Chapter 1 Section 2: Earth’s Interior
1. What are the 2 main types of evidence that geologists use to learn about Earth’s Interior? Direct Evidence from Rock Samples Indirect evidence from seismic waves
2. What is pressure? Pressure results from a force pressing on an area.
3. What causes the Earth’s magnetic field? Scientists think that the movements in the liquid outer core create Earth’s magnetic field.
4. Directions: Label the layers of Earth by writing the name of the layer in the blank.
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. True 6. 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.
Directions: Pick the type of rock that is being described. 8. Oceanic crust is typically8. Basalt or Granite 9. Grain size is coarse9. Basalt or Granite 10. Light in color10. Basalt or Granite 11. Grain size is fine11. Basalt or Granite 12. Dark in color12. Basalt or Granite 13. Continental crust is typically13. Basalt or Granite
Directions: Pick if each describes the crust, mantle, the outer core, or the inner core. 14. A dense ball of solid iron and nickel A layer of hot, solid rock below the crust Earth’s outer skin of rock The layer made up of molten iron and nickel Solid metal, dense ball Molten metal, liquid layer Includes both dry land and the ocean floor The lithosphere, asthenosphere, and mesophere are part of this layer 21.
Directions: Pick if each describes the lithosphere, asthenosphere, or mesosphere 22. Beneath the asthenosphere, it is is hot, but more rigid Uppermost part of the mantle that includes the crust Can bend like a metal spoon, the lithosphere floats on top of it 24.
