"Ocean Waves" Reading Guide

1. How is an ocean wave created?

• Ocean waves are created when wind blows across the surface of the ocean. This transfers energy from the air to the water.

• Ocean waves are created when wind oscillates.

• Ocean waves are created when wind blows across the surface of the ocean. This transfers matter from the air to the water.

• Ocean waves are created when magma rises from the mantle.

2. How does an ocean wave interact with a ship or surfer?

• The wave passes under the ship/surfer, lifting up onto the wave trough then lowering it into the wave crest.

• The wave carries the ship or surfer all the way to its destination.

• The wave passes under the ship/surfer, lifting it up onto the wave crest then lowering it into the wave trough.

• The wave passes over the ship/surfer.

3. What does the term oscillation mean?

• the distance between two waves (from crest to crest or trough to trough)

• the place where the wave crosses the resting line

• the lowest point of the wave

• a repeating pattern of motion

4. Choose the example of the object that does not oscillate.

• strings in musical instruments

• a pencil

• a fan

• a pendulum

5. What is the highest point (peak) of a wave called?

• trough

• crest

• resting line

• amplitude

6. What is the lowest point of a wave called?

• crest

• wavelength

• trough

• node

7. How does the water in an ocean surface wave move?

• The water in an ocean surface wave moves zig-zag.

• The water in an ocean surface wave doesn't move.

• The motion of water in an ocean surface wave is circular.

8. What travels with waves - energy or matter (solids, liquids, or gases)?

• energy

• matter

• both

9. What does a wave graph show?

• A wave graph shows the wave's energy as a repeating pattern of crests and troughs.

• A wave graph shows only the height of the wave, but not the wavelength.

• A wave graph shows where the energy is being transferred.

• A wave graph shows the type of energy being transferred.

10. What happens to ocean wave energy as it reaches the shore?

• The seafloor acts like a speed bump, and the height (amplitude) of the wave increases.

• The seafloor acts like a speed bump, and the wavelength of the wave increases.

• The seafloor acts like a speed bump, and the height (amplitude) of the wave decreases.
