Review Sheet for Aquatic Science Final Exam
Define:
Breaker- wave that begins to break upon nearing the shore
Surf- the area between the breaker zone and the shore
Storm surge- local rise in sea level near the shore
caused by strong winds from a storm
Tides- daily movement of water that change the level of
the ocean's surface
What is the formula for wave speed?
Wave
length (m) = Wave speed
Wave period (s)
Answer:
Salt water will become denser if there is an increase
in? The temperature
The gravitational pull that the moon exerts on the Earth is?
The main cause of high and low tides
What is the Coriolis Effect? The rotation of the Earth
What is a hurricane's storm surge caused by? Mainly high
winds
When are deep currents formed? They are formed when water density increases
Tidal range is greatest during? The Spring Tides
Where do whitecaps break in the ocean? They break in the open ocean
Where do longshore currents transport sediment? Mostly along the shoreline
What happens when waves come near shore? Usually their
wave height increases
What are surface currents formed by? They are formed by the wind
Where do neap tides occur? During the 1st and 3rd
quarters of the moon, when the sun, moon and earth form a 90 degree angle and
when the sun and moon have a maximum gravitational effect on earth.
What is El Nino? A periodic change in the location of
warm and cool surface waters
What is a tidal bore? A body of water that rushes up
through a narrow bay during the rise of high tide causing a very sudden tidal
rise.
When do Spring tides occur? When the moon is between the Earth and sun.
Define:
Continental slope- steepest part of the continental
margin
Continental rise- base of the continental slope
Continental shelf- flattest part of the continental
margin
Seamount- Individual Mountain of volcanic material on the
abyssal plain
Rift Valley- valley that forms in a rift zone between
diverging tectonic plates
Answer:
Which is the largest ocean? Pacific Ocean
Where would salinity of the ocean be at its lowest? Near the mouth of a river
How did the Earth have to change for the oceans to first
form? It had to cool off first
Where does sargassum come from? The oceanic zone
How does water below the surface get warmed if the sun only
warms the top 100m? Ocean
currents mix the water
Where does ocean pollution come from? Trash dumping, oil spills and
fertilizer
What is seaweed used in? most jellies, ice cream, lipstick and sushi
What item on the bottom of a seafloor can become a volcanic
island? A seamount
What former top-secret military satellite is used to measure
changes in the ocean? Geosat
What is one of the most abundant elements in the ocean? chlorine
Coral Reefs are known as the: "Rainforest of the
Sea".
Corals offer: food, shelter and safety from the predators
of the sea.
A polyp is: a tiny animal that looks like an upside-down
jellyfish
At night, polyps: emerge & wave their tentacles in
the water to catch microscopic organisms called plankton.
A mutually beneficial relationship is called: symbiosis.
Reef require specific conditions to grow:
*
High Salinity
*
Wave Action
*
Temperatures ranging from 68-82 Degrees Fahrenheit
*
Clear Waters
Three types of Reefs:
*
Fringing Reefs - form borders around the shorelines of islands
Example-
Hawaiian Islands
*
Barrier Reefs- separated from the shore by a shallow lagoon
Example- Great
Barrier Reef
*
Atoll Reefs- Ring-shaped reef formations that surround shallow lagoons
Example- Many
of them in the Pacific Ocean
Some coral reefs are capable of growing up to: 15 centimeters
a year.
Corals are damaged and destroyed by: pollution,
deforestation, fishing and collecting.
Coral belong to the group of animals called: Coelenterates.
Sharks skeletons are made of: cartilage
When a shark loses a tooth, it is: replaced by a new one
Sharks have very good: hearing, eyesight, taste, vision
The largest shark has: tiny teeth and does not chew its
food
Most sharks need to: swim to breathe
Sharks live: all around the world
Sharks have lived for: millions of years
Sharks can smell blood: up to 2 miles away
Most shark's eyes are located: near the front of their
heads.
Sharks cannot survive: without their fins
Sharks can taste by: rubbing up against something
Shark fins: help the shark in swimming certain directions
and keeps them from rolling over
Sharks have: 5-7 gills to help them breathe underwater
Cartilage is a: lightweight, rubbery material
Sharks use: camouflage as a way to hide or sneak up on
their prey
Sharks and rays: are in the same family
Sharks are: afraid of dolphins
Millions of sharks are killed each year for: food, such
as, shark fin soup
Sharks have a 6th sense: It's called Electroreception
Sharks pores are filled with: jelly, so it can help with
their Electroreception
Sharks sometimes eat: surfers because they look like
seals when on their surfboards
There are more than: 400 species of sharks around the
world
Wetlands provide a safe environment for many types of: fish,
birds and insects
Estuary ecosystems act as nurseries for about: 75% of
commercial fish species.
Wetlands provide types of vegetation such as: water
lilies, floaters, bulrushes and cattails
A factor that limits the productivity of estuary ecosystem
is: The depletion of oxygen in the sediments.
Wetlands provide humans with a place to: go hunting,
fishing, camping & observe birds
A swamp is a wetland with more open water surface and deeper
water than a: marsh
Wetlands are known to be important to water quality because
they: act as a water filter
Some major threats to wetlands are: human activity and
industrial development
Wetlands reduce the severity of: flooding in coastal
areas
Wetlands are "In-between" areas that have something of both dry uplands and open water
environments
Wetlands generally form in areas that are: lower in
elevation.
