imagine arranging three of the red pressure blocks on the Figure 10A-7 ocean map sot they form a straight line on the warm Gulf Stream from east of northern Florida to approximately east of North Carolina. Align the red blocks to see the current along their bases on their northwest side. They represent warm water. and imagine three blue blocks, next to the red blocks, above the cold water between the warm Gulf Stream and the coast. The blue blocks represent cold water. A pencil laid on the middle red and blue blocks, perpendicular to the lines of blocks, would incline downward, it representing the sloping ocean surface. Water flows downhill and flowing water is acted upon by the Coriolis Effect, which would rotate the pencil to the right. The pencil now points in the direction towards which the water actually flows.

imagine arranging three of the red pressure blocks on the Figure 10A-7 ocean map sot they form a straight line on the warm Gulf Stream from east of northern Florida to approximately east of North Carolina. Align the red blocks to see the current along their bases on their northwest side. They represent warm water. and imagine three blue blocks, next to the red blocks, above the cold water between the warm Gulf Stream and the coast. The blue blocks represent cold water. A pencil laid on the middle red and blue blocks, perpendicular to the lines of blocks, would incline downward, it representing the sloping ocean surface.
Water flows downhill and flowing water is acted upon by the Coriolis Effect, which would rotate the pencil to the right. The pencil now points in the direction towards which the water actually flows. This current direction ______ consistent with the direction of motion of the Gulf Stream as you have observed in previous course investigations and mentioned earlier in this investigation.
a.is
b.is not
