Why do desert rocks have fantastic shapes?

Desert erosion is different from any other type of erosion because there is hardly any water involved. Wind is the main force. It picks up sand grains and hurls them against exposed rocks, wearing them away into fantastic shapes and polishing them to shiny surfaces. The rock fragments that are blasted off become more sand. | | The motion of sand dunes in the wind. Sand particles can polish and shape rock |
