 Land & Sea Breezes Worksheet-Teacher guided
   –   Draw in the direction of air flow
   –   Label the land & sea breeze
   –   Indicate the areas of high and low pressure
 Think about:
   –   Why do clouds form over land during the day?
   –   Why do the clouds disappear at night?
   –   Why does the ocean temperature remain constant?
