arch
The answer to the question is an aticline.

it depends on the composition of the sandstone
The arch is made up of either sedimentary rock or metamorphic rock. Most likely sedimentary because the layers in the arch are distinct, solid bands of color, whereas a metamorphic rocks have swirly bands of color from the emense pressure the rock went through. Another reason the rock might be sedimentary is because the arch opening would not be as large if the rock was metamorphic rock, which can whithstand more erosion than sedimentary rock.
An arch is typically a result of erosional processes, where softer rock is eroded away, leaving behind harder rock that forms an arch-like structure. It is not typically associated with deposition.

Well you take a rock and arch it... or just buy one at Wal-Mart
An upward fold in a body of rock is called an anticline.
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
An arch in a cliff is formed through the erosion of softer rock layers by natural forces like wind, water, and ice. As these forces wear away the softer rock, a bridge-like structure of harder rock remains, creating the arch shape. Over time, the arch may collapse due to further erosion or structural weaknesses.
