Divergent Plate
(extension)two tectonic plates that are moving away from
each other.
TERM 2
Convergent Plate
DEFINITION 2
is an actively deforming region where two (or more) tectonic
plates or fragments of the lithosphere move toward one
another and collide. (compresion)
TERM 3
Transform Plate
DEFINITION 3
faults neither create nor destroy lithosphere, is a type of fault
whose relative motion is predominantly horizontal in either
sinistral or dextral direction. (shear)
TERM 4
Magma
DEFINITION 4
rock capable of fluid flow
TERM 5
ocean and ocean which will be sub-ducted
DEFINITION 5
the older one
continental and continental which will be sub-
ducted
neither they are compressed and push upwards to form
mountains
TERM 7
paleomagnetism
DEFINITION 7
strips of alternating magnetic polarity at spreading
regionsPaleomagnetism is the study of the record of the
Earth's magnetic field in rocks, sediment, or archeological
materials.
TERM 8
Which feature was discovered the coast of
Monterey, California?
DEFINITION 8
a canyon
TERM 9
Animals in the deep ocean have developed
what trait?
DEFINITION 9
Bioluminescence
TERM 10
Hydrothermal vents
DEFINITION 10
are teaming with life, hot springs on an active oceanic ridge,
dissolve minerals and gasses escape through fissures and
vents
Active Continental
Margins
converginghigh EQ and volcanic activitypacificnarrower
TERM 17
Continental margin
DEFINITION 17
continental shelf, shelf beak, continental slope and contiental
rise
TERM 18
Continental Shelf
DEFINITION 18
Submerged extensions of continents, gently sloping seaward,
shaped by tectonics
TERM 19
Submarine Canyons
DEFINITION 19
a feature of some continental margins, they cut into
continental shelf and slope often terminating on the deep
sea floor in a fan shape wedge of sediment
TERM 20
Turbidity Current
DEFINITION 20
a fast dense current of water that carries sediment off shore.
EQ can trigger TC
Oceanic Ridge
a mountainous chain of young basaltic rock at an active
spreading ridge of an ocean.
TERM 22
Abyssal
Plain
DEFINITION 22
flat, cold sediment covered ocean floor between continental
rise and the oceanic ridge
TERM 23
Abyssal Hill
DEFINITION 23
Small sediment covered extinct volcanos or rock intrusions,
associated with seafloor spreading
TERM 24
Guyots
DEFINITION 24
flat topped seamount eroded by wave actions
TERM 25
Seamount
DEFINITION 25
volcanic mountains that rise from the ocean floor and never
grow tall enough to reach the surface, inactive
volcanosspreading centers or hot spots
Principle of Constant Proportion
the ratio of dissolved solids is constant even if the relative
amount are changing, oceans are in chemical equilibrium.
TERM 32
As the ocean absorbs more carbon dioxide is
it more or less acidic?
DEFINITION 32
more acidic
TERM 33
What are the two most abundant elements
dissolved in sea water?
DEFINITION 33
sodium and clhorine
TERM 34
What happens to pH when more carbon
dioxide is present?
DEFINITION 34
pH level decreases in the region
TERM 35
When the temperature of the ocean increases
what happens to the density?
DEFINITION 35
The density decreases
Weather
the state of the atmosphere at a specific time and place
TERM 37
Climate
DEFINITION 37
the long-term statistical sum of weather in an area
TERM 38
Humid air
DEFINITION 38
is less dense than dry air at the same temperature because
the molecules of water vapor weigh less than the nitrogen
and oxygen molecules that water vapor displaces
TERM 39
Gyres
DEFINITION 39
circuit if mid latitude currents around the periphery of an
ocean basin
TERM 40
Coriolis Effect
DEFINITION 40
shifts currents to the right of the wind direction in the
northern hempishereIn physics, the Coriolis effect is the
apparent deflection of moving objects when the motion is
described relative to a rotating reference frame.
Doldrums
the surface winds of th Hadley cells converge
TERM 47
Horse latitudes
DEFINITION 47
between the Hadley and ferrel cells, sinking air
TERM 48
ITCZ
DEFINITION 48
moves farther away from the equator during the northern
summer than the southern one due to the North-heavy
arrangement of the continents
TERM 49
Storms
DEFINITION 49
are variations in large-scale atmospheric circulation. Form
between two air masses or within one air mass
TERM 50
Hurricanes in the northern hemisphere rotate
which direction?
DEFINITION 50
counterclockwisewe drive no the right side of the road so
look at right hand, curl fingers around palm= CCW
Hurricanes in the Southern Hemisphere rotate
what direction?
Clockwise
TERM 52
What wind is associated with the Hadley
cells?
DEFINITION 52
Trade winds
TERM 53
What wind is associated with the Ferrel
Cells?
DEFINITION 53
Westerlies
