Question
Waves can travel across entire accan basins and so the waves at your beach might be from a storm half a world away,
The most famillar ocean waves are caused by the wind. These are wind-drives waves. This sort of motion is set up
anytime two fluids rub together, and remember that the atmosphere is essentially fluid. Waves caused by underwater
disturbances.such.as.earthquakes. landslides, or volcanic euptions are called tsunamis, These waves are typically tens
to hundreds of kilometers long. The gravitational pull of the sun and moon on the earth causes the sides which are
actually tidal waves.
QUESTION #1: Surface waves are orbital waves. A pelican is floating on the water, Describe the motion of the bird as it
rests on the water.
Let's review some parts of a wave. The following list refers to the figure below:
