The Moho - boundary between Crust and Mantle
The Mohorovicic Discontinuity marks the lower limit of Earth's crust.
The MantleThe Mantle
2/3 of the Earth’s Mass, 70% of Volume
Upper Mantle has Lithosphere (solid) and Asthenosphere pressure keeps it solid (plasticity)

Seismic Waves• Waves Created by an
Earthquake or Explosion
• Primary (P) Waves move through liquids, solids, Gas
• Secondary (S) Waves move through only solids
• Waves bend with changes in density
Shadow Zones
• Non-uniform rigidity in material
• No S or P waves can get through
• OR P can get through but not S
Isn’t the North Pole where Santa Lives?
The Earth’s Magnetosphere
-Created from movement of the liquid, which creates a electrical current in the outer core (iron and nickel) -Dipole is created (like a magnet)-Magnetic North and Magnetic South are different from Geographic North and Geographic South
Magnetowha?
GravityMass- the amount of matter in an object, independent of gravity.
Weight- measure of the strength of the pull of gravity on an object.
Law of Gravitation- states that the force of attraction between any two objects depends upon their masses and the distance between them.
Is your weight the same all over Earth? Think of
the shape and your distance from Earth at
different locations.
