How do waves form?
water gets more shallow towards shore and waves change in height. They get higher until they fall over and break.
What three factors cause waves to grow?
fetch - distance over water that wind blows
How does wave base affect the interaction of waves and coast?
interaction with sediments happen when you are shallower than wave base
What hazards do underwater sand bars potentially present?
measured crest to crest or trough to trough
waves come in at an angle to coast (called longshore currents)
when the wave interacts with the bottom it slows down and the rest of the wave catches up so it becomes parallel
