50. Sea-Floor spreading creates new lithosphere. Label
each of the following as True or False:
a. (T or F) Explains continental movement
True
b. (T or F) Rocks closer to ridges are younger than
rocks farther away.
True
c. (T or F) Continental rock is younger than oceanic
rock.
False
51. What are mid-ocean ridges?
Areas of sea floor spreading
Where do they occur?
Plate boundaries
Why didn’t Wegener use them as evidence for
continental drift?
Mid-ocean ridges were not
discovered until WWII
after his death.
52. Explain how plate tectonics works at mid-oceanic
ridges: First magma heats up in the asthenosphere and
rises, then it
Erupts along a fissure
Then
Pushes the plate apart and cools

87. If thick ice sheets covered large parts of Earth’s continents again, how
would you expect the lithosphere to respond to the added weight of the
continental ice sheets? Explain your answer.
• Isostasy- The balance between the pull of
gravity on the lithosphere and the push of the
asthenosphere.
• If the mass of the crust increases, it sinks.
• New mountains, glaciers, sediment
deposition
• If the mass of the crust decreases, it rises.
• Erosion of mountains, melting of glaciers.
• DO NOT just copy these notes think about what adding
weight to something does. Remember the Ship analogy (An
unloaded ship will float higher in the water than a fully
loaded ship.
88. How would the isostatic adjustment that results from the melting of glaciers
differ from the isostatic adjustment that may occur when a large river empties into
the ocean? Support your answer.
• Isostasy- The balance between the pull of
gravity on the lithosphere and the push of
