Quizplus · Accepted Answer

When the dip of sedimentary rocks is less than 30 degrees, a cuesta forms. A cuesta is a hill or ridge with a gentle slope on one side and a steep slope on the other side. It is formed by differential erosion of tilted layers of rock. The term mesa refers to a flat-topped mountain or hill with steep sides, hogback refers to a steeply sloping ridge, and inselberg refers to an isolated rocky hill or mountain rising abruptly from a plain or relatively flat terrain.
