As a ship moves through the water, it causes a wake, which is also moving forward relative to the sea. In addition to a fore and aft motion, this wake also has a(n) _______________.

A downward and inward flow
B upward and inward flow
C downward and outward flow
D upward and outward flow
AI Explanation

The correct answer is B) upward and inward flow. As a ship moves through the water, it creates a wave pattern known as a wake. This wake has both a forward and a lateral motion. The lateral component of the wake flow is characterized by an upward and inward flow pattern. This is due to the displacement of water caused by the ship's hull, which creates a low-pressure zone on the sides of the vessel, drawing the water inward and upward. The other answer choices are incorrect because they do not accurately describe the lateral flow pattern of the wake. Option A describes a downward and inward flow, which is not the case. Options C and D describe a downward and outward flow, or an upward and outward flow, respectively, which are also not accurate descriptions of the wake's lateral flow.
