What does the term 'debris' refer to?

The term 'debris' commonly refers to the scattered pieces of waste or remains that are left behind after an object has been damaged or destroyed. This is particularly evident in contexts such as natural disasters, where debris can consist of fallen trees, broken buildings, and other remnants that have been discarded or fragmented. The correct answer emphasizes that debris is made up of materials that have been damaged or destroyed, highlighting the non-organized, chaotic nature of such remnants.

In contrast, the other options do not accurately capture the essence of what debris represents. New substances created refer to materials that have undergone chemical changes, while undisturbed remnants imply a state of preservation. Organized structures that support ecosystems suggest a level of order and functionality that debris simply does not possess. Thus, the correct answer clearly identifies debris as the remains of destroyed materials.
