  2. diverging plate boundaries. Plate Tectonics Volcanoes form along plateboundaries. http://www.geo.lsa.umich.edu/~crlb/COURSES/117/Lec19/div.jpeg converging plate boundaries. http://www2.nature.nps.gov/geology/usgsnps/pltec/contvsocn288x157.gif and hotspots. http://www.geologyrocks.co.uk/geopics/ptmap.gif Volcanoes form along three different types of boundaries. They are: http://www.tulane.edu/~sanelson/images/hotspot.gif

  3. Magma Properties: Viscosity—greater the viscosity, the slower it flows. • Physical, difference • Density • Melting point • Hardness • Magnetic High viscosity… molasses Low viscosity… water • Chemical, difference • Ability to burn • React • Combine http://www.ci.fort-collins.co.us/water/water-images/water-hands.jpg http://www.svgintermol.com/images/molasses_drip_lge.gif
