Here you will find resources to help educators and their students use several present-day distributions of minerals, rock formations and fossils to help figure out the distribution of continents; construct a map showing the position of continents 250 million years ago by reversing the present direction of plate motion; recognize a convergence of presently widely scattered minerals, rock formation and fossils when all the continents where part of Pangea; compare present average community motions with that of the past 250 million years by calculating the average yearly rate of motion over the last 250 million years; describe the context in which the hypothesis of continental drift was proposed and why it was subjected to criticism; show that your community has moved through different ecological regions over time.

Here you will find resources to help educators and their students use maps to examine the distribution of earthquakes and volcanoes to the location of plate boundaries; explain the location, nature and cause of volcanic arcs in terms of plate tectonics; explain the location, nature and cause of hot spots; explain how plate-tectonic processes have caused continents to grow through geologic time; explain how plate-tectonic processes produce landforms; explain how plate tectonics can affect the interior of a continent.
