Can rocks move? Well on mars small rocks called clasts seem to move a lot. Scientist were stunned by this phenomenon. Jon Pelletier a geologist has been trying to find out how these scattered clasts "move". It seemed to be that the wind blew the rocks forward. But since the planet mars has a skinny atmosphere that would be harder to do. So what scientist found out was that the rocks go through a system called the "tidy arrangement". What scientist think what happens is that the wind from the windy planet picks up sand from the planet and places it behind the rock. Making small dunes behind the rock. Which also creates a hole in front of the rock. So as long as the wind keeps blowing in Mars the clasts will keep moving.
