S and P waves
What type of waves CAN move through liquid
P-waves
What is the most dense: water, oil, alcohol
Water
What is the location called that magma comes out of?
Mid-ocean ridge
What layer of earth is the least dense?
The crust
What kind of waves are slower?
S-waves
What is the force causing more dense objects to sink?
Gravity
Where are the newest pieces of oceanic crust located?
closest to the mid-ocean ridge
What layer(s) of earth is liquid/semi-liquid?
The outer core and the asthenosphere
What kind of waves do more damage?
S-waves
What is the formula for density?
Mass divided by volume
Where are the oldest pieces of oceanic crust located?
The furthest away from the mid-ocean ridge
What is the density of the outer core?
9.9-12.2 g/cm3
Why can't S-waves travel through ALL materials?
If a liquid has a volume of 50ml3 and a mass of 10g, what is the density?
5g/ml3
What are the alternating stripes of color on the sea floor?
The changes is magnetic field over time
What is the depth of the inner core?
5000-6000 km
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.
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
The gravitational pull of materials of different densities
