Which of the following BEST describes the definition of a wave?

(1 point)
Responses

currents of energy flowing because of density

currents of energy flowing because of density

movement of water in a defined direction

movement of water in a defined direction

energy moving through a fluid

energy moving through a fluid

transport of water through the oceans

transport of water through the oceans

The response that BEST describes the definition of a wave is:

energy moving through a fluid

This definition captures the essence of what a wave is, as waves represent the transfer of energy through a medium, such as water, without the permanent movement of the medium itself.

To calculate the wavelength, what measurement of a wave would you need?

(1 point)
Responses

the ratio between the height and the length

the ratio between the height and the length

the distance between two adjacent waves

the distance between two adjacent waves

the surface depth of the ocean floor

the surface depth of the ocean floor

the distance between the crest and the trough

the distance between the crest and the trough

To calculate the wavelength, you would need:

the distance between two adjacent waves

Wavelength is defined as the distance between consecutive points of the same phase on a wave, typically measured from crest to crest or trough to trough.

Which statement BEST summarizes why a wave breaks?

(1 point)
Responses

The distance between two waves becomes larger.

The distance between two waves becomes larger.

The wave dips below another wave along the coast.

The wave dips below another wave along the coast.

The wavelength is bigger than the depth of the water.

The wavelength is bigger than the depth of the water.

The wave gains speed from winds and ocean currents.

The statement that BEST summarizes why a wave breaks is:

The wavelength is bigger than the depth of the water.

Waves break as they approach shallow water because the wave's speed decreases and its height increases, leading to instability and ultimately causing the wave to break when the height exceeds a certain limit relative to the water depth.

Lilah loves to skip rocks on lakes—her record is 21 skips! What type of wave does she create on the surface when she skips rocks?

(1 point)
Responses

capillary

capillary

surface

surface

tidal

tidal

breaker

The type of wave Lilah creates on the surface when she skips rocks is:

surface

Surface waves are generated on the water's surface when an object (like a rock) disturbs the water, causing ripples that spread out from the point of impact.

Nathan is shocked to find out that there is a huge patch of garbage floating in the northern Pacific Ocean. What causes this phenomenon?

(1 point)
Responses

biological cycles

biological cycles

turbidity currents

turbidity currents

carbon reservoirs

carbon reservoirs

ocean gyres

The phenomenon of a huge patch of garbage floating in the northern Pacific Ocean is caused by:

ocean gyres

Ocean gyres are large systems of rotating ocean currents that can trap and concentrate debris, including plastic and other types of garbage. The Great Pacific Garbage Patch is a well-known example of this effect.
