Week 5 - Module 2
Chemical Deposition Landscapes
Movement of iron in groundwater
evaporation causes precipitation
cementation
erosion resistance
Landscape inversion
Global Tectonics
Earth's crust as a number of plates
Types of tectonic plate movement
Rifting (move apart)
Subductions (move together)
Transform (Faults - lateral)
Continental Crust
Upper zone of felsic material
Lower zone of mafic material
Ocean Floor
Entirely composed of basalt lava flows (mafic)
Volcanic Activity
Stratovolcano
Shield Volcano
Basalt flows
tweed volcano
Types of Dating
Classical
Superposition
Fossil Record
Radioactive
More accurate
More tectonics
Rifting
Stretching of continental land mass
Formation of rift valley, volcanic activity
ocean moves into widening gap
basaltic lava forms sea floor
Central ocean expansion
SUMMARY
Climate is dependent on temperature and moisture mainly
