Eight large craters run in a long straight line across a geographical region  Although some of the craters contain rocks that have undergone high-pressure shocks characteristic of meteorites slamming into Earth, these shocks could also have been caused by extreme volcanic events  Because of the linearity of the craters, it is very unlikely that some of them were caused by volcanoes and others were caused by meteorites
Thus, since the craters are all different ages, they were probably caused by volcanic events rather than meteorites
No known natural cause would likely account for eight meteorite craters of different ages forming a straight line.
