How are anticlines formed?

An anticline is a structural trap formed by the folding of rock strata into an arch-like shape. The rock layers in an anticlinal trap were originally laid down horizontally and then earth movement caused it to fold into an arch-like shape called an anticline. Are anticlines formed by compression? Compression pushes rocks together. Anticlines and
