Must know

1Pollution can affect air, water, soil, and sound environments, and each type has characteristic sources and pollutants.
2A pollutant is any harmful substance or factor that disturbs normal environmental quality.
3Vehicles, industry, sewage, chemicals, plastics, and noise sources are typical examples, but answers should classify...
4The same source can affect more than one type, but the answer still needs clear classification.

Formula / process

1First name the type, then attach the relevant source or pollutant.
2Pollution can affect air, water, soil, and sound environments, and each type has characteristic sources and pollutants.
3After the definition, add one sentence on persistence or safe handling.
4Biodegradable wastes break down naturally by microorganisms, while non-biodegradable wastes remain for long periods.

Exam traps

1Students often list sources randomly without linking them to the pollution type.
2First name the type, then attach the relevant source or pollutant.
3Did each source in your answer belong to the type you named?
4Students may define the two waste types but forget to mention their practical consequences.

Answer frame

Start with the exact keyword or formula before adding explanation.
Use one example, diagram cue, observation, or substitution to support the answer.
For 3 marks: definition, reason, and one supporting point.
For 5 marks: setup, method/process, example, conclusion, and final check.

Exam strategy

Write to the mark pattern

3 focus areas

Practice written answers Chapter test

Likely prompts

1Labelled diagram questions with function of each part.
2Process-flow questions: sequence, role, and significance.
3Difference-between and reason-based prompts using exact biological terms.

Keywords to include

1Types, Sources, and Major Pollutants
2Meaning
3One-minute summary
4Air
5Water
6Soil

Avoid these traps

1Students often list sources randomly without linking them to the pollution type.
2First name the type, then attach the relevant source or pollutant.
3Type, source, and pollutant should stay grouped.
4Classification helps the answer stay organised.

Answer frame by marks

3 marks

Name the structure/process, give its function, and add one labelled or sequence point.

5 marks

Start with the main process, write the sequence, include key terms, and end with significance.

Pollution classification model

Use the labels to connect each part of pollution classification to the Grade 10 Biology idea.

Air

Atmospheric pollution type.

Water

Aquatic pollution type.

Check: Type, source, and pollutant should stay grouped.

3D visual of biodegradable and non-biodegradable waste sorting

DiagramBiodegradable and Non-biodegradable Wastes

Waste comparison model

Use the labels to connect each part of waste comparison to the Grade 10 Biology idea.

Biodegradable

Breaks down naturally.

Non-biodegradable

Persists for long periods.

Check: Definition plus environmental effect makes a complete answer.

3D visual of pollution effects and control measures

DiagramEffects and Control of Pollution

Pollution effect-control map model

Use the labels to connect each part of pollution effect-control map to the Grade 10 Biology idea.

Pollutant

Source of harm.

Health

Human impact.

Check: Strong answers pair the effect with the control.

FlowTypes, Sources, and Major Pollutants

Classifying a pollution example flow

Follow this sequence when writing or checking an answer on classifying a pollution example.

Name the pollution type

Air, water, soil, or noise.

State source

What is causing it?

Check: Classification helps the answer stay organised.
