Final answer:
A point bar is a landform that develops along the inside of a meander in a river or stream due to deposition of sediment. Point bars are not set up or constructed by humans, but formed naturally. The formation of a point bar depends on various factors.
Step-by-step explanation:
A point bar is a landform that develops along the inside of a meander, a curve in a river or stream. It is composed of sediment, such as sand or gravel, that is deposited on the inner bank of the meander. The deposition of sediment forms a gently sloping bank on the inside of the curve.
The statement that a point bar should always be set up, no matter what shift, is false. Point bars are created by the natural processes of erosion and sediment deposition in rivers and streams. They are not deliberately set up or constructed by humans. The formation of a point bar depends on factors such as the speed of the water, the size of the sediment particles, and the geology of the area.
