Fr.: 1, 2) cratère; 3) Coupe
1) A bowl-like depression on the rigid surface of a planet, satellite, or asteroid
usually caused by the high-speed impact of a colliding object.
From Gk. krater "a wide, two-handled bowl for mixing wine with water," from kerannynai "to mix;" PIE base *kere- "to mix, confuse."
Lâvak "a large wooden bowl for kneading dough."
Fr.: sol de cratère
Fr.: bords de cratère
That part an → impact crater that extends above the height of the local surface, usually in a circular or elliptical pattern.
The process by which craters form on the surface of Solar System objects.
From lâvak or kandâl, → crater, + zâyi from zâ- present tense stem of zâdan "to give birth," Mid.Pers. zâtan, Av. zan- "to bear, give birth to a child, be born," infinitive zazâite, zâta- "born," cf. Skt. janati "begets, bears," L. gignere "to beget," PIE base *gen- "to give birth, beget."
Fr.: petit cratère
A small crater often beside a larger one on the surface of the Moon or solid planets.
From → crater + -let diminutive suffix.
Lâvakcé, kandâlcé from lâvak, kandâl, → crater, + -cé diminutive suffix.
Fr.: cratère d'impact
A depression produced by the collision of a meteorite, asteroid, or comet with the surface of a planet or a satellite. Impact craters are the most characteristic surface features of solar system rigid bodies. They range in size up to hundreds or thousands of kilometers (where the impacts create giant basins as on the Moon, Mars, and Mercury).

Fr.: Meteor Crater
A → meteorite impact crater located about 55 km east of Flagstaff, near Winslow in the northern Arizona desert of the United States. Meteor Crater is about 1,200 m in diameter and some 170 m deep. It is thought to have formed between 20,000 to 50,000 years ago, by the impact of a small → asteroid about 25 m in diameter. Same as → Barringer Crater.

Fr.: cratère secondaire
A crater formed by the relatively low-velocity impact of fragments ejected from a large primary crater. Secondary craters tend to cluster in a ring around the primary crater.
Fr.: cratère de Yarrabubba
A crater about 70 km in diameter in Western Australia, considered to be the oldest recognized → meteorite impact structure on Earth. A precise age of 2 229 ± 5 million years is derived from shocked zircon and monazite crystals in the rocks. The age coincides, within uncertainty, with temporal constraint for the youngest Palaeoproterozoic glacial deposits. Numerical impact simulations indicate that a 70 km size crater created by the impact in a continental glacier could release between 8.7 × 1013 to 5.0 × 1015 kg of H2O vapor instantaneously into the atmosphere. These results provide new estimates of impact-produced H2O vapor abundances for models investigating termination of the Paleoproterozoic glaciations, and highlight the possible role of impact cratering in modifying Earth's → climate (Erikson, T.M. et al., 2020, Nature communications, 21 January).
The Yarrabubba structure is located on the Yilgarn Craton in Western Australia (lat. 27° 11'S, long. 118° 50'E), approximately 100 km southeast of the township of Meekatharra; → crater.
