True or False: Sand dunes are one of the most stable features on the Earth's surface.

Yikes! You must have never seen sand dunes.

The sand blows all over and a dune never looks the same from one year to the next.

I'll never forget the dunes in a northern Michigan community on Lake Michigan. Several of the cottages were covered with sand and the others were beginning to be encased in sand.

False: Sand dunes are not one of the most stable features on the Earth's surface. They are constantly changing and shifting due to wind and other environmental factors. To determine the stability of sand dunes, we need to consider their formation, movement, and interaction with the surroundings.
