ECONOMIC SECTORS
100

What scale shows the entire world?

→ Global

100

What do all maps do?

→ Distort

100

Wide base indicates what?

→ Rapid growth

100

DTM measures what two things?

→ Birth rate & death rate

100

Primary sector example

→ Farming, fishing, mining

200

What scale shows cities or neighborhoods?

→ Local

200

Which projection is best for navigation?

→ Mercator

200

Narrow base indicates what?

→ Low birth rates / aging

200

ETM focuses on what?

→ Causes of death

200

Secondary sector example

→ Manufacturing

300

Why can national data hide patterns?

→ It averages data and masks regional differences

300

Which projection preserves area?

→ Peters (Gall-Peters)

300

Which country type has triangular pyramids?

→ Developing

300

Stage 2 DTM characteristics?

→ High birth rate, falling death rate

300

Tertiary sector example

→ Services

400

Give one example best studied at regional scale

→ climate, migration patterns, economic differences

400

Which 4 things can maps distort?

→ Shape, size, distance, direction

400

Problem of aging population?

→ Strain on healthcare/pensions

400

Stage 4 ETM characteristics?

→ Degenerative diseases dominate

400

Quaternary sector example

→ Technology/research

500

Explain why scale matters in analyzing population

→ Patterns vary depending on level of analysis

500

Why does Mercator exaggerate size near poles?

→ Because of cylindrical projection stretching

500

Why might a pyramid suddenly change shape?

→ War, migration, policy, disease

500

Explain how DTM and ETM are connected

→ Development affects both population growth and disease patterns

500

Why do developed countries have more tertiary jobs?

→ Shift from manufacturing to services (post-industrial economy)
