What is a tsunami?

A type of tidal wave caused by gravitational forces

A sudden rise in sea level due to strong winds

A large ocean wave caused by an earthquake or volcanic eruption

Where is kinetic energy in an ocean wave?

Within the moving water particles

At the top of the wave

Within the air pockets in the wave

At the bottom of the wave

1

Which type of motion describes the path of water particles in a wave?

Tidal motion

Circular motion

Linear motion

Vertical motion

What is the main difference between deep waves and shallow waves?

1

What is the main factor that causes a wave to break?

Wave height

Friction with the seafloor

Moon's gravity

Water temperature

1

What is a rip current?

Underwater currents caused by tides

Strong ocean currents moving away from the shore

A wave that moves against the general direction of the current

1

Tides are caused by the gravitational pull of the moon and the sun.

High tide occurs when:

Water level is constant

Water level is at its lowest point

Water level is unaffected by the moon

Water level is at its highest point

1

Low tide occurs when:

Water level is at its lowest point

Water level is constant

Water level is at its highest point

Water level is unaffected by the moon
