This Dynamic Planet--This map shows the Earth's physiographic features, the current movements of its major tectonic plates, and the locations of its volcanoes, earthquakes, and impact craters. The use of color and shaded relief helps the reader to identify significant features of the land surface and the ocean floor. Over 1,500 volcanoes active during the past 10,000 years are plotted on the map in four age categories. The locations (epicenters) of over 24,000 earthquakes, largely from 1960 through 1990, are plotted in three magnitude categories and in two depth ranges. Illustrations on the back of the map provide detailed explanations for different types of plate boundaries. Tables list past major eruptions, earthquakes, impact craters and plate tectonic milestones by name, date, location and size. The map is intended as a teaching aid for classroom use and as a general reference for research and was revised in 2006. Map scale is 1:30,000,000 and measures 58"x43".
