Compare rates
Land changes four degrees per model step while sea changes one. These rates are exaggerated.
Sea Breeze Coast
Compare daytime warming and nighttime cooling, then place a surface wind arrow along a coast.
Grades 3–5 · Earth Science
Your goal
Model day conditions until land and sea differ by 3 degrees. Place the near-surface wind arrow toward the warmer surface.
Reduced motion is on. The controls still update the scene.
0 day steps. Land is 20 degrees and sea is 20 degrees. Equal temperatures give no thermal breeze in this model.
Both surfaces begin at 20 degrees when you choose a period. Each illustrative day step warms land by four degrees and sea by one; night steps cool them at those rates. Temperature differences drive a small circulation as warm air rises and replacement air moves near the surface. These exaggerated rates isolate the concept. Pressure systems, coastline shape, seasons and other winds are omitted.

Learn with Sea Breeze Coast
Sea Breeze Coast helps elementary students connect temperature differences with coastal air movement. Choose daytime or nighttime conditions and advance the model one heating step at a time. Land changes temperature faster than the sea, creating a growing contrast. Students then place a near-surface wind arrow from the cooler surface toward the warmer surface. The scene also sketches rising warm air and the return flow above. Goals vary the period and contrast, supporting comparisons of daytime sea breezes and nighttime land breezes.
What to look for
Find the warmer side
During daytime land becomes warmer. During nighttime land cools faster than sea.
Place surface wind
Move the arrow from the cooler side toward the warmer side where air rises.
For teachers and curious learners
Connect differential heating of land and water with the direction of a thermal coastal breeze. Ask students to predict what will happen, change one setting, and explain what they observe. Learn gives a starting point. Practice and Challenge offer new goals with the same scene.
Both surfaces reset to twenty degrees. Exaggerated constant heating or cooling rates isolate differential heating. Real pressure systems, coastline geometry, seasonal conditions and other winds are omitted.
