Landscapes & Physical Processes
This mini-lesson covers Eduqas Theme 1 — Landscapes and Physical Processes: the distinctive landscapes of the UK (upland and lowland), how rivers erode, transport and deposit to create landforms (waterfalls, meanders, ox-bow lakes and floodplains), how drainage basins work, and how a distinctive landscape is managed for visitor pressure.
Work through each screen, answer the questions as you go (multiple-choice, short-answer and games) and collect ⭐ stars. Press Start when you're ready.
1.1 Distinctive UK landscapes
Upland and lowland Britain
Eduqas divides the UK into two broad types of distinctive landscape, and expects you to explain what makes each one look the way it does:
Upland (highland) landscapes — rugged, high relief, e.g. Snowdonia, the Lake District and the Scottish Highlands. Often shaped by past glaciation.
Lowland landscapes — gentle, low relief, e.g. much of southern and eastern England (the Fens, the Thames Basin), with wide river valleys and farmland.
Key idea: the main reason uplands are rugged and lowlands are gentle is geology — the type of rock — combined with the past processes (like glaciation) that have worked on it.
Geology & relief
Why geology shapes the scenery
Hard, resistant rock stands up to erosion, so it forms high ground; softer rock is worn down into lowlands.
Uplands are built from hard igneous (e.g. granite) and metamorphic (e.g. slate in Snowdonia) rock that resists erosion.
Lowlands are built from softer sedimentary rock (e.g. clay and chalk) that erodes more easily into gentle relief.

1.2 River landscapes
A river's long profile
Eduqas asks you to study a fluvial (river) landscape system. A river's journey from source to mouth is its long profile, split into three courses:
Upper course — steep, narrow, fast over rough rocks; middle course — gentler, wider; lower course — near-flat, wide and slow as it nears the mouth.
Key idea: in the upper course the river mainly cuts down (vertical erosion); further downstream it cuts sideways (lateral erosion) and increasingly deposits material.
River erosion
Four ways a river erodes
Rivers wear away their bed and banks by four main processes:
Hydraulic action — the sheer force of moving water pushing into cracks in the bed and banks, breaking rock apart.
Abrasion (corrasion) — the load (pebbles & sand) carried by the river scrapes against the bed and banks, wearing them away.
Attrition — the transported rock fragments knock against each other, becoming smaller and rounder over time.
Solution (corrosion) — slightly acidic river water dissolves soluble rock such as limestone.
Vertical vs lateral: in the upper course erosion is mainly vertical (deepening the valley); in the middle/lower course it becomes more lateral (widening it).
Transportation
How a river carries its load
The material a river carries is its load. It is moved downstream by four processes:
Traction rolls large boulders along the bed; saltation bounces pebbles; suspension carries fine sediment within the water; solution carries dissolved minerals.Match it

Upper course landforms
V-shaped valleys, waterfalls & gorges
In the upper course, powerful vertical erosion cuts a steep V-shaped valley with interlocking spurs (ridges the river weaves around). Where a band of hard rock lies over softer rock, a waterfall forms:
The soft rock is eroded (undercut) faster, so the hard cap rock overhangs. When the overhang collapses, the waterfall retreats upstream, leaving a steep-sided gorge.Explain it
Your turn — how a waterfall forms
✎Explain how a waterfall forms and retreats to leave a gorge. Use the words hard rock, soft rock, undercut and collapse.
Model answer
Where a band of hard rock lies over soft rock, the softer rock is eroded (by hydraulic action and abrasion) more quickly.
This undercuts the hard rock, which is left overhanging with no support beneath it.
Eventually the overhang collapses into the plunge pool, and the waterfall retreats upstream, leaving a steep-sided gorge behind it.
Middle course landforms
Meanders: eroding & depositing
In the middle course the river swings side to side in bends called meanders. Water flows fastest on the outer bend and slowest on the inner bend:
Fast flow on the outer bend erodes it into a steep river cliff. Slow flow on the inner bend deposits sediment as a gentle slip-off slope.
Watch out: erosion happens on the outer bank (river cliff); deposition happens on the inner bank (slip-off slope). Don't swap them round.

Erosion or deposition landform?
Tap whether each river landform is made mainly by erosion or by deposition.
Lower course landforms
Ox-bow lakes
As a meander gets more curved, erosion on the outer banks narrows the neck between two bends. In a flood the river cuts straight across, and the old loop is left behind as an ox-bow lake:
1 Erosion narrows the neck between bends. 2 The river breaks through the neck (usually in a flood), then deposition seals off the ends of the old loop, leaving a curved ox-bow lake.
In the lower course, the river also builds a wide, flat floodplain and raised banks called levées from sediment dropped during floods.
Explain it
Your turn — ox-bow lakes
✎Explain how an ox-bow lake forms from a meander. Use the words outer bank, neck, flood and deposition.
Model answer
Fast flow erodes the outer bank of each bend, so the meander becomes more curved and the neck of land between the bends grows narrower.
During a flood, the river has the energy to cut straight through the narrow neck, taking the shorter route.
Deposition then seals off the ends of the old loop, leaving it cut off as a curved ox-bow lake.
1.3 Drainage basins
Drainage basins of the UK
A drainage basin is the area of land drained by a river and its tributaries. You need the key vocabulary:
Source = where the river starts; tributary = a smaller stream joining it; confluence = where two rivers meet; watershed = the high edge of the basin; mouth = where the river meets the sea.
Basin as a system:inputs = precipitation; stores = water held in the soil, vegetation and rivers; flows/transfers move water through it; outputs = river discharge (to the sea) and evaporation.

Managing landscapes
Managing visitor pressure
Distinctive upland landscapes like the Lake District and Snowdonia are National Parks that attract huge numbers of visitors. This creates pressure that has to be managed:
Honeypot sites — a few especially attractive spots (e.g. a famous lake or peak) draw big crowds, concentrating the pressure.
Carrying capacity — the number of visitors an area can take before the environment is damaged.
Footpath erosion — thousands of boots wear away vegetation and soil, widening and gullying paths.
Management: footpaths are maintained (stone-pitching, boardwalks, resurfacing), visitors are directed along robust routes, and worn areas are fenced off to recover — balancing access with protecting the landscape.
