Name the three steps in the water cycle
Precipitation, evaporation, condensation
Examples of mollusks
Cowrie, conch, sea snail, oyster, clam, mussel
Examples of crustaceans
Shrimp, lobster, crab
A fish that swims upright
Seahorse
Tides that occur when the sun and moon are at right angles to the earth and pull in different directions
Neap tides
The tide that occurs when the water has reached its lowest point before rising again
Low tide
The tide that occurs when the water has reached its highest point before it starts falling again
High tide
The tide that experiences the highest high tides and the lowest low tides
Spring tide
The area between low tide and high tide lines were most ocean plants and animals live
Intertidal region
All living creatures have to have some of this in their body tissues
Water
The smallest part of a substance that still has the quality of that substance is a
Molecule
The ocean covers almost how much of the earth’s surface?
Three fourths
Underground places where water collects
Aquifers
Single shell
Univalve
Two shells
Bivalve
A small crustacean that is a scavenger
Shrimp
This produces pearls
Oyster
A carnivorous crustacean with two large pincers
Lobster
A crustacean that runs sideways
Crab
Why is water vapor in the air not as salty as ocean water?
When water evaporates from the ocean most of the minerals dissolved in the water remain behind
How does the ocean moderate the climate of earth?
The temperature of the ocean does not change as quickly as that on land. Therefore, the ocean warms the land in the winter and cools it in the summer.
Which Penguin incubates the penguin egg?
The father
The parent penguin stores food for its baby in this
It’s crop
How long do penguins walk from the edge of the ice to their rookery?
30 to 40 miles
Small fluffy feathers beneath the long outer feathers that keep penguins warm even an icy weather
Down
The science that studies the complex relationships between living things and their surroundings
Ecology
During an oil spill the thick layer of oil that forms
An oil slick
This breaks oil into small drops that can be washed away from shore in the event of an oil spill
Detergent
Scientists who study the sea
Oceanographers
Birds and seabirds belong to the group of animals with backbones called
Vertebrates
This sea animal floats on its back to carry its baby and to eat food
Sea otter
This pinniped has a flap of skin that dangles from it snout that looks a little like a trunk
The elephant seal
This pinniped male can be 16 to 20 feet long and weigh 5000 to 8000 pounds
Male elephant seal
This pinniped weighs over 2000 pounds with a blunt forehead, wide snout, and long tusks
Walrus
When undisturbed this fishes spines lay flat against its body but when it feels threatened it puffs itself up with water so that it’s spines stick out making it difficult for a predator to swallow it
The porcupine fish
This fish is one of the most beautiful fish found in tropical waters. It has very strong poison that is effective even after it is dead.
The lionfish
This male fish has a pouch to carry eggs deposited by the female
The sea horse
There are more than 4600 kinds of this crustacean
Crabs
The growing process crustaceans go through during which they shed their shells
Molting
The valuable lining of the shells of clams, mussels, and oysters used to make buttons and jewelry
Mother of pearl
Two matching shells joined by hinges
Bivalves
Where kelp often grow
The low intertidal zone
An invertebrate and carnivorous snail that preys upon the colonies of mussels
The whelk
A sea animal that lives in the low intertidal zone that looks like around flower but is actually an animal. Its waving tentacles contain deadly cells that release venom that paralyze shellfish or small fish
Sea anemone
Red and purple prickly balls that graze on kelp
Sea urchins
This shell can be made into a musical instrument
Conch shell
These live in the high intertidal zone
Barnacles
This algae plant lives in the middle intertidal zone
Seaweed
These look like berries and help some larger algae to float
Air bladders
On algae, these take the place of roots and anchor the plants to the ocean bottom
Holdfasts
Invertebrate animals that cement themselves to rocks and grow a very hard shell
Barnacles
Any form of water rain, sleet, hail, or snow that comes down from the clouds
Precipitation
Water vapor changing back to a liquid
Water condensation
The transforming of liquid water into water vapor
Evaporation
A water molecule has this structure
Two hydrogen atoms and one oxygen atom
The smallest part of a substance that still has the qualities of that substance
A molecule
Mountainous waves caused by earthquakes that destroy all that lies in their path
Tsunamis
Tiny floating plants and animals in the ocean that are food for ocean life
Plankton
