A coastline characterized by gentle waves and minimal sediment transport is described as what?

• A. Low-energy Coast
• B. High-Energy Coast
• C. Lagoon
• D. Moraine

Answer: (A)

Wave energy along a coastline shapes how much sediment is moved and how fast erosion or deposition occurs. Gentle waves mean a low-energy regime, where there isn’t enough energy to transport much sediment or drive strong erosion. Sediment transport is minimal, so the coast tends to be relatively stable with slower change over time.

A high-energy coast would have stronger waves that move large amounts of sediment and cause more erosion, creating different features like cliffs or narrow beaches. A lagoon describes a sheltered water body behind a barrier and isn’t the description of the energy level of a coastline itself. A moraine is a glacial deposit, not a coastal feature.

So the best match for a coastline with gentle waves and minimal sediment transport is a low-energy coast.
