2.  A reverse fault can be compared to a convergent boundary- at both pieces of land collide together  As reverse faults push together, the hanging wall slides up  As convergent boundary is pushed together, the two plates fold up or down creating things like mountains or valleys.

3.  When stress is put on a fault, the hanging wall slides up  This causes earthquakes (or when they’re under water- tsunamis.

4.  Partially solid magma below the surface (in the mantle) churning- known as convection currents  Convection currents move plates by putting stress on them

5.  Plates move about two inches every year unless they can’t move  The longer a plate can’t move, the more stress is built up  When the stress is released there’s move movement… the longer a plate has to wait, the bigger the magnitude of the earthquake.

6.  Damage done of an earthquake depends on the depth of the focus  There are three different types of earthquakes:  shallow= 200 feet  intermediate=200-500 feet  deep= 500 feet  Because Earth’s lithosphere is about 500 feet deep typically- deep focus earthquakes normally happen on land

7.  Earthquakes with shallow focus’ can still cause a lot of damage, even if it’s very low magnitude because it doesn’t need to travel as far to reach the surface  If an earthquake has a deeper focus, less damage will be done because the materials on top of it reduce the power of the waves  The greater the mass of the materials above the focus, the more reduction of power there is
