What begins with Q? QuikSCAT, quakes, and quicksand. The quirky quixotic quartz pebbles in this lake with a queer shape!
On November 29, 2004, the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA’s Terra satellite acquired this image of Lonar Crater in India. Shocked quartz—minerals with an unusual structure that can only form under intense pressure—offers a clue that the lake was formed by a large meteorite.
