Which term describes the underwater movement of water caused by wave action near shore?

• A. Surge
• B. Currents
• C. Tide
• D. Upwelling

Answer: (A)

Surge describes the shoreward movement of water caused by wave action near the shore. When waves break, they push water toward the beach, creating a brief, energetic rush that travels toward the shore. This shoreward water movement is distinct from general currents (which can flow in various directions over larger areas), tides (the regular rise and fall of sea level driven by gravity), and upwelling (vertical movement bringing deep water to the surface, usually driven by wind). The surge specifically captures that immediate, nearshore water movement produced by breaking waves.
