Question

ocean waves and tides
a. parts of a wave

1. the highest part of a wave is the crest
2. the lowest part of a wave is the trough
3. the vertical distance between a crest and a trough is the wave height
4. the horizontal distance between two consecutive crests or two consecutive troughs is the wave length

b. surface waves

1. surface waves are caused by the ________________ blowing over water. the size of a surface wave depends on wind speed, the length of ________________ the wind blows, and distance.
2. the motion of water particles in a wave is ______________________
3. a surface wave becomes a(n) __________________ when it collapses near the shore.

Explanation:

1. Surface waves are wind - generated. Their size is determined by wind speed, duration of wind - blowing, and fetch (distance).
2. Water particles in a wave move in circular orbits.
3. When a surface wave collapses near the shore, it becomes a breaker.

Answer:

1. Wind; duration
2. Circular orbits
3. Breaker
