Land and Sea Breezes

Figure from experiment 25 from Earth Science with Vernier

Introduction

Land breezes and sea breezes refer to winds that often occur near an ocean or lake. Land breezes blow from the land to the water while sea breezes blow from the water to the land. Both of these breezes are caused by uneven heating of the Earth’s surface. In this experiment, you will recreate the conditions under which these breezes form and study their causes.

In Part I of this experiment, you will expose sand and water to a light source representing the sun. You will monitor the temperature of the sand and the water and compare their warming behaviors. In Part II, you will monitor the temperatures as warm sand and water cool. This simulates the situation when the sun goes down in the evening. You will then apply your results to local weather patterns.

Objectives

In this experiment, you will

  • Use Temperature Probes to measure the temperature of land and water.
  • Calculate temperature changes.
  • Apply your results to local weather patterns.
  • Predict the occurrence of land and sea breezes.

Sensors and Equipment

This experiment requires each of the following Vernier sensors and equipment (unless otherwise noted):

Additional Requirements
