  1. WHICH FORCES SHAPE THE SURFACE OF THE EARTH?

  2. Conceptual Basis of Second Half of Course EARTH’S SURFACE

  3. EXTERNAL FORCES Sun

  4. EXTERNAL FORCES Sun Wind Precipitation Hot/Cold Glaciers Rivers Waves

  5. EXTERNAL FORCES Sun Wind Precipitation Hot/Cold Glaciers Rivers Waves DRIVEN BY ENERGY STORED WITHIN THE EARTH FROM THE TIME OF ITS CREATION INTERNAL FORCES

  6. EXTERNAL FORCES Sun Wind Precipitation Hot/Cold Glaciers Rivers Waves Volcanoes Mountain Building Earthquakes Subduction INTERNAL FORCES

  7. EXTERNAL FORCES > INTERNAL EARTH’S SUFACE FLAT LANDSCAPE WITH LITTLE VARIATION IN RELIEF: FEW HILLS AND SHALLOW VALLEYS

  8. EXTERNAL EXCEED INTERNAL! Nullarbor Plain, Australia Jos Plateau, Nigeria Saskatchewan, Canada Florida! Steppes, Asia North European Plain

  9. INTERNAL FORCES > EXTERNAL HIGHLY VARIED LANDSCAPE WITH HIGH VARIATION IN RELIEF: MOUNTAINS, DEEP VALLEYS.

  10. INTERNAL EXCEED EXTERNAL! Mount Rainier, WA. Snowy River, Australia. Lake Tanganyika, Africa Jos Plateau, Nigeria Port au Prince, Haiti North Marianas, Pacific Mt. Vesuvius, Italy

  11. WHY MOUNTAINS?

  12. WHY OCEANS - SHALLOW?
