 1.  What does the Richter scale measure vs the Mercalli Scale?

Richer measures magnitude (the amount of energy released from the source)

Mercalli measures intensity (the amount of shaking (or damage) we feel on the surface)

2.  Provide two pieces of evidence to support Alfred Wegner's theory on continental drift.

-pangaea (super continent or that the pieces of the earth fit together)

-fossils (that match fossils on other continents)

-magnetic north is a moving entity (support that continents move)

-glaciation evidence exists on other continents that don't today experience below zero temps (ex. southern Africa)

3.  Name the main types of plate boundaries.

DIVERGENT - where plates are moving away from each other.

CONVERGENT SUBDUCTIVE - where plates are moving towards each other and one plate is forced underneath the other. 

CONVERGENT COLLISION - where two continental plates are moving towards each other & colliding to form “fold mountains.”

TRANSFORM - where plates are moving alongside each other

4.  Pick one plate boundary and explain one thing that happens here because of tectonic activity.

Plate Boundary	Major Landforms	Tectonic Activity
Divergent	Ocean ridges and islands	Small earthquakes and Shield-volcanoes
Convergent (Subductive)	Fold mountains (with volcanoes) and ocean trenches and island arcs if boundary at sea	Big earthquakes and big volcanoes
Convergent (Collision)	Fold mountains and mountain roots	Big earthquakes            (NO volcanos)
Transform	No major landforms are found	Big earthquakes            (NO volcanos)

5.  Define seismic waves.

-The energy released by the earthquake that travel in all directions from the focus point
