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
