There are four main ways in which the coast can be eroded by the sea:
Hydraulic action:lots of sea water crashes against the land, causing air and water to become trapped and compressed in surface cracks. When the sea retreats the air expands, weakening the cracks in the rock and causing pieces of the rock to break off.
Corrasion: caused by bits of rock hitting the cliffs and other parts of the land, causing more bits of rock to break off.
Attrition: rock fragments grind each other down into smaller and smoother pebbles and eventually into sand which is then deposited on the beaches.
Corrosion: involves the chemical action of sea on rock, often happens with limestone beaches, when the limestone dissolves in the sea water although the salt can affect some other stones as well.

Do all coast erode at the same rate?
no, many coast lines are made of different rocks (some harder and some softer) and have different chemical compounds in the sea water.
How are sea stacks formed and sea archs?
By erosion. Sea caves erode to become sea arches which erode to form sea stacks.
Why doesn't a river erode to the center of the earth?
It only needs to erode to the highest point of a body of water, such as sea level.
What happens to the stump over time?
The stump will decay/erode and collapse into the sea.
How is a sea arch formed?
A sea arch is formed by the erosive action of waves crashing against a headland or cliff, gradually wearing away the rock through processes like hydraulic action and abrasion. Over time, a small hole is formed, which enlarges and eventually erodes through the headland, creating a natural arch. Continued erosion may cause the arch to collapse, leading to the formation of a sea stack.
How does the sea erode?
The sea erodes its coasts, mostly by the violent process of waves action, in conjunction with tides and ocean currents.
How are Sea Stacks and sea arches formed?
Sea stacks are formed when a sea arch collapses and sea arches are formed when waves (pound) erode or ware away a whole in the headland.
What will happen to the stump over time?
The stump will decay/erode and collapse into the sea.
How are barrier island communities vulnerable?
wind and wave conditions and rising sea level erode the islands
What is the capital of the Erode district?
Erode is the Capital of the Erode District.
What is an antonym for erode?
A synonym for erode is build or construct.
How can the word erode be used in a sentence?
