        Lithosphere
        
        Mohovicic Discontinuity - Moho layer between crust and Mantle
        
        Upper mantle
        
        Largest - nickel and ultramafic rocks with convection cells of movement inside them
        
        Mantle plumes create volcanic hotspots which create volcanic island chains. Shield volcanoes with low silica content.
        
        Crust - oxygen, silicon, aluminum, iron
        
        Hypsometric curve shows proportion of altitude on earths surface
        
        Tectonic plates: large portions of earth crust that move around surface. proposed to move by Wegner and Pangea theory
        
        Oceanic Plates:
        
        Plate movement pushed by gravitational energy from ridge elevation of sinking lithosphere. Measure velocity by comparing to one another, fixed point, or GPS

        Continental Plates:
        
        Wegner supported by glacial striations between continents, fossil distributions, and rocks belts bridging continents
        
        Atmosphere - gathered from volcanic outgassing. Mostly Nitrogen and Oxygen.
        
        Troposphere - all weather
        
        Stratosphere
        
        Mesosphere
        
        Thermosphere
        
        Oceans- after Earth cooled, water vapor condensed to create oceans
        
        Asthenosphere - Soft and able to flow
        
        Lower mantle
        
        Outer Core - liquid and produces magnetic field
        
        Inner core - Solid
        
        Magnetic pole 10 off from rotational and moves
        
        inclination causes compass to tilt up or down w latitude
        
        Paleomagnetism: iron bearing molecules declination and inclination to point to current magnetic north
        
        Positive Anomalies: when seafloor rock shows same polarity as present
        
        Negative Anomalies: when seafloor rock sows different polarity than present
        
        Tracked by magnetometer and stripes of positive and negative show symmetrically from ridges. Width proportional to duration of pole movement.
