4
The youngest part of the ocean floor is found...
where ocean sediments are thickest
near ocean ridges
along deep sea trenches
where earth's magnetic field changes polarity
5
Subduction results in the formation of

6
At an oceanic-oceanic convergent boundary...
old crust is deformed or fractured
old crust is recycled by subduction
new crust is created
plates slide past one another
7
The downward part of a convection current causes a sinking force that...
creates a divergent boundary
moves plates apart from one another
causes plates to subduct into the mantle
lifts and splits the lithosphere
8
Which of the following landforms results from divergence of continental crust?
a long fault
a Rift Valley

9
Compared to ocean crust near ocean ridges, crust near deep-sea trenches is...
younger
magnetically reversed
older
the same age
10
Why is a transform boundary classified as “conservative”?
There is little destruction of material along this boundary
The frequency of earthquakes along this boundary is small

Which of the following features forms when two oceanic plates converge?
magnetic reversal patterns
rift valleys
subduction zones
divergent boundaries
16
Pangaea was an ancient supercontinent made up of
the United States, Greenland, and Europe
all of Earth’s continents
South Africa, India, Australia, and South America
Antarctica, India, and South America.
17
Coal beds in Antartica indicated to Wegener that this continent was...
always cold
once located closer to the equator
once beneath the ocean
inhabited by penguins
18
The driving forces of tectonic plates are related to convection currents in Earth's...
inner core
mantle
outer core
crust
19

much different from magnetic patters found in rocks on land
at right angles to the ocean ridge
a mirror image of that of the other side
younger than on the other side
20
Tectonic plates interact at places called plate
subductions
boundaries
reversals
regions
