| abiotic factors | the nonliving factors in an ecosystem |
| biotic factors | the living factors in an ecosystem |
| grassland | an ecosystem that has fertile soil covered with tall grasses |
| terrestrial ecosystem | a land-based ecosystem |
| estuary | a body of water in which fresh water from a river meets and mixes with salt water from the ocean |
| aquatic ecosystem | a water-based ecosystem |
| salt marsh | a flat area of land where salt water overflows |
| producer | a living thing that makes its own food |
| consumer | a living thing that gets energy by eating other living things |
| force | a push or a pull |
| speed | a measure of how far an object moves in a certain amount of time |
| distance-time graph | a line graph that shows an objects motion |
| friction | a force that acts between surfaces that touch each other; tends to slow an object's motion |
| gravity | a force that pulls objects towards each other |
| physical change | a change in which no new material forms |
| chemical change | a change in which one or more new types of matter form |
| thermal energy | the energy of moving particles that make up all matter - heat |
| convection | the transfer of thermal energy by the movement of liquids or gases |
| insulator | a material that heat does NOT pass through easily |
| conductor | a material through which heat can move easily |
| conduction | the transfer of thermal energy between things that are touching |
| radiation | the transfer of energy by electromagnetic waves |
| rain gauge | a tool used to measure the amount of precipitation that falls |
| wind vane | a tool that shows wind direction - where the wind is coming from |

| stratus clouds | low, sheetlike gray clouds |
| air mass | a large body of air with the same temperature and humidity throughout |
| cumulus clouds | puffy clouds that are flat on the bottom - signal fair weather |
| front | a place where two different air masses meet |
| cirrus clouds | wispy clouds that are made of ice crystals - signals a change in weather is coming |
| cold front | cold air mass bumps against a warm air mass - causes strong storms and cooler temperatures |
| cumulonimbus clouds | puffy, layering clouds that are flat on the bottom and dark - bring rain, thunder, and lightning |
| warm front | warm air mass meets a colder air mass and slowly rises over it - brings rain and warmer temperatures |
| stationary front | forms when two air masses meet and stop moving - brings clouds and precipitation |
| transpiration | the process by which plants release water vapor into the air from their leaves |
| condensation | the change from a gas to a liquid |
| precipitation | water that falls from the atmosphere as rain, snow, sleet, or hail |
