Weathering and erosion.
Sandstone formations are brought to the surface by the removal of overlying rock structures by erosion, or by uplift from not-fully-understood tectonic processes. As the sandstone nears the surface, cracks appear in the rock formation from pressure release as the weight of overlying rock is removed by erosion. In arid regions, freeze-thaw cycles will enlarge the existing cracks, and the wind will ablate the sandstone into narrow wall shaped structures. Eventually, a hole may appear through these wall shaped structures, and enlarge to form arches. In temperate areas, water plays the biggest role in arch formation, creation occurring where two sandstone overhangs form back-to-back, and their eroded undercuts finally merge into an opening that eventually forms an arch.
As part of the mainland gets eroded by weathering and sea waves, a patch of land forms. With further erosion, the patch of land is joined with the mainland by only a small arch.
Rock arches are changed by weathering and erosion from ice, wind, water, and gravity.
No.
no a waterfall is caused by physical weathering
when wethering and erosion happens, parts of the land are swept away by things like water or wind. that carries them away and deposits them some where else. that leaves a new formation such as the arches in arches national park. they were formed the the Colorado river and it left the arch shapes in its place.

It is a vault or vaulted roof. It is formed by a series of vaults/vaulted arches.
it is said that you can lick the roof of its arches because of its texture.

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.

In deserts, arches and mushroom rocks are formed when the sand in sand storms blows it and other materials against the rock which eventually erodes the rock into interesting shapes such as arches. ~Tom1819
