White Ridges on Mars
These white ridges on Mars, captured by the Mars Reconnaissance Orbiter, are a puzzle. One theory suggests they formed when water flowed through underground cracks, altering and hardening the surrounding rock. Over millions of years, winds eroded the softer surface material, leaving the resistant white ridges exposed. Such features hint at Mars' watery past.
