Slope Streaks in Arabia Terra

Slope Streaks in Arabia Terra

Slope Streaks in Arabia Terra
This image shows numerous light-toned streaks that seem to flow along the ground surface. These streaks form when dust and possibly sand-sized particles avalanche downhill.

Tracing these slope streaks back to their apex, or narrow, triangular-shaped end reveals that these avalanches started within the sun-lit slopes at the tops of hills and ridges. This suggests that formation of these slope streaks may have been helped by the sun warming the ground surface and destabilizing small accumulations of dust and sand.
