How is density related to the layers of the Earth?
without density the layers of the earth wouldn't form
100
Which layer is plastic-like and allows the crust to flow over it?
a. Lithosphere
b. Asthenosphere
c. Mantle
d. Outer Core
b- asthenosphere
100
What rock type is found most readily in the crust?
a. Gold
b. Quartz
c. Gabbro
d. Granite
d. Granite
100
Which wave travels through -the most layers?
p-wave
200
Draw and label a diagram of the Earth's layers. Include the Asthenosphere, Lithosphere, Oceanic Crust, Continental Crust, Inner Core, Outer core
200
Which layer of the Earth is responsible for the Earth’s magnetic field?
a. Crust
b. Mantle
c. Outer Core
d. Inner Core
c. Outer Core/ d.Inner Core
200
Why would the resulting mountains be called “folded mountains”?
Because the layers bend and fold together to form mountains
200
Which wave has - the most straight motions
p-wave
300
If scientists have only managed to drill ⅓ of the way through the Earth’s Crust, how do they know what the center of the Earth is made of?
Scientists use seismic waves to infer what the earth is made of
The s-wave shadow proves that there is a liquid layer (outer core) because s-waves are only able to travel through solid or semi-solid materials
The p-waves show there is a solid inner core because only if the waves refract through a solid layer could they produce the p-wave shadow
300
Which layer is solid and made of iron and nickel?
a. Crust
b. Mantle
c. Outer Core
d. Inner Core
d. Inner Core
300
Why would the resulting mountains be called a “block mountain”?
Because all the layers move together as a solid block.
300
Which wave would travel the slowest
surface wave
400
Name the thickest layer of the Earth.
a. Crust
b. Mantle
c. Outer Core
d. Inner Core
b- Mantle

6. Which layer has strong convection currents which are responsible for the crust’s movement?
a. Crust
b. Mantle
c. Outer Core
d. Inner Core
b. Mantle
400
What could cause some mountains to fault and others to fold
The softness of the materials determines if the crust will fold or fault.
Softer more malleable materials will fold
Harder, more brittle material will fault or break

a. Crust
b. Mantle
