Ocean Waves

A giant wave from a sudden movement that makes waves go up and down

• surfing wave

• breaker

• tsunami

• crest

An ocean wave has a wavelength of 4 m and wave period of 2 s. What is the wave speed?

• 2 m/s

• 4 m/s

• 8 m/s

• 12 m/s

What is the source of most ocean waves?

• gravitational pull of the moon
• movement of plates
• energy of ocean currents
• motion of the atmosphere

Which statement correctly describes the motion of water particles due to the action of waves?

• they travel from one crest to another
• they move in opposite direction of the wave
• they rise and fall in a circular motion
• they move back and forth

What is the difference between a tsunami and other types of ocean waves?

• They form when a large volume of water is suddenly moved up or down.
• Wave energy of tsunamis increase as the water depth decreases.
• Tsunami is caused by the disruption of deep ocean currents.
• The wave height of a tsunami is much lower in the center of the ocean than it is near shore.

How are wave energy and water depth related?

• Wave energy increases as water depth decreases.

• Waver energy increases as water depth increases.

• Wave energy remains constant as water depth changes.

• Waver energy changes as water depth remains constant.

What is the maximum distance that a wave moves from its rest position?

• wave period

• wave speed

• wavelength

• amplitude

What is the forward motion of the particles that make up ocean water illusions?

• deep currents
• surface currents
• waves near the shore
• waves in the deep ocean

At what point does the circular motion of the water particles that make up an ocean wave stop?

• when the water depth = 1/2 of wavelength
• when the water depth = 2x the wavelength
• when the water depth = 4x the wavelength
• when the water depth = 1/4 of the wavelength

If a wave is traveling at 16 m/s and has a wavelength of 4 m, what is its wave period?

• 2s

• 4s

• 64s

• 8s
