Question

A geologist aboard a deep-sea research vessel has collected several drill cores of oceanic crust from the bottom of the ocean. The cores are collected in order from east to west along the bottom of the basin and are labeled A1, B1, C1, and D1, respectively. Core A1 has 2.88 meters (m) of clay and siliceous ooze covering 4.86 m of pillow basalt. Core B1 has 2.37 m of muddy, clayey ooze covering 3.57 m of basalt. Core C1 has 2.11 m of clay and siliceous ooze followed by 3.2 m of basalt. Core D1 has 1.87 m of siliceous ooze over 2.54 m of basalt. Which core is closest to the mid-ocean ridge?A. A1B. B1C. C1D. D1

Answer 1

D. D1.

Step-by-step explanation:

Deep sea drilling is an Ocean drilling project which is carried out after geologists research the area. There are several crusts in the ocean and so drilling process can be difficult at times. Among the given cores, the lowest is for D1 which is 1.87m. This will be near to the mid ocean ridge.
