Volcanoes

For this chart, use the the USGS on-line booklet, "Volcanoes" by Robert Tilling. Read these chapters:

The Nature of Volcanoes
Principal Types of Volcanoes

Fill out the chart. You may not be able to figure out the plate setting or which hazards are assoicated with volcanoes until we talk about it in class.

Type of lava (basalt, andesite or rhyolite)	Size and shape of volcano	Plate setting	Associated hazards (see table below)
Shield volcano:
Volcanic domes:
Cinder Cones:
Composite cones:

For this chart, use the USGS Website "Types of Volcano Hazards". Follow the links in the navigation bar to learn about the different hazards. There is a lot of information here, so you can skim large parts of the Web site. Do pick one case study for each hazard to take a quick look at.

Fill in the chart. Any information you don't find at the Web site we will fill in during class.
