How do rivers shape distinctive landscapes through their processes and landforms?
Key Idea 1.2 (rivers): the processes that operate in a river landscape (erosion, transportation and deposition), how the long profile and cross profile change downstream, and the formation of distinctive fluvial landforms such as waterfalls, meanders, ox-bow lakes and floodplains.

What this dot point is asking
This dot point covers the river part of Key Idea 1.2 in WJEC Unit 1: how rivers shape distinctive landscapes. You need the processes (erosion, transportation, deposition), how the long profile and cross profile change downstream, and the formation of fluvial landforms (waterfalls, meanders, ox-bow lakes, floodplains). Expect to read these from OS maps, photographs and diagrams.

Q1. Name the four processes of river transportation. [Knowledge recall]
- Cue. Traction (rolling along the bed), saltation (bouncing), suspension (carried in the water) and solution (dissolved load).
Q2. Explain why deposition increases in the lower course of a river. [Short explanation]
- Cue. The gradient is gentle and the channel wide and shallow, so the river has less energy and drops its load, building floodplains and levees, especially when a flood spreads out across the valley floor.
Exam-style practice questions
Practice questions written in the style of WJEC exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.
WJEC Unit 1 (Theme 1)4 marksDescribe two processes of river erosion.Show worked answer →
A short data-response describe question. Reward two distinct erosion processes, each defined clearly.
Process one. Hydraulic action: the sheer force of moving water forces air into cracks in the bank and bed, weakening and breaking off material.
Process two. Abrasion (corrasion): the load carried by the river scrapes and grinds against the bed and banks, wearing them away.
Other valid processes are attrition (load particles knock together and become smaller and rounder) and solution (corrosion, where slightly acidic water dissolves soluble rock). Reward any two, clearly described.
WJEC Unit 1 (Theme 1)6 marksExplain the formation of a waterfall.Show worked answer →
A short explain question (levels marking). Reward a developed sequence linked by river processes; a labelled diagram helps.
Sequence. A waterfall forms where a band of hard rock lies over softer rock. The softer rock is eroded faster by hydraulic action and abrasion, undercutting the hard rock and leaving an overhang.
Development. The overhang of hard rock eventually collapses; a deep plunge pool is eroded at the base by abrasion and the swirling water. Over time this process repeats, so the waterfall retreats upstream and leaves a steep-sided gorge.
Top band. A clear, ordered sequence using named processes (hydraulic action, abrasion), with the plunge pool, retreat and gorge.
