Theory and evidence for Continental drift -Alfred Wegner > the proof he had: Fossils, fit, glaciers, rock types - he just didn’t know how Pangea worked > no mechanism Plate Tectonics - Arthur Holmes came up with thermal Convection ( the mechanism) - New basaltic rock forms along mid ocean ridges and old sea floor is destroyed at deep ocean trenches Henry Hess : Sea Floor Spreading -Mid ocean ridge - linear mountains present in all ocean basics -Age of ocean floor rocks: young rocks ridges and become progressively old with increasing distance from the ridge -plate tectonics theory: the formation movement and destruction of the crust. Location of plate boundaries 3 types of movements: convergent, divergent, and transform Volcanoes The eruptions of molten rock at Earths Surface Distribution of Volcanic Activity: Volcanic dist. Occurs along plate boundaries/// Divergent boundaries mid ocean ridges/// convergent boundaries subduction zones Volcanoes Active: one that has erupted in recorded history Dormant: has erupted for a while – shows little sign of being worn down Extinct: no sign because its not near the magma sources anymore Eruption Exclusivity “ how deadly is it” 1. Composition: ( rock, continental, high (mafic)/ Low (felsic) silica 2. Temperature 3. Dissolved gases Properties of Magma  Viscosity: fluids resistance of flow  Depends on composition ( types of rocks)  Granite composition have higher viscosity magmas ( higher silica content) and produce explosive eruptions -pyroclastic: solids fragments erupted from a composite volcanoes -basaltic lavas have low viscosity and have effusive eruptions 1. Composite Volcanoes - Explosive volcanoes - compound of altenating layers fo lava and pyroclastics > Pyroclastic flows can be triggered -Viscous mudflow of pyroclastic debries and water - May be triggered by rapid snow melt or rain
