Homoclinal ridges are the expression of regional outcrops of moderately dipping strata, typically sedimentary strata, that consist of alternating beds of hard, well-lithified strata, i . e . sandstone and limestone and weak or loosely cemented strata, i . e . shale, mudstone, and marl.

For example, the erosion of homoclines consisting of resistant beds of either limestone, sandstone, or both interbedded with weaker, less resistant beds of either shale, siltstone, marl, or combination of them will produce either cuestas, homoclinal ridges, or hogbacks depending on the angle of dip of the strata.

Because the slope of a homoclinal ridge dips in the same direction as the sedimentary strata underlying it, the dip angle of this bedding ( ? ) can be calculated by v / h = tan ( ? ) where v is equal to the vertical distance and h is equal to the horizontal distance perpendicular to the strike of the beds.
