These are called meteorites. Most of these are very small-less than a metre across. They start to burn when they causehappenhittraveldevastatepredictreachprotect the Earth's atmosphere and usually disappear before they causehappenhittraveldevastatepredictreachprotect the ground. A few meteorites are too large to disappear when they burn. They causehappenhittraveldevastatepredictreachprotect at very high speed-about 60000 km/h when they hit the ground-and can cause enormous damage. This happened in Arizona about 50000 years ago and you can still see the crater today. It's called “Meteor Crater”. If another large meteorite hit the Earth today, what would causehappenhittraveldevastatepredictreachprotect ? The explosion would be huge. The meteorite would causehappenhittraveldevastatepredictreachprotect everything around it. If it fell into the sea, it would causehappenhittraveldevastatepredictreachprotect an enormous tsunami. It would be a catastrophe. But the good news is that large meteorites don`t hit the Earth very often. Also, scientists know about the danger, and can causehappenhittraveldevastatepredictreachprotect which meteorites might hit the Earth. It might also be possible to causehappenhittraveldevastatepredictreachprotect the Earth by firing a rocket at a meteorite as it came near to the Earth. This would change its direction and save the world.
