2 Indirect evidence from seismic waves 1. What are the 2 main types of evidence that geologists use to learn about Earth’s Interior?Direct Evidence from Rock SamplesIndirect evidence from seismic waves
3 2. What is pressure?Pressure results from a force pressing on an area.
4 3. What causes the Earth’s magnetic field? Scientists think that the movements in the liquid outer core create Earth’s magnetic field.
5 4. Directions: Label the layers of Earth by writing the name of the layer in the blank.
6 5. The deeper down inside Earth, the greater the pressure. True Directions: If the statement is true, write true. If the statement is false, change the sentence to make it true.5. The deeper down inside Earth, the greater the pressure.True6. The temperature inside Earth decreases as depth increases.False. The temperature increases with depth.7. The crust is the thinnest under mountains.False. The crust is the thickest under mountains.
7 Directions: Pick the type of rock that is being described. 8. Oceanic crust is typically8. Basalt or Granite9. Grain size is coarse9. Basalt or Granite10. Light in color10. Basalt or Granite11. Grain size is fine11. Basalt or Granite12. Dark in color12. Basalt or Granite13. Continental crust is typically13. Basalt or Granite
8 Directions: Pick if each describes the crust, mantle, the outer core, or the inner core. 14. A dense ball of solid iron and nickel14.15. A layer of hot, solid rock below the crust15.16. Earth’s outer skin of rock16.17. The layer made up of molten iron and nickel17.18. Solid metal, dense ball18.19. Molten metal, liquid layer19.20. Includes both dry land and the ocean floor20.21. The lithosphere, asthenosphere, and mesophere are part of this layer21.
9 Directions: Pick if each describes the lithosphere, asthenosphere, or mesosphere 22. Beneath the asthenosphere, it is is hot, but more rigid22.23. Uppermost part of the mantle that includes the crust23.24. Can bend like a metal spoon, the lithosphere floats on top of it24.
