Explanation:

Statement 1: On the surface of the earth, the horizontal tide generating forces are more important than the vertical forces in generating the tidal bulges.
The tidal bulges on wide continental shelves have greater height. In the open ocean tidal currents are relatively weak. When tidal bulges hit the mid-oceanic islands they become low.
Funnel-shaped bays greatly change tidal magnitudes.
Statement 2: Tidal currents occur in conjunction with the rise and fall of the tide. The vertical motion of the tides near the shore causes the water to move horizontally, creating currents. When a tidal current moves toward the land and away from the sea, it “floods.” When it moves toward the sea away from the land, it “ebbs.”
Tidal currents are the only type of current affected by the interactions of the Earth, sun, and moon.
