Explanation:
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.
It's B. The exact coordinates are: 18°56'S and 47°31 'E
In this example, the biosphere is very dependent on the hydrosphere.
