Earths Physical Syst
| Question | Answer |
|---|---|
| any material with mass and takes up space | matter |
| says matter can be transformed from one type of substance to another but not created or destroyed (nutrients, toxic pollutants) | law of conservation of matter |
| chemical subtances with properties that cant be broken down in subtances with other properties | elements |
| elements that organisms need for survival | nutrients |
| smallest units that have elemnt chemical properties | atoms |
| atom that gained or lostt one or more electrons | ion |
| atoms of same element with differeing number of neutrons | isotopes |
| radioactive isotopes of an element | radisotopes |
| combination of two or more atoms chemicslly bonded togeather | molecules |
| molecule made of two or more different elemts (water, carbon dioxide) | compound |
| atoms and molecules togeather not reacting with each other | mixtures |
| evenly distributed mixtures | solution |
| made of carbon atoms joined with covalent bons (N,O,S,P) | organic compounds |
| organic compound only containing hydrogen and carbon | hydrocarbs |
| long chains of repeated moleculues; protiens, carbs, nucleic acids | polymers |
| polymers of amino acids | protiens |
| polymer containing DNA & RNA herditary information | nucleic acids |
| moleclues making up nucleic acids | nucleotides |
| DNA coding | Genes |
| simple and complex sugars; cellulose, glclose, chitin | carbohydrates |
| molecules that dont dissolve in water - fats, oils, waxes | lipids |
| capacity to change composition or position of matter; involved in every natural physical phenomenon; Needed to organize matter into complex forms; cell structure | energy |
| energy of position or composition (a river behind a dam) | potential energy |
| energy of motion (river rushing down stream) | kenetic energy |
| energy can change from one another but not created nor dystroyed | first law of thermodynamics |
| energy can change from a more ordered to less ordered state as it changes forms | second law of thermodynamics |
| releases energy across electromagnet system; filtered by atmosphere; reflected by land or water | the sun |
| organisms that use sun radiation to produce food | autotrophs |
| autotrops transforming molecules into sugar molecules | photosynthesis |
| energy released from photosynthesis use to power biochemical reactions | cellular respiration |
| jets of heated water by geothermal energy heating cool water | hydrothermal vents |
| process organisms produce sugars living near vents using chemical potentional energy | chemosynthesis |
| solid aggregation of minerals | rocks |
| naturally occuring soild with chemical composition & chemical structure; one or multiple element composition, metallic or nonmetallic, classified by hardness & luster | minerals |
| when magma rises and cools at plate boundaries | igneous rocks |
| change by heat & preassure without melting | metamorhpic rocks |
| form from mineral fragments deposited, compactred and cemented | sedimentary rocks |
| solid rock & liquid metal; gets hotter more deep | earths layer composition |
| crust and hard upper region of the mantle; broken into tectonic plates; consist of continental, oceanic or both crusts; tectonic plates move very slowly | lithosphere |
| earthquakes and volcanos are where multiple or two meet | plate boundaies |
| 2 plates colliding, one goes below the lighter one | convergent plate boundary |
| 2 plates moving apart | divergent plate boundary |
| 2 plates slide side by side | transform plate boundary |
| sudden shaking due to moving plates, stresses inside a plate or volcanic activity | earthquake |
| earthquakes underground location where the earthquake is originate | focus |
| earthquakes point directly above focus on earths center | epicenter |
| when magma works its way from asthenosphere, exiting as lava | volcanos |
| volcano where plates meet forming volcanos, hot mantle melts rocks | hotspots |
| suddent movement of unstable rock/soil due to forces triggered by heavy rains or an earthquake | landslides |
| series of high, long, fast, moving water waves caused by displacement of large quanitities of underwater due to an earthquake or alike | tsunami |
