This document provides information about volcanoes, including what they are, the different types, how they form and erupt, examples of specific volcanoes, and the impacts of eruptions. It discusses how volcanoes are categorized as active, dormant or extinct based on recent eruption activity. Shield volcanoes slowly release lava to form broad slopes, while cinder cones explosively eject ash and rock to form steep cones. Composite cones can erupt both explosively and effusively. Mount St. Helens last erupted in 1980.

INTRODUCTION
This module examines plate tectonics. Topics include continental drift, tectonic landforms, plate boundaries, faults and hotspots. While these topics may appear to be disparate, you will learn how they are inherently related. The module starts with four opening topics, or vignettes, which are found in the accompanying Google Earth file. These vignettes introduce basic concepts of the internal structure of the Earth. Some of the vignettes have animations, videos, or short articles that will provide another perspective or visual explanation for the topic at hand. After reading the vignette and associated links, answer the following questions. Please note that some links might take a while to download based on your Internet speed.
