A hogback is a homoclinal ridge, formed from a monocline, composed of steeply tilted strata of rock protruding from the surrounding area. The name comes from the ridge resembling the high, knobby spine between the shoulders of a hog. In most cases, the two strata that compose a hogback are different types of sedimentary rock with differing weathering rates. The softer rock erodes more quickly than overlying hard rock.

  • A hogback is a homoclinal ridge, formed from a monocline, composed of steeply tilted strata of rock protruding from the surrounding area. The name comes from the ridge resembling the high, knobby spine between the shoulders of a hog. In most cases, the two strata that compose a hogback are different types of sedimentary rock with differing weathering rates. The softer rock erodes more quickly than overlying hard rock. Over time, the softer rock retreats to a point where the hard and soft rock strata are adjacent. This creates cliffs that steepen as the softer rock continues to erode. Hogbacks are often found as ridges along the "eroded flanks of large, tightly folded anticlines and synclines. " The defining characteristics of a hogback a steep dip slope that is greater than 30° - 40° with a near symmetric slope on each ridge face. A cuesta is a homoclinal ridge with a more gentle dip slope.
  • ホッグバック (Hogback) は組織地形の一。地質構造を反映した差別侵食により形成された山地。侵食地形であり、ケスタと類似しているが、地層の傾斜角が急であり、緩斜面を有さないものを指す。 地殻運動により地層が急傾斜で地表に露出した地形において、軟らかい地層が浸食を受け取り除かれ、侵食の抵抗度の高い地層部が残され山地となったものである。地層の分布・走向に応じてホッグバックの山地も連なった形状を持つ。抵抗度の高い地層部の地層面と山地の傾斜面が一致することはケスタ背面と同等であるが、ケスタより傾斜が大きいことで区分がなされている。
  • 豬背嶺（hogback ridge或hogback）是一種地形，指當侵蝕傾斜排列的岩層後，形成兩邊山坡極斜的山。其形成的環境與單面山類似，都是硬和軟的岩層排列，但地層傾斜度較大，以致軟的岩層被侵蝕後，不僅軟的一面，未被侵蝕而保留的硬岩層的一面坡度也很大。
