.
