Chapter 5. Rigid Earth to Plate Tectonics. Learning Objectives. Know the different types of volcanoes and their associated features. Understand the relationship of the volcanoes to plate tectonics. Know what geographic regions are at risk from volcanoes. Where do volcanoes occur—and why?. Divergent [MOR] boundaries . About 75% of erupted lava is found here. Basaltic magma; low viscosity, therefore it flows easily!. Oceanic crust ranges from about 2 km to 10 km thick. Science ~ chapter 6. volcanoes. Volcanic . Landforms. Section . 3.

Crater. – bowl-shaped formation at the top of a volcano. Caldera. – large crater formed by the collapse of a volcano during a violent eruption. Active Volcano. – . a volcano that has erupted in the past 10,000 years, may be currently erupting, and is expected to erupt again.. Chapter 9 . Section 1. Volcanic Eruptions. Volcanoes – areas of Earth’s surface through which magma and volcanic gases pass. In seconds a volcanic eruption can turn an entire mountain into a cloud of ash and rock. 1/16/13 Volcanic Landforms Notes.
