bond: (In chemistry) a semi-major attachment between atoms or groups of atoms within a molecule. It is formed by the attractive forces between participating atoms. When combined, atoms act as units. To separate the constituent atoms, the molecule must be energyed as heat or other types of radiation.
Computer Model: A program run on a computer that creates a model or simulation of a real function, phenomenon, or event.
crystal: (adj. crystalline) A solid consisting of symmetrically ordered three-dimensional arrangements of atoms or molecules. It is the tissue structure photographed by most minerals. For example, apatite forms six-sided crystals. The crystalline components of rocks are usually too small for auxiliary eyes to see.
diamond: One of the most difficult known substances and rarest gems on the planet. When carbon is compressed under very strong pressure, diamonds form deep within the planet.
Europe: With the 95-named Moon of Jupiter, one of the most crossed satellites on Earth. At 1,951 miles in diameter, Europe has a network of dark lines on bright, icy surfaces.
exoplanet: Abbreviation for Extosola planet is a planet that orbits stars outside the solar system.
Glacier: A slow moving river of hundreds or thousands of meters of ice. The glacier is located in mountain valleys and also has ice sheet sections.
Residence possible: A suitable place for humans and other living creatures to live comfortably.
hydrogen: The lightest element in the universe. As a gas, it is colorless, odorless and highly flammable. This is an integral part of many of the fuels, fats and chemicals that make up living tissue. It is made of a single proton (which functions as its nucleus) surrounded by orbitals by a single electron.
lattice: (in chemistry) a three-dimensional arrangement of atoms or ions in a crystal.
liquid: A material that flows freely but maintains a constant volume such as water or oil.
Mantle: (in geology) Thick layer of Earth beneath the outer crust. The mantle is semi-solid and is generally divided into upper and lower mantles.
molecule: An electrically neutral group of atoms representing the amount of a possible amount of a compound. Molecules can be made of a single type of atom or of different types. For example, oxygen in the air is made up of two oxygen atoms (o2), but water is made up of two hydrogen atoms and one oxygen atom (H2o).
month: Natural satellites of all planets.
neutron: A subatomic particle that is one of the basic parts of matter, which is a chargeless subatomic particle. Neutrons belong to a family of particles known as hadrons.
Nutrients: Vitamins, minerals, fats, carbohydrates, or proteins that plants, animals, or other organisms need as part of their food to survive.
particle: The amount of something.
Physicist: A scientist who studies the properties and properties of matter and energy.
planet: A large celestial object that orbits stars but unlike stars, does not produce visible light.
plastic: Any of a series of materials that can be easily deformed. Or synthetic materials made from polymers (long strings of some building block molecules) that tend to be lightweight, inexpensive and resistant. (adj.) Materials that can be adapted by changing the shape or function.
Plasticity: Adaptable or reconstructible.
Pressure: A uniform force is applied to the surface, measured as force per unit of region.
Solar System: The eight major planets and their moons in orbit around our Sun, along with small bodies in the shape of dwarf planets, asteroids, metstones and comets.
solid: Hard and stable shape. It is not a liquid or a gas.
theory: Explaining some aspects of nature based on extensive observations, tests and reasons (in science). Theory is also a way of organizing a wide range of knowledge that applies to a wide range of situations, explaining what happens. Unlike the general definition of theory, science theory is not merely a prediction. An idea or conclusion based on a theory – not yet based on solid data or observations – is called a theory. Scientists who use mathematics and existing data to predict what will happen in new situations are known as theorists.
Titan: (in astronomy) one of many moons on the planet Saturn.
Characteristics: Something distinctive feature.
