They are formed by several factors along the time, including weathering.
One of the ways is that it carves it by weathering and eroding it away.
Landforms formed by rivers include canyons, valleys, meanders, deltas, and floodplains. Rivers shape the landscape through erosion, transportation of sediment, and deposition, creating a variety of distinct land features.
Weathering breaks down rocks and minerals along the riverbanks, contributing to the erosion process. This helps to shape the land by loosening and transporting sediment downstream, leading to the formation of channels and valleys. Over time, weathering along rivers can carve out canyons and shape distinct landforms.
Draw a shape. Every time your pencil changes direction, an angle is formed. A rectangle has four corners, all right angles.
Faster river velocities are capable of carrying greater amounts of bedload and transporting them farther and faster. The shape of the sediments of the bedload would therefore be exposed to more physical weathering which would progressively round the sediments and also decrease their size.

Probably weathering and/or erosion.
False. Physical weathering is the type of weathering in which the physical properties of a material are altered without changing its chemical composition. This can include changes in size, shape, or texture.
A hill is typically formed by a combination of geological processes, such as erosion, weathering, and tectonic activity. Over time, these processes can uplift and shape the land to create elevated areas known as hills.
Weathering rounded the mountains by breaking down jagged peaks.
