Landforms from Contours and Settlement Patterns (ICSE Class 8 Geography)

Updated 17 October 2026 · Draft, not yet fact-checked

A hill is shown by closed contours with rising values towards a small summit, and a plateau by crowded contours at its edges and an empty wide top. A ridge is a long narrow high area; a saddle, col, gap and pass are lower points on or through it. Settlements are temporary or permanent, and permanent ones may be nucleated (clustered), dispersed (scattered) or linear (in a line).

Understand Hills, Plateaus, Ridges, Passes and Settlement Patterns

1. Hill and plateau. A *hill* has roughly circular contours, one inside another, with values rising to a small summit marked by the innermost contour or a spot height. Closely spaced contours make a steep hill; widely spaced ones a gentle hill. A *plateau* is a tableland: the contours crowd at the edges (steep sides) and then there is a broad area with few or no contours (flat top). A quick test: many contours climbing to a small top is a hill; contours bunched at the rim with a wide empty centre is a plateau.

2. Valley and spur. A valley is shown by V-shaped contours that point towards higher ground, and a river often lies along it. A spur is the opposite: the V points towards lower ground.

3. Ridge. A ridge is a long, narrow stretch of high ground with steep sides, drawn as elongated oval contours with values rising towards the central line. It may have more than one summit.

4. Lower points on a ridge. A *saddle* is a broad, gentle dip between two summits, like a horse saddle. A *col* is a narrower, sharper dip, smaller and steeper than a saddle. A *gap* is a steep-sided opening through a ridge, often cut by a river. A *pass* is any gap, col or saddle that gives a route across a range; roads and railways use passes. Examples named in the chapter are the Khyber Pass and Nathu La. On a toposheet, look for the place where the contours of two higher areas come close but do not join, often with a road or track crossing there.

5. Settlements. A settlement is any place where people live. *Temporary* settlements are used for a short period, for example by herders who move with their animals or by people practising shifting cultivation. *Permanent* settlements have lasting houses and are occupied throughout the year: villages, towns and cities.

6. Patterns of permanent settlements.

*Nucleated (clustered):* houses are crowded round a centre such as a temple, well, market or crossroads. Common on fertile plains with a good water supply and where people want safety in numbers.
*Dispersed (scattered):* houses are spread out, separated by fields, forest or rough land. Common in hilly, forested or dry areas and where farms are large.
*Linear:* houses form a line along a road, railway, river, canal, coast or valley floor.

Factors: relief, water supply, soil, transport routes, climate and security.

7. Interpreting a toposheet. Read the margin first (sheet number, scale, contour interval, signs). On a 1:50,000 sheet, 1 cm = 0.5 km and a 2 cm grid square is 1 km by 1 km. Then study relief, drainage (blue; water flows from higher to lower contours), vegetation and land use, settlements and communications. Link features: villages on gentle slopes near water, roads through gaps.

How to answer Hills, Plateaus, Ridges, Passes and Settlement Patterns questions

To identify a landform, look at the contour shape first.

1Check the values: do they rise or fall towards the centre?
2Check spacing: close at the edges means steep sides.
3For settlements, count and place the house symbols: crowded, scattered or in a line.
4Always give the reason a pattern forms: relief, water, roads or farm size.

Hills, Plateaus, Ridges, Passes and Settlement Patterns in real life

The idea, met in an everyday situation. Answer the question in your own words, then compare with the model answer. The one-line hook is what to remember.

Planning a village shop

Suppose a shopkeeper must choose a spot to serve three hamlets. Hamlet P has houses along one road; hamlet Q has houses clustered round a well; hamlet R has farms spread over a hillside.

Name each pattern and say where one shop would reach the most customers on foot.

Try it first, then show the solutionSolution

P is a linear pattern, Q is nucleated and R is dispersed.
Customers in Q live within a few steps of each other, so a shop beside the well serves most of them.
In R, houses are far apart, so a shop reaches fewer people.

Answer: P linear, Q nucleated, R dispersed; the shop beside Q's well serves most customers.

Memory hook: Cluster, line, scatter: count how far people must walk.

Tricks to remember Hills, Plateaus, Ridges, Passes and Settlement Patterns

Short memory aids. Say each one aloud once, then use it on a question the same day.

Hill small, plateau wide
A hill finishes in a small top; a plateau has a wide empty top inside crowded edge contours.
Use it when: Hill or plateau questions.
Saddle soft, col sharp
Saddle is the gentle horse-seat dip; col is the sharper, narrower dip.
Use it when: Distinguishing the two.
Pass = path
A pass is a gap, col or saddle that people use as a path across mountains.
Use it when: Definitions.

Hills, Plateaus, Ridges, Passes and Settlement Patterns: solved examples

Ordered from board level to HOTS. Try each one before you open the solution.

Example 1: Hill or plateau · 2 marks · Short answerBoard level

Contours on a sheet are crowded close together along the edge of a block of land, while the centre has a wide area with only one contour line. Name the landform and give a reason.

Try it first, then show the solutionSolution

Closely spaced contours at the edge show steep sides.
A wide space with few contours inside shows a flat top.
This is a plateau.

Answer: A plateau: steep sides and a broad flat top.

Example 2: Saddle and col · 2 marks · Short answerBoard level

Distinguish between a saddle and a col.

Try it first, then show the solutionSolution

A saddle is a broad, gentle depression between two summits.
A col is a narrower, sharper depression between summits and is smaller and steeper.

Answer: Saddle is broad and gentle; col is narrow and sharp.

Example 3: Why a pass matters · 3 marks · Short answerHarder board level

What is a pass? Explain why roads and railways are built through passes and name one example.

Try it first, then show the solutionSolution

A pass is a gap, col or saddle in a mountain range that provides a route across it.
Elsewhere the mountain wall is high and steep, so building through the lowest point saves height and cost.
Example: Nathu La in Sikkim (the Khyber Pass is another).

Answer: A pass is a low route across a range; roads use it to avoid steep climbs. Example: Nathu La.

Example 4: Settlement pattern in a valley · 4 marks · Long answerHarder board level

A toposheet shows 14 houses placed one after another along a road in a narrow valley, each about 100 m from the next. (a) Name the pattern. (b) Give two reasons for it. (c) What would the symbols look like if the pattern were nucleated?

Try it first, then show the solutionSolution

(a) Linear settlement.
(b) The road gives access to markets and transport; the narrow valley floor is the only flat, level land with water near the stream.
(c) Nucleated: the same houses would be crowded together in a small area round a centre such as a well or crossroads.

Answer: (a) Linear (b) Road access and narrow flat valley floor (c) Crowded together round a centre.

Example 5: Reading a sheet · 4 marks · Long answerHOTS / competency

On a 1:50,000 toposheet a village lies on a gentle slope within 1.5 cm of a perennial stream, and a road passes through a gap between two hills. (a) Find the ground distance from the village to the stream. (b) Explain why the village is sited there. (c) Why does the road use the gap?

Try it first, then show the solutionSolution

(a) 1.5 cm x 0.5 km = 0.75 km = 750 m.
(b) A gentle slope gives flat land for houses and fields, and the stream gives water for drinking and irrigation all year.
(c) The gap is the lowest point between the hills, so the road avoids a steep climb and keeps the gradient small.

Answer: (a) 0.75 km (b) Flat land and water supply (c) Low route through the hills.

Where students lose marks in Hills, Plateaus, Ridges, Passes and Settlement Patterns

The slips examiners see most often, and what to write instead.

Mistake: Calling every circular contour a plateau
The values rising to a small top are ignored.
Do this: Check the spacing: a plateau has a wide, almost empty top.
Usually costs: 1 to 2 marks.
Mistake: Mixing up saddle, col and gap
The three are described with the same words.
Do this: Saddle: broad dip; col: narrow dip; gap: opening through a ridge; pass: the route.
Usually costs: 1 mark.
Mistake: Giving no reason for a pattern
The pattern is named but the cause is missing.
Do this: Add relief, water supply, roads or farm size.
Usually costs: 1 mark.
Mistake: Wrong scale conversion on a 1:50,000 sheet
Candidates treat 1 cm as 1 km.
Wrong working
Distance = 1.5 cm = 1.5 km
Right working
Distance = 1.5 x 0.5 = 0.75 km
Do this: Remember 1 cm = 0.5 km.
Usually costs: 1 to 2 marks.

Exam tips

Sketch the contour shape in the margin before naming the landform.
Give a reason with every identification: "because the contours are close at the edges".
Use the exact words nucleated, dispersed and linear; "clustered" and "scattered" are acceptable alternatives only if the term is also written.
For a pass, mention that the road follows the low point between two higher areas.

Q8 · 3 marks · Short answerHarder board level
Give three factors that influence the pattern of settlements in an area and explain one of them with an example.
Hint
Relief, water, transport...
Answer
Relief, water supply and transport routes (also soil and climate). Example: a river or a road attracts houses along it, producing a linear pattern; or fertile plains with a well produce a nucleated village.
Q9 · 4 marks · Long answerHOTS / competency
A village sits in a hot, dry region where water is available only at a few wells far apart. Predict and justify the settlement pattern, then say how it would change if a canal were dug through the region.
Hint
Water decides where people can live.
Answer
People would cluster round the wells, so the pattern is nucleated near each well, with large empty gaps between clusters. Once a canal is dug, houses would spread out along its banks, producing a more linear pattern, because water would now be available along its length.

Hills, Plateaus, Ridges, Passes and Settlement Patterns: frequently asked questions

How can I tell a hill from a plateau on a map?

A hill has circular contours rising to a small summit; a plateau has crowded contours at the edges and a wide, empty, flat top.

What colour shows settlements on a toposheet?

Red is used for permanent settlements, roads and buildings.

Is a gap the same as a pass?

A gap is an opening through a ridge; it becomes a pass when it provides a route across the range.

Are temporary settlements ever permanent later?

Sometimes, if people decide to stay, but by definition a temporary settlement is used only for a short time.
