Coastal Wind

In the picture

1. 1The low sun: it heats land and sea unevenly.
2. 2Air above sunlit rocks: it warms, rises, and leaves lower pressure near the ground.
3. 3Air above the sea: it stays cooler and denser, with higher pressure that pushes toward land.
4. 4Bending trees and leaves: they show air moving from higher pressure to lower pressure across the shore.

Examples

• A sea breeze on a sunny beach
• A draft through a window gap on a cold day

Quiz: Coastal Wind (Age 16)

1. 1

   According to the card, what is wind?

   • Air moving from cooler regions to warmer regions
   • Air moving from higher pressure to lower pressure
   • Air moving from lower pressure to higher pressure
2. 2

   What creates the pressure differences that cause wind?

   • Differences in ocean salinity
   • Uneven heating of land and sea by the sun
   • Earth’s rotation on its axis
3. 3

   In the coastal example, what happens to air above sunlit rocks?

   • It cools, sinks, and creates higher pressure near the ground
   • It stays at the same temperature and does not move
   • It warms, rises, and leaves lower pressure near the ground
