- n a streak of light in the sky at night that results when a meteoroid hits the earth's atmosphere and air friction causes the meteoroid to melt or vaporize or explode
- When a meteoreven if it is no bigger than a grain of sandhits the earth's atmosphere, it leaves a long trail of ionized particles 60 miles up.
- Scientists theorize that the blast, caused probably by a meteor or comet fragment that exploded a few miles over the surface of the Earth, was 1000 times as powerful as the bomb .
- Unless the meteor hits in an arid region, its dent is smoothed down quickly (in terms of geological time) by erosion and other natural forces.
