What Causes Land And Sea Breezes?

key notes :

Definition of Land and Sea Breezes:

• A land breeze is wind blowing from the land to the sea during the night.
• A sea breeze is wind blowing from the sea to the land during the day.

Why Do They Happen?

• The land and water heat up and cool down at different rates.
• Land heats up and cools down faster than water.

Sea Breeze (Daytime):

• During the day, the land becomes hotter than the sea.
• Warm air over the land rises, creating low pressure.
• Cool air from the sea moves in to replace the rising warm air. This is called a sea breeze.

Land Breeze (Nighttime):

• At night, the land cools down faster than the sea.
• The air over the sea is warmer and rises, creating low pressure over the sea.
• Cool air from the land moves toward the sea to replace the rising warm air. This is called a land breeze.

Role of Air Pressure:

• Warm air rises because it is lighter, creating low pressure.
• Cool air sinks because it is heavier, creating high pressure.
• The difference in air pressure causes the movement of air, which we feel as wind.

Examples in Daily Life:

• Sea breezes make coastal areas cooler during the day.
• Land breezes are more common during calm nights.

Fun Fact:

• Sailors in the past relied on sea breezes to navigate their ships along the coast.
