atom: The essential unit of a chemical component. Atoms are made up of a dense nucleus that accommodates positively charged protons and uncharged neutrons. The nucleus is orbited by a cloud of negatively charged electrons.
cell: The smallest structural and useful unit of an organism. Usually too small to see with the unaided eye, it consists of a watery fluid surrounded by a membrane or wall. Relying on their measurement, animals are product of anyplace from hundreds to trillions of cells. Most organisms, corresponding to yeasts, molds, micro organism and a few algae, are composed of just one cell.
local weather: The climate situations that usually exist in a single space, generally, or over an extended interval.
local weather change: Lengthy-term, important change within the local weather of Earth. It might probably occur naturally or in response to human actions, together with the burning of fossil fuels and clearing of forests.
electrical energy: A move of cost, often from the motion of negatively charged particles, referred to as electrons.
electron: A negatively charged particle, often discovered orbiting the outer areas of an atom; additionally, the service of electrical energy inside solids.
excite: (in chemistry and physics) To switch power to a number of outer electrons in an atom. They continue to be on this greater power state till they shed the additional power via the emission of some kind of radiation, corresponding to mild.
fossil: Any preserved stays or traces of historical life. There are various several types of fossils: The bones and different physique elements of dinosaurs are referred to as “physique fossils.” Issues like footprints are referred to as “hint fossils.” Even specimens of dinosaur poop are fossils. The method of forming fossils is named fossilization.
fossil gas: Any gas — corresponding to coal, petroleum (crude oil) or pure gasoline — that has developed throughout the Earth over thousands and thousands of years from the decayed stays of micro organism, vegetation or animals.
gas: Any materials that may launch power throughout a managed chemical or nuclear response. Fossil fuels (coal, pure gasoline and petroleum) are a typical kind that liberate their power via chemical reactions that happen when heated (often to the purpose of burning).
inexperienced: (in chemistry and environmental science) An adjective to explain merchandise and processes that may pose little or no hurt to dwelling issues or the atmosphere.
greenhouse: A light-weight-filled construction, typically with home windows serving as partitions and ceiling supplies, during which vegetation are grown. It supplies a managed atmosphere during which set quantities of water, humidity and vitamins will be utilized — and pests will be prevented entry.
greenhouse gasoline: A gasoline that contributes to the greenhouse impact by absorbing warmth. Carbon dioxide is one instance of a greenhouse gasoline.
particle: A minute quantity of one thing.
photon: A particle representing the smallest doable quantity of sunshine or different kind of electromagnetic radiation.
photovoltaic: An adjective that describes the flexibility of sure applied sciences to transform daylight into electrical energy.
energy plant: An industrial facility for producing electrical energy.
renewable: An adjective for sources that may be endlessly changed (corresponding to water, inexperienced vegetation, daylight and wind). That is in distinction to non-renewable sources, for which there’s a finite provide — one that may basically be used up. These embody petroleum (and different fossil fuels) or comparatively uncommon components and minerals.
renewable power: Power from a supply that isn’t depleted by use, corresponding to hydropower (water), wind energy or solar energy.
photo voltaic: Having to do with the solar or the radiation it emits. It comes from sol, Latin for solar.
photo voltaic cell: A tool that converts photo voltaic power to electrical energy.
photo voltaic power: The power in daylight that may be captured as warmth or transformed into warmth or electrical power. Some folks consult with wind energy as a type of photo voltaic power. The explanation: Winds are pushed by the variations in temperatures and the density of the air, each of that are affected by the photo voltaic heating of the air, floor and floor waters.
solar: The star on the heart of Earth’s photo voltaic system. It’s about 27,000 light-years from the middle of the Milky Approach galaxy. Additionally a time period for any sunlike star.
waste: Any supplies which are left over from organic or different programs that haven’t any worth, to allow them to be disposed of as trash or recycled for some new use.
