A and B

1

Which of the following are restoring forces?

Coriolis effect

Gravity from the Earth

All of them

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!

20 m/sec

10 m/sec

600 m/sec

0.5 m/sec

Factors that can affect the maximum size of a wave include

Wind Speed

Duration

Fetch

All of them

1

What factors are needed to get a fully developed sea?

Maximum size waves can have a high wind speed, long duration and a small fetch.

Maximum size waves can have a high wind speed, short duration and a large fetch.

Maximum size waves can have a high wind speed, long duration and a large fetch.

None of these will create a fully developed sea.

1

Fully developed seas can have waves that are bigger than maximum theoretical size.

They are called rogue waves and form from constructive interference.

They are called tides and form from constructive interference.

They are called tsunamis and form from destructive interference.

None of these are true; there can be no waves larger than those in a fully developed sea.

1

When a wave breaks on the shore...

Contact with the bottom causes friction and the height increases.

The crest is travelling more quickly than the trough

The crest collapses due to gravity.

All of these are true.

1

A tsunami wave...

has a speed of up to 600mph

speeds up as it approaches shallow water and interacts with the shore.

increases in height as it approaches shallow water

A and C

Tsunamis cause...

Massive flooding

Habitat Destruction

Loss of life

All of the above

1

A tsunami can be formed by

Earthquakes/Tectonic plate movements

Landslides/explosions

Volcanic activity

All of the above

1

Deep waves are ______ in shape with a motion. Shallow waves are _ in shape with a ________ motion.

Round, ellipse; pointed, circular

Pointed, circular; round, ellipse

Round, circular; pointed, ellipse

Pointed, ellipse, round, circular

Which statement is False about Tsunamis?

Tsunamis are more likely to occur in the Pacific Ocean.

Tsunamis are found more often in the “Ring of Fire”.

International tsunami detection systems are found in many locations in the ocean.

None of these are false. All are true.

1

Tsunamis don't destroy ships in the open sea because...

wave height in the deep ocean is very low - about 3 feet.

they don’t move through the sea.

the tsunami warning system gives ships time to get out of the way.

none of the above. Tsunamis frequently destroy ships on the open sea.

1

Tides are caused by

the Coriolis effect.

primarily the sun’s gravity, with some effect from the moon.

primarily the moon’s gravity, with some effect from the sun.

the sun’s gravity only.

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

Neap, Spring

Spring, Summer

Spring, Neap

Summer, Neap

1

Spring tides are different the neap tides because spring tides ____

have high tides that are higher and low tides are lower.

have very little change between high and low tide

occur during full and new moon

none of the above

1

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

Surging

Spilling

Plunging

1

Why does a wave break?

The trough of the wave drags on the bottom of the sand and slows down

The crest continues to move fast and eventually over runs the trough

The wave falls over due to gravity.

All of the above

Arrange the sequence of the event that leads to tsunami.

Disturbance that sends out a huge wave of energy into the water
Water recedes near the disturbance and waves with wavelengths up to several hundred miles long spread in all directions
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
