Quizplus · Accepted Answer

Abrasion is the process in which sediment particles carried by a stream scrape and rub against the solid rock of its channel, polishing and wearing it away. This can lead to the formation of canyons or valleys in the rock over time. Scouring refers to the removal of loose sediment or debris from the streambed, while dissolution involves the chemical breakdown of rock minerals. Saltation refers to the bouncing or jumping of sediment particles along the bottom of the stream.
