what defences do the coastline s use against coastal erosion
No, coastlines can erode at different rates depending on factors such as the type of coastline (rocky vs sandy), wave energy, climate, and human activities. Some coastlines may erode faster due to stronger wave action or storm surges, while others may erode more slowly due to protective measures or natural features.
Waves can build coastlines by depositing sediment and creating features like beaches and sandbars. However, waves can also erode coastlines by wearing away rocks and cliffs through processes like abrasion and hydraulic action. The balance between these two processes determines whether a coastline is being built up or worn down.
Coastlines can be formed by - waves that erode the sand.
The principal mechanism by which waves erode coastlines is through wave action, which involves the force of water crashing against the shore. This energy dislodges and transports sediment and rocks, a process known as hydraulic action. Additionally, waves can create turbulence that further weakens coastal materials, leading to erosion. Over time, this continuous process shapes the coastline, creating features like cliffs, caves, and beaches.
They wear away rock at the base of rocky shorelines.
All coastlines in existence constantly erode as a product of the tides slowly destroying them by fractional increments.

There are a number of ways that rain can have an affect on rocks. Usually rain will erode rock surfaces.
the brakes affect the speed
The speed of water affects erosion by increasing the force exerted on the surface it is flowing over. Higher speed water carries more sediment and particles, which can increase erosion rates by scouring and removing material more quickly. Conversely, slower-moving water may also erode material but at a slower rate due to decreased force and sediment transport capacity.
Speed affects the frequency and pressure affects the wavelength.

Running water can erode the land by carrying sediment and wearing down rocks through abrasion. Groundwater can dissolve minerals in rocks, weakening the material and causing erosion. Waves can erode coastlines by breaking down rocks and carrying away sediment. Glaciers can erode the land by plucking and abrasion as they move, and deposit sediments when they melt.
Global warming has caused the permafrost to melt letting coastlines and inlets to recede into the land slowly flooding villages.
