Question

Near a stream's source, a stream erodes a piece of rock from its streambed. as the rock is carried down the stream, how will its size and shape change? explain.

Answer 1

Volume of flow and the shape of its streambed

Answer 2

Answer:

Waterfall.

Explanation:

• When the stream comes out of the source of the river its speed is fast and it carries the pieces of the rocks and these rocks are then transported downwards with the help of gravity and this is a factor of the stream erosion and the process that creates this is the wave action and the action of the winds that changes the rise and the shapes of the landforms down under.

• Thereby deposits the stream load downwards there is a change in the size and the shape of the streams it moves downwards and discharges the water with high speed and this occurs by the hydraulic action and the abrasion as the tools of the weathering of the rocks.

• The bed load is slowed down along the stream floor, includes the heavier arts downwards form the sand, gravel to the pebbles. The saltation is a bounce-like movement, occurring when the river is flowing on the sides of the upper.
