| Reactant | The materials of the reaction that cause it to happen |
| Product | The materials formed from the reaction |
| Flammability | Able to burn, or catch fiew |
| Precipitate | Material formed as a result of chemical change |
| Phase Change | Changing from one state of matter to another |
| Physical Property | Characteristic that can be observed with your senses or measured |
| Period | A row on the periodic table |
| Group or Family | A column on the periodic table |
| Atomic Mass | The average number of protons and neutrons in an atom |
| Element | A pure substance that has the 2 or more of the same atoms |
| Compound | Two or more elements chemically bonded, example water |
| Conductivity | Able to transmit electricity, heat |
| Unconformity | When a rock disturbs a series of undisturbed layers |
| Law Of Superposition | In an undisturbed set layer of rock, the younger rock is on top and the oldest rock is on the bottom |
| Half-Life | When the amount of a radioactive element is decreased by half after a period of time |
| Absolute Dating | Using radioactive elements to determine the EXACT age of a fossil, rock, or artifact |
| Relative Dating | Using the Law of Superposition and index fossils to give an estimate of a fossil or rock layers |
| Index Fossils | Fossils that we know the exact age, but use it for a comparison |
| Convergent Boundary | When plates push together and form mountains |
| Divergent Boundary | When plates move away from each other and form mid-oceans ridges, and new crust. |
| Transform Boundary | When plates slide or rub against each other forming faults and earthquakes |
| Fault | A break or fracture in rock layers |
| Igneous Rock | Rock formed by material from volcanoes |
| Weathering | Breaking down of rock by movement (Mechanical), interactions with living things (Biological) and reactions (Chemical) |
| Ice Core | A sample of ice that shows the atmospheric information of an area |
| Geologic Time Scale | The organization of the Earths history that connects events that happened to the structure of the Earth to the changes in the organisms |
| Mantle | Middle layer of the Earth that causes the tectonic plates to move |
| Convection Current | Cycling of material - warm material is less dense and rises, cooler material is more dense and sinks |
| Pangaea | Super-continent that existed over 250 mya |
