• Q4
Which describes one process being modeled in the system?
Secondary waves being able to pass through the inner core
Primary/Pressure waves not being able to pass through a liquid layer
Primary waves being able to pass through the air
Secondary/Shear waves not being able to pass through a liquid layer
30s
• Q5
Where in the system are secondary waves not passing through a liquid?
The inner core (center circle/layer)
The crust (outermost layer/circle)
The mantle (third layer/circle)
The outer core (second circle/layer)

• Q6
Examine the model of the Earth's interior pictured. Which describes a process of a concept within the model?
Digging to each layer of the Earth to determine the different layers
Using seismic waves to determine the interior layers of the Earth
Using primary waves to determine the liquid layer
30s
• Q7
Where in the system pictured are seismic waves used to determine the layers of Earth's interior
When each S Wave or P Wave strikes a layer inside Earth's interior a satellite image is sent to a computer
When each S Wave or P Wave strikes a layer inside Earth it either refracts (slows & bends) OR reflects (bounces off)
When each S Wave or P Wave strikes the different layers in our atmosphere a temperature increase is seen
Inside our Earth only the liquid outer core can be determined because these do not allow the P Waves to travel through them
30s
• Q8
P-waves can...
travel through only liquids
travel through liquids and solids
travel through only solids
30s
• Q9
S-waves can travel through
solids only
both solids and liquids
liquids only
30s
• Q10
How many layers of Earth are there?

• Q11
We determine the different layers of Earth's interior by...
digging/drilling to each layer
using seismic waves
30s
• Q12
When seismic waves hit a new layer inside Earth they...
reflect (bounce off) AND refract (go through & bend)
reflect (bounce off)
refract (go through & bend)
transmit (go through)
30s
• Q13
Scientists are able to determine the different layers of Earth's interior because the seismic waves...
S-waves do not pass through the liquid outer core
reflect (bounce off) AND refract (go through & bend) giving them different information at different locations
P-waves do not go through solids
30s
• Q14
The innermost layer of Earth is the
Center
Core
Mantle
Crust

• Q15
The second layer of Earth is called the
Crust
Core
Mantle
Middle
