This site consists of a digital total sediment thickness map and database for the world's oceans and marginal seas. The data are derived from previously published maps, ocean drilling results (Ocean Drilling Program and Deep Sea Drilling Project), and seismic reflection profiles (National Geophysical Data Center archives and Geological/Geophysical Atlas of the Pacific). Features include a JPEG image ... Full description.

This lesson focuses upon the scientific phenomenon of El Nino. Learners will also explore the possible link between human-induced global warming, and El Nino as a possible distributor of global warming's extra energy. Links to related sites are included. Full description.

This activity will allow the student to look at real-time satellite, radar, and derived imagery to study the growth and development of thunderstorms. Full description.

This is an introduction to the concept of seafloor spreading proposed by Harry Hess in the early 1960's. This site offers multiple links to further examine this geologic hypothesis. Full description.

This is a group of frequently asked questions and answers about Earth's magnetic field and poles, the magnetic compass, magnetic reversals, and geomagnetic models. Links to maps and illustrations are embedded in the text. Full description.

The magnetic field of the Earth is contained in a region called the magnetosphere. The magnetosphere prevents most of the particles from the sun, carried in solar wind, from hitting the Earth. This site, produced by the University Corporation for Atmospheric Research (UCAR), uses text, scientific illustrations,and remote imagery to explain the occurrence and nature of planetary magnetic fields and ...
