Landforms of the Earth

  1. 1. Anna Mae T. Cayanan BEED2-A
  2. 2. What is LANDFORM? • A landform isa naturalfeature of the Earth'ssurface. • 2 Processes thatare responsible in the changes and formation of landforms: ENDOGENOUSPROCESSES EXOGENOUSPROCESSES
  3. 3. ENDOGENOUS PROCESSES • Endogenousprocesses are processes thathappen beneaththe Earth such as faulting,folding and volcanic activities. • Endogenousprocesses cause many majorlandformfeatures.
  4. 4. FAULTING, FOLDING AND VOLCANIC ACTIVITIES
  5. 5. EXOGENOUS PROCESSES • Exogenousprocesses are those thathappen on thesurface of theEarth. • 3 mainexogenous processes are:  Weathering Erosion  Deposition
  6. 6. The differentlandformsof the Earth could be categorized into three based on theirsize, magnitude and relieffeatures. Relief means highest/ lowest elevationpoints in an area.
  7. 7. Categories of according to
  8. 8. First Order of Relief Those are big and vast like the continentand ocean basins. SecondOrder of Relief Those found on thecontinentsand ocean basins. Examples: mountain,volcanoes and plains
  9. 9. The mountainsystems found on thecontinents. The landforms that are foundunder the oceans.
  10. 10. ThirdOrder of Relief The landformsthathave been formedby differentexogenous processes through the differentagentsof erosion. • LEFT-OVERS This meansthattheerosionalforces or the differentagentsof erosion degrade themountains,plateausandother featuresby weatheringthemandcarrying the weatheredsedimentsto the other places wheretheyare depositedto formanother landform.
  11. 11. • The features that have been eroded are referred to asresidual landformsand those that have been accumulated are called depositional landforms. • Examples of residuallandforms: Rivervalleys Canyons • Examples ofdepositional landforms: Deltas Sand Dunes Sandbars Moraines

  15. 15. Major
  16. 16. 4 MAJOR LANDFORMS PLAINS • A plain is wide stretchofflat land. This is suitablefor planting various crops like rice and corn. Usually, people build their homes and establishsettlementswith governing bodies in the plain.
  17. 17. PLAIN OF CENTRAL LUZON
  18. 18. PLAIN OF NEGROS OCCIDENTAL
  19. 19. 4 MAJOR LANDFORMS Mountain A mountain isa large landformthat stretches above the surroundinglandin a limited area, usuallyin the form of a peak. A mountainis generally steeper than ahill.

  22. 22. MOUNTAIN
  23. 23. 4 MAJOR LANDFORMS Plateau • A plateauisan elevatedplainor a relativelylargeflatareathat standsabove thesurrounding land.It risesfrom 90tomore than 900meters(300 to3000 ft).This is suitablefortendinganimalsas thetemperaturehereiscool. Itis alsoidealforplantsthatdo not needmuch water.
  24. 24. BUKIDNON PLATEAU PLATEAU
  25. 25. PLATEAU DECCAN PLATEAU TIBETAN PLATEAU
  26. 26. 4 MAJOR LANDFORMS Hills • It is a land thatrises (less than 300 meters)above itssurrounding andhas a rounded summit.A hill is a land formationthatis smallerandlessruggedthana mountain.
  27. 27. CHOCOLATE HILLS HILLS
  28. 28. Minor
  29. 29. 4 MINOR LANDFORMS • VALLEYS- A valley is a low area between hills/ mountains, often with a river running through it. • POLOLU VALLEY in HAWAII
  30. 30. CAGAYAN VALLEY
  31. 31. NAPAVALLEY in CALIFORNIA
  32. 32. 4 MINOR LANDFORMS BASINS • A basin is a hollow ordepression in Earth's surface with no outlet for water. This means that any water that originates in orflows into a basin does not escapeit. A basin can be approximately circular,resembling a bowl, orit can be oval-shaped. It can be a small structure, measuring only a few miles in diameter. Often, it is much larger. Abasin is usually surrounded mostly by higher land. Depending on where it is located, a basin may sometimes include desert areas, which arearid ordry regions receiving less than 10 inches (25 centimeters) of rain per year.
  33. 33. GREATBASINOF UTAH
  34. 34. The Great Basin stretches through more than 200,000 square miles in Nevada and Utah.
  35. 35. 4 MINOR LANDFORMS • BUTTES- A butte is an isolated hill with steep, often vertical sides and a small, relatively flat top; buttes are smaller than mesas and plateaus.
  36. 36. Mittens and Merrick Butte in Monument Valley Arizona
  37. 37. BUTTES OF THE CROSS, UTAH
  38. 38. 4 MINOR LANDFORMS • CANYONS- A deep narrow valley with a steep sides, oftentimes with a stream flowing to it.
