Morphology

meteor + impact

The meaning is directly compositional: a 'meteor' (space object) undergoing an 'impact' (violent collision) yields the event of a meteor colliding with a surface. This is a literal noun–noun combination with no idiomatic shift and mirrors constructions in many languages, so a B1 learner who knows both constituents can infer the MWE meaning.

Etymology

Meteor impact creates a clear picture: a large meteor, a rock from space, crashing with a heavy impact into the ground and making a big hole as dust and fire fly up. So meteor impact means 'the event when a space rock hits the surface of Earth or another planet'.
