An Etymological Dictionary of Astronomy and Astrophysics
English-French-Persian

A surface feature on a planet or satellite in the form of a line of cliffs. Lobate scarps are formed when planetary or lunar mantle cools down and contracts inside. The loss of volume squeezes portions of the outer crust together. Eventually, the crust breaks and some of it is pushed up, creating long cliffs that look like wrinkles. Lunar scarps are generally tens of kilometers long and less than 100 m high. They have formed during the last billion years.

Lobate "having the form of a → lobe;" → scarp.

Geology: A line of cliffs produced by faulting, erosion, or landslides. → cliff.

From It. scarpa.

Tondé "a steep slope of a mountain," from tond "swift, rapid, brisk; fierce, severe" (Mid.Pers. tund "sharp, violent;" Sogdian tund "violent;" cf. Skt. tod- "to thrust, give a push," tudáti "he thrusts;" L. tundere "to thrust, to hit" (Fr. percer, E. pierce, ultimately from L. pertusus, from p.p. of pertundere "to thrust or bore through;" PIE base *(s)teud- "to thrust, to beat"); cf. dialectal Anzali tin, Laki den, Tâleši teš "steep rock."
