Answers
1
These can also move at the surface or deep in the ocean
wave
Fetch
Current
Thermocline
2
A wave is a movement of the water across the ocean.
The statement is true
A wave is a movement of energy across the ocean.
A wave is a movement of Air across the ocean.
A upswelling is the movement of the water across the ocean.
3
The slower the wind blows the fetch the larger the waves will be
The longer the spring tide, the larger the waves will be
The greater the density the larger the wave will be
The statement is true
Change slower to faster
4
The continents deflect ocean currents to the east and the west creating GYRES .
Change continents deflect to the Coriolis effect
Change ocean currents to waves
The statement is true
Change gyres to upwellings
5
Currents at the surface are usually generated by earthquakes.
Change earthquakes to wind
Change generated by earthquakes to the Coriolis effect
Change earthquakes to volcanoes
The statement is true
6
This technology located the Titanic, told the Historians the CONDITION of the Titanic’s hull.
Topax/Poseidon
RADAR
Side - Scan Sonar
Infrared Photography
7
The depth at which the wave no longer affects the water. This is equal to half the wavelength.
Water base
The Fetch
the Abyss
Thermocline
8
This will causes the high tide to be HIGHER, and the low tide to be LOWER
Neap Tide
Spring Tide
9
The tidal range is lowest during this time
Neap Tide
Spring Tide
10
f the day comes that you find yourself trapped in a RIP CURRENT.....WHAT CHA GONNA DO???
Dive deep underwater and escape the wave.
Turn around and swim back to shore
Swim to the side and get out of the rip tide
Ride the wave out to sea
11
Occurs when the Sun the Moon, and Earth form a right angle
Spring Tide
Neap Tide
12
Used by Scientist and historians to locate the wreck of the Titanic. What was it called?
SONAR
SUBMERSIBLES
INFRARED PHOTOGRAPHY
X-RAYS
13
The depth at which the wave no longer affects the water is called the fetch
No, change fetch to water base
Change fetch to Thermocline
Change fetch to Abyss
No, change fetch to Upwelling
14
greater tidal range during the winter in northern hemisphere, when Earth is closest to the Sun
Neap Tide
Spring Tide
15
Why do they call the waves that crash into the shoreline “Breakers”?
This is where most people go when they are on spring break
The incoming waves stablize and bottom out on the shoreline
National Break Dancers conference is held at the beach .
The incoming waves become unstable and their crest collapses
16
Differentiate a Gyre and an Upwelling
A gyre and an upwelling is basically the same thing
A gyre swirls water around. Upwellings bring up cold water.
A gyre is measured by fetch. Upwellings are measured by mass
A gyre goes down while an upwelling goes up
17
Why does salt water freeze at a lower freezing point than fresh water?
The salt creates a small gyre within the fresh water
A miracle!
The salt lowered the freezing point of the water.
The salt bonded with the water
18
What is or Who is the ALVIN?
Alvin is the leader of the first underwater biodome
A modern submersible capable of deep ocean depths.
The Alvin is the newest in Oceanographic satellites
He was the captain of the Challenger.
19
Speculate: Why does the dead sea have such a high salt content?
No fresh water coming in
Because everything has died
Too much animal life
This was a nuclear testing site
20
Explain how the ocean water probably came from Volcanic sources.
Water vapor was released by ancient volcanoes.
Cracks in the volcano called thermal vents spewed water
Water was released when the volcanoes were hit with comets.
Water leaked out of the hot lava
21
The top layer of the ocean is called the thermocline
The top layer of the ocean is called the surface layer
The top layer of the ocean is called the abyss
The statement is true
The top layer of the ocean is called the fetch
22
Salts are added to seawater by earthquakes and the WEATHERING of rocks.
Change weathering into creating
Change earthquakes to volcanoes
The statement is true
Change salts to acids
23
Explain the role of the Floats and the Topex/Poseidon as used by oceanographers.
the ocean’s surface temperatures are monitored
All are correct
the ocean currents are monitored
the wave conditions are monitored
24
During a DIURNAL TIDAL CYCLES Two high tides in a 24 hour period
Change diurnal tidal cycle to Lunar Tidal Cycles
The statement is true
Change Diurnal tidal to Summer tidal cycles
Change DIURNAL TIDAL CYCLES to SEMIDIURNAL TIDAL CYCLES
25
What is the relationship between the ocean water and a wave?
The wave carries the water to the shore
The energy bounces off of the wave
All are true
The wave carries energy through the water.
26
If a fetch of water contains both salt and fresh water, the fetch is said to be:
Transitional
Unlivable
Brackish
Intergraded
27
Describe a way we can use the ocean water in a fresh water situation:
Let the salt settle out of the ocean water then use the salt
Distill the water and use it for irrigation
Use magnets to remove the salt and then use the salt.
Run the ocean water through a filter and use it for drinking
28
Which of the following is
NOT
a chemical property of ocean water.
Ocean water contains silicon
Ocean water contains nutrients
Ocean water contains dissolved gases
Ocean water taste like salted coconut.
29
Solar tides cause high tides to be lower and low tides to be higher than normal
Spring Tide
Neap Tide
30
Which of the following is NOT an interaction between the Earth and the Oceans?
Providing food for the starving humans of the world.
Storing Carbon dioxide gas
Keeping the continents warm
Releasing of oxygen by photosynthesis
31
Why does the oceanic food chain begin at the surface area and not at the the thermocline?
There are no nutrients at the thermocline
There are too many predators below the thermocline
Sunlight cannot reach the thermocline
It is too hot at the thermocline
32
The sinking of warm water creates a current.
change sinking to rising
Change warm to cold
The statement is true
Change current to wave
33
During a full or new moon, the Sun, Earth, and Moon are all lined up
Spring Tide
Neap Tide
