What type of waves CAN move through liquid 

P-waves 

100

What is the most dense: water, oil, alcohol 

Water

100

What is the location called that magma comes out of?

Mid-ocean ridge

100

What layer of earth is the least dense?

The crust 

200

What kind of waves are slower?

S-waves 

200

What is the force causing more dense objects to sink?

Gravity 

200

Where are the newest pieces of oceanic crust located?

closest to the mid-ocean ridge 

200

What layer(s) of earth is liquid/semi-liquid?

The outer core and the asthenosphere 

300

What kind of waves do more damage? 

S-waves

300

What is the formula for density?

Mass divided by volume 

300

Where are the oldest pieces of oceanic crust located?

The furthest away from the mid-ocean ridge 

300

What is the density of the outer core? 

9.9-12.2 g/cm3

400

Why can't S-waves travel through ALL materials?

Because they are shearing waves (move side to side) and cannot push through liquids 
400

If a liquid has a volume of 50ml3 and a mass of 10g, what is the density?

5g/ml3

400

What are the alternating stripes of color on the sea floor?

The changes is magnetic field over time 

400

What is the depth of the inner core?

5000-6000 km

500

What is the relationship between the distance from the epicenter and the seismogram?

The further the seismogram is away from the epicenter, the longer it will take to reach it. Also, the less severe the earthquake will be the further away the epicenter. 

500

A piece of metal has a density of 7.8 g/cm³. If its mass is 234 grams, what is its volume?

30cm3

Explain how the model we created represented sea-floor spreading 

answers may vary

What caused the interior of earth to separate into layers 

The gravitational pull of materials of different densities
