| Molecule | The smallest particle of a substance that has all of the physical and chemical properties of that substance |
| Compound | a thing that is composed of two or more separate elements; a mixture |
| Hydrocarbon | any of a class of organic chemical compounds composed only of the elements carbon and hydrogen |
| solution | is a homogeneous type of mixture of two or more substances. A solution has two parts: |
| Macromolecules | any very large molecule, usually with a diameter ranging from about 100 to 10000 angstroms |
| Protein | A molecule made up of amino acids |
| Nucleic acids | Nucleic acids are large biomolecules that play essential roles in all cells and viruses |
| Carbohydrates | a type of macronutrient found in certain foods and drinks |
| Lipids | Lipids are fatty compounds that perform a variety of functions in your body |
| pH | is a logarithmic scale used to specify the acidity or basicity of aqueous solutions |
| feedback loop | A feedback loop is a biological occurrence where the output of a system amplifies the system (positive feedback) or inhibits the system |
| Erosion | the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust |
| Geosphere | the earth itself: the rocks, minerals, and landforms of the surface and interior |

| crust | the outermost shell of a terrestrial planet |
| mantle | the mostly solid bulk of Earth's interior |
| core | The central or innermost portion of the Earth, lying below the mantle. |
| tectonic plate | A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere |
| landforms | features on the Earth's surface that make up the terrain |
| Deposition | rocks or particles of soil or silt are carried from one location and placed in another, usually by moving water or wind. |
| evaporation | the process that changes liquid water to gaseous water (water vapor). |
| transpiration | the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers |
| precipitation | rain, snow, sleet, or hail — any kind of weather condition where something's falling from the sky |
| condensation | Condensation is the change of the state of matter from the gas phase into the liquid phase, and is the reverse of vaporization. |
| aquifier | a body of rock and/or sediment that holds groundwater |
| groundwater | water present beneath Earth's surface in rock and soil pore spaces and in the fractures of rock formations. |
