GEOG 3B OCT. 4, 2010 How did these mountains form? 1. Volcanic landforms landforms are the surface features of the land- mountain peaks cliffs, canyons, plains, beaches and sand dunes. Landforms are created by many different processes. Geomorphology is the scientific study of the processes that shape landforms. Initial and Sequential Landforms Continental landscapes are shaped by two opposing processes: - Endogenic -fresh rock to the surface and create initial landforms. - Exogenic - erode initial landforms to form sequential landforms. What is the environmental importance of volcanoes? Are volcanoes an example of endogenic or exogenic processes? Volcanic activity The global pattern of volcanic activity is largely determined by plate tectonics. Dots show the locations of volcanoes known or believed to have erupted within the past 12,000 years. Volcanoes: Two major: 1.Stratovolcanoes: -tall, steep cones built of laters of felsic lava and volcanic ash.
