| Term | Definition |
| Macronutrient | Required in large amounts, "Big Six" |
| Micronutrients | Required in small amounts, 18 of them |
| Residence Times | Average length of time an element is stored in a certain resevoir before being transferred to the next resevoir |
| Flux (rate of transfer) | Amount of an elemnt that leaves or enters a reservoir per unit of time |
| Limiting Factor | Stops growth from happening |
| Evaporation | Water turns from a liquid to a gas |
| Candensation | When water turns from a gas to a liquid |
| Percipitation | Water turns from a gas to a liquid or solid |
| Respiration | Breathing out CO2 |
| Run-off | Water running along the soil/earth and drains into rivers and streams |
| Percolation | Water being filtered through soil down through the gound; filtration |
| Consumption | Ingesting water |
| Transpiration | Plants release H2O through their leaves |
| CO2 | Carbon Dioxide |
| C6-H12-O6 | Sugar |
| CH4 | Methana |
| CO 3 -2 | Carbonate |
| HCO3 -2 | Bicarbonate |
| Photosynthesis | Process by which plants take in light energy and turn it into chemical energy-chloroplast which feeds the plant |
| Cellular Respiration | [C6 H12 O6 + O2] forms [CO2 + H20 + energy] Sugar and oxygen change into Cardon dioxide out of the plant and expel water |
| Assimilation/Biosynthesis | Consumption of Carbon Dioxide which triggers the process of creating carbohydrates for energy |
| Lithification | Limestone is created under intense heat and pressure on carbon atoms |
| Decomposition | The break down of dead organic matter which transfers carbon from dead organisms into the soil for the consumption of plants |
| Coalification | Dead matter and animals are turned into fossil fuels under intense heat and pressure |
| Combustion | The burning of fossil fuels that releases carbon into the atmosphere |
| Uplifitng | Rock or soil being shifted or lifted out of the ground |
| Weathering | The chemical or mechanical weathering of inorganic matter. Ex: rain on a rock, the rain finds its way into cracks of the rocks. When the water freezes it expands the rock eventually breaking the rock apart. Chemical weathering-acid rain, etc. changes the chemical structure of any inorganic structure. |
| Erosion | Run off causes soil and other inorganic materials to run into streams and rivers |
| PO4 3- | Phosphate |
| Eutrophifaction | Increased amounts of fertilizer and other nutrients getting into the soil, and then bodies of water that causes toxic algae blooms |
| N2 | Nitrogen gas |
| NO3 1- | Nitrate ion |
| NO2 1- | Nitrite ion |
| NO2 | Nitrogen dioxide gas |
| NH3 | Ammonia |
| NH4 +1 | Ammonium |
| Nitrgen Fixation | N2 in the atmosphere is converted into nitrate or NH3 |
| N2O | Nitrious Oxide |
| De-nitrification | Bacteria in soil/water "strip" oxygen off NO3 -1 and convert it back to atmosphereic nitrogen |
| Biosynthesis/Assimilation | NO2 -1/NO3 -1 make proteins and amino acids |
| Leaching | Soil erosion |
| Ammonifiaction | Decomposition releases NO3 -1 into the soil |
| Nitrification | NH3 is toxic, so bacteria convert it into the non-toxic (NO2-/NO3 -1) |
| Fertilizer | Poop-lots of nitrogen |
| Combustion | Burning of fossil fuels |
| Igneous Rock | Created by heat and pressure |
| Sedimentary | Caused by erosion and weathering, layers up layers of sediment |
| Metamorphic Rock | Caused by heat and pressure in the earths crust |
