| Term | Definition |
|---|---|
| mass | amount of matter in an object |
| volume | amount of space an object occupies |
| density | mass and volume; how tightly packed the molecules are |
| independent variable | controlled by experimenter |
| dependent variable | factor being observed in an experiment |
| constant | factors that remain the same for all set-ups |
| orbit (revolution) | path around the sun=year (or moon's path around a planet) |
| rotation | spin on an axis=day |
| solar eclipse | earth-moon-sun; sun is blocked |
| lunar eclipse | sun-earth-moon; earth shadows moon |
| humidity | amount of moisture in the air |
| altitude | distance above sea-level |
| latitude | distance from the equator |
| evaporation | liquid to gas |
| condensation | gas to liquid |
| precipitation | rain, snow, sleet, hail; water returns to Earth's surface |
| front | boundary between two air masses |
| climate | weather over a period of time |
| weather | state of the atmosphere at a given place and time |
| lithosphere | solid rock portion of Earth's surface |
| hydrosphere | water on Earth's surface |
| Pangea | super continent |
| weathering | break down of Earth's surface into sediments |
| erosion | carrying away/transfer of Earth's sediments |
| folding | bending of rock layers |
| faulting | breaking of rock layers |
| divergent boundary | two plates pull apart |
| convergent boundary | two plates collide |
| transform fault boundary | two plates slide past one another |
| convection currents | heating and cooling of mantle-causes plates to move |
| principle of superposition | deeper rock layers are older than surface layer |
| unconformity | gap in geologic history due to missing rock layers |
| evolution | change in a population of a species over time |
| gradualism | evolution occurs slowly and steadily |
| fossils | remains of life |
| natural selection | survival of the fittest |
| variation | differences between organisms of the same species |
| adaptation | variations that aid in survival |
| mutation | change in gene or chromosome that leads to variations |
| asexual reproduction | one parent; identical offspring |
| sexual reproduction | two parents; variety of offspring |
| fertilization | union of sperm and egg |
| mitosis | division of body cells=identical cells |
| meiosis | creation of sex cells=1/2 as many chromosomes |
| internal fertilization | occurs inside the body (humans) |
| external fertilization | occurs outside the body (fish) |
| chromosome | in nucleus; has genes; carries genetic information |
| genotype | gene make-up of a trait (Tt) |
| phenotype | appearance of a trait (tall) |
| dominant | powerful gene; blocks recessive; capital letter |
| recessive | weak gene; only shows up in homozygous form; lower-case |
| hybrid | two different genes (one dominant, one recessive) |
| homozygous | two of the same genes (either both dominant or both recessive) |
| arteries | vessel that carries rich blood away from the heart |
| veins | vessel that carries depleted blood back to the heart |
| capillaries | vessel where exchange occurs |
| red blood cells | transport oxygen and CO2 |
| white blood cells | aid in immunity |
| platelets | help heal wounds |
| charge | gain or loss of electrons |
| resistance | slows the flow of electricity |
| voltage | causes energy to flow; battery |
| potential difference | power difference between battery and wires |
| current | speed of electric flow |
| conductor | loosely bound electrons-allows electricity to flow |
| insulator | tightly bound electrons-resists electrical flow |
| current electricity | flowing electrons |
| static electricity | gain or loss of electrons |
| electrical discharge | result of electrons moving off a charged object |
| ground wire | highly conductive, protective source for high electrical output |
| permanent magnet | keeps magnetism |
| induced magnet | temporary magnetism |
| electromagnet | caused by the flow of electricity through a coiled wire |
| magnetic poles | greatest magnetic force |
| magnetic field | area around a magnet where magnetic forces act |
