Mastery Evidence

✓ Explain that the Sun heats Earth's surface unevenly
✓ State that warm air rises and cooler air moves in to replace it
✓ Define this air movement as wind

Assessment Prompt

Can your child explain why wind blows — that the Sun warms some areas more than others, warm air floats upward, and cooler air rushes in to fill the gap?
