A volcanic explosion, a rising mass of salt, and a large meteor impact were all explanations put forward to explain how meteor crater formed.
A crater is a bowl-shaped depression or hollow area formed by a meteorite impact, volcanic activity, or an explosion. Impact craters form when objects such as asteroids and meteorites collide with larger solid surfaces such as planets and moons. Craters form when solids collide at super-velocity, no matter how hard they are.
Instantly evaporates, creating a huge shockwave on the ground that melts and recrystallizes rock. All that's left is a large circular hole in the ground and some very crumbling rocks. Volcanic activity often creates craters. Some volcanic craters are deep and have steep sides while others are wide and flat.
