Another feature of the Our Dynamic Planet software is the "Map" activity. The CD contains a vast amount of data which is easily accessible by students. Some of the data that the students access are elevation, earthquakes, and volcanoes. Above, students work on the "Map" activity.

Above, students investigate two different types of convergent margins. On the left is a convergent boundary where oceanic lithosphere is being subducted beneath continental lithosphere, giving rise to the volcanic Andes Mountain chain. On the right is a collision zone where two continental lithospheric plates (India and Asia) have collided, forming the Himalayan Mountains. At the bottom of each image is its profile (a cross-sectional view). By viewing the profiles, students discovered that oceanic lithosphere is more dense, and therefore floats lower in the asthenosphere than the continental lithosphere. In the left hand profile, you can actually see the trench which is formed when oceanic lithosphere is subducted beneath continental lithosphere.

Above left, a student has added the volcano database and is in the process of adding the earthquake database to the subduction zones (Aleutian, Kamchatka, and Kuril) in the northern Pacific Ocean. To the right is the northwestern United States with the volcano data plotted.
