2. 1. Wind is caused by the uneven heating of the Earth
2. These temperature differences create high pressure
and low pressure areas
3. Wind – the movement of air from an area of high to
low pressure
How does
wind form?:

3. 1. Tilt in orbit around the sun
2. Curved surface of the Earth
3. Equator receives the most radiation, poles
receive the least
What Causes
Temperature
Differences?:

4. 1. Warm air is less dense than cold air so it rises
2. Cold air sinks and moves along the Earth’s
surface
Density of
Air:

5. • Concept: Land heats up and cools down faster
than water
Local
Winds:

6. • Wind blowing from land to sea during the night
• Caused by:
• Water cools off slower so it warms the air above it
causing it to rise
• Air above land moves in to replace it
Land
Breeze:

7. • Wind blowing from sea to land during the day
• Caused by:
• Land warmed faster by the sun
• Air warmed above land rises
• Air above water moves in to replace it
