Question

Explain which mode of heat transfer causes sea breezes and land breezes.

Answer 1

Sea breezes and land breezes are caused by the mode of heat transfer called convection.

1. Sea Breeze (Daytime):

   • During the day, the land heats up faster than the sea due to the difference in heat capacity.
   • The warm air over the land rises, creating a low-pressure area.
   • Cooler, denser air from the sea moves in to replace it, creating a sea breeze from the sea to the land.

2. Land Breeze (Nighttime):

   • At night, the land cools down faster than the sea.
   • The warm air over the sea rises, creating a low-pressure area.
   • Cooler air from the land moves toward the sea, forming a land breeze from the land to the sea.
