Waves are Started by Disturbances Called
Swells
Tsunamis
Rogue Waves
Generating Forces
Earthquakes are a generating force for what kind of wave?
Swells
Capillary Waves
Tsunamis
Rogue Waves
The Primary generating force that creates waves is/are:
Landslides
Seismic Events
Wind
Meteor Impacts
When wind blows across the water's surface it creates friction which causes a drag along the water and forms small waves known as:
Capillary Waves
Rogue Waves
Spash Waves
Swells
True/False: Tsunamis can travel very long distances
False
True
Neither of the above
True/False: Waves can carry energy indefinitely
True
False
N/A
N/A
Which of the following causes the water surface waves to go back to an undisturbed state?
Generating Force
Splash Force
Kinetic Force
Restoring Force
Which of the following options make up the two disturbing forces? (Multiple Answers)
Capillary Action
Surface Tension
Adhesion
Gravity
Of the two restoring forces, which is more powerful?
Gravity
Surface Tension
True/False: Waves Transport Water from one point in space to another.
True--waves transport water
False--waves only transport energy
As a wave travel through the water it moves water particles up and down in a motion called:
Orbital Motion
Capillary Motion
Backwards Motion
Celerity Motion
The highest point of a wave is called the:
Trough
Amplitude
Wavlength
Crest
The height of wave is the distance between the crest and the:
Next adjacent crest
Trough
Period
H2o Molecule
Wave Speed is determined by the: (2 Answers)
Period
Frequency
Temporal Displacement
Wavelength
How do you compute wave frequency?
Wavelength Divided By Wave Period
Wavelength Multiplied by Wave Period
Crest Height Subtracted by Trough Distance
Square Root of Frequency Value.
Wave Cancellation Occurs When:
Wavelength is equal to Wave Period
The crest of one wave meets the trough of a another wave.
The Frequency is equal to the amplitude
When temporal displacement is equal to physical displacement
When two the crest of two waves collide, they add together to produce a higher wave. This is known as:
Wave Cancellation
Wave Displacement
Wave Reinforcement
Intermediate Displacement
True/False: There are two broad categories of waves:
(1) Deep-Water Waves
(2) Shallow-Water Waves
True
False
None of the Above
Whether a wave is considered deep water or shallow water depends on the: (Multiple Answers)
Temporal Displacement
Amplitude
Depth of the Water
Wavelength
True/False: A wave can transition from being a deep-water wave to a shallow water wave depending on the depth of the water:
True
False
None of the Above
Waves that are in between deep water-water and shallow-water waves are called:
Temporal Waves
EM Waves
Intermediate Waves
Alpha Waves
Which of the following is a type of Deep-Water Wave?
Splash Waves
Progressive Wind Waves
Gravitational Waves
Temporal Waves
Waves are Refracted as they move from _________ to ________
The Continental Shelf to the Abyssal Plain
Deep-Water to Shallow-Water
Shallow-Water to Deep-Water
None of the Above
What is Longshore Transport? (2 correct answers)
The process of Wave degeneration along a shoreline
The opposite of beach erosion.
Particles of water transported towards the shore and down the beach in the direction of the waves.
Is responsible for moving sand and sediments down a beach.
What are Tsunamis?
Progressive Waves generated by Wind
Rogue Waves generated by Storm Events
Large Waves generated by seismic events.
Large Waves generated by tidal forces.
True/False: All seismic events that occur on the ocean floor generate some form of Tsunami action.
True
False
Scientists use which of the following instruments to predict, detect, and track tsunamis: (Check all that apply).
Computer Models
Pressure Sensors Across the ocean
Temporal Incursion Devices
None of the Above
Not all waves form at the boundary of air and water. Waves that form under the surface are called:
Celerity Waves
Splash Waves
Internal Waves
Wind-Driven Waves
Standing Waves Do not progress across open water because they form in enclosed bodies of water.
True
False
Which of the following are responsible for the Earth's Tides (Check all that Apply0
Gravitational Pull of the Earth
Gravitational Pull of the Sun
Gravitational Pull of the Moon
Gravitational Pull of Stranglet Particles
The Sun has a greater gravitational than the moon but is 400 times farther away. Therefore, the effect of the sun on the tides is:
1/4 the strength of the Moon's
80% the strength of the Moon's
1/2 the strength of the Moon's
20% the strength of the Moon's
When the Sun and the Moon are lined up with one another, their effects add together. (Happens at Full Moons). This produces what kind of Tide?
Neap Tides
Displacement Tides
Solar Tides
Spring Tides
When the Sun and Moon are at Right Angles, their effects partially cancel one another, These tides are known as:
Temporal Tides
Neap Tides
Spring Tides
Summer Tides
Which if the Tides Result in the greatest Surge of water?
Spring Tides
Neap Tides
True/False: Spring Tides only occur in the Spring.
True
False
What is the length of a full Tidal Cycle?
31 Days
14 Days
17.5 Days
29.5 Days
Which of the following is a Tidal Pattern? (Check all that apply)
Diurnal
Annual
Mixed Semidiurnal
Semi Diurnal
Semi Diurnal Tides are Tides that occur:
One High and One Low Tide: Once a Day
One High Tide: Once a Day
One Low Tide Twice a Day
One High and One Low Tide: Twice a Day
Diurnal Tides are Tides that occur:
One High Tide and One Low Tide: Once a Day
Two High Tides and Two Low Tides: Twice a Day
Only High Tides: Once a Day
Only Low Tides Once a Day
Tides can Produce Waves that can be up to 8 m high. These waves are called:
Ebb Tides
Flood Tides
Tidal Compression Waves
Tidal Bores
