erosion and deposititon have violently harmed a rock and that is the difference
(sice you are smart enough to keep reading dont write that i promise that is totally not true) thumbs up for warning :)
A sea cave that wears through a cliff is called an arch.
straight from junior cert geography book: A sea arch is a natural archway in a rocky headland. If a cave erodes rights through a headland (or if two caves erode through from either side), an arch may form.
The features sea stack, sea headland, cliff, sea arch, and sea cave all form from continuous wave erosion over a long period.
When a sea arch collapses, the structural support provided by the arch is removed, leading to its collapse. However, the sea cave, which is often carved into the rock by wave action, may remain intact if it is situated in a more stable section of the cliff or if its walls are thick enough to withstand the loss of the arch. The cave can continue to exist as a result of its formation process, where the erosion has created a sheltered space that does not rely on the arch for support. Over time, the cave may continue to be shaped by ongoing erosion and weathering.
A sea arch is formed primarily by erosion. As waves erode the coastline, they create a hole or cave in a headland. Over time, this continual erosion causes the cave to expand from both sides until it forms an arch.
Four land forms would be : sea stack, sea cliff, sea arch, and sea cave.
A sea stack by far. This is because if you imagine a cliff face constantly being eroded away by the waves, the first sign of erosion to appear will be a crack in the rock which will soon open up more and become a cave. Eventually, the waves will keep eroding away the wall until it comes out the other side and becomes an arch. The roof will then collapse due to more erosion and leave a high stack of rock stranded in the ocean. This is the sea stack.
Headland,Sea Cave, Sea Arch, Sea stack,and wave-cut cliff. EXAMPLE WITH SEA ARCH AND SEA STACK: A sea arch is formed when two caves on opposite sides of a headland join. The sea arch collapses when the waves & weathered sediment (rock particles),hit it continuously in which a sea stack is formed. the sea arch is then .eroded and deposited in a new place.
The sea forms a sea cave which goes into a arch then it goes into a stack and finally when the sea eroded for years a stump is formed
a cave is like an arch formed by the erosion of the sea. +++ It may be, but a cave properly is any natural, subterranean cavity of humanly-enterable size, and in scale anything from a small sea-cave (as above) to vast systems of passages and chambers like Mammoth Caves.
A sea arch forms when the rock of a sea cave is eroded through by wave action, leaving behind a natural arch structure that extends out into the water. Over time, the sea arch may eventually collapse, forming a sea stack.
the sea erodes the rock facing out to sea with corrasion etc this form a cave in the rock this gets bigger until it goes all the way through the rock to the other side - this causes an arch after a while the rock above the arch loses support and the rock left over standing in the sea is a stack when this falls over and gets eroded more, it forms a stump
