By the end of today's class, you should be able to do the following:
VOLCANOES
w
List the geotectonic settings in which
volcanoes occur (subduction zones, divergent zones, hotspots).
w
Tell why volcanoes
occur at each of these settings.
w
Tell what makes rock melt in the crust
and mantle settings where volcanoes occur. Describe the process in terms
of changing temperature and pressure, introduction of "impurities" (water and
sediments) into the melt, and draw a graph illustrating these varying
conditions.
w View and
discuss the Raging Planet film, "Volcano!" in light of what you have learned
about volcano shape, eruptive style, and materials erupted.
LATITUDE AND LONGITUDE
w Describe the longitude and latitude coordinate
system for locating points on Earth's surface.
w
Find the approximate latitude and longitude of
