Definitions The Structure of the Earth
Part of the Earth that is water.
Hydrosphere
Break in rock.
Fracture
Hard, rigid, the earth's outermost thinnest layer. Only a few miles (5km) thick under the oceans and averaging 20 miles (20 km) thick under continents.
Crust
An extremely hot, soild sphere of mostly iron and nickel at the earth's center. 3200 to 3960 miles below the surface and about 750 miles in diameter.
Inner core
If the mass of an object is 35 grams, and it takes up 7 cm3 of space, calculate the density. Show work, and the units or your team will not get the point.
Solution: D = 35g/7 cm3
D = 5 g/cm3
The line on the map runs from the north to the South Pole.
Instruments that detect earthquakes.
Seismograph
Divided into two sub regions, upper and lower, this dense layer made of hot semi rock is located directly below the crust and is about 1800 miles thick.
Mantle
Is the amount of space that an object takes up.
Volume
What is the density of a rock with a mass of 35 grams and a volume of 7.0 cubic centimeters? Show work, and the units or your team will not get the point.
35 g (mass)/ 7.0 (cm)^3 (volume)
5.0 g/cm3
Measurements in degrees east or west of the prime meridian.
Longitude
Earthquakes waves.
Seismic waves
Made up of the crust and a tiny bit of the mantle, this layer is divided into several constantly (very slowly) moving plates of solid rock that hold the continents and oceans.
Lithosphere
You would typically measure an irregularly shaped solid in what instrument? And what is its unit of measurement?
Graduated cylinder; L or ml
Mass = 140.25g Volume = 33 ml Density =

140.25 g (mass)/33 ml (Volume)
4.25 g/ml
difference in elevation between one contour line and the next
Contour interval
Scales that measure the intensity (energy) of an earthquake.
Ritcher Scale
The plates of the lithosphere move or float on this hot, malleable semi-liquid zone in the upper mantle, directly below the lithosphere.
Asthenosphere
What is the density formula?
Density = Mass/Volume
What is the density of vegetable oil with a mass of 25g and volume of 25 ml?
Show work, and the units or your team will not get the point.
25g (mass)/ 25ml (volume)
= 1 g/ml
Imaginary line on a map or globe that circles earth east to west parallel to the equator.
Parallels
Movement of magma inside the earth.
Magmatism
Outer core
What are the units of measure for a solid? What are the units of measurement for a liquid?
Solid = g/cm3
Liquid = g/mL
What are the formulas for both mass and volume?
Formula for mass: M = D x v
Formula for volume: V = M/D
