100
What is the most Dense layer of the Earth
Inner Core
100
What carries energy from one place to another?
Waves
100
What is the beginning location of an earthquake called
Epicenter
100
A comparison of how much matter there is in a certain amount of space. It’s a ratio of mass and volume
What is Density?
100
What is the vibration felt after an earthquake called?
Afterschock
200
What is the largest layer of the Earth ?
Mantle
200
Energy moves through…
A medium
200
What are the three types of waves that can be felt during the process of an earthquake?
primary waves, secondary waves, surface waves
200
What is the formula for Density?
Mass/Volume
200
Crack or fracture that forms between moving blocks of land
Fault
300
This layer of the Earth only makes up 1% of the layers of the Earth
Crust
300
A wave that has an amplitude, crest, and trough is what type of wave?
Transverse wave
300
These types of waves are the fastest type of seismic waves. They appear first when an earthquake occurs.
Primary Waves
300
Calculate the Density of Gold when its mass is 965g and has a volume of 50cm
19.3 g/cm^3
300
This is where the waves pulses are far apart
Rarefraction
400
What Layers of the Earth make up the lithosphere?
Crust and Upper mantle
400
A wave that has a compression and rarefraction is what type of wave?
Longitudinal wave
400
This type of wave is about half the speed of primary waves.
Secondary Waves
400
What is substance is the baseline for how desnse a material is. (whether it sinks or floats)
Water 1.0g/cm^3
400
What are large pieces of lithosphere that move on top of the asthenosphere called
tectonic plates
500
How do we know that the outer core is not a solid?
Because S waves cannot pass through it
500
This is where the waves pulses are far apart
Rarefraction
500
This type of wave causes the most damage and largest ground movements.
surface waves
500
How do you know if an object will float?
The Density of the object must be less than 1.0 g/cm^3
500
What do scientists use to study Earth’s interior
seismic waves
