Economic activities are sorted by what they do to a product. Take it from nature and it is primary, change it and it is secondary, serve someone with it and it is tertiary.
This lesson is part of economic activities and resources. Once you can classify, the next step is explaining location factors.
How do I classify an activity?
Ask one question: does this activity take, change or serve?
| Activity does this | Category | Examples |
|---|---|---|
| Takes a product from nature | Primary | Farming, fishing, mining, forestry |
| Changes materials into products | Secondary | Manufacturing, construction, food processing |
| Provides a service | Tertiary | Transport, banking, retail, teaching, tourism |
Read the verb in the question, not the product name. The verb tells you what the activity does.
Worked example: one product, three categories
Follow rubber from tree to customer in a fictional chain.
- A smallholder taps latex from rubber trees. The activity takes from nature, so it is primary.
- A factory turns the latex into gloves. The activity changes the material, so it is secondary.
- A shipping company carries the gloves to a hospital abroad. The activity serves, so it is tertiary.
The same rubber passes through all three. The category follows the activity at each step, which is why “rubber is primary” is not a full answer.
The mistake that costs marks
The common slip is to classify by the product. A student writes “palm oil is primary” because oil palms are grown on plantations.
Growing palm fruit is primary. Crushing the fruit at a mill to extract oil is secondary. Both happen in the same place, yet they are different activities.
| Answer | Verdict |
|---|---|
| “Palm oil production is primary” | Too broad: which step? |
| “Growing oil palm is primary, milling the fruit is secondary” | Correct, each step classified by what it does |
The fix: name the activity as a verb phrase first, then classify it.
Check yourself
Classify each and give the reason: (a) a farmer harvesting paddy, (b) a mill turning paddy into rice, (c) a lorry driver delivering rice to shops, (d) a miner digging tin ore.
Answer
(a) Primary: takes paddy from the land. (b) Secondary: changes paddy into rice. (c) Tertiary: provides a transport service. (d) Primary: takes ore directly from the ground.
What to study next
Continue with explaining location factors to say why each activity sits where it does. Then test yourself on the economic activities practice set.
