GEL 100 Wednesday, August 31, 2011 Learning goals for today: (what students should be able to DO after instruction) Identify and describe major features on the surface of the Earth (including the ocean floor). Identify geographic locations on the surface of Earth with belts of volcanoes, earthquakes, and/or mountains. Describe the combinations of belts of volcanoes, earthquakes, and mountains that exist on Earth. Link surface features and combinations of belts of volcanoes, earthquakes, and mountains with their characteristic kind of plate boundaries.
