This site from Tulane University consists of a lecture by Dr. Stephen Nelson on tectosilicate, oxide and carbonate minerals. The site features a table and description of the minerals in each group, including the nine types of SiO2, the different feldspars, and the calcite group. Optical and physical properties are explained, as well as the environment in which each mineral crystallizes. Full description.

This National Aeronautics and Space Administration (NASA) article discusses the connection between dust storms in Africa, and red tides along the Florida coast. Red tides are blooms of toxic algae that kill fish, birds, and mammals, as well as cause health problems in humans. Storm activity in the Sahara Desert region kicks up topsoil that winds transport into the Gulf of Mexico. These clouds fertilize ... Full description.

This site provides an in-depth and interactive look at the Wilson Cycle in a nine-stage sequence. The Wilson Cycle explains the opening and closing of ocean basins and how certain landforms result; plate tectonics and the rock cycle play a large part in understanding these events. Boundary types are covered, and a series of cross-sections are given to fully explain the cycle. An interactive self-test ... Full description.

This document describes the nature and properties of the sun, its corona, and the solar wind. Students can read how the sun's energy comes from nuclear fusion and how its uneven rotation and churning of its upper layers produces sunspots. The sun's corona is described, and its anomalously high temperature when compared with deeper regions is pointed out. The site also describes how plasma from the ... Full description.

This text discusses how temperature inversion contributes to the powerful winds in Antarctica and, with the help of a diagram, how katabatic winds are created inland and roar toward the coast. Students will learn why it is not uncommon for wind speeds to reach 200 mph in Antarctica. This letter is part of a series written by a glacial geologist working in Antarctica. Full description.
