  1. Constructive & Destructive Forces Shaping the Earth's Landscape

  2. Constructive & Destructive Forces Constructive Force *Forces that CREATE features on the Earth's surface Destructive Force *Force that CHANGES Earth's surface

  3. Constructive ForcesEssential Questions • What are surface features? • What are examples of constructive forces? • How can a surface feature be changed by a constructive force? • What are surfaces features caused by constructive forces?

  4. Constructive Force • Deposition – • a process of dumping sediment, dirt, rocks, or particles in on place.

  5. Constructive ForceEssential Questions • What are surface features? • Surface features are landforms and bodies of water that cover the Earth’s surface such as: • Mountains, valleys, canyons, gorges, beaches, sand dunes, barrier Islands, flood-plains, moraines, volcanoes, oceans, lakes, and rivers

  6. Constructive ForceEssential Questions • What are examples of constructive forces? • Deposition • Volcanic Activity • Earthquake Activity • Faulting • Folding

  7. Constructive ForceEssential Questions • How can a surface feature be changed by a constructive force? • By natural forces such as wind, water, ice, through the process of deposition. • The movement of the Earth’s crust • Plate Tectonics

  8. Constructive ForceEssential Questions • What are surface features formed from constructive forces? • Delta • Floodplains • Barrier island • Sand dune • Moraine • Islands • Mountain Ranges • Cliffs

  9. Destructive ForcesEssential Questions • What are examples of destructive forces? • How are surface features changed by destructive forces? • What are examples of surface features caused by destructive forces?

  10. Destructive ForceEssential Questions • What are examples of destructive forces? • Weathering • Mechanical / Physical • Chemical • Erosion • Volcanic Activity • Earthquake Acuity

  11. Destructive ForceEssential Questions • How are surface features changed by destructive forces? • Freezing and thawing of the earth’s crust • Freezing water in cracks of rock • Oxidation / rusting • Carbonic acid / acid rain • Impact of organisms • Water / rivers and oceans • Ice / glaciers • Wind • Gravity • Movement of earth’s plates / plate tectonics

  12. Destructive ForceEssential Questions • What are examples of surface features caused by destructive forces? • Caverns / Carbonic Acid • V-shaped valleys / River water • Canyon / gorges / River water • Sea arches / Ocean Waves • Sea stacks / Ocean Waves • Buttes / Wind • Desert pavements / Wind • Reshaped mountains / Volcanoes • Trenches / Earthquakes
