Specification 3.1.3.3, 3.1.3.4 · Paper 1
Revise: River Profiles and Fluvial ProcessesErosion wears away material, transportation moves it, and deposition lays it down. Together, these processes help explain why rivers and their valleys change shape.
The carrying of rock and sediment from one place to another, for example on, within or beneath moving glacial ice.
Solution has two roles: dissolving rock is erosion; carrying the dissolved material is transportation.
Solution can mean erosion by dissolving rock or transportation of material already dissolved in the water. Make the meaning clear.

Specification 1.7 · Paper 1
Revise: River Physical ProcessesWithin the channel, erosion, transportation and deposition remove, move and lay down material. For example, weathering can loosen rock on a valley side, a slide can deliver it to the channel, and the river can then transport it downstream.
Specification 3.2a · Paper 1, Paper 3
The movement of sediment or dissolved material by water.
Revise: Geomorphic Processes: Weathering, Mass Movement, Erosion, Transport and DepositionTransportation moves sediment and dissolved material from one place to another. The method depends on particle size and weight, as well as the strength of the water flow.
