Google Earth came in handy today for illustrating microclimate. At lower elevations in the Bridger Range near Bozeman, Montana, dense pine forests form on north-facing slopes, whereas grass dominates the south-facing slopes. There is enough of a difference in soil temperature and moisture between the two sides of the ridges to make a significant difference in the microclimate, and hence the vegetation.
Earth science is a very visual topic—I use PowerPoint with lots of images, maps, and graphs—and Google Earth provides an additional tool for classroom and laboratory use.
