Heat
The closer you get to Earth's center, the temperature __________
Increases
Mechanical layers are defined based on _________
The texture of the rock, or the physical state of the rock
Compositional layers are defined based on __________
The composition of the rocks, or what elements the rocks are made of
The cause of seismic waves
Earthquakes
Hey now, you're an all-star, get your game on, go play
Hey now, you're a rock star, get the show on, get paid
And all that glitters is gold
Only shooting stars break the mold
Type of heat produced by molten rock moving against itself
Friction heat
The mechanical layer of Earth that is made of cold, solid rock
Lithosphere
The compositional layer of Earth that we can directly observe
Crust
Type of wave that arrives at seismometers first
P waves
We're no strangers to love
You know the rules and so do I
A full commitment's what I'm thinking of
You wouldn't get this from any other guy
Type of heat generated by radioactive materials such as Uranium, Potassium, and Thorium.
Radiogenic Heat
The mechanical layer of Earth that is liquid
Outer core
The compositional layer of Earth that has convection currents which push the tectonic plates directly above it
Mantle
Type of wave that cannot pass through liquids
S waves
There's a hundred and four days of summer vacation
Then school comes along just to end it
So the annual problem for our generation
Is finding a good way to spend it
Like maybe...
Building a rocket
Or fighting a mummy
Or climbing up the Eiffel Tower
Discovering something that doesn't exist
Type of heat produced by the energy from the accretion of space dust/rocks from the formation of the Earth
Primordial Heat
The mechanical layer of Earth that is solid, yet still flows over a long period of time
Mesosphere or Asthenosphere
The compositional layer of Earth that is made of heavy elements such as Iron and Nickel
Core
Type of wave that is compressional, and can pass through both solids and liquids
Just a small town girl
Livin' in a lonely world
She took the midnight train goin' anywhere
Just a city boy
Born and raised in South Detroit
He took the midnight train goin' anywhere
What evidence is there of heat in the interior of Earth?
Plate tectonics, convection currents, geothermal heat, magnetic field
The cause of the Inner Core being solid
Pressure
Elements that make up most of the rocks in the Crust
Silicon and Oxygen (Silicates)
Evidence for a liquid outer core
S wave shadow
Stars
In your multitudes
Scarce to be counted
Filling the darkness
With order and light
