You are watching: Streams erode their channels by abrasion by dissolving soluble material and by
1 The job-related of Streams Erosion – water causes loosened particles come be relocated through abrasion, grinding, or through dissolving soluble material. Sediment transport – sediments are relocated by the rivers and streams –In systems (dissolved load) –In suspension (suspended load) –Scooting or rolling follow me the bottom (bed load)
2 liquified Load dissolved substances enter the streams and rivers through groundwater and surrounding rocks. –The groundwater dissolves the rocks and also soil approximately it move to the present with dissolved material in it –Nearby absent sediments space dissolved and carried come the steams through runoff Streams it is provided a big amount of dissolved substances come the ocean.
3 Suspended pack Most common method of delivering sediments. –Small corpuscle (sand, silt, and also clay) are brought by the water towards the ocean. Throughout floods, the lot of sediments and also other materials brought in streams and also rivers boost dramatically.
4 Bed pack Pebbles that are found on the bottom of the stream/river. –Too heavy to it is in suspended or dissolved into the water, yet does relocate along the bottom as soon as the water move quickly. –Pebbles relocate on the bottom erode far themselves and also the channel digs the river deeper into the floor Checkpoint – –How execute streams transfer sediments? –How execute streams erode your channels?
5 Competence and also Capacity A stream’s competence is measured by the velocity of the water. –Competence – the dimension of the particles that the stream deserve to carry. –Velocity – the speed of the water. –Increases in velocity increase in competence. Capacity – the maximum amount load it have the right to carry and is established by water volume. –Increase the lot of water an ext particles carried. –Capacity is got to sediments drop the end of the water and also settle on the bottom.
6 Deposition The settling of corpuscle from the flow is recognized as deposition. Frameworks that form due to deposition –Deltas –Natural dams
7 Deltas An buildup of sediment wherein a stream beginning a lake or the ocean. –Water is close come the ocean slows down sediments space deposited –Sediments build up reduced off the route finds another path whereby the floor is reduced –One main channel (tributary) divides right into several smaller networks (distributaries).
8 organic Levees herbal levee – landform the runs parallel come a stream.

–Stream floods water overflows the riverbank water slows down –Water slows sediments drop out of the water –Accumulation the sediments top top the river bank increases the elevation of the bank a levee Checkpoint – define the formation of one of the landforms the streams develop by deposition.
