How do you think an arch formed? how do you think the dam affects the movement of sediment? write a sentence that explains what shaped wall arch. then name three processes that caused it to collapse. think of two ways gravity glaciers shape landforms.

An arch is formed by process of erosion which can be played by wind, water flow or other elements.

The dam affects the movement of sediment by preventing and controlling the flow of the solids.  

Wall Arch is normally a rock curved shaped as with an opening underneath it.

Erosion, mass wasting and weathering are three process that cause Wall arch collapse.

One way gravity  helps glaciers shape landforms is by attracting the glacier to lower elevations, the glacier then freeze out close lands and soil and rock will stick to it, again gravity then helps the glacier move quickly, because it became heavier with the new agglomerated mass.
