He was an ancient Greek mathematician, astronomer, physicist, engineer, and inventor. He supposedly measured the density of the king's crown to determine it was not pure gold.
Who was Archimedes?

Name the three layers of the earth
The crust, mantle, and core
100
What are the two types of seismic waves
P & S waves
100
Free
Free point

What is density
Density is the measure of the amount of mass per unit of volume
200
Where does convection take place
Asthenosphere
200
What are the two types of crust
Oceanic and Continental
200
What zone do P & S waves not pass through
The shadow zone, the core stops the P & S waves
200
Free
Free point
200
What is 300 g of water frozen
300 cm3
300
What is the outer zone of the earth
The lithosphere
300
What is the layer with the most mass
The mantle
300
What can't S waves travel through
They can't travel through liquids, they can't travel through the outer core
300
What are Observations and Inferences
Observation: gaining information through your senses Inferences: a logical deduction based on something you know or observe
300
What are the density formulas
M \ V = D D x V = M M / D = V
400
How does convection work
Convection is the heat from the outer core rising and cooling in the mantle then falling and heating then so on and so on, this moves the crust
400
The densest layer
The core of the earth
400
What is the Moho
The Moho is the boundary between the crust and mantle, rocks become much more dense past this boundary
400
How are Observations and Inferences important to science
They help us learn more about the world
400
How can density increase and decrease
The higher the mass the increased density The lower the mass the decreased density
500
Where are all the zones
Lithosphere is in the crust and mantle Asthenosphere is in the upper core Outer and Inner core are in the Core
500
What is primarily made up of nickel and iron
The core
500
What is refraction
Due to the density of rocks and the speed of the waves they make curved waves, this called refraction
500
How are observations and inferences alike and different
Alike: they both help us learn more about the world Differences: observations are directly based off the senses, inferences are based off observations and logical deductions
500
A pencil has a density of 1.5 g/cm3, will it sink or float
Sink
