Sandbending

Sandbending is a lower classification of earthbending that the Dwellers in the Si Wong Desert invented. They mainly use it to propel their sandsailers which make them travel faster. When Toph Beifong made the Republic City Police Force she started by making them sandbenders. One of the most notable things about sandbending is hat Avatar Genji himself has taken a liking to using it.

Since, their style of earthbending is more related to airbending and waterbening(due to the fact that sand is sediments), earthbenders are expected to easily master sandbending. Although, it is difficult for an average earthbender to to preform this because of the sands loose shifty nature of the sand. Sanbending can be use to wrap around things to keep them concealed because sandbenders can make the sand thicker and keep things in check. A lower classification of sandbending would be glassbending though nothing about glassbending is known yet.
