Waves
What is the highest part of a wave called?
What is The crest
What is the term for the daily rise and fall of the ocean's water level?
What is Tides
What is the primary source of energy that generates most ocean waves?
What is The wind (or the sun, which heats the Earth and creates wind!)
What is the highest point of a wave called?
What is the crest?
Which object has a stronger gravitational effect on Earth's tides: the Sun or the Moon?
What is The Moon (because it is much closer)
What usually causes ocean waves to form?
What is Wind
What is the term for the tide when the water reaches its highest level on the shore?
What is High tide
The size of a wind-driven wave depends on wind speed, wind duration, and this term, which means the distance of open water the wind blows over.
What is Fetch
What is the lowest point of a wave called?
What is The trough
How many tides are there
What is four
What is a giant, powerful wave caused by an underwater earthquake or volcanic eruption called?
What is A tsunami
How long does it typically take to transition from one high tide to the very next high tide?
What is About 12 hours and 25 minutes (accept 12 and a half hours)
These specific, extra-strong tides form when the Earth, Sun, and Moon align in a straight line during a New or Full Moon.
What is Spring tides
What is the horizontal distance between two consecutive crests or two consecutive troughs called?
What is Wavelength
What changes the tidal force?
What is the moon cycle
As a wave approaches the shore, what happens to its height and speed?
What is It gets taller (height increases) and slows down.
What do we call the specific area of the shoreline that is underwater during high tide but exposed to the air during low tide?
What is The intertidal zone (or littoral zone)
These weaker tides form when the Sun and Moon are at right angles to each other (during a quarter moon), pulling the water in different directions.
What is Neap tides
What is the vertical distance from a wave's trough to its crest called?
What is Wave height
Besides gravity, what outward force caused by Earth's rotation helps create the tidal bulge on the side of Earth away from the Moon?
What is Inertia (or centrifugal force)
Waves transfer ________, not water mass, across the ocean surface.
What is Energy
Because the Earth rotates through two tidal bulges each day, most coastal areas experience what specific pattern of tides?
What is Semidiurnal tides (two high tides and two low tides each day
What type of dangerous, narrow current forms when water rapidly rushes back out to sea through a break in a sandbar?
What is A rip current (or rip tide)
What is the term for the amount of time it takes for two consecutive wave crests to pass a fixed point?
What is Wave period
What is the term for a true tidal wave—a noticeable wave or wall of water that travels up a river or narrow bay against the current as the tide comes in?
What is A tidal bore
