1Chapter 1 Bell Work Grab textbook, Nystrom atlas and folders Pick up Unit 1 Checklist and outline mapFill out Ch. 1 on outline map w/colored pencils “You may only be someone in the world, but to someone else, you may be the world.”
2Map Concepts: pg.10 Compass Rose Map Legend- Scale directional indicator that shows the Cardinal Directions on a mapCardinal directions are north, south, east, and west.Map Legend-Or KEY, tells reader about the symbols used in that mapExample: Page 10; what do red lines mean?Black crossed lines?ScaleTells the reader about the size of a map in relation to the size of the real world.Which map on page 10 shows a more detailed map?The one on the right b/c the mile scale is smaller.
3Map Concepts: pg.10 Map Types (3) Physical: Shows physical features like mountains, rivers, lakes of an areaPolitical- shows political features, things determined by people! State/nat’l boundariesWhat is capital of Iran of pg. 14Special purpose: designed to show specific data; labeled what they show
4Map Concepts: pg.10 Hemispheres: means half of a sphere When divided along the equator the earth is split into two? What would they be called?North/South HemispheresWhen divided along the Prime meridian what would they be called?East/West Hemispheres
6Back Special Purpose What is this a map of? Climate mapWhere is a majority of the Temperate?SoutheastWhat does the dark red represent?EquatorialBack
7Latitude/Longitude Latitude Longitude Also called parallels bc they run parallel to the equatorRun east to west, measured north and southLongitudeAlso called meridians; run from pole to poleRun north to south, measured east to west
8Anchor Work Get Worksheets Finish as much as can! With your 9 o’clock partners begin working on them for tomorrowWhen finished or with a minute to go in class make sure to load them up in your folders and put everything back neatly!!Have a great day! Be diligentFinish as much as can!
9Bell Work: Brinnnnggg, Bringggg Get books, foldersSit w/3 o’clock partnersEvery group to come back to me w/the 3 CORRECT answers the 1st time gets a prize!!Using the text pages 16,17, and 22 Answer7 North, 2 East60 north, 11 East42 north, 19 eastLome, TogoOslo, NorwayTirane, Albania
10GEOGRAPHYWhat is it?Study of where people, places, and things are located and how they relate to each otherTechnology: Read/define these 4 concepts from pages 35-37SonarRemote SensingGPSGIS
11Technology Sonar Remote sensing (satellites) Analyzes sound to determine distance/directions. Used to study ocean floorRemote sensing (satellites)Compares older/newer images of regions to identify changes in land use, vegetation, growthGPS: Global positioning systemUses satellites to broadcast accurate time measurements on distance and locationGIS: Geographic Information systemsComputer technology to solve geographic problemsLike where to put a nuclear power site b/c it could show what type of area could handle it
125 Themes of Geography5 Important ?’s that geographers use to help them organize info about the worldLocation: 2 typesAbsolute: exact position of a placeLatitude and LongitudeRelative: Location of a place described by its relation to another placeExampleGrand Island is around 100 miles west of Lincoln as the next major city west near the Platte river
135 Major Themes of Geography 5 Important ?’s that geographers use to help them organize info about the worldPlace: consists of a places physical and human characteristics (2 types)Helps geographers show the distinctness and similarity of one place to anotherPhysical: every place has unique physical aspects like landforms, ecosystems, and climate to help separation from other placesHuman Characteristics: How many people live, work, or visit there? What are languages, customs, beliefs? How are they governed? How does their economy work?
14Lesson Closing Tying in the 1st 2 themes of Geography w/6 o’clock partnersCut out picture of magazine article (nat’l geog. In back)Find 2 pictures and list each thing for their location and their placeExample: if I found a picture of chimney rockI could give its absolute and relative locationI could give a physical and human characteristic of the placeWill need to explain tomorrow
15Bell Work Get Books and folders Answer questions What is the absolute and relative location of Denver and Detroit?What are 2 of 4 ?s geographers ask for Human characteristics?What are the two characteristics of a place?What are the two types of location?
16Themes of Geography Review Location: Has both absolute (lat/long.) and relativePlace: consists of a places physical/human characteristics
17Themes of Geography Regions: (3 types) Group of places w/at least one common characteristicCan be determined by physical/human characteristicsOr by people’s perceptionFormal: certain characteristics found throughout areaEx: states, countries, cities all political regions, cornbeltFunctional: consists of a central place and the surrounding areas effected by itAmazon drainage basin: drained by Amazon river so it effects the entire regions rivers and tributariesPerceptual: defined by people’s feelings/attitudes towards an areaU.S. regions like upper midwest and middle statesMexico is another b/c they are part of N. America but often linked w/ S.America b/c of their similar culture/norms
18Themes of GeographyMovement: b/c places have different characteristics;people, places, goods, and ideas will move between themRead movement section on pg.41 and apply to these (History of New Orleans)1700sMajor French port that shipped goods from Mississippi to ocean1800sRR expansion cut down the river trade importance1900sCities importance limited to surrounding states, became a major tourist hub and important center for oil/gas
19Themes of Geography Human-Environment Interaction Concerned with……. How people use their environmentHow they have changed itWhat are the consequences of those changes?How have they responded to those changes?Example:American SW had few residents before technology made it capable to increase habitationRapid growth in population is now putting a strain on water supply and other areas
20Anchor Activity Grab colored paper and 1-2 Markers Create a concept map over the 5 themes of Geography, using as little of your notes as possibleList the themes as well as the main concept w/in each themeExample: Region= definition, and 1-3 typesKeep in foldersFinish Picture activity from TuesdayVideo
21Bell Work: 10 minutes Get book and folders Finish Concept Map and completion check by me (keep in maps)You and your partner, Find at least the absolute location of the two pictures you took out of the nat’l geo!NO ONE SHOULD TAKE A BOOK OUT OF ROOM W/OUT PERMISSION; IF YOU SHARE IT

Of people, goods, ideasN.Orleans ExampleHuman/Environment InteractionHow have people changed environment?How have they dealt with those changes?
23Changes within the Earth Section 2Changes within the Earth
24Physical Characteristics Geology: Study of the earth’s physical structure and historyDivided up into 2 main AreasEarth’s LayersLand/Air/Water
25The Earth’s Layers Core (Center) Mantle- around the core Consists of very hot metal, mainly iron mixed with some nickel.Inner Core- is thought to be dense and solidOuter Core metal is molten, or liquidMantle- around the coreThick layer of rock, est. to be 1,800 mi. thickRock is mostly solid but some upper levels may be more flexible
28Lesson ClosingFinish any activity that is in your folder that is not doneWe will be speeding up the process in the next few weeks!!Finish Video while workingStay Quiet
29Differentiated Friday Watch 20 Minute VideoPhysical Features of Earth25 Minutes of Work time on projects
30Bell Work Grab books and folders Be ready to answer questions about earth’s layers?What is the center of the earth that is mainly iron mixed with some nickel?CoreWhat is the thinnest rocky layer?CrustThe pit of the peach?Inner CoreUp to 1800 miles thick and the biggest of the layersMantle
31Land/Air/Water Divided into spheres by various physical forms LithosphereSoils, rocks, landforms, and other surfacesAtmosphereLayer of air, water, and substances above the surface
32Land/Air/Water (cont’d) HydrosphereWater in oceans, lakes, rivers, and even under the ground….called a ?AquiferBiosphereIs the world of plants, animals, and other living things that occupy the land/water of the earth
33Land/Air/Water Large landmasses in the oceans are called? ContinentsHow many Continents are there?7, N.America, S. America, Asia, Europe, Africa, Australia, and AntarcticaWhat is the smallest?AustraliaBiggest?Asia
34Landform Classifications Classified according to differences in reliefReliefThe difference in elevation bt. The highest and lowest pointsWhether they rise gradually or steeplyMajor types of LandformsMountains, hills, plateaus, and plains
35How are The 4 different Mountains Hills Plateau Plain Rise at least 2000 ft above surrounding terrainHillsLower, rounded, and generally less steepPlateauRaised Area, but surface is generally levelPlainFlat or gently rolling area w/few elevation changes
36Physical Processes What are the forces that shape an area Two major types:Volcanism (movement of magma)Movements affecting the earth’s crust.
37Volcanoes Can have three types: Most famous is distinctive cone like Mt. Fuji in JapanFrom alternating explosive eruptions and smooth lava flow.
38Movements in the Crust Plate Tectonics Theory: Theory that the earths outer shell is not one solid sheet of rock.Instead broken into a number of moving plates varying in size and thicknessSlide/move over a hot/flexible layer of the mantle; helps explain earthquakes/volcanoes
39Continental Drift Theory Theory that continents were once joined together in a super-continentThe continents slowly shifted positions due to their movement on what????Their tectonic plates
40Lesson Closing Work on Section 2 Guided Reading/Review Read Plate Tectonics and Continental DriftAnswer Question to caption on pg. 47Moving east/west towards each otherVolcanoes/TornadoesWork on Section 2 Guided Reading/Review
41Bell Work Look at two Theory Questions What was done to support the continental drift theory?Wegener found identical fossils from various continentsList the three volcanoes types given by the bookSmall cinder cone, distinctive cone mtns., plateau likeAnswer questions to caption on pg. 48Bt. 135 million and 65 million years agoLaurasia and Gondwana
42Seafloor Spreading Another theory supporting Plate tectonics Using Sonar Scientist began to see that the ocean floor had similar land formations as the continents did. But that rocks were much youngerTheory stated that molten rock came up beneath the underwater ridge system, broke through a split at the top.The new rock spreads out both ways as if on a conveyer belt.
44Plate Movements Convection Circular movement caused when a material is heated, expands and rises, then cools and falls.
45When Plates Meet 4 Major Types of Plate movement Spreading Spreading, Subduction, Convergence, FaultingSpreadingWhen plates pull away from each otherForm a diverging plate boundaryLikely to have rift valleys, earthquakes, or volcanic action
46When Plates Meet Cont’d Outcomes when plates meet depends on the density of those platesOceanic plates (ocean) are denser than continental platesSubduction- when an oceanic (denser) plate meets a continental plate it slides beneath the lighter plate.Ocean material will sink/melt; some coming back up in volcanic action before it coolsCascade Range/Andes Mountains were formed by this.
47ConvergenceWhen two oceanic plates collide the denser will slide beneath.Can form an arc of volcanic islandsWhen two continental plates collide, NEITHER will sinkBuckling, folding will result in great Mountain ranges.
48Faults When plates slip or grind past one another Ring of Fire Example is the San Andreas fault in CA.Ring of FireCircle of volcanoes surrounding the pacific ocean, look on pg. 47.
49Lesson Closing Activity With 6 o’clock partners you will be given two vocab. Words that you need to draw clues on the board for other teams to answer!Will Draw tomorrow
50Bell Work Finish Game: Draw clues on board Answer these questions Write down this assignment for Thursday and will start at end of period!Pg. 581-16, 18-19Time to work on Thursday!!
51Review What are the 4 main sphere’s? And describe Hydrosphere, Biosphere, Lithosphere, AtmosphereWhat are the Earth’s 3 main layers?Core, Mantle, CrustWhat are the four major types of plate movement, and describe them?Spreading-plates moving away from each otherSubduction- oceanic plate going under continental plateFaulting- Plates sliding/grinding past one anotherConverging- Similar plates colliding with each other
52Changes on the Earth’s Surface Section 3Changes on the Earth’s Surface
53Review Last Section We talked about what? How internal Forces change the earthLike convection, subduction, continental drifting ect.This section will be focused on how external forces of the earth are affecting its appearance
55Changes on the Surface Weathering The breakdown of rock at or near the earth’s surface into smaller and smaller pieces.Two Main types:MechanicalChemical
56Mechanical Weathering Occurs when rock is actually broken or weakened physicallyBreaks large masses of rock into boulders, stones, pebbles, sand, and even dust.Frost Wedging: Most common typeWhen water freezes into ice in a crack in rockWater expands when frozen and slowly widens the crackEver frozen a can of pop?Another type is when seeds rook in rock cracks
57Chemical WeatheringProcess of altering a rock’s chemical makeup by changing the minerals that form the rock, or by combining them with new chemical elementsImportant FactorsWater and Carbon DioxideWater/Carbon DioxideCombined form a carbonic acid that can dissolve certain rock (limestone)Ex.: CavesType: Chemical RainCan destroy forests/water as well as eat surfaces of stone buildings/rock formations.
58Erosion Most common Causes Erosion Water, Wind, Glacier The movement of weathered materials such as gravel, soil, and sand.
59Water Erosion Moving water is greatest cause of erosion. Sediment: Small particles of soil, sand, and gravel carried by rivers/streams. Acts as sandpaper to rock surfaces
60Wind Erosion Second major cause of erosion Loess: Wind-blown deposits of mineral-rich dust and silt.Sandstorms are one major cause of erosion.
61Glacier Erosion Glaciers: Huge, slow-moving sheets of ice As they move they carry dirt, rocks, and boulders along their bottom edgeThe terrain is worn away by the debris dragging along with the iceMorainesRidge-like piles of rocks and debris left behind by melted Glaciers.
62Questions What are the 3 main types of erosion? Why is erosion important?Why is sediment important?Where is wind erosion especially important?What are some reasons its importantPg. 581-16, 18-19Time to work on Monday!!
