1) NATIONAL GEOCHEMICAL SURVEY - DATABASE AND DOCUMENTATION, USGS, USGS,
find `geochemical data for the United States based primarily on stream
sediments, analyzed using a consistent set of methods. These data will
compose a complete, national-scale geochemical coverage of the US, and
will enable construction of geochemical maps, refine estimates of
baseline concentrations of chemical elements in the sampled media, and
provide context for a wide variety of studies in the geological and
environmental sciences.`

2) GOOGLE SUGGEST, Google, upon typing a search term, Google offers
keyword suggestions that might help narrow a search. For example,
a 'greenhouse effect' search will yield `greenhouse effect diagram,`
`greenhouse effect causes,` `greenhouse effect solutions` and more. The
limitation of `googling` a search term is that extraneous hits are
encountered, often from sites of questionable quality, but at least with
this resource students
can see how resources and concepts are organized around a particular
search term.

3) SOUTHERN CALIFORNIA LANDSLIDES, USGS, (suggested by Joseph Kerski,
USGS), this site is much more than a description of landslides in
California. Discover links to many valuable resources about landslides
like `Landslide FAQ,` and `Landslide Types and Processes Fact Sheet.`

------------------------------------------------------------------------------------------------------------------------------------------------------------------
4) ALL THINGS CRETACEOUS, SERC, (suggested by John McDaris, SERC), the
Cretaceous collection contains an assortment of digital resources
relevant to the Cretaceous Period (145.5 - 65.5 million years ago).
These resources cover a broad range of topics and include an array of
media types. A variety of images, maps, visualizations, virtual field
trips, databases, technical papers and general information are among the
resource types found here. The Cretaceous collection was created to
allow students and teachers alike to explore the complex relationships
between physical Earth, changing climate and sea level, biota (evolving
and extinct), and implications for modern society that are related to
this amazing period of Earth's history.

5) EXPLORING EARTH, TERC and McDougal Littell, (suggested by Holly
Devaul, DLESE), the site offers investigations of almost every Earth
science topic imaginable. Using imagery and visualizations, it supports
the unit and chapter headings of the Spaulding/Namowitz Earth Science
textbook, offering interactive explorations to complement the topics.
The scope is extensive, covering dynamic Earth processes, atmospheric
science and ocean science. The site was developed through a partnership
between TERC and McDougal Littell and it is an integral part of the
McDougal Littell Earth Science program.

6) GROUNDWATER ANIMATIONS: various sources, find five different
animations or movies for groundwater. Topics include permeability,
groundwater speed, cone of depression, geyser, and hydrologic cycle and
groundwater.

7) GOOD READ: Methane rain feeds Titan's rivers, BBC, `Liquid methane
rain feeds river channels, lakes, streams, and springs on the surface of
Saturn's moon Titan, images from the Huygens probe show.`

8) There are two ways of spreading light --to be the candle or the
mirror that reflects it.
--Edith Wharton

These links are archived at RESOURCES FOR EARTH SCIENCE AND GEOGRAPHY
INSTRUCTION at http://webs.cmich.edu/resgi . The links are organized
around the sequence of topics typically taught in an introductory earth
science or physical geography class. Links are also, available for
environmental science, earth science/geography education, career
opportunities, and more. The sites selected are based on image quality,
ease with which lesson plans can be developed, organization,
authenticity, scope, and format. Please contact me at
