HookThe Holderness coast loses two metres of Britain every year
The Holderness coast in East Yorkshire is the fastest-eroding coastline in Europe. On average it retreats around two metres every year — and in a single stormy winter it can lose far more. Since Roman times some four kilometres of land have vanished into the North Sea, taking around thirty villages with them, their names now marked only on old maps of the sea floor. The reason is written into the rock: Holderness is made of soft glacial boulder clay, dumped by ice age glaciers, which slumps and washes away almost as fast as the waves can reach it.
That single fact — that the shape of the land depends on the rock it is made of and the processes working on it — is the backbone of physical landscapes in the UK. Hard rock resists and forms cliffs and headlands; soft rock retreats and forms bays and vanishing coastlines. The same logic governs rivers carving valleys and glaciers gouging out lakes. This topic asks you to read a landscape like a detective: identify the processes (erosion, transport, deposition, weathering), recognise the landforms they build, and understand how people try to manage the change — because a coastline or floodplain that keeps moving is also a place where people live, farm and build. Learn the processes first, and every landform becomes a logical consequence rather than a list to memorise.
ModelThe shape of the UK — upland and lowland
The UK's physical landscape divides roughly along a diagonal. The upland areas — higher, older, harder rock — lie mostly to the north and west: the Scottish Highlands (topped by Ben Nevis at 1,345m), the Lake District, the Pennines (the 'backbone of England'), Snowdonia in Wales and Dartmoor in the south-west. The lowland areas — flatter, younger, softer rock — spread across the south and east, where most of the population and farmland sit.
Across this relief run the UK's major rivers. The Severn, at about 354km, is the longest; the Thames drains the south-east; the Trent and others thread the lowlands. Rivers begin in the uplands as fast, narrow streams and end at the coast as wide, slow, sediment-laden channels — a journey that shapes the landforms in the next two blocks.
The reason to start here is that geology explains the pattern. Hard, resistant rocks such as granite survive as the uplands and coastal headlands; soft rocks such as clay are worn down into lowlands and bays. Whenever an exam hands you a map or photograph and asks you to describe a landscape, this upland–lowland, hard–soft framework is the structure that turns a vague description into geography.
MechanismCoastal processes and landforms of erosion
Coasts are shaped first by waves. Constructive waves are low and long, with a strong swash that pushes material up the beach and builds it. Destructive waves are tall and steep, breaking with a powerful backwash that drags material away and erodes. Weathering weakens the rock in place — mechanical freeze-thaw prises cracks apart, chemical carbonation dissolves limestone — while mass movement (rockfall, sliding, slumping) drops loosened material down the cliff.
Waves erode by four processes: hydraulic action (the sheer force of water compressing air in cracks), abrasion (rocks flung against the cliff like sandpaper), attrition (rocks knocking together and rounding down) and solution (chemical dissolving). Where a coast has alternating hard and soft rock (a discordant coast), the soft rock erodes back into bays while the hard rock juts out as headlands — the classic pattern along the Dorset coast around Swanage.
Headlands then erode in a predictable sequence. Waves attack lines of weakness to open a crack, then a cave; the cave is driven through the headland to form an arch (Durdle Door in Dorset); the arch roof collapses to leave a stack (Old Harry Rocks); and the stack is undercut until it falls, leaving a stump. Meanwhile the base of a cliff is eroded to form a wave-cut notch, the cliff collapses, and the process repeats, leaving a wave-cut platform at its foot. This crack–cave–arch–stack–stump sequence is one of the most commonly examined chains in the whole course.
CaseCoastal deposition and management — Dorset and Holderness
Where waves lose energy, they deposit. Material is moved along the coast by longshore drift: waves hit the beach at an angle, the swash carries sediment up the beach diagonally, and gravity pulls the backwash straight back down, edging material along in a zigzag. This builds beaches, and where the coastline changes direction it builds a spit (a finger of sand and shingle — Spurn Head at the end of the Holderness coast); a spit growing across a bay becomes a bar.
Because coasts erode where people live, they are managed, and AQA wants an example of a management scheme. Hard engineering works against the sea: sea walls, rock armour (rip-rap), gabions and groynes that trap beach material. Soft engineering works with natural processes: beach nourishment (adding sand), dune regeneration, and managed retreat, deliberately letting low-value land flood to absorb wave energy.
On the Holderness coast, the soft boulder clay retreats about two metres a year. At Mappleton, rock groynes and a rock revetment built in 1991 protect the village and its road — but by trapping sediment they starve the coast further south, speeding erosion there. That knock-on effect is the evaluation examiners love: coastal management protects one place at another's expense, so decisions must weigh the cost of defence against the value of the land, and no scheme is a free win.
Coastal questions almost always test a rate, so practise the arithmetic. Holderness retreats at roughly 2m per year. Over the 2,000 years since Roman times that is \(2 \times 2000 = 4{,}000\) m — about 4km of lost land, which matches the lost-village evidence. Now flip it into a planning judgement: a farmhouse sits 50m from a cliff edge retreating at 1.8m per year. Time until the cliff reaches it is \(50 \div 1.8 \approx 27.8\) years. The mark is in the interpretation — the average hides the danger, because a single severe storm can strip 5–10m in one night, so the house is at real risk well inside a decade even though the 'average' suggests nearly 28 years. Quoting the rate and warning that averages smooth out damaging extremes is exactly the AO3 reasoning that lifts a data answer into the top band.
MechanismRiver landforms down the long profile — the River Tees
A river's long profile runs from steep source to gentle mouth, and its work changes along the way. In the upper course, the river erodes vertically, cutting a steep V-shaped valley with interlocking spurs. Where it crosses a band of hard rock over soft, it undercuts the soft rock to form a waterfall — High Force on the River Tees plunges about 21m — and as the waterfall retreats upstream it leaves a gorge.
In the middle course, the river erodes laterally (side to side) and develops sweeping meanders. The fast current on the outer bend erodes a steep river cliff; the slow water on the inner bend deposits a slip-off slope. When a meander loops so tightly that the river cuts across the neck during a flood, the loop is sealed off as an ox-bow lake — the Tees has classic examples near Yarm.
In the lower course, the river is wide and slow and mainly deposits. It builds a broad, flat floodplain; repeated floods drop the coarsest sediment at the banks to raise natural embankments called levées; and at the coast the river widens into an estuary (the Tees estuary), where mud is deposited in tidal flats. The four transport processes carry the load throughout: traction (rolling), saltation (bouncing), suspension (carried in the flow) and solution (dissolved). Learn the Tees as one river from High Force to estuary and you have a single, joined-up case study for every fluvial landform.
DataRiver flooding, hydrographs and management
When a river receives more water than its channel can hold, it floods. A flood hydrograph is the tool for analysing this: it plots river discharge (the volume passing a point, in cumecs) against time after a storm. The rising limb shows discharge climbing, the peak discharge is the maximum, and the lag time is the gap between peak rainfall and peak discharge. A flashy hydrograph — short lag, high peak — means water reaches the river fast and flood risk is high.
Lag time is shaped by both physical and human factors. Steep slopes, impermeable rock, saturated ground and heavy prolonged rain all shorten it; so does urbanisation, where tarmac and drains rush water into the river instead of letting it soak in, and deforestation, which removes the trees that would intercept rain.
Management again splits into hard and soft. Hard engineering includes dams and reservoirs, raised embankments, channel straightening and flood-relief channels. Soft engineering includes flood warnings, floodplain zoning (keeping building off the highest-risk land), afforestation and river restoration. AQA wants an example scheme: the Banbury flood scheme on the River Cherwell (completed 2012, around £18.5m) built an earth embankment and a flood-storage reservoir to protect the town, alongside a raised road and a new pumping station — a mix of hard defences and floodplain storage that shows the trade-off between cost, protection and impacts downstream.
Read a lag time straight off a hydrograph. If the heaviest rain falls at 12:00 and discharge peaks at 18:00, the lag time is simply \(18{:}00 - 12{:}00 = 6\) hours. Compare two catchments: a rural, wooded basin might peak at 20 cumecs with a 10-hour lag, while the same rainfall over an urbanised basin peaks at 45 cumecs with a 3-hour lag. The urban peak is \(45 \div 20 = 2.25\) times higher and arrives seven hours sooner. The analysis mark is for the why: impermeable tarmac and storm drains cut infiltration and speed surface runoff into the river, so the hydrograph becomes flashier — a short lag and a high peak — which is precisely the combination that overwhelms a channel and floods the town. State the numbers, then explain the process behind them.
CaseGlacial landscapes — the Lake District
During the last ice age, glaciers carved much of upland Britain, and glacial landforms are an optional landscape study — the Lake District is the standard choice. Ice erodes by two processes: abrasion, where rock frozen into the glacier's base scrapes and polishes the valley like sandpaper, and plucking, where meltwater freezes onto rock and rips fragments away as the glacier moves.
These processes carve a distinctive set of landforms. A corrie (or cirque) is an armchair hollow where a glacier began — Red Tarn sits in a corrie beneath Helvellyn. Where two corries erode back to back they leave a knife-edge ridge, an arête (Striding Edge); three or more meeting form a pyramidal peak. A valley glacier straightens and deepens a river valley into a steep-sided, flat-floored U-shaped valley (glacial trough), slicing off the ends of spurs as truncated spurs and leaving side valleys hanging above it as hanging valleys. When the ice melts, long, deep ribbon lakes fill the troughs — Windermere and Wastwater. Glaciers also deposit: unsorted rock called till or boulder clay, ridges of moraine, egg-shaped drumlins and out-of-place boulders called erratics.
Because the Lake District is beautiful, it draws millions of visitors, and AQA tests the resulting land-use conflicts: tourism versus farming, forestry, quarrying and water storage (reservoirs like Thirlmere and Haweswater supply distant cities). Honeypot sites suffer footpath erosion, traffic and litter. Management balances access with conservation — repairing paths, managing traffic and parking, and educating visitors — the same core tension as the rest of this paper: how to use a valued landscape without destroying it.

ExamWhat examiners want
AQA marks physical landscapes against AO1 (landform and process knowledge), AO2 (understanding how processes create landforms), AO3 (evaluating management on the 6- and 9-mark questions) and AO4 (map, photo, cross-section and hydrograph skills — a major slice of this paper).
For 'explain the formation of' questions, write the process as a sequence in the correct order, using the technical terms: for a stack, name hydraulic action and abrasion attacking a line of weakness, then crack, cave, arch, stack, stump. Ordered process chains, not a bag of loose facts, are what reach the top level. Bring in a named example (Old Harry Rocks, High Force, Red Tarn) to anchor it.
AO4 skills are guaranteed marks if you are precise: give grid references to the correct number of figures, use scale to measure real distances, describe distributions with compass directions, and read discharge and lag time straight off a hydrograph. When a question hands you a rate or a graph — a coastal retreat figure, a hydrograph — quote the numbers and manipulate them, as in the Holderness and lag-time worked examples, rather than describing them loosely. On the 'to what extent' management questions (coastal defence, flood schemes, tourism in the Lake District), always structure the costs against the benefits and finish with a supported judgement — the conclusion mark is the one most candidates leave behind.
