　　People have been finding Moon rocks and Mars rocks at the South Pole．Why the South Pole? It seems that the South Pole (Antarctica) is a really good place to look for them and to find them．

　　Part of the reason for this is that Antarctica is a very large slab of ice sitting on a bed of rock. The ice doesn't stay still．It moves，ever so slowly，from the centre of Antarctica down to the coast (海岸)．

　　When meteorites (陨石) fall on the Antarctic ice，some stay on the surface but most get trapped 　 a few metres down．After all，they do come down with some force and heat!

　　The meteorites get caught up in the ice as they move to the sea and a few million years later most of them reach the coastine．

　　On the way to the sea some of the ice passes round mountain ranges where the meteorites get dislodged．In other words，the ice presses them to the surface．

　　Anywhere else on the earth the meteorites either land in the ocean or cover themselves underground in the soil，never to be seen again．

　　In Antarctica，the little black rocks show up very nicely against the white background.

People who live where there are trees and where there is a completely different climate aren't so lucky!

When people want to know about the weather, they usually go to their radios, TVs, newspapers, or to the Internet. However, you can also find many weather signs among wildlife, because of their highly developed senses. Drops in air pressure produce an effect on small animals in many ways. Mice and deer are good weather indicators. People who spend a lot of time outdoors have observed that, before a storm, field mice come out of their holes and run around. Deer leave high ground and come down from the mountains.

Birds are especially good weather indicators because they also show the effect of a pressure drop in many ways. For example, some birds become irritable(暴躁) and quarrelsome and will fight over a piece of bread. Other birds chirp and sing just before a storm. It seems they know they won’t get another chance for an hour or two. Birds also look for safe places before a storm. You will sometimes see birds settling in trees or gathering together on a wire close to a building. Pre-storm low pressure make the air so thin that birds have difficulty flying.

It is unusual to see many birds flying overhead in the summertime, rather than during the periods in the spring or autumn. Watch for other weather signs if you see this. If they fly in the wrong direction, they may be flying ahead of a storm.

By paying closer attention to some important signs in nature, we can become better prepared for any kind of weather.
