b. Fossil evidence
c. Geologic evidence ( mountain belt comparisions, forexample)
d. All of the above
2. What tectonic event happens that can cause a tsunami?
a. Deflation
b. vertical displacement of the sea floor
c. Slippage along a transorm fault
d. Continental drift
3. The regional "belt" around the rim of the pacific ocean where intense volcanic and earthquake activity has developed from the contract between the oceanic pacific plate and the neighboring continental plates is sometimes called:
a. The "ring of fire"
b. The "hot spot"
c. The "volcanic arc"
d. The ocean trench
4. Plate tectonics is an important theory cannot explain the observed evidence of the drift of continents and the breakup of Pangaea.
True / False
5. An upthrown block of earth crust, standing higher in the landscape, between two normal faults, is called a graben.
True / False
6. The high risk of an earthquake along the San Andreas fault system is partly due to the fact that the fault has been "locked" since the Great San Francisco earthquake of 1906
True / False
7. A transform plate boundary, and a transcurrent fault, exhibit primarily vertical (up and down) displacement between two rock units in motion.
True / False
