Geosci 10 Tuesday, February 9th, 1999 Announcements: Test Thursday -- 100 points; fill in the blanks, short answers; know vocabulary, convective rates, Pangea dates, detail, geography, etc.; Class was all review Lecture notes: I. Review of notes A. Three styles of heat transfer 1. Conduction -- hot pot of water is taken away from its original setting and placed elsewhere, the air around the new area is then heated up because of the hot pot of water; process is very slow 2. Advection -- take a large piece of hot material or rock and set it away from its original environment; it is like taking hot rock and placing it near a fault zone 3. Convection -- spontaneous movement of material driven by density which is controlled by temperature; a full cycle of movement (convective system) B. Continental rifting -- related to sea floor spreading; occurs in three places around the world (Western US, Siberia, and the African Rift); material is pushed up from below the lithosphere which which creates a dome shape which then cracks the lithosphere and pushes the rock apart C. Differences between asthenosphere and lithosphere 1. Asthenosphere -- equivalent to the mantle of the earth; like tar, very oozy and sticky; it is soft, slowly mobile: no earthquakes; can provide magma for volcanoes 2. Lithosphere -- equivalent to the crust of the earth; very hard outer
