Surface Waves
Earthquake waves that travel both sideways (like P-waves) and up-and-down (like S-waves). Cause damage to man-made structures.
Period
amount of time it takes for one wave cycle to occur - from crest of one wave to crest of next
Wavelength
the distance between two consecutive and equivalent points on a wave
Wall of water
tsunami waves - the water actually moves, instead of energy moving through like normal waves
What causes tsunamis?
a massive disturbance that displaces water on a large scale and energy is released into the water. concentric circles!
Vigorous backwash
drag forces that pull the tsunami and debris backward and the water begins to flow in the opposite direction
Stripping of vegetation / soil
waves saturate soil with salt, ruins plans for years
Pollution
chemicals get dissolved and mixed in with sea water as debris gets picked up and backwash moves it out to sea
clastic rock
Sedimentary rock formed from bits and pieces of sediment pressed and joined (compacted and cemented) together over time.
NOAA
national oceanic & atmospheric administration
abiotic factor
Any nonliving part of the environment
