Science -south carolina landforms power point

  1. 1. South Carolina LandformRegions(and facts about Landforms)SC
  2. 2. Where is South Carolina?Here we are!SouthCarolinaborders theAtlanticOcean.North AmericaUnited States of AmericaEarthSC
  3. 3. South Carolina Landform RegionsMapDo you remember your 3rdgrade South Carolina LandformRegions? Can you name these?Our state isdivided intoregions,starting at themountains andgoing down tothe coast.SC
  4. 4. Did You Know?Virginia, North Carolina, South Carolina, GeorgiaThe Southern Atlantic States have about the sameregions as we do in South Carolina.So, during this study, you will also hear about otherstates. What you hear about that landform region inVirginia, for example, is much the same in South Carolina.
  5. 5. Blue Ridge MountainsLandformRegionsThe Blue RidgeMountain Regionis only 2% of theSouth Carolinaland mass.SC
  6. 6. Facts About the Blue RidgeMountains . . .1, The Blue Ridge Mountains are part of theAppalachian Mountain Range.2. Many streams begin in the mountains.3. These are the oldest mountains in America.4. The Blue Ridge Mountains are FoldingMountains.5. The Blue Ridge Region takes up only 2% ofSouth Carolina’s land mass.
  7. 7. Types of MountainsThere are four different types ofmountains:Folded MountainsUpwarped MountainsFault Block MountainsVolcanic Mountains
  8. 8. Folded MountainsFolded mountains form when rock layerssqueezed from opposite sides buckle andfold. The Appalachians, or Blue RidgeMountains are Folded mountains.Types of Mountains
  9. 9. Blue Ridge Mountains, SC
  10. 10. Upwarped MountainsUpwarped mountains form when crust ispushed up by forces inside of the Earth.Examples: Southern Rocky Mountains andAdirondack MountainsTypes of Mountains
  11. 11. Adirondack Mountains,NYYes! There are really mountains in the state ofNew York!
  12. 12. Fault Block MountainsFault-block mountains are made up of hugetilted blocks of rock which are separatedfrom surrounding rock by faults.(Examples: Grand Tetons and Sierra Nevada Mountains.)Types of Mountains
  13. 13. The Tetons
  14. 14. Volcanic MountainsVolcanic Mountains are cone-shapedmountains created from pile-up ofmolten materials.(Examples: The Cascade Mountains in Oregon and Washington,and the Hawaiian Islands.)Types of Mountains
  15. 15. Mt. Ranier, WashingtonMt. St. Helens, WashingtonThe water in Crater Lake, Oregonis just this blue!The Cascades is a volcanicmountain range in theNorthwestern United States.Crater Lake,Oregon—seethe coneisland in thewater.
  16. 16. PiedmontLandform RegionsIf you could see thePiedmont Region fromspace and without thefoliage, you wouldnotice it is sort of ahuge plateau.SCGreenville Spartanburg Union Greenwood Rock Hill Abbeville
  17. 17. Facts About the PiedmontRegion . . .1.The Piedmont is the largest region ofSouth Carolina.2. The Piedmont is thought to be a largeplateau (raised high land that is usuallyflat on the top).3. The Piedmont is NOT flat, but is hilly.4. The Piedmont contains many of ourlargest cities in South Carolina.5. The Piedmont is often called TheUpstate.
  18. 18. What do we know about thePiedmont of the SoutheasternAtlantic States?Let’s watch a three minute video showing usabout the Piedmont.You will look for information about the “fall line”that divides the higher Piedmont region fromthe lower, softer, Coastal Plain region.You will find out how early pioneers used therivers and waterfalls to their advantage.
  19. 19. What do we know about thePiedmont Region of ourSoutheastern States?The Piedmont of the SoutheasternStates, StreamlineSC
  20. 20. Movie Follow-UpWhat IS the fall line?How did the fall line hurt transportationin the early years of our country?What did the settlers build at the fall lineso they could use the power from thefalls?
  21. 21. Sandhills LandformRegionsDo you wonder whythe Sandhills are sosandy? They used tobe the coastline ofNorth Americamillions of years ago.SCColumbia, Our State Capitol
  22. 22. Four Facts About the SandhillsRegion . . .1. The Sandhills are covered with the leftover sand dunes when it was SC’scoastline millions of years ago.2. The Sandhills are next to the fall linewhere the land slopes down and therivers become waterfalls.3. The Sandhills are hilly.4. The Sandhills has softer ground thanthe Piedmont.
  23. 23. How are sand dunesformed?All sand dunes are formed the same way.Every single one is a pile of sand built upby the wind. Once the sand has beenpicked up by the wind, it will gowherever the wind carries it. Eventhough most sand dunes are made of thesame material and formed in the sameway, they vary widely in appearance.
  24. 24. Coastal PlainLandform RegionsThere is an Inner andOuter Coastal Plain.Can you see thedividing line? This areawas once in the oceanmillions of years ago.SCAiken Orangeburg Sumter Florence
  25. 25. Facts About The Coastal Plains1. The Coastal Plains are very wet.2. The Coastal Plains used to be under the oceanmillions of years ago.3. The Coastal Plains have savannahs, which arewild grass prairies.4. The Coastal Plains have a lot of swamps andmarshlands.5. Because of sediment that settled in the oceanmillions of years ago over the Coastal Plains,there is a lot of Sedimentary Rock in this area.6. The Coastal Plains are flat in most areas.
  26. 26. What is sediment?Sediment (n.) Material that settles to thebottom of a liquidWhat kind of sediment settled in the Inner andOuter Coastal Plains millions of years agowhen they were covered with oceans?This sediment forms layers of rockcalled Sedimentary Rock.
  27. 27. What Happened?What happened to all that sedimentary rock thatis supposed to be in the Inner and OuterCoastal Plains?The coastal plains are fairly flat, so the rock hasthat eroded over the last million or so yearshas stayed in the same place as soil instead ofwashing away. There is no new rock exposedfrom erosion, so you do not see sediment!Don’t you think the sediment must haveeroded into soil along time ago?
  28. 28. Flat?Another thing about the Coastal Plains—Geologists have learned that the coastalplain stair-steps down gradually with sixflats and seven slopes. They believe thatthis happened as the ocean receded(moved backward) throughoutthousands of years.
  29. 29. Coastal Zone LandformRegionsTake a look at thecity map of SouthCarolina. You canname the cities inthe Coastal Zone.SCHilton Head Beaufort Charleston Georgetown Myrtle Beach
  30. 30. Facts About the Coastal Zone1. It borders the Atlantic Ocean.2. It has sand dunes.3. It has marshlands, inlets, bays, barrierislands.4. It had Palmetto and Palm trees.5. It has beaches.6. It is often battered by hurricanes.
  31. 31. How Did Pioneers Use theCoastal Zone?What did the pioneers grow in the CoastalZone? Why did they grow this crop?Watch a one-minute video to find out.
  32. 32. StreamlineSC VideoName a way that pioneers used theCoastal Zone of South Carolina.Along the Southern Coastline, StreamlineSC
  33. 33. Movie Follow-UpWhat crop DID the settlers grow in theCoastal Zone?Why was this crop grown in this region?
  34. 34. How did cities begin inSouth Carolina?Take a look at the South Carolina CitiesMap to learn where the main cities areplaced. Then look at the Rivers andStreams Map. Can you see learnanything by comparing the two maps?Hint: How were rivers used when theSouth Carolina colony was beginning tosettle?
  35. 35. South Carolina CitiesMap
  36. 36. SC Rivers
  37. 37. Remember . . . There are five landform regions inSouth Carolina: Blue Ridge Mountains Piedmont Sandhills Inner Coastal Plain Outer Coastal Plain Coastal Zone
  38. 38. South Carolina 5thGrade Science CurriculumStandardStructure of the Earth’s System Locate and describe the characteristics of South Carolinalandform regions such as Blue Ridge, Piedmont, Sandhills,Coastal Plains, and Coastal Zone. Define constructive forces, which include crustal deformation(folding and faulting), volcanic eruptions, and deposition ofsediment.) Describe how landforms are created as a result of constructiveforces.
