2 m/s
4 m/s
12 m/s
8 m/s
Which of the following correctly identifies each part?
I. crest, II. amplitude, III. wavelength, IV. trough
I. amplitude, II. crest, III. amplitude, IV. trough
I. amplitude, II. through, III. wavelength, IV. crest
I. wavelength, II. crest, III. amplitude, IV. trough
What distinguishes a tsunami from other types of ocean waves?
The wave energy of tsunamis increases as the water depth increases.
A tsunami is caused by the disruption of deep ocean currents by volcanic eruptions.
A tsunami forms when a large volume of water is suddenly displaced up or down.
The wave height of a tsunami is much lower in the center of th ocean than it is near the shore.
What is the scourge of most ocean waves?
Movement of techtonic plates
Gravitational pull of the moon
The energy of ocean currents
The motion of the atmosphere/wind
Which correctly describes the motion of water particles due to the actions of the waves?
Rise and fall in circular motion.
Travel form one crest to another.
They move in the opposite direction of the wave.
They move back and forth as each wave passes.
