| control | part of expierement that you dont change |
| convection current | when something (fluid or gas) is heated it rises ad then it cools and sinks and it consantly moves in a circle |
| lava | hot molten rock above the ground |
| magma | hot molten rock below the ground |
| Pangea | he theory that all the continents were connected before they split |
| sedimentary rock | a rock form when mud and other contents fuse together |
| density | d+=m/v how much matter you can fit into volume |
| mechanical advantage | output force/input force |
| efficany | output work/input work x 100% the efficany of a machine compares the output work to the input work. |
| what is a machines machanical advantage | the number of times a force exerted ona machine is multiplied by the machine |
| KHDBDCM | kilo,hecto,deca,base,deci,centi,mili |
| interpolate | finding data within graph |
| extapolate | finding data outside of the graph |
| linear | sraight line |
| nonlinear | not a line |
| latitude | horizontal lines on a map or a globe |
| longitude | vertical lines on a map or a globe |
| axis | imaginary line running vertically through an object |
| rotation | when an object spins around its axis |
| revolution | an object moves around another object ex.365.25 days=1 year |
| lunar month | the time it takes the moon to go around the earth ex.30 days or 29 days |
| astronomy | study of the moon, stars, objects in space |
| solisitce | the time of year that one of the poles is facing the sun |
| equinox | when the sun shines in the equator |
| new moon | the sun lights the side of the moon facing away from earth. the side of the moon that faces the earth is dark |
| waxing creasent | you see more and more of the lighted side of the moon. this si called a waxing cresent moon |
| first quarter | you see half of the lighted side is the moon |
| waxibg gibbous | the moon continues to wax. the moon is called gibbous |
| full moon | you see the whole lighted side of the moon |
| waning gibbous | the fraction of the lighted side of the moon that you see gets smaller each day |
| third quarter | you can see half of the moons lighted side |
| waning creasent | you see a cresent again |
| tides | the moon revolves aroundthe earth in an oval shape. when the moon is close to the earth, gravity pushes down on the water, and since the water has no where else to go it spreads out and creates a high tide every 12 hours |
| solar eclipse | moon blocks sun light to the earth |
| lunar | the earth blocks the moons sunlight |
| what happens during a solar eclipse? | the moon blocks the sun to the earth. the part of the earth that gets darkis an UMBRA or moons shadow |
| what happens to the places near the umbra? | they excpierence a partial eclipse or a PENUMBRA where it gets partially dark but the sun manages to spread a little light |
| rockets | they fly by action-reaction. when 2 objects are together and they push they will both go different ways. ex.if a man on roller skates fires a gun at a target the man will go backwards and the bullet goes forward |
| comet | a large dirty chunk of ice and dust(size of earth mounains) .comets make eliptical around the sun |
| asteroid | a giant chunk of rock. most are found between the orbits of Mars+Jupitar |
| meteriods | pieces of comets or asteoids |
| meteor | meteorid that burns up in earths atmosphere from friction |
| what is the rock cycle? | ingeous-metimorphic-sedimentary |
| wheather | the condition of earths atmosphere at a paticular time and place |
| atmosphere | the laer of gases that surrounds the planet |
| ozone | a form of oxygen which contains 3 oxygen atoms in each molecule instead of the usual 2, is sometimes found in air-o3-it forms when lightening interacts with oxygen |
| plate tectonics | earths plates are moving slowly in various directions |
| plate | major piece of earths crust that moves |
| force | push or pull |
| acceleration | the rate at which velocity changes |
| inertia | the tendancy of an object to resist change in motion |
| what are the 6 simple machines | inclined plane, wedge,screw,lever,wheel and axle and pulley |
| what are the 3 types of levers? | first class ex.seesaw second-class ex.bottle openers third class-ex. shovles |
| lithosphere | the solid portion of the earth, the crust and upper mantle |
| hydrosphere | the water on or surrounding the surface of the globe, including the water of the oceans and the water in the atmosphere. |
| troposphere | the lowest layer of thr atmosphere |
| fossils fuel | materials suc as coal that are burned to release their chemical energy |
| fulcrum | the fixed point around which a lever pivots |
| joule | a unit of work equal to one newton-meter |
| climate | the composite or generally prevailing weather conditions of a region, as temperature, air pressure, humidity, precipitation, sunshine, cloudiness, and winds, throughout the year, averaged over a series of years. |
| condenses | to become liquid or solid, as a gas or vapor |
| compound machine | a device that combines two or more simple machines |
| radiation | the transfer of energy by electromagnetic waves |
| precipitation | a solid that forms from a solution during a chemical reaction |
| what is Newtons 3rd Law of Motion? | states that if one object exerts a force on another object, then the second object exerts a force of equal strength iin the opposite direction |
