2
What layer represents 2/3 of Earth’s total mass?
3
$100 mantle Back
4
What is the plastic layer of the mantle on which pieces of the lithosphere move?
5
$200 Asthenosphere Back
6
What is the only liquid layer of the Earth’s interior?
7
$300 Outer Core Back
8
We know much about the interior of the Earth because we have mapped the movement of these.

11
$500 Andes Mountains South American Plate Andes Mountains Back
12
What is the name of the scientist who first hypothesized the idea of continental drift?
13
$100 Alfred Wegener Back
14
The present day continents were once joined in a large continent known as this.
15
$200 Pangaea Back
16
What is the process by which new oceanic lithosphere forms as magma rises toward the surface and solidifies?
17
$300 sea-floor spreading Back
18
The rate at which the continents move per year can be measured in what units of length?
19
$400 centimeters Back
20

21
$500 iron Back
22
What plate boundary is responsible for creating subduction zones?
23
convergent plate boundary
$100 convergent plate boundary Back
24
What type of plate boundary is the San Andreas fault in California where the plates slide past one another?
25
$200 transform boundary Back

29
$400 Red Sea Back
30
Oceanic lithosphere at mid-ocean ridges slides downhill under the force of gravity because of this:
31
$500 ridge push Back
32
What is the process by which the shape of rock changes because of stress?
33
$100 deformation Back
34
What type of fold is in the rock layers below?
35
