4. Which explanation best describes the development of a wave? (Points: 3)
Wind blows water along in one direction, thereby causing it to move great distances.
The air mixes with the water to produce a wave.
Friction between the moving air and the underlying water imparts energy, which causes the water to move horizontally great distances.
Friction between the moving air and the underlying water imparts energy, which causes the water to move in a circular motion, but the energy moves great distances. -
