Accretion
The interaction of earth-orbiting and Sun-orbiting planetesimals (very large chunks of rocks like asteroids) early in the history of the Solar System led to their breakup. The Moon condensed from this debris.
cinders
Microglial cells are the primary cells responsible for removing debris from the CNS. These cells act as the resident immune cells of the CNS and are constantly surveying the brain for any abnormal or harmful substances. Upon detection, microglia engulf and remove the debris through a process called phagocytosis.

NASA recently released a photo of the spreading debris from a collision in the asteroid belt.
Scientists say that Pluto is not a planet because, like Ceres in the asteroid belt, it has failed to clear its neighborhood of planetesimals and other debris.
Such debris is usually called soot
The interaction of earth-orbiting and Sun-orbiting planetesimals (very large chunks of rocks like asteroids) early in the history of the Solar System led to their breakup. The Moon condensed from this debris.
If you mean come into existence then ; about 4.5 billion years ago two planetesimals (the bigger one the proto Earth) collided. This gave the Earth its spin (day-night) & the debris field (some of it anyway) formed the moon.
Unsorted rocky debris that is formed by a melting glacier is called moraine. There are many different types of moraine depending on where the debris is found and deposited.
Gravel.
Regolith
Debris
Objects inside a tornado are called debris.
Macrophages are "big eaters" and are a type of white blood cell that engulf and digest cellular debris, foreign substances, microbes, and cancer cells in a process called phagocytosis.
Radioactive wastes
