Wilson Alwyn Bentley (1865-1931), famous for his photomicrographs of snow crystals, prepared sets of glass lantern slides of dew, frost and ice crystals. He obtained thousands of photomicrographs of individual ice crystals over the course of his lifetime. Images in this collection are scanned from glass lantern slides. Most snow crystals found in nature will fit into one of these seven main categories: ... Full description.

This applet provides a simulation of the type of precipitation that results from adjusting the temperature (dry bulb and wet bulb) at different altitudes. An updraft in the cloud can be produced in order to see its influence on precipitation. The precipitation types that are simulated include snowflakes/ice crystals, supercooled droplets, raindrops, drizzle, sleet, snow grains, and freezing rain or ... Full description.

This applet enables the user to create snowflakes from different crystals by choosing different temperature zones within a cloud. The crystal grows with each click of the mouse. Moving the mouse to a new temperature zone adds on a new layer. Full description.

In this undergraduate meteorology course, students learn about the Bergeron process of precipitation formation, precipitation types, predicting lake effect precipitation, and estimating the liquid equivalent of snowfall. They may respond to questions as they work through the lessons. A review question is available from the tutorials page. Full description.

This virtual field trip to Stone Mountain Georgia includes both a narrative and photographs of such features as flow banding, tourmaline pods, and several types of xenoliths. Intrusive granite and diabase dikes are shown at both the east quarry and old route 78 locations where products of weathering such as saprolite, kaolinite, halloysite, and gibbsite reside. Photographs of an area of the east quarry ... Full description.

In this activity students will work with ice in order to gain a practical application of math concepts. It will evolve into an inquiry-based study to determine if the dimensions of the ice will make a difference in the way the ice floats in the water. The inquiry lesson may lead to further inquiry-based investigations for extended learning in the classroom or home. Full description.

This atlas provides over 400 full colour photomicrographs of the major ore-forming mineral associations and opaque minerals in non-mineralized rocks. It describes typical examples of each mineral from many classical localities throughout the world. For each association there is a listing of the major (and important minor) primary ore minerals, alteration products and gangue, typical textures, a brief ... Full description.

This site describes the corona of the sun from three different points of view. In the first case, the white-light corona is the sight that is visible during total eclipses of the sun as a pearly white crown surrounding the sun and displays a variety of features including streamers, plumes, and loops. The emission line corona is explained on the basis of the extreme heat of the corona and the X-ray ... Full description.

This site describes the nature of the solar winds and the relationships between its speed and solar features. The effect of the variations in the speed of the solar wind on the magnetosphere of the Earth is also discussed, along with the research results of the Ulysses spacecraft and the Advanced Composition Explorer (ACE) satellite. The site also provides links to solar wind conditions for the last ... Full description.
