lithogenic
terrigenous sediments ()
land erosion
source of teriigenous sediments
terrigenous
most abundant sediment type
nertiz zone
terrigenous sediments dominate where
organisms
bigenous sediments source
calcareous ooze
plankton shells die and become what
pelagic zone (slope rise and abyssal plain)
bigenous sediments dominate where
oil and NG
biogenous sediments make what
silicon
animals take this element out of the water to make skeletal systems with biogenous
siliceous ooze
plankton with shells of silicon die and form what
Authigenic
hydrogenous sediments ()
clay
pelagic zone is mostly what
nertic
which zone would most likly be composed of larger sediments
bigger
the higher the velocity the______________the particles
30%
oozes contain how much bigenuos material
foraminiferons
amoeba like protists
pteropods
mollusks (sea butterflies or angels)
coccolithophore
single celled algae
4500
calcium carbonate deptrh( meters below sea level
calcareous
74500 meters below sea level...this ooze isnt found
acidity is high
ph is low means...
0-4500
between these numbers is where cal. ooze forms
all over
where can you fine cal. oozes
silicious ooze
formed by organisms containing silica
diatoms
single celled algae (silicious ooze)
radiolarins
amoeba like animals (silicious ooze)
diatoms and radiolarins
these 2 organisms contain silica tests
cold
diatoms (warm or cold)
hot
radiolarins (hot or cold)
orderly
how are continental margin sediments sorted
coast break
in continental margin sediments, larger particles are here and smaller particles are here
variable
thickness of pelagic sediments is highly
thicker
atlantinc ocean has a thicker/thinner than p. ocean
thicker
the abyssal plain is convered by a thicker/thinner layer of sediments that ocean ridges
turbites
what are layers of sediments called
slope and rise
most sediments is found here (2)`
biogenous and terrigenous
marine sediments are usually combonations of these
interplanetary dust, comets
two major sources of cosmogenous sediments
hydrogenous
materials that have precipitated directlyt to the seafloor
well
are sediments found in deep ocean poorly or well sorted
50 years
how long can clay remain suspended for
atlantic
bottom convered by thickness of about i km (a or P)
atlantic
more rivers (a or P)
atlantic
smaller area (a or P)
pacific
floor has avg thickness of less that 0.5 km ( a or P)
Pacific
thinner a or p
pacific
less rivers a or p
pacific
larger area a or p
pacific
trenches near land a or p
pacific
trap sediments a or p
evaporites
