How are seafloor sediments useful in reconstructing past ocean conditions? Choose all that apply. a. Biogenic oozes are composed of organisms that used to live on the seafloor, so their distribution provides information about deep-ocean conditions. b. Siliceous oozes on the seafloor indicate a warm surface ocean directly above the deposits. c. Sediments that accumulate on the seafloor provide information about ocean conditions at the time that the sediment was deposited. d. Calcareous oozes on the seafloor indicate a cool surface ocean directly above the deposits. e. Changes in the composition of the seafloor sediment reflect changes in the depositional environment.

    Answer: Options C & E

    Explanation:

    Option C : Sediments that accumulate on the seafloor provide information about ocean conditions at the time that the sediment was deposited

    Option E: changes in the composition of the seafloor sediment reflect changes in the depositional environment

    Seafloor sediments are useful in reconstructing past ocean conditions by:

    c. Sediments that accumulate on the seafloor provide information about ocean conditions at the time that the sediment was deposited.

    e. Changes in the composition of the seafloor sediment reflect changes in the depositional environment.

    Explanation:

    Seafloor sediments are the remainings found in the bottom of the ocean. These can come from organic or inorganic sources. The organic ones are formed from the rest of microorganisms, animals, or plants. While the inorganic can come from the earth, volcanic events, or minerals. Both inorganic and inorganic come from the ocean or the land outside the oceans. Therefore they can be used to explain the ocean conditions as well as the changes in the seafloor.
