This is a study guide for the next science test

QuestionAnswer
The general movements of the ocean waters are called ocean currents
The chief cause of ocean currents is the global winds
The turning of the earth makes the currents move at an angle
An ocean current turns about when it comes near a continent
In the part of the world you live in,the ocean currents move in direction clockwise
Ocean currents are classified as warm currents and cold currents
warm currents start near the equator
Cold currents start near the Poles
Name the 5 oceans on that study guide map. Pacific,Atlantic,Indian,Arctic,Antarctic
A group of connected waves are called wave train
A wave height is the distance between A crest and a trough
Waves are caused by tides,earthquakes,and wind.
Most waves are caused by winds
The distance wind blows over water is called its fetch
A wavelength is the distance between two adjacent crests and two adjacent troughs
Wave size is effected by wind speed,fetch,and time wind last
As a wave becomes a breaker,its wavelength decreases
As a wave becomes a a breaker,its wave height increases
Continental shelf hill were the ocean flat and then goes into a steep curve
Continental slope the sharp cut of of the continental shelf and it just drops.
Deep sea basin basin begin at the bottom of the ocean floor
Volcanic Mountain Mountain that sticks out of the water
Submarine canyon A big underwater mountain
mid ocean ridge mountains that run in the middle of the ocean
Plain Ocean floor flat areas
Most of earths water is found in the ocean
The ocean lies in huge basins
The part of the continent that is under the ocean is called the continental slope
The continental shelf slopes gradually
At the end of the continental slope,the ocean floor drops sharply
The deep sea basin starts at the end of the continental slope
Mountain ranges in the ocean are called mid ocean ridges
Valleys in the continental shelf are called submarine canyons
The deepest places along the ocean floor are trenches
The deepest trench in the world is the Marianas
Water planet Earth
Continental shelf low part of the continent that is covered by ocean
Plain flat area
trench deepest part of the earth
mid ocean ridges underwater mountain ranges
The earth is the only planet.......True of false false
only our planet has a lot of water true
the earths water layer is called the atmosphere false
the continental shelf has a gentle slant true
the continental slope has a gentle slant false
the deep sea starts at the begging of the continental shelf false
A submarine canyon is low place on the ocean floor true
A ridge is a high place on the ocean floor true
A submarine canyon is deeper than a trench false
The ocean floor has some flat places true
Most of the oxygen we breath come from phytoplankton
Plankton live in the ocean
The ocean supply most of the water vapor that returns to earth as rain and snow
Without the ocean our planet would be a dead planet
People eat many thing s hat live in the ocean,three examples are fish,seaweed,shellfish
Trash fish are fish that are not good to ______.They are made into___________ eat,fertilizer
Large deposits of _____ and _____ has been discovered along parts of water oil and natural gas
ocean water contains every known mineral
Three minerals we take from the sea are salt manganese and bromine
Phytoplankton supplies most oxygen to the earth
zooplankton floating sea animals
salt manganese and bromine some minerals we take from the sea
trash fish used for fertilizer
floating platforms used for oil drilling in the ocean
Green plants give of oxygen....true or false true
All green plants grow on land false
most of our oxygen come from zooplankton false
most of our oxygen come from phytoplankton true
plankton are large false
The ocean is a important source for food true
Seaweed is a food true
The ocean has only small deposits of oil false
Every mineral we use comes from the ocean false
Huge amounts of water evaporate from the ocean,this means the ocean can dry out false
