The theory that the outer layer of the Earth (the lithosphere) is broken in several plates, and these plates move relative to one another, causing the major topographic features of Earth (e.g.

While most properties are based on the number of protons in an element, isotopes can have subtle changes between them, including temperature fractionation and Wikimedia Commons' src=" alt="Two protons and two neutrons leave the nucleus." width="212" height="144" srcset=" sizes="(max-width: 212px) 85vw, 212px"/CC BY-SA 4.0], via Wikimedia Commons' src=" alt="Simplified Periodic Table of the Elements" width="477" height="254" srcset=" sizes="(max-width: 477px) 85vw, 477px"/An atom that has different number of neutrons but the same number of protons.

A stoney and/or metallic object from our solar system which was never incorporated into a planet and has fallen onto Earth.

The result leaves two different effects: either an electron jumps in to fill the missing spot of the departed electron (emitting an X-ray), or in the Auger process, another electron is released, changing the atom into an ion An atom that has different number of neutrons but the same number of protons.
