b. Strong earthquakes

d. None of the above
When seismic waves from earthquakes reach the boundary between the mantle and liquid outer core:
a. all of the body waves get refracted
b. all of the body waves get reflected, but none are refracted
c. all P-waves stop because they are unable to move through the outer core
d. all S-waves vanish because they cannot move through a liquid
Magmas that feed island-arc volcanoes:
a. are a result of decompression melting within Earth’s mantle
b. occur over very wide zones thousands of kilometers in width
c. are located near continental-oceanic boundaries due to magma generation in the Benioff Zone
d. rise along transform faults associated with nearby divergent boundaries
All of the following are features associated with Pangaea except:
a. Panthalassa Ocean
b. Iapetus Ocean
c. Tethys Sea
d. Gondwanaland
If a rock deforms under the influence of a stress, but then returns to its original shape when the stress
is removed, then the deformation behavior is described as:
a. brittle
b. plastic
c. elastic
d. ductile
