Which mechanism causes increased stream meandering as a river flows across a coastal plain?

💡 Explanation

When a river flows onto a coastal plain, its slope decreases because elevation drops and induces lateral erosion; this erodes more banks than deepens the channel. Therefore, meandering increases due to decreased slope, rather than increased bedload, the Coriolis effect, or vegetation, which have other effects.
