The layers are parallel to each other because they were formed by sediments falling to the bottom of the seas in horizontal layers (see above), but when the continents crashed together at a convergent boundary, the rocks and sediment under the sea were squished and folded.
When sediments settle out of water, they form horizontal layers.
When sediments settle out of water, what do they form?
