ACTUAL Exam Questions and CORRECT
Answers
Epipelagic zone - CORRECT ANSWER - first zone, aka sunlight zone, extends from
surface to 200 meters deep
Mesopelagic zone - CORRECT ANSWER - aka twilight zone, second zone, extends 200-
1,000 meters deep, only a faint amount of light
Bathypelagic zone - CORRECT ANSWER - third zone, aka midnight zone, extends 1,000-
4,000 meters deep
Abyssopelagic zone - CORRECT ANSWER - fourth zone, aka abyss, extends 4,000-6,000
meters deep, temp is near freezing
Hadal zone - CORRECT ANSWER - fifth and last zone, extends 6,000 meters-deepest
parts
sublimation - CORRECT ANSWER - solid to gas bypassing the liquid state
deposition - CORRECT ANSWER - gas to solid bypassing the liquid state
higher salinity means _______ water - CORRECT ANSWER - denser
higher temperature means _______ water - CORRECT ANSWER - less dense
deeper water is _________ shallow water - CORRECT ANSWER - denser than
, Low vapor pressure - CORRECT ANSWER - keeps earth's bodies of water from
evaporating quickly
high boiling point - CORRECT ANSWER - if water did have such a high one, it would be
a vapor at earth's temp
Lower density as a solid - CORRECT ANSWER - allows ice to float, which allows fish
and other sea life to live in very cold temps
What technology helped scientists discover mid-ocean ridges and further the evidence for
continental drift theory? - CORRECT ANSWER - sonar
what is the theory of plate tectonics - CORRECT ANSWER - the layer of the earth under
the crust, the mantle, moves through convection, so the solid plates resting on the mantle move
to.
The crust - CORRECT ANSWER - oceanic and continental move in large pieces called
plates due to the heat convection in the mantle
The mantle - CORRECT ANSWER - has the lithosphere which is the cool, solid top layer
and the asthenosphere which is the hot and soft bottom layer
The core - CORRECT ANSWER - Earth's internal heat, inner part is solid because of high
pressure and the outer part is a liquid iron nickel alloy
What are the seven plate boundaries - CORRECT ANSWER - antarctic, indo-australian,
pacific, south american, north american, african, and eurasian.
Where do plate boundaries occur? - CORRECT ANSWER - where the plates meet
How is plate movement measured? - CORRECT ANSWER - centimeters per year
