Concept
Debris
Summary
Debris (UKˈdɛbriː,_ˈdeɪbriː, USdəˈbriː) is rubble, wreckage, ruins, litter and discarded garbage/refuse/trash, scattered remains of something destroyed, or, as in geology, large rock fragments left by a melting glacier, etc. Depending on context, debris can refer to a number of different things. The first apparent use of the French word in English is in a 1701 description of the army of Prince Rupert upon its retreat from a battle with the army of Oliver Cromwell, in England.
In disaster scenarios, tornadoes leave behind large pieces of houses and mass destruction overall. This debris also flies around the tornado itself when it is in progress. The tornado's winds capture debris it kicks up in its wind orbit, and spins it inside its vortex. The tornado's wind radius is larger than the funnel itself. Tsunamis and hurricanes also bring large amounts of debris, such as Hurricane Katrina in 2005 and Hurricane Sandy in 2012. Earthquakes rock cities to rubble debris.
In geology, debris usually applies to the remains of geological activity including landslides, volcanic explosions, avalanches, mudflows or Glacial lake outburst floods (Jökulhlaups) and moraine, lahars, and lava eruptions. Geological debris sometimes moves in a stream called a debris flow. When it accumulates at the base of hillsides, it can be called "talus" or "scree".
In mining, debris called attle usually consists of rock fragments which contain little or no ore.
marine debris
Marine debris applies to floating garbage such as bottles, cans, styrofoam, cruise ship waste, offshore oil and gas exploration and production facilities pollution, and fishing paraphernalia from professional and recreational boaters. Marine debris is also called litter or flotsam and jetsam. Objects that can constitute marine debris include used automobile tires, detergent bottles, medical wastes, discarded fishing line and nets, soda cans, and bilge waste solids.
In addition to being unsightly, it can pose a serious threat to marine life, boats, swimmers, divers, and others.
