atmosphere: An envelope of gas surrounding the Earth, another planet, or the Moon.
chemicals: A substance formed when two or more atoms combine in a certain ratio and structure. For example, water is a chemical produced when two hydrogen atoms combine with one oxygen atom. Its chemical formula is H2O. Chemistry can also be used as an adjective to describe the properties of materials that result from various reactions between different compounds.
cloud: A plume of molecules or particles, such as water droplets, that moves under the action of external forces such as wind, radiation, or water currents. (in atmospheric science) An airborne mass of water droplets and ice crystals that moves as a plume, usually high in the Earth’s atmosphere. Its movement is driven by the wind.
data: Facts and/or statistics collected together for analysis. They are not necessarily organized in a way that gives them meaning. For digital information (the type stored by computers), these data are typically numbers stored in binary code and represented as strings of 0’s and 1’s.
density: A measure of how condensed an object is. It is found by dividing its mass by its volume.
electricity: A flow of charge that results from the movement of negatively charged particles, usually called electrons.
element: A component of a larger structure. The smallest unit of each of the more than 100 substances (in chemistry) is one atom. Examples include hydrogen, oxygen, carbon, lithium, and uranium.
Hue: A color or shade of a color.
iron: A metallic element commonly present in the minerals of the Earth’s crust and its hot core. This metal is also found in cosmic dust and many meteorites.
lightning: A flash of light caused by an electrical discharge that occurs between clouds or between a cloud and something on the ground. The current heats the air rapidly and can cause sharp thunderclaps.
metal: Something that conducts electricity well, is shiny (reflective), and malleable (that is, it can be changed shape by heat without much force or pressure).
meteor: (adjective: meteorite) A chunk of rock or metal that crashes into the Earth’s atmosphere from space. In space, they are known as meteorites. If you see it in the sky, it’s a meteor. And when it hits the ground, it is called a meteorite.
meteorologist: A person who studies weather and climate phenomena.
molecule: An electrically neutral group of atoms that represents the smallest possible amount of a compound. Molecules can be made up of a single type of atom or different types of atoms. For example, oxygen in air has two oxygen atoms (O2) However, water has two hydrogen atoms and one oxygen atom (H2oh).
nickel: Number 28 on the periodic table of elements, this hard, silvery element is resistant to oxidation and corrosion. This makes the coating suitable for use with many other elements and multimetallic alloys.
oxygen: A gas that makes up about 21% of the Earth’s atmosphere. All animals and many microorganisms require oxygen to facilitate growth and metabolism.
paranormal phenomenon: An event or phenomenon that deviates from or exceeds what is considered normal. Examples include ghosts, zombies, telekinesis, and curses.
range: the total extent or distribution of something. For example, a plant or animal’s habitat is the area in which it naturally occurs. (in mathematics or measurement) a range over which a value varies (such as from the highest temperature to the lowest temperature). Also, the distance something can reach or be perceived.
sea: Ocean (or area that is part of the ocean). Unlike lakes and streams, sea water, or ocean water, is salty.
subtle: an adjective that describes something that may be important but is difficult to see or describe. For example, the first cellular changes that signal the development of cancer may be only slightly different, small and difficult to distinguish from nearby healthy tissue.
