Sand Dune

Real World Example

Imagine trying to organize the clutter on your desk, but no matter how much you tidy up, small items keep piling up in the same spot. This is similar to how wind moves grains of sand across a desert or beach, depositing them in a mound called a sand dune. Just like your desk collects clutter because of certain habits or tendencies, a sand dune forms because the wind consistently drops sand in the same location, building up over time into a noticeable mound.
