Etymology
Kieselguhr comes from German parts kiesel ('pebble') and guhr ('earth'), and it names a light, sandy powder made of the tiny glass shells of dead water plants. So think 'pebble-earth' to remember it's a lightweight material full of tiny holes that is used as a filter or to absorb liquids.
