DIFF GEOscience 3rd quarter openers

Feb 23 Mon

Examine the ESRT graph.

  1. Why does continental crust “float” on oceanic crust?
  2. How does density change as you move closer to the center of the Earth?
  3. What is the temperature range of the asthenosphere?  the stiffer mantle?
  4. Why is the asthenosphere considered the “plastic” mantle when it is cooler than the inner “stiffer” mantle?
  5. What evidence do you have that the Earth is composed of different materials?
  6. Earth’s crust varies from 50 -200n Km.  What percent of the Earth’s radius is the crust.  Estimate the radius of the Earth to be 6400 Km.
