In chemistry, there are three definitions in the common use of the word base, known as Arrhenius bases, Brønsted bases and Lewis bases. All definitions agree that bases are substances that react with acids as originally proposed by G.-F. Rouelle in the mid-18th century.
focused and intense. a concentrated effort to stay in touch.
The Outside of the Earth
Human-computer interaction (HCI) is a multidisciplinary field of study focusing on the design of computer technology and, in particular, the interaction between humans (the users) and computers. While initially concerned with computers, HCI has since expanded to cover almost all forms of information technology design.
Substance Broader definitions of a base, to include substances that exhibit typical basic behaviour as pure compounds or when dissolved in solvents other than water, are given by the Brønsted-Lowry theory and the Lewis theory. Bases are chemical compounds that, in solution, are soapy to the touch and turn red
make (something) ineffective by applying an opposite force or effect.
the process of wearing or being worn by long exposure to the atmosphere.
tectonics is the theory that Earth's outer shell is divided into large slabs of solid rock, called “plates,” that glide over Earth's mantle, the rocky inner layer above Earth's core. ... It lubricates the undersides of Earth's tectonic plates, allowing the lithosphere to move around.2
is the chemical element with the symbol H and atomic number 1. With a standard atomic weight of 1.008, hydrogen is the lightest element in the periodic table. Hydrogen is the most abundant chemical substance in the universe, constituting roughly 75% of all baryonic mass.
Core Hottest Part on the Earth

Water: Seawater, water that makes up the oceans and seas, covering more than 70 per cent of Earth's surface. Seawater is a complex mixture of 96.5 per cent water, 2.5 per cent salts, and smaller amounts of other substances, including dissolved inorganic and organic materials, particulates, and a few atmospheric gases.

The basic sciences are defined as the scientific disciplines of mathematics, physics, chemistry, and biology. They are called basic sciences because they provide a fundamental understanding of natural phenomena and the processes by which natural resources are transformed.
An acid is any hydrogen-containing substance that is capable of donating a proton (hydrogen ion) to another substance. A base is a molecule or ion able to accept a hydrogen ion from an acid. Acidic substances are usually identified by their sour taste.
acid, also known as muriatic acid, is an aqueous solution of hydrogen chloride. It is a colourless solution with a distinctively pungent smell. It is classified as a strong acid. It is a component of the gastric acid in the digestive systems of most animal species, including humans.
But in chemistry, salt is a term used to describe a compound made by joining a positively charged acid with a negatively charged base. Table salt is the compound sodium chloride. It's composed of a positively charged sodium atom and a negatively charged chlorine atom.
An ion (/ˈaɪɒn, -ən/) is a particle, atom or molecule with a net electrical charge. The charge of the electron is considered negative by convention. The negative charge of an ion is equal and opposite to charged proton(s) considered positive by convention.
Hydrogen chloride (HCl), a compound of the elements hydrogen and chlorine, a gas at room temperature and pressure. A solution of the gas in water is called hydrochloric acid.
molecules like to stick together. ... Soap is able to break down the surface tension of water—that's part of what makes the soap a good cleaner. As the soap moves into the water, and the surface tension changes, the pepper no longer floats on top.
is a diatomic anion with the chemical formula OH−. It consists of an oxygen and hydrogen atom held together by a single covalent bond and carries a negative electric charge. It is an important but usually minor constituent of water.
Having neither acid nor basic properties; unable to turn red litmus blue or blue litmus red; said of certain salts or other compounds. Contrasted with acid, and alkaline.

The layer of rock that lies between the crust and the outer core of the Earth. It is approximately 2900 kms thick and is the largest of the Earth's major layers.
A weak point in the Earth's crust and upper mantle where the rock layers have ruptured and slipped. Faults are caused by earthquakes, and earthquakes are likely to reoccur on pre-existing faults.

A risk. An object or situation that has the possibility of injury or damage.
That point on the Earth's surface directly above the hypocentre of an earthquake.
(Drift) The theory, first advanced by Alfred Wegener, that they were originally one land mass. Pieces of the land mass split off and migrated to form the continents.
(Volcano) A volcano that resembles an inverted warrior's shield. It has long gentle slopes produced by multiple eruptions of fluid lava flows.
(Subduction) An elongated region along which a plate descends relative to another plate, for example, the descent of the Nazca plate beneath the South American plate along the Peru-Chile Trench.
A steep-sided volcano formed by the explosive eruption of cinders that form around a vent.
Molten rock containing liquids, crystals, and dissolved gases that forms within the upper part of the Earth's mantle and crust. When erupted onto the Earth's surface, it is called lava.
