Each year during the third week in November, the National Geographic and other organizations help celebrate Geography Awareness Week. The focus is to help raise awareness of the importance of geography education. They have a web site called My Wonderful World which provides a weeklong guide of activities and ideas for learning and experiencing education. Of course, included in the activities are some Google Earth files. For example, here is a tour of cultures 
which is based on a National Geographic publication called Glimpse. And, here is a tour of Global Hot Spots having to do with change in environments, cultures, politics, climate, or population. And there is a tour of geographers on the job around the world.
Google has highlighted Geography Awareness Week as well and links to these same files.
