Wave Characteristics
The distance between two adjacent crests of a wave
What is wavelength?
Caused by changes in the magnitude and direction of gravitational forces among the moon, Earth and sun
What are the tides?
Waves approaching a shore at an angle other than 90 degrees are...
What is refracted?
This rapid displacement of this can lead to a tsunami
What is water?
These are almost an illusion, as they move energy, not water
What are waves?
The valley between the crests of a wave
What is the trough?
Caused by wind blowing across the ocean surface?
What are wind waves?
As a wave enters shallow water this will increase
What is wave height?
Tsunami speed can best be described in this way
What is fast?
These particles move in closed circles as a wave passes
What is an orbital wave?
The time for one wavelength to occur
What is the wave period?
Caused by landslides, volcanic eruptions and seafloor faulting
What are seismic sea waves?
As a wave enters shallow water this will decrease
What is wavelength?
Tsunami period can best be described as this
What is very long?
This is what we call a wave whose form appears to be moving forward
What is a progressive wave?
The number of waves passing a fixed point per unit of time
What is wave frequency?
Storm surge or seismic waves in an enclosed harbor can cause this
What is seiche?
Waves approaching the shoreline are slowed down by this
What is the seafloor?
Tsunami steepness can be be described as this
What is NOT steep at all?
This type of barnacle is known for its long neck.
What is the goose barnacle?
This is proportional to wavelength
What is wave speed?
A wave traveling across the boundary of a fluid whose dynamics are influenced by surface tension
This ratio, when great, will cause a wave to break
What is the ratio between wave height and water depth?
These three warning systems alert people of tsunami
What are seabed seismometers, satellites and submerged devices?
This seabird was once classified as a fish, due to rumors about where the bird originated from.
What is the Barnacle Goose?
