| Question | Answer |
|---|---|
| What are the steps of the scientific method? | A) state the problem B)gather data C)form a hypothisis D)experiment E)data F)conclusion |
| What is a control group? | basis of comparison, the group that doesn;t get the iv, the morn group |
| what is the indepenedent variable? | what "i" chacnge in am experiment. the manipulated cariable. goes on the x axis |
| what is the dependent variable? | what happens as a result of what "i" did in am ecperiment. the reactive variable and it goes on the y axis |
| what is a hyothesis? | an educated guess about an outcome or a problem. |
| how do you form a hypothesis? | if, then the statement |
| what are the parts of a graph? | a. title (must reflect all cariables) B. each axis labled c. data d. legend e. units if applicable |
| where do the independent and the depent variable go on a graph? | the iv on the x axis and the dv on the y axis |
| how do you remeber where the variables go? | DRY MIX |
| if there is an axident in lab, what do you do first? | contact the teacher |
| list the SI unit prefixes in order from largest to smallest. | kilo hector deca base deci centi milli |
| what SI unit do you use for: mass distance volume | gram metter liter |
| what does a triple-beam balance measure? | mass |
| what does a ruler measure? | distance |
| what does a graduated cylinder measure? | volume |
| what does a beaker measure? | volume |
| define the following (include its location and charge): proton electron neutron | located in the nucleus and positively charged ion located outside the nucleus and has a negitive charge located in the nucleus and is a neurtal ion |
| what is an ionic bond? | electrons are given or received, bonding is based on the change in charge (opposites attract) NaCL is an exsample |
| what is a covelant bond? | electrons are shared h20 is an exsample |
| how do you know if two elements have similar properties? | if it is in the same group/family |
| what is the law of conservation of mass? | the mass of the reactants will equal the mass of the products |
| what are the characteristics of a physical change? | the form or apperance of matter changes, but not its composition, dissolving, changing state/phases, absorption,cutting/tearing/smashing |
| what are the characteristics of a chemical change? | changing from one substandce into a new substance, color change, forming gas or a solid, producing light, odors, giving off heat, absorbing heat |
| define family as it relates to the periodic table | ussually the verical columns of elemnts that have similar physical and chemical properties |
| define period as it relates to the periodic table | a row of elemts, the properties graually change predictably across the period |
| what is an atomic number | showes the number of protons in the nucleus |
| what is atomic number | the weighted average of the isotopes of an element. measured in mass units |
| what is the deffintion of a mineral? | inorganic-doesn't come from living things always a solid-has volume and shape definite chemical compostion- made of a single sure substance or element crystalline form-flat sides, sharp edges adn corners |
| what are the two ways that minerals will form? | as magma cools, minerals will crystalize some minerals crystals will form compounds dissolved in liquids |
| what are the different types of luster? | metallic nonmetallic: dull, pearly, silky, earthy |
| what is streak | the color of the powder scraped off a mineral when rubbed against a rough surface |
| what is cleavage | breaks smooth, definite surfaces, same everytime |
| what is fracture | breaks in rough or jagged surfaces |
| what are some special properties of minerals | reaction to acid- some minerals will bubble in acid magnestim- some special minerals will be magnetic smell- some will have distinct odors taste- some have a distinct taste |
| according to teh rock cycle, does the mass of thr rock change as it goes from one rock type to another? explain why or why not | no. law of conservation of matter |
| what materical fromes igneous rock | magma and lava |
| what processes from sediment | weathering and erosion |
| what processes change sediment into sedimentary rock | compaction |
| what processes are known as metamorphism | heat and pressure |
| what is the rock type and classification of rocks formed by volcanos` | intrusice and extrusive igneous |
| what is the rock type and classification of these rocks form layer beacuse of heat and pressure | foliated metamorphic |
| what is the rock type and classification of rocks that form by chemicas crystallizing out of solution | non-clastic rock (chemical) sedimentary |
| what is the rock type and classification of rocks that are made of preciously lliving organisms | organic non-clastic (chemical) fossils sedintary |
| what is the rock type and classification of rocks formed by magma cooling underground | intrusive igneous |
| what is the rock type and classification of these rocks form when rocks are changed by chemcial reactions | foliated and nonfoliated metamorphic |
| what is the rock type and classification of these rocks are made of smaller rock pieces and particles | clastic rock (detrial) |
| what is mechanical weathering? | weathering by physical processes |
| what are some direct causes of mechanical weathering | growing plants, burrowing animals, and expanding ice |
| what is chemical weathering | chemicals dissolve the minerals in rocks or change them into differnt minerals |
| what is the difference betwwn mechanical and chemical weathering | in cw the rocks composition is changed. in mw the rock is physically changed only |
| what is soil made of | meathered rock, decayed organic matter, mineral fragments, water, and air |
| what are some factors that affect soil formation? | climate,slope,type of rock,types of vegetation,and length of time that rock has been weathering |
| why is topsoil important | provide nutrients for plants |
| what is erosion | wearing away of surface and matericals by gravity,water,wind,and glaciers |
| what is deposistion | process where sediments are dropped by erosion agents as they loose engergy |
| how are erosion and deposition different | erosion is the wearing away of rock, deposition is where the parts that were worn away are dropped |
| what factors affect the amount of runoff | amount of rainfall,length of time it falls, steepness,or slope of land,and anount of vegetation |
| what is an iceage | periods of widespread glaciation |
| what characteristics do young rivers have | gloces swiftly through a narrow valley. may have rappids and waterfalls. erodes the bottom faster than the sides and the v shapped valleys |
| what characteristics does a mature river have | flows smothly through the valley, erodes more on the sides forms meander and oxbow lates and caves a flat broad valley floor called a floodplain |
