atmosphere: An envelope of gas surrounding the Earth, another planet, or the Moon.
cosmic rays: Very high-energy particles, mainly protons, that hit the Earth from all directions. These particles originate outside the solar system. They correspond to the nucleus of an atom. They travel through space at high speeds (often close to the speed of light).
charge: Physical property responsible for electric force. It can be negative or positive.
electricity: A flow of charge, usually resulting from the movement of negatively charged particles called electrons.
electronic:Negatively charged particles. It is usually seen orbiting the outer region of the atom. Also a conductor of electricity in solids.
Basic: something fundamental or the basis of another thing or idea.
Muon: A type of unstable elementary particle. Most on Earth are formed when cosmic rays interact with atoms in the atmosphere. As leptons, muons belong to the same class of particles as electrons. However, its mass is about 200 times greater. Muons tend to be short-lived. It tends to survive for only 2.2 microseconds before decaying (converting) into an electron and two types of neutrinos.
neutron: An elementary particle that is one of the fundamental parts of matter and has no electric charge. Neutrons belong to a family of particles known as hadrons.
particle: A trace amount of something.
proton: An elementary particle that is one of the basic constituents of atoms that make up matter. Protons belong to a family of particles known as hadrons.
pyramid: A monumental structure with a square or triangular base and sloping sides that meet at a point at the top. The most well-known are the ancient Egyptian royal tombs made of stone.
quark: A family of subatomic particles, each carrying a partial charge. Quarks are the building blocks of particles called hadrons. Quarks come in types, or “flavors,” known as up, down, strange, charm, top, and bottom.
universe: The entire universe: Everything that exists beyond time and space. It has been expanding ever since it formed during an event known as the Big Bang about 13.8 billion years ago (which may take hundreds of millions of years or more).
volcano: A place where the Earth’s crust opens and magma or gas erupts from an underground reservoir of molten material. The magma rises through a system of pipes and channels and sometimes spends time in chambers where the magma bubbles with gas and undergoes chemical changes. This plumbing system can become more complex over time. This can also change the chemical composition of the lava over time. The surface around a volcanic opening can grow into mounds or cones as successive eruptions send more lava to the surface, where it cools and becomes solid rock.
