Task: Question Answering
Input (English): Background Paragraph: When waves travel into areas of shallow water, they begin to be affected by the ocean bottom. The free orbital motion of the water is disrupted, and water particles in orbital motion no longer return to their original position. As the water becomes shallower, the swell becomes higher and steeper, ultimately assuming the familiar sharp-crested wave shape. After the wave breaks, it becomes a wave of translation and erosion of the ocean bottom intensifies. 
Story: Two neighboring gulfs had different geographical features. South gulf has shallow water and is wider, while North gulf is quite deep. Both gulfs are exposed to intense wave activity throughout the year. 
Question: Which gulf experiences more free orbital motion disruption when waves hit?
Output (English): South.
