vocab
any disturbance that transfers energy through matter or empty space
wave
top part of the wave
crest
equation for wave speed
frequency x wavelength= Wave speed
What is the primary factor that determines the size of ocean waves
wind speed
describe one factor that causes water displacement/ a tsunami
Earthquake- when tectonic plates move together creating friction
underwater volcanoes
landslide
meteorite/ asteroid
A disturbance that transfers energy through ocean water
ocean waves
bottom part of the wave
trough
The speed of a wave is 65 m/s. if the wavelength of the wave is 0.8 meters, what is the frequency?
81.25 Hz
65/.8
what distinguishes a tsunami from regular ocean waves?
A tsunami forms when a large volume of water is suddenly displaced up or down/a series of waves that cause more damage
explain how a wave transfers energy through ocean water
The wind blows and energy is transferred in the form of waves. Water created ripples. waves don't carry water but rather transmit energy. This transfer of energy is how waves move through the ocean
A series of waves that form when a large volume of ocean water is suddenly moved up or down
tsunami
distance between one crest and another/ one trough and another
wavelength
A wave with a frequency of 500Hz is traveling at a speed of 200 m/s. What is the wavelength?
0.4 (200/500) ws=wl x f
draw an example of a wave Label the crest and trough, amplitude, and wavelength.
on board
why is it crucial to understand ocean waves
weather forecasting, climate change and plate tectonic movement
Carries energy through matter, such as water
mechanical waves
A measurement of how much time it takes for a wave to pass the fixed point
wave period
a wave with a frequency of 14 Hz has a wavelength of 3 meters. At what speed will this wave travel
42 m/s
14x3
describe the motion of water particles due to the action waves
They rise and fall in circular motions
As a wave moves into shallow water, what causes the top of the wave to break and topple over
contact with the ocean floor causes the wave to slow down and eventually break
