Oceans Semester 1 Final Flashcards
This ocean has two sections, the Puerto Rico Trench, and the Mid-Atlantic Ridge
Atlantic
a small body of water or a broad inlet is an example of
bay
the circumference of the Earth was discovered through
angles of shadows
the albatross was the first vessel built with a sole purpose to
research oceanography
what is density stratification
when earth became a ball of hot liquid rock and elements separated according to density
a layer where convection currents happen, and rocks are partially melted and move slowly
mantle
divisions between geologic time periods are based on
older rock under younger rock
alfred wegner’s theory
continental drift
earth’s magnetic polarities have
all of the above
rock records show the following
an unpredictable pattern of symmetrical stripes in igneous rock
seafloor spreading is driven by
convection currents
what is not a tectonic feature
rivers
a mound of sediments that separate the continental slope from the ocean bottom
continental rise
ocean basins have the following items
all of the above
seamounts are underwater mountains that are usually volcanic, and they usually become
islands
the equation of Newton’s 1st Law
force = mass/acceleration
true or false: if forces are unequal, movement ALWAYS occurs
true
label the following image
a = centrifugal
b = gravitational
hydrostatic pressure is
a result of the weight of the water column pressing down on an object due to gravity
because the earth is _______ the water beneath the surfaces moves at an angle to the ________.
rotating, right
which shows water’s phases from freezing to boiling
solid, liquid, gas
which of the following is not an influence of salinity
condensation
a layer where the salinity changes rapidly with depth is
halocline
the thermoclines can be controlled by the following things
seasons and latitudes
equation for pressure
pressure = force/area
which two spheres impact the global conveyor belt
atmosphere, hydrosphere
surface waters move away from each other allowing deep water to move in is an example of
downwelling
if we are experiencing an La Nina winter, Idaho would be experiencing
colder weather
attraction between particles of the same substance is
cohesion
water is considered a _________ molecule with ________ bonds.
polar, covalent
seasons occur because Earth is close to the sun
false
what is not true
the freezing point of water is 0 degrees F
dark colored surfaces absorb more incoming solar radiation
true
water vapor, carbon dioxide, methane are examples of greenhouse gases
true
air moves from low to high pressure
false
an increase in the effect of a change is a negative feedback loop
false
climate is long term weather (the average)
true
doldrums occur at 30 degrees North and South
false
at the equator there is ______ direct sunlight and _____ rotation
more, faster
_______ occur when the tilt is either directly towards or away from the sun
solstices
ocean and atmosphere determine the distribution of all the following EXCEPT
evaporation
which of the following is NOT an example of a positive feedback loop
driving less - slows down warming - cleaner atmosphere - more change happening
wind is caused by…
Coriolis effect and pressure changing
which of the following indicate temperature
p = polar
in low pressure pockets, the type of weather we experience is…
moist
_______ occur in the North Pacific Ocean
typhoons
typhoons occur in the Indian ocean
false
