you may not know this but sea cliffs are made by rock and many other minerals
Cliffs that are eroded by upward drafts of wind and ocean waves
Steep cliffs above the river.
It is difficult to determine an exact number of sea cliffs in Ireland, as the coastline is rugged and there are many cliffs of varying sizes along the coast. Some of the most famous sea cliffs in Ireland include the Cliffs of Moher, Slieve League, and Loop Head.
The largest sea cliffs in the world are located at Kalaupapa National Historic Park on Molokai, Hawaii. Molokai is one of the eight main islands in the Hawaiian archipelago and is situated geographically northwest to the island of Maui and southeast yo the island of Oahu, home of the states capital Honolulu.
usually erosion happens when a weather condition is in place e.g wind, heavy rain, floods. or if a cliff is partially in the sea with time the sea can erode away at it. hope this helps (by the way this is just a brief rundown of erosion if you want more detail ill be happy to help) :) x
Low hills, with steep sea cliffs.

Sea cliffs are primarily formed by erosion, typically from the action of waves and weathering processes wearing away at the coastal rock over time. Deposition can also play a role in the formation of sea cliffs when sediments accumulate at the base of the cliff.
Three types of landforms created by wave erosion are sea cliffs, sea caves, and sea stacks. Sea cliffs are steep rock faces formed by the erosion of coastal areas by waves. Sea caves are cavities within cliffs or rocks that have been eroded by wave action. Sea stacks are isolated pillars of rock that once formed part of a headland or cliff.
Relict cliffs are geological features that were formed by erosion and are now no longer actively being eroded. They often represent the remnants of ancient landscapes that have undergone changes over time, such as changes in sea levels or tectonic activity. Relict cliffs can provide valuable information about past environments and help geologists understand the geological history of a region.
