Word Origin and History for cratering
1610s, from Latin crater, from Greek krater "bowl for mixing wine with water," from kera- "to mix," from PIE root *kere- "to mix, confuse; cook" (see rare (adj.2)). Used in Latin for bowl-shaped mouth of a volcano. Applied to features of the Moon since 1860. As a verb, from 1830 in poetry, 1872 in science. Related: Cratered; cratering.
- A circular depression or pit in the surface of a tissue or body part.
- A bowl-shaped depression at the top of a volcano or at the mouth of a geyser. Volcanic craters can form because of magma explosions in which a large amount of lava is thrown out from a volcano, leaving a hole, or because the roof of rock over an underground magma pool collapses after the magma has flowed away.
- A shallow, bowl-shaped depression in a surface, formed by an explosion or by the impact of a body, such as a meteorite.
