syncline | downward buldge |
lithosphere | outer zone, cool and rigid |
seismic waves | durring an earthquake potential energy turns to kinetic energy |
anticline | fold produce upward buldge |
volcano | opening in crust that has released lava and molten rock |
asthenosphere | hot and semi liquid (earth) |
Moho | sudden increase in volosity of a seismic wave |
geologic time | the war to measure time for earth because it has been around so long |
weathering | rock is broken into smaller particals |
Erosion | small particals are taken away by wind water ice and gravity |
zenith | highest point of the sky |
deposition | building up of eroded particals / sedimates |
fossils | past organisms that have left evidence of existence in rock |
solstice | noon sun is overhead at the tropics |
crust | outermost layer of Earth |
mantle | middle layer of Earth |
Lava | magma that reaches earths surface |
Earth quake | movement of earth's crust occurs when plates shift and releases stored or potential energy |

orbit | The path a body follows as it revolves around another |
revolution | movement of one body around another |
solar system | earth and other planets |
parallax | the apparent change in the position of an object caused by change in position of the observer |
convection | the circular flow due to the heating and coolin in earths mantle |
asteroids | small irregular shaped solid bodies, revolve around sun |
corona | outer layer of suns atmosphere |
equator | equidistant from poles |
focus | area along a fault where rocks first bread and move where earthquake starts |
crater | circular indentation in the moon created by meteorites |
axis | the lene that extends through earth north and south pole |
rotation | spinnein of earth on its axis |
deformation | changes in the shape and structure of earths crust |
fault | fracture in the earths crust where movement has occured |
chromosphere | 2nd layer of suns atmosphere |
kilogram | SI unit of mass |
density | measure how much matter in a given volure |
meteor | the light resulting from entry of atmosphere - shooting star- |
meteoride | chunk of rock or metal smaller than asteroid |
meteorite | when a meteoroid does not completley burn up in atmosphere hitting earth |
Scientific Method | Steps:Observe, Hypothesis, Record, Analyze, Repeat |
Mesosphere/Mantle | Solid and rigid iron and magnesium; makes up 82 % volume and 68% of earths mass |
Outer Core | liquid, molten iron, source of magnetic field |
Inner Core | High pressure, high density, high temp. |
Time Zones | divides Earth into 24 time zones, each time zone is 15 degrees wide. Starts at the prime meridian @ Greenwich england. there are 4 time zones on continental U.S. Latest is Eastern Time, then central, then Mountain and Pacific time. |

Convergent Boundaries | where two plate boundaries collide |
divergent boundaries | where two plates move away from each other |
transformant boundaries | where two plates slide in opposite directions beside each other |
thrust fault | where the hanging wall rides up and over the footwall as a result of compression |
daughter theory | piece of Earth split off to form the moon |
sister theory | the Earth and the moon formed from gas and dust during the formation of the solar system |
Capture Theory | moon formed elsewhere and was captured by Earth's gravity as it passed |
Impact theory | Most accepted, large impact knocked a large quantity of material from Earth |
