the moon
We believe that the proto-Earth, very early in the formation of our solar system, probably collided with another planet, one that might have been as large as Mars. The collision probably entirely re-formed the resultant Earth, and that the heavy metallic cores of both planets merged. Debris blasted into space by the collision probably coalesced to form the Moon.
The three types of materials found in the planetary rings that collided with the Earth are silicate rock, ice, and organic compounds. These materials were present in the form of dust, debris, and small particles that accumulated in the ring system around the protoplanet. The collision of these materials with the Earth contributed to the formation and composition of our planet.
Ashfall is the common name given to the ash rocks and other debris that is ejected from a volcano during an eruption.
The current thinking is that during the early Solar System, in what is called the Bombardment Period, a protoplanet collided with the young Earth and knocked off a big chunk (about 1/80th of the planet's mass). For a while, the debris of this collision circled Earth with Saturn-like rings, but eventually these consolidated into the Moon.
We believe that shortly after the solar system formed, our planet Earth probably collided with another planet that was much smaller, probably smaller than Mars. The proto-Earth and the other body merged, and the debris from the collision probably formed the Moon. Since then, we're not aware of any collisions.
the moon
The giant impact theory that the moon formed when Earth collided with another object named Theia that was roughly the size of Mars. The debris ejected into space later came together to form the moon.
"Ejected debris" the the solid material shot into the air by an erupting volcano (as opposed to the gasses ejected by the same eruption).

Collision of the debris is the term that is given to the collision of the stones.

Space debris is anything man-made that has been launched into space, but no longer has any function. Most debris is from parts of satellites/stations that have been ejected or that have fallen away.

Earth's moon is believed to have formed when Earth collided with a Mars-sized planetoid soon after it formed. Debris from the collision formed a ring around Earth and coalesced into the moon. Scientists still disagree about the origins of Mars' moons Phobos and Deimos. The most prevalent hypothesis is that they are captured asteroids.
