6. sea breeze – a wind that blows from the sea toward the land

7. sea breeze – a wind that blows from the sea toward the land

8. land breeze – a wind that blows from the land toward the sea

9. sea breezes vs. land breezes

10. Coriolis effect – no matter which way the wind blows, it will always pull toward the right in the northern hemisphere, and to the left in southern hemisphere.
