The term MOVING ICE can be summarized by the crossword solution FLOE, which is a four-letter word. A FLOE is a large sheet of floating ice that moves across the surface of a body of water, such as an ocean or lake. Floes are typically formed when pieces of ice break off from larger sheets of ice and drift away. They can also form when ice melts and refreezes in a different location. Floes can be dangerous for ships and other vessels, as they can cause collisions or damage to the hulls of boats.
