Scattered Rubbish is a term used to describe the accumulation of waste materials that have been left in an area. LITTER and DEBRIS are two words that can be used to describe this type of rubbish. LITTER is defined as small pieces of trash or garbage that have been carelessly discarded in an area, while DEBRIS is defined as the remains of something that has been destroyed or broken up. Both LITTER and DEBRIS can be found scattered in public places, parks, and other outdoor areas.
