Meteors V.S. Crater

Meteor is a bright star which always fly into the night sky quickly. It might be the small planet or the gravel of comet. While the meteor get into the Earth's aerosphere, it will get burned and last about one or two seconds. That is the right time that you see the meteor with a shining tail in the night sky.

The crater was formed when the small planet hit the Earth. One of the famous tourist attractions - Arizona, is located in the southwest region of the United States, is a crater. It is said that it was formed when the crater fall into Arizona.

Here is the experiment on making artificial crater. First, pour flour into a washbasin. Second, drop a small plastic ball into the washbasin, and it will cause a hole. Third, take out the small ball and you will find the hole which was formed when the plastic ball fall from the high way. The hole is just the crater.
