Which statement accurately describes how wind and current affect a boat?

• A. The wind affects the boat's movement from above the water, while the current affects the area below the water.
• B. The wind and current both affect only the surface portion of the water.
• C. The wind affects below the water, and the current affects above the water.
• D. The wind does not affect movement, only current does.

Answer: (A)

Wind acts on the boat from above the water, mainly through sails, while current is the movement of the water itself that the boat rides through, affecting it within the water column, including below the surface. This distinction shows how each force interacts with a vessel: wind provides propulsion and direction from above, while current moves the boat through the water itself. The other statements mix up where the forces act or deny one of the effects—for example, current isn’t limited to the surface, wind does affect movement, and wind acts above the water rather than below.
