Lecture notes including information on Nekton

1. superposition The principle that any given rock layer is probably older than those above it and younger than those below it 2. continental crust Extends from surface of Earth down to 20-30 miles. Continental crust (granite) is less dense then ocean crust (basalt). 3. oceanic crust Extends down from the surface of the Earth to 7 miles. Crust is layered and very uniform. Com- posed of basalt. 4. mantle Contains most of Earth's mass. Composed of iron, magnesium, aluminum, and silicon-o...
