Question

Typical rate of accumulation of sediments on the deep-ocean floor range around ________ in 1000 years. answer 0.5-1 cm 2-5 cm 10-40 cm 2-4 m 12 m

Answer 1

in the middle of the ocean the sedimentation rate is as slow as 0.5 - 1 cm because the sediments are only from the wind, that was blown. then in continental margins, sedimentation rate is very fast at about 2-4 m per 1000 yr. so in deep ocean, sedimentation rate is about 2 - 5 cm per 1000 years.
