D. were grouped differently
21
D. Were grouped differently
22
What is the outermost layer of
Earth?
23
crust
24
What is an earthquake wave that
makes the ground roll and sway?
25
Surface wave
26
What is the layer directly above the
outer core?
27
mantle
28
The large, stiff plates of the
lithosphere float on the
asthenosphere because of…
29
The asthenosphere’s plasticity
30
How often does Earth’s crust
move?
31
All the time.
32
What is a point in Earth’s crust
where an earthquake starts?
33
focus
34
What is a push/pull or back and
forth wave caused by earthquakes?
35
P wave
36
The temperature inside the core is
over 5500 degrees Celsius, but it
remains solid because…
37
Of immense pressure
38

happen to San Francisco because
of the movement of Earth’s plates?
39
It will be off the coast of Alaska.

along it?
43
Convergent boundary
44

is always changing.
45
