Rocks known to be able to float on water
WebSome sediments formed from glacial movement can be extremely fine, and are known as ‘glacial flour’. This material can stay floating in the water for a very long time, and can be easily transported by ocean currents far from land into deep sea. Glaciers and ice sheets can also carry other bigger sediments, which are entrained in the ice flow.
