Question

Quizplus · Accepted Answer

Large estuaries are usually formed when sea levels rise and flood river valleys, creating a drowned river mouth. This is more likely to happen on a submergent coastline, where the land is sinking or the sea level is rising. Emergent coastlines, where the land is rising or the sea level is falling, would not have as many large estuaries. Stable and retreating coastlines may have some estuaries, but they would not be as large as those on submergent coastlines.
