## Caption

The different sand colors in the Sahara Desert come from variations in mineral composition and weathering history. Quartz rich sand appears pale or white, iron oxides stain grains red or orange, and darker tones come from volcanic or heavy minerals like magnetite. Over millions of years, wind erosion breaks rocks from different source regions and mixes them unevenly. Chemical oxidation under intense heat further alters colors. These variations reveal past environments, rock origins, and the geochemical processes shaping the desert landscape.
