Document Summary

Magnetism: occurs on land too, volcanoes take million years to create, where the rocks pointed where the north pole was proved tectonic plates moved. Convergent boundaries: energy is released when oceanic crust goes under, upper mantle is solid because of earthquakes, volcanoes tell us that subduction occurred, trenches = subduction, subduction to the north. Volcanic terms: active volcano, erupted in last 10,000 years, currently erupting, dormant volcano, is a active volcano that is not erupted but will erupt, extinct volcano, has not had an eruption for at least 10,000 years. Quiescent vs. explosive eruptions: low in silica, flows downhill (responds to gravity) until it crystalizes, term that relates to flow of liquid viscosity, viscosity, resistance to flow, high vis. Easy flow: goes up in the atmosphere (explosive) Mineral classes: sharing, single chains and double chains, 90 degree cleavage, breaks into 90 degrees, iron and magnesium, not good cleavage because made up of single tetrahedra.
