Impact eventAn impact event is a collision between astronomical objects causing measurable effects. Impact events have physical consequences and have been found to regularly occur in planetary systems, though the most frequent involve asteroids, comets or meteoroids and have minimal effect. When large objects impact terrestrial planets such as the Earth, there can be significant physical and biospheric consequences, though atmospheres mitigate many surface impacts through atmospheric entry.
Impact craterAn impact crater is a circular depression in the surface of a solid astronomical object formed by the hypervelocity impact of a smaller object. In contrast to volcanic craters, which result from explosion or internal collapse, impact craters typically have raised rims and floors that are lower in elevation than the surrounding terrain. Lunar impact craters range from microscopic craters on lunar rocks returned by the Apollo program and small, simple, bowl-shaped depressions in the lunar regolith to large, complex, multi-ringed impact basins.

History of FranceThe first written records for the history of France appeared in the Iron Age. What is now France made up the bulk of the region known to the Romans as Gaul. Greek writers noted the presence of three main ethno-linguistic groups in the area: the Gauls, the Aquitani, and the Belgae. The Gauls, the largest and best attested group, were Celtic people speaking what is known as the Gaulish language. Over the course of the first millennium BC the Greeks, Romans and Carthaginians established colonies on the Mediterranean coast and the offshore islands.
