1
What is the difference between elastic and plastic deformation?
Elastics snaps back into shape but plastic doesn't snap back
Elastic doesn't snap back into shape.
Plastic deformation snaps back into shape.
2
Eruptions of volcanoes occur at hots spots and plate boundaries.
False
True
3
P-waves can pass through liquid and solids.
False
True
4
A fault is a crack where a rock has moved.
True
False
5
Only liquids are come out of a volcano when it erupts.
True
False
6
How is the occurrence of volcanos related to plate tectonics?
By plates due to there being many holes in the crust.
The lava builds up in the holes and then it is released.
Subduction zones are under Earth's light continental plates.
The holes in the plates are perfect for the lava to flow up.
7
How do the scientist know the interior of the Earth?
When a layer changes density the waves changes direction.
P-waves can go through liquids and solids
S-waves can't go through liquid so it shows it is a liquid.
8
Most volcanos are along plate boundaries in the Atlantic.
True
False
9
What is the difference between a focus and a epicenter?
Focus is the point of origin, epicenter is directly above
Focus is on the Earths surface.
Epicenter is in the ground.
10
What kind of gases do volcanos release?
Only carbon dioxide
Only water vapor
Only carbon dioxide and Sulfur dioxide.
Water vapor, carbon dioxide, and sulfur dioxide.
11
When a change in speed causes a wave to change direction it is called refraction.
False
True
12
The Earth's magnetic field has flipped many times.
True
False
13
Buildings are damaged by surface waves because of the ______ rocking.
Front to back
Top to bottom
Back to front
Side to side
14
What does the Richter scale measure?
Amount of damage.
Amount of energy released.
15
Discontinuity is the difference of two layers _____.
Weight
Temperature
Density
Color
16

False
True
17
Who proposed the idea of Pangea?
Nelson Mandela
Isac Newton
Albert Einstein
Alfred Wagner
18
What shows that the Earth's inner core is solid?
S-waves
P-waves
19
A shadow zone has no seismic waves.
False
True
20
What is magma?
Melted rock inside of the Earth.
Melted rock outside a volcano.
Melted dirt outside of the Earth.
21
Earth Quakes are distributed randomly.
True
False
22
How big are Cinder Cone volcanos?
The biggest type of volcanos.
Small and only a few hundred meters tall.
Long and broad.
23
Solids that come out of a volcano is called ______.
Pyroclasts
Pyroclaps
Pyroblast
Pyroexplosions
24
Composite volcanos are the shortest type of volcanos.
True
False
25
Low silica lava and high temperature basalt erupts violently.
Flase
True
26
What causes an earthquake?
Rocks slip in cracks in the Earth's crust.
Thunder hits the ground causing earthquakes.
Lava falls causing the earth to vibrate.
27
What are the three main Plate Tectonic types?
Convergent, divergent, and frictional
Divergent, convergent, and transform
Transform and convergent
28
S-waves are faster than P-waves.
False
True
29
What are some characteristics of earthquakes?
There are 4 stress, compressive, tension, shear, and torsion
Release p-waves, s-waves, and surface waves.
Not randomly distributed.
Occur at different depths depending on the boundary.
30
Hot spots are ________.
Areas of no volcano activity.
Areas of low volcano activity.
Areas of high volcano activity.
31
Mountain ranges from North America, Europe and Africa match together?
True
False
32
Shield volcanos have abundant lava flow.
False
True
33
How did the idea of continental drift lead to the theory of plate tectonics?
He could not support the idea of how continents moved around
With plate tectonics Pangea became accepted.
The theory of plate tectonics supported his idea.
The movement of plates explained how continents could move.
34
What types of animals did he use for matching fossils?
Flying and swimming animals.
Walking animals.
35
What does the Mercalli scale measure?
Amount of damage.
Amount of energy.
36
What are Earth's layers?
Lower mantle
Asthenosphere, Lithosphere
Inner and outer core
Crust, Upper mantel
37
How is seafloor spreading caused?
Magma being pushed up causing the crust to crack and spread.
Water being pushed up causing the crust to crack.
Sand being pushed up causing the crust to crack.
Dirt being pushed up and causing the crust to crack.
38

Fossils and matching mountain ranges
Rocks and asteroid parts.
Trees and water types.
Mountain Ranges and animal skin
39
What pushes the plate tectonics?
Crust push
Ridge push
Sea push
Plate push
40

False
True
