Chapter Overview
Weather is day-to-day atmospheric condition; climate is average pattern over many years. Animals adapt to climate — polar bear's fur, camel's hump, tropical rainforest diversity.
Weather vs Climate
- Weather: temperature, humidity, rainfall, wind on a given day
- Climate: long-term pattern (desert, tropical, polar)
- Meteorologists study weather; climate data spans decades
Adaptations
- Polar region: thick fur, white colour, layer of fat (seal, polar bear)
- Desert: less sweat, long eyelashes, nostrils close (camel)
- Rainforest: loud calls, bright colours, climbing (monkeys, toucans)
Migration
- Birds fly to warmer regions in winter
- Monarch butterflies migrate thousands of km
- Escape harsh climate, find food

Adaptation
How is polar bear adapted to cold?
- 1Thick white fur camouflages and insulates
- 2Fat layer under skin
- 3Wide paws for snow
Answer
Insulation and camouflage in snow
Climate zone
Name features of tropical rainforest climate.
- 1High temperature and rainfall year-round
- 2Dense vegetation
- 3Rich biodiversity
Answer
Hot, wet, diverse ecosystem
Key Points to Remember
- ✓ Penguins adapted to Antarctic cold
- ✓ Elephants adapted to tropical heat
- ✓ Weather can change quickly; climate cannot
Exam Tips
- • Distinguish weather and climate with examples
- • Give three adaptations of desert animals
- • Why do birds migrate?
