Waves and Tides TEST

In a diurnal tide, time from high tide to high tide averages 6 hours and 12.5 minutes.

An ocean wave is an energy transmission that moves water along with the energy.

Galveston has spilling breakers along its beaches.

Ebb currents are incoming tide flow. Flood currents are outgoing tide flow.

Restoring forces create waves, and disturbing forces destroy waves.

White caps are the white part of a wave when the wave breaks on a beach or obstacle.

What type of wave is created as energy travels through water?

Wave speed is equal to..

Which of the following are disturbing forces?

Which of the following are restoring forces?

If a wave has a wavelength of 60 meters, height of 30 meters, and a period of 6 seconds, what is the speed/velocity of the wave? Think carefully!

Factors that can affect the maximum size of a wave include

What factors are needed to get a fully developed sea?

A single high and low tide daily is called a ____ tide. Two unequal high and low tides daily is called a ____ tide.

During ____ tides the sun and moon align relative to Earth. During ____ tides, they are at right angles to Earth.

Wave breakers crash gently or violently on the beach. Which type of breaker is the most dangerous?

Why does a wave break?

Match the label to the correct part of the wave.

Which part of the tsunami wave reaches the shore first?

Arrange the sequence of the event that leads to tsunami.

1. Water recedes near the disturbance and waves with wavelengths up to several hundred miles long spread in all directions
2. Waves slow down to about 45 mph due to bottom friction but there is still a huge amount of energy so it piles up and the wave increases in height up to 50 feet As the top crest of the wave moves faster than the bottom trough, the waves increases in height and break, smashing onto land with an enormous amount of energy pretty much destroying everything in its path
3. Disturbance that sends out a huge wave of energy into the water
