Question

sea arch is the erosional landform of the River?​

Answer 1

Answer:

Another spectacular type

of erosional landform is the sea arch, which forms as the result of different rates of erosion typically due to the varied resistance of bedrock

Explanation:

Answer 2

Explanation:

As the river makes its way to the middle course, it gains more water and therefore more energy, so material can be carried in suspension and is used to erode the river banks. Lateral erosion starts to widen the river. When a river flows over flatter land it develops large bends called meanders.

As a river goes around a bend, most of the water is pushed towards the outside. This causes increased speed due to less friction and therefore increased erosion (through hydraulic action and abrasion).

The lateral erosion on the outside bend causes undercutting of the river bank to form a river cliff.

There is less water on the inside bend of a meander so friction causes the water to slow down, lose energy and deposit the material the river is carrying, creating a gentle slope.

The build-up of deposited sediment is known as a slip-off slope (or sometimes river beach).
