Question

A meandering river flows across the floodplain

A tectonic event causes an uplift, causing the river to erode downward
Further incision by the river creates more entrenchment

Answer 1

A meandering river flowing across a floodplain experiences erosion and deposition. A tectonic event can cause uplift, leading to the river eroding downward and creating further entrenchment.

Step-by-step explanation:

A meandering river is a natural landform characterized by a winding and curving path. When a meandering river flows across a floodplain, it follows a pattern of erosion and deposition. In this case, a tectonic event causes the land to uplift, which leads to the river eroding downward. As the river continues to erode, it becomes more entrenched in the landscape.
