Dorsum (astrogeology)

Dorsa in the Mare Serenitatis . These flat, elongated wrinkled ridges in the Maria des Mondes are also called sea ridges after their occurrence.

Dorsum (plural dorsa , from Latin dorsum = back) is a term used in astrogeology for surface structures of planets , satellites or asteroids similar to ridge-like surfaces . It is a purely morphological name, so it says nothing about its origin. Well-known examples are Eumenides Dorsum and Schiaparelli Dorsum on the planet Mars and the Dorsum Termier on the Earth's moon.
