  1. Earth and Space Science Review 2013-2014

  2. Weather/Meteorology • Climate – pattern of weather in alargearea over a long period of time 2. Weather – condition of the atmosphere in a smaller area over a shorter period of time

  3. Climate patterns

  4. 3. Types of heat: • Radiation = how sun’s heat travels to us through space • Conduction= heat is transferred by contact (soil in beaker warms from outside in) • Convection = heat rises in one area and sinks in another; the air masses replace each other. (hot airrises, cold airsinks)

  5. 4. Equatorial zones that receive mostdirectsunlight = hottest.

  6. 5. Cloud formation –Waterevaporates into the air (water vapor) then rises, cools, andcondensesonto dust particles in the upper atmosphere. Clouds are millions of tinywaterdroplets combined together.

  7. 6. Rain Shadow - More precipitation on mtns b/c it is colder, so more condensation.

  8. 7. Convection current – air moving in acircular pattern caused byuneven heating of Earth.

  9. Remember these?!

  10. 8. Weather front – boundary between twoairmasses (where changes in weather occur) Types: stationary, cold, warm, etc.http://www.classzone.com/books/earth_science/terc/content/visualizations/

  11. 9. Water cycle:http://earthguide.ucsd.edu/earthguide/diagrams/watercycle/index.htmlhttp://www.enchantedlearning.com/subjects/astronomy/planets/earth/Watercycle.shtml Evaporation Transpiration Condensation Precipitation Run-Off Filtration Accumulation Sublimation

  12. http://earthguide.ucsd.edu/earthguide/diagrams/watercycle/index.htmlhttp://earthguide.ucsd.edu/earthguide/diagrams/watercycle/index.html http://www.enchantedlearning.com/subjects/astronomy/planets/earth/Watercycle.shtml 9a. Evaporation = water moves fromliquidtogasstate; heatgained b. Condensation = water moves fromgastoliquidstate; heatlost c. Sublimation = water moves fromsolidtogasstate; heatgained

  13. Astronomy/Space Science –Earth-Moon-Sun System 1. Seasons – summer = axis tiltstowardsun, winter = axis tiltedawayfrom sun.

  14. 2. Moon Phases – new/can’t see full/see whole side waxing = getting bigger waning =getting smaller gibbous crescent http://www.moonconnection.com/moon_phases.phtml

  15. 3. Eclipses a. Solar =Sunblocked out (caused by shadow ofmoonon Earth), only seen from certain places on Earth http://www.mreclipse.com/Special/SEprimer.html b. Lunar =moonblocked out (caused by shadow ofEarth on moon) Seen from everywhere on Earth http://www.mreclipse.com/Special/LEprimer.html

  16. 4. Rotation – Planetspinson its axis = 1 day (24 hrs), same length all over the world Revolution – one completeorbitof planet = 1 year, same length all over the world, 365 days

  17. Universe, Galaxy, Solar System • Planet – orbits astar Moon – orbits a planet (also called a satellite) 2. Star – gaseous ball of fire. How many in our solar system?ONE: the sun!

  18. 3. Dwarf planets = Ceres, Pluto, Haumea, Makemake, Eris

  19. 4. Inner planets –Mercury, Venus,Earth, Mars Outer planets - Jupiter,Saturn, Uranus,Neptune

  20. 5. AsteroidBelt – big space rocks between Mars and Jupiter 6. KuiperBelt – region beyond Neptune that is full of comets, asteroids and other debris.

  21. 7. Comets – have a tail, made of ice, orbit theSunhttp://www.kidsastronomy.com/comets.htm

  22. 8. Meteor - when space rock enters atmosphere Meteorite - space rock Meteoroid - when it hits E’s surface

  23. Biggest item Universe Galaxy (Milky Way) Solar System Planet Satellite Smallest item

  24. Geology 1. Rock Cycle – melting/cooling, heat/pressure, compaction/cementation

  25. Weathering –breaks downthe rock Erosion –movement of rock particles Rock Cycle Diagram: http://www.learner.org/interactives/rockcycle/swfs/diagram.swf Go to Barb’s website and click “geology links”

  26. Three Types of Rocks Igneous = Volcanic intrusive or plutonic: from magma, ex. granite, large crystals extrusive or volcanic: from lava, ex. obsidian, basalt

  27. Sedimentary clastic: layered, deposition ex. Sandstone chemical: crystals from evaporation of water, stalactite, stalagmite ex. thunderegg organic: fossils buried in layers of sediment

  28. Metamorphic – (gumdrops/gummi bears) ex. gneiss, slate Foliated: flattened crystals Non-foliated: mangled/folded, or just a completely different rock altogether

  29. Geologic Time Scale

  30. Finding relative ages of rocks = comparing which one is older a. Law of Superposition - helps determine relative ages of rocks b. Index fossils – organisms that lived for a relatively short time and are common in the fossil record. c. Carbon dating (C-14) – helps determine age of organic remains

  31. Earth Science – Plate Tectonics • Earthquakes – seismic waves (P and S) are the energy released from the earthquake’s focus. P-waves travelfasterthan S-waves.

  32. Seismographs are the instruments that record the seismic waves. • Richter Scale – measures the energy release of a moderate earthquake (magnitude 3.0-7.0) • Moment magnitude - measures the energy release of largescale earthquakes • Mercalli Intensity scale – measures the damage done by an earthquake.

  33. Focus vs. epicenter

  34. 2. Inner Earth– crust,mantle(plastic,) outer core (liquid,) inner core (solid)

  35. 3. Volcanoes – shield, composite/stratovolcano, cinder cone
