Social Science — CBSE Class 10 board question

| Basis | Primary Sector | Secondary Sector |
|-------|----------------|-----------------|
| Meaning | Activities that directly use natural resources to produce goods | Activities that convert natural products into manufactured goods through industrial processes |
| Nature | Depends on natural factors like rainfall, sunshine, climate | Requires manufacturing — in factories, workshops, or at home |
| Also called | Agriculture and related sector | Industrial sector |
| Examples | Farming, dairy, fishing, forestry, mining | Spinning yarn from cotton, making sugar from sugarcane, converting earth into bricks |

The primary sector forms the base for all other sectors, as it provides raw materials that the secondary sector then processes into finished goods.

• Examiners look for: a clear definition of each sector, the key difference (natural vs. manufactured), and at least one example each.
• A table format is ideal here — it shows comparison clearly and saves words.
• The phrase "forms the base" is textbook language; using it shows you've read the source.
• Don't mix in the tertiary sector unless specifically asked — it wastes space and marks aren't given for unrequested content.
