Geology
-Layering determined by the differences in both chemical composition and physical properties
-On basis of chemical composition: earth has three layers:
core (dense inner sphere)
Radius 3500 km, 95% iron+ 5% nickel
Inner core (solid) we know it’s solid because both p-waves and s-waves pass through it
Outer core (liquid) we know it’s liquid because p-waves pass through it but s-waves cannot
Mantle (less dense) 2900 km made of rock-peridotite
Lower mantle 2400 km (solid)(bottom)
Asthenosphere 400 km (weak/

Temperature: Average energy of molecules or atoms in a material – Kinetic energy of a substance. Heat: Total energy of molecules or atoms in a material,You can have a large amount of heat but low temperatures Can have high temperatures but little heat Latent heat: The amount of heat required to completely change a quantity of water from phase A to phase B with no corresponding change in temperature. “Latent” means “hidden” Residence timesResidence time of a species = mass (or volume) in
