Most meteorites start to burn when they reach the Earth’s atmosphere. They get much smaller or disappear.
This crater is from a meteorite that hit the earth. Until 1903, scientists thought it was the crater of an old volcano

A BIG HIT?
Every year, thousands of rocks from space 1______to Earth. These are called meteorites. Most of these are very small – less than a metre across. They start to burn when they 2______ the Earth’s atmosphere and usually disappear before they 3______ the ground. (see picture 1). A few meteorites are too large to disappear when they burn. They 4_______at very high speed – about 60,000 km/h when they hit the ground – and can cause enormous damage. This happened in Arizona about 50,000 years ago and you can still see the crater today. It’s called “Meteor Crater”. (See picture 2.) If another large meteorite hit the Earth today, what would 5________? The explosion would be huge. The meteorite would 6__________everything around it. If it fell into the sea, it would 7________ 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 8_________ which meteorites might hit the Earth . It might also be possible to 9__________ 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.
