Inside The Earth

  1. 1. Inside the Earth<br />
  2. 2. The Composition of the Earth<br />Crust<br />Mantle<br />Core<br />
  3. 3. The Crust<br />The crust is the outermost layer of the Earth.<br />It is the thinnest layer of the Earth<br />Two types of crusts<br />Continental <br />Oceanic<br />
  4. 4. Continental Crust<br />Made of light substances<br />Silicon <br />Si<br />Oxygen<br />O<br />Aluminum<br />Al<br />
  5. 5. Oceanic Crust<br />Contains heavy substances<br />Iron<br />Fe<br />Calcium<br />Ca<br />Magnesium<br />Mg<br />Because it contains heavier substances it is denser than the continental crust.<br />
  6. 6.
  7. 7. The Mantle<br />The mantle is the layer of the Earth between the crust and the core.<br />The mantle is very thick<br />Contains most of the Earth’s mass<br />No one has really seen what the mantle looks like.<br />The Ocean floor gives us many clues about the mantle<br />Underwater Volcanoes<br />
  8. 8. The Core<br />The core is the layer that begins at the bottom of the mantle and ends at the center of the Earth.<br />The core is made mostly of Iron<br />There is a Inner and Outer Core<br />
  9. 9. Inner and Outer Core <br />The outer core is the liquid layer of the earth’s core.<br />The inner core is the solid, and dense center of the planet.<br />
  10. 10. Earth’s Core<br />
  11. 11. The Physical Layers of the Earth<br />Lithosphere<br />Greek for “Rock Sphere”<br />Divided into pieces called tectonic plates<br />Made up of the crust and the rigid upper part of the mantle.<br />Asthenosphere<br />Greek for “Weak Sphere”<br />Lies between the Lithosphere and Mesosphere<br />Made of solid rock<br />Mesosphere<br />Greek for “Middle Sphere”<br />Lies between the Asthenosphere and the Earth’s Core<br />
  12. 12. Earth’s Physical Layers<br />
  13. 13. Temperature and Pressure increase as you move towards the center of the Earth.<br />Plasticity is a solid that has the ability to flow.<br />Convection currents are hot material that becomes less dense and rises while cooler material becomes denser and sinks.<br />This occurs in mantle layer of the Earth.<br />
  14. 14.
  15. 15. Mapping the Earth’s Interior<br />Scientist use Earthquakes to find out information about the interior of the earth<br />Seismic waves are vibrations produced by earthquakes<br />The waves traveling speed determines the Earth’s density.<br />Seismographs are used to measure the travel times of the waves<br />
