-
E.
Taylor–Proudman theorem
The Taylor–Proudman theorem is a fundamental result in geophysical fluid dynamics stating that in a rapidly rotating, inviscid, incompressible fluid, steady flows tend to be uniform along the axis of rotation, leading to columnar motion.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
