Witrynaof individual particle paths during impact cratering was given by Gault et al. (1968) on the basis of observations of the development and final structures of hypervelocity impact craters in sand in the laboratory. They found that during the cratering flow stage, which they called the excavation stage, particles traveled WitrynaImpact craters are formed when an objects is traveling extremely fast (thousands of miles per hour) through space. When it crashes into a surface at these speeds, it forms a crater regardless of how hard or tough the surface is. The object immediately vaporises (turns from a solid into a gas) and creates enormous shockwaves through the ground ...
