Local winds along the coastal region areas create alternating land breezes and sea breezes during the course of a day. This is a repeating pattern that happens daily worldwide, but only along shorelines. This table shows possible explanations for the breezes. Possible Explanations for Daily Breezes

Explanation

Change

Air Over Land

Air Over Water

1

Land heats faster than water during the day

Expands and rises

Denser, causing a low pressure area

2

Water cools faster than land during the night

Expands and rises

Denser, causing a low pressure area

3

Land heats faster than water during the day

Contracts and sinks

Cooler and less dense, causing a high pressure area

4

Land cools faster than water during the night

Contracts and sinks

Warmer, causing a low pressure area
