Rocks And Astroids



Millions and Millions of years ago,a meteor hit earth.It was 10 km wide.If the Rock was small it would burn up in the atmosphere.To test it out,you will need...

A hose,5 light balls(to be the small Rock)and a basket ball(to be the meteor that hit earth).

You might want to do this in a swimming pool,but you don't have to.

There are caraters on the moon because,the moon has no atmosphere to burn up the Rocks.
