| A | B |
| Periodic table of elements | display of chemical elements, arranged by atomic number, electron configuration, and common characteristics |
| Earth Crust | the outer layer on which we live |
| Mantle | 3000 km deep, and made up of magnesium and iron |
| tectonic plates | made up of crust and mantle, have a tendency to shift causing earth quakes |
| Outer core | made up of iron and nickle. Creates a magnetic feild |
| Inner core | very hot but in a solid state because of immense pressure |
| Igneous rock | formed through the cooling and solidification of magma or lava |
| Marble | metamorphic rock, most commonly calcite or dolomite |
| Kinetic energy | the amount of energy an object possesses due to its motion |
| Thermal energy | a rise in temperature causes atoms and molecules to move quickly and collide with one another |
| Chemical energy | potential of a chemical substance to undergo a chemical reaction to transform into other substances. |
| Chemical reaction | the process which leads to a chemical transformation from one set of chemicals to another |
| Matter | anything that occupies space |
| Gas | a substance that will expand molecules freely to take up the entire space or container |
| Solid | firm and stable in shape |
| Atmosphere | the envelope of gasses surrounding Earth or another planet |
| Pressure | continuous physical force exerted on or against an object |
| Force | strength or energy as an attribute of physical action or movement. |
| Supernova | a star that suddenly increases greatly in brightness because of a catastrophic explosion that ejects most of its mass. |
| Mars | fourth planet from the sun and second smallest in the solar system |
