How did the Earthquake say goodbye? He WAVED.
The detection of these types of waves allowed scientists to determine what the interior of the earth looks like
seismic
The largest layer of Earth's interior
Mantle
Frequency
Waves transport _________ through a _________
energy; medium
Detroit Zoo
The fastest-moving seismic waves
Primary (p-waves)
The layer made of solid iron-nickel alloy
Inner Core
Increased frequency causes this type of pitch
This type of wave compresses and expands the ground like an accordian
Longitudinal (or p-wave)
This is what causes Earth's inner metal core to remain in a solid state
High pressure
The second fastest moving seismic waves
Secondary (s-waves)
The layer that is responsible for maintaining Earth's magnetic field
Outer Core
Decreased frequency causes this kind of pitch
Low
The waves that vibrate side-to-side and up-and-down
Transverse (or s-waves)
Penguin
The type of seismic wave that is longitudinal
p-wave
Crust, Mantle, outer core, inner core; all solid except outer core
This measurement of the amount of energy of a wave
Amplitude
Types of waves that can travel through solids
Both p and s waves
This is the process that is thought to cause tectonic plate movement as well as earth's magnetic field
Convection currents
The type of seismic wave that is considered transverse
S-wave
A metal made by combining 2 or more metallic elements
Alloy
The distance between identical points on consecutive waves
Wavelength
Type of wave that can travel through both solids and liquid material
p-wave (longitudinal)
This is the rate of the increase in temperature with respect to increasing depth within earth's interior
What is geothermal gradient?
