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.
2) A bowl-shaped cavity at the mouth of a volcano.
3) The Cup. A small → constellation with faint stars, in the Southern Hemisphere, that lies next to → Hydra, at about 11h 20m right ascension, 15° south declination. Abbreviation: Crt; genitive: Crateris.

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."

  کف ِ لاوک   
kaff-e lâvak

Fr.: sol de cratère   

The lower part of an → impact crater bounded by the rising → crater rim.

crater; → floor.

crater rim
  لبه‌ی ِ لاوک   
labe-ye lâvak

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.

crater; → rim.

cratering
  لاوک زایی، کندال زایی   
lâvakzâyi, kandâlzâyi

Fr.: cratérisation   

The process by which craters form on the surface of Solar System objects.

From → crater + → -ing

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."

craterlet
  لاوک‌چه، کندال‌چه   
lâvakcé, kandâlcé

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.

impact crater
  لاوک ِ برخورد   
lâvak-e barxord

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).

impact; → crater.

lunar crater

lâvak-e šahâbsang, kandâl-e ~, ~ âsmânsang

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.

meteor; → crater.

secondary crater
  لاوک ِ دومان، کندال ِ ~   
lâvak-e dovomân, kandâl-e ~

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.

secondary; → crater.
