Earth's Sphere's, Interior & Continental Drift - Nazar

  1. 1. Earth Interior is a part ofthe earth beneath the crust Lithosphere is the outer part of the earth Hydrosphere is the waters of the earth’s surface Atmosphere is mass of air surrounding the earth
  2. 2. LayersOceanic Crust is land underneath the oceanContinental Crust is rocky outer layer of EarthMantle is thick layer and is made up of melted rockOuter Core is 2,250 km thick and is completely liquidInner Core is solid and is made up of nickel and iron
  3. 3. SummaryThere are three major types of the earth interior types:atmosphere, hydrosphere, lithosphere.Earth is divided in different parts called layers. Outerlayer of the earth has continental and oceanic layers.Underneath these crusts there’s a mantle, liquidmagma. Underneath the mantle there’s a outer core,total liquid. Mantle and outer core are both liquid butthey never mix. And last deepest layer is inner core andis solid made of metal.
  4. 4. Questions What are the layers of earth interior? Where are the layers located?
  5. 5. Continental DriftContinental Drift is a theory that all thecontinents had formed one landmass beforebreaking apart and drifting to their presentlocations.
  6. 6. This landmass was called Pangea. The theory wasbrought by Alfred Wegener in 1915.
  7. 7. Evidence #1 Puzzle
  8. 8. Evidence #2 Fossils
  9. 9. Evidence #3 Landforms
  10. 10. SummaryContinental Drift is a theory that all the continents weretogether. This theory was brought by Alfred Wegener in 1915.There are three types of evidence that support Alfred’stheory.#1 Puzzle#2 Fossils#3 Ladnforms
  11. 11. Questions What is Pangea? What are the evidence supporting Continental Drift Theory
