Making direct contact with people - the Internet opens many possibilities for getting in direct contact with earth scientists and other students or teachers. From these pages you can access selected USENET newsgroups on earth and planetary science and add your own comments or just follow the discussions on a wide range of topics. You can also join LISTSERV mailing lists. Many other opportunities have been classified using the Dewey system, so that you can find links to experts and online projects in the various fields of astronomy and earth science. If it´s to do with communicating with others, then go here.
