Sea caves are caused by hydraulic action, abrasion, attrition and solution eroding into lines of weakness on the headland. These same processes continue to widen and deepen the cave until it cuts through the rock forming an arch.
No, they are natural sea-caves and arches.
The sea first forms sea caves then sea arches then sea stacks and finally it forms sea stumps which will eventually disappear.
Wave-cut cliffs, headlands, sea stacks, sea arches, sea caves, beaches, sandbars, and spits.
A sea arch is an opening that was made naturally by the ocean by the sea water eroding the rock. Sea arches can also be formed by wind, or by the land. Or they can also be combination of all three. A sea arch is an arch that is made from an eroded cliff face. The water makes the sea arch after many years.
By erosion. Sea caves erode to become sea arches which erode to form sea stacks.
Headlands, bays, sea caves, and sea stacks are four features formed by wave erosion along a coast. Headlands are rocky structures jutting out into the sea, while bays are curved inlets where the land recedes. Sea caves are hollowed-out spaces in coastal cliffs, and sea stacks are isolated rock pillars left behind from eroded cliffs.

It is simply sea caves, canyons, evened out shorelines, and abrision+collision=plucking and sea caves. That's the way that geographers and scientists think of it because this is just the easiest explanation of this term. Your welcome
Water. Specifically the wave action beating on the cliff.
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.
They are both caves
