MSA Review Vocabulary words D-F

Data: Collected information which can be quantitative (numerical) or qualitative (descriptive). Factual information used as a basis for reasoning, discussion, or calculation.
Decomposer: An organism that obtains energy from decaying organic material. (See Food chain, Food web, Consumer).
Density: The amount of material an object has in a specific amount of space.
Dependent variable: Factor whose value depends on the change the experimenter makes to the independent variable. It is the effect resulting from the scientific investigation. This quantity is plotted along the y-axis of a graph.
Deposition: Process by which sediments are deposited in a new location.
Disease: A condition of the body in which there is incorrect function due to heredity, infection, diet, or environment.
Displacement: One substance or object moving another substance or object, or taking its place.
Diversity of species: The number of different species present in an area.
Ductility: The ability of a substance to be stretched.
Earthquake: The moving and shaking of part of Earth's crust.
Ecosystem: A group/community of organisms interacting with their environment.
El Nino: A variation in worldwide weather patterns that recurs every three to five years and that is caused by changes in the wind, conditions over the Eastern Pacific Oceans.
Electric circuit: Continuous path that can be followed by charged particles.
Electric current: The flow of charged particles from one place to another.
Electrical conductivity: A property of a mineral to transmit electricity.
Electrical energy: Energy of electrical charges as a result of their position or motion.
Electricity: A general term for the physical phenomena that arises from the interaction of electric charges.
Electron: The negatively charged particle that moves around the nucleus of an atom.
Element: A substance that consists of only one kind of atom and cannot be broken down into simpler parts during a chemical reaction.
Energy: The ability to cause matter to move or change.
Energy transformation: When energy changes from one type to another.
Environment: The physical surroundings of an organism which includes the living and nonliving components.
Erosion: The carrying away of weathered soil, rock, and other materials on the Earth's surface by gravity, water, and wind.
Estuary: A coastal body of water that connects to the oceans so that fresh water from a river mixes with saltwater from the oceans, such as in the Chesapeake Bay.
Evaporation: Change of matter from a liquid state to a gaseous state at a temperature below its boiling point.
Evolution: Changes in species as a consequence of processes such as mutation and natural selection.
Expand: When most substances are heated their molecules move faster and further apart causing them to increase.
Extinction: The elimination of a species (also applicable to levels other than species) due to natural processes or human activity.
Faulting: The process of movement along a break or crack in Earth's crust.
Filtration: Process of separating a liquid and a solid by pouring the mixture through a fine mesh.
Flooding: An overflowing of a body of water onto normally dry land.
Fluorescence: A property of a mineral to glow with certain colors when exposed to an ultraviolet light.
Folding: The process of bending rock layers in Earth's crust.
Food: Scientific: substances that provide carbohydrates, lipids, and proteins as an energy source to organisms.
Food chain: The feeding relationships of species that transfer energy through the organisms in a community.
Food web: The complex interconnection of food chains in an ecosystem. (Compare Food chain)
Force: A push or a pull applied to an object.
Fossil: The remains or imprint of a prehistoric plant or animal.
Fracture: The property of a mineral in which it breaks along rough, jagged surfaces.
Fragmentation: The division of habitats that formerly occupied large, continuous areas into smaller areas by roads, fields, housing developments, and other human activities.
Frequency: The number of repetitions in a given interval of time.
Friction: The force that acts between materials that touch as they move past each other. Friction is caused by irregularities in the surface of objects that are touching.
Front: A boundary between air masses that have different temperatures and humidity. It is usually the site of unsettled weather conditions.
