EARTH LAYERS REVIEW
1. Name the compositional layers of Earth in order, starting on the surface and moving to the center.
CRUST, MANTLE, OUTER CORE, INNER CORE
2. Earth’s core (both inner and outer) is made of NICKEL AND IRON.
3. The hottest layer of Earth is the __INNER CORE_. The layer with the highest pressures is the _____
INNER CORE ____. The layer with the highest density is the _ INNER CORE _.
4. Name the physical layers of Earth in order, starting on the surface and moving to the center.
LITHOSPHERE, ASTHENOSPHERE, MESOSPHERE, OUTER CORE, INNER CORE
5. What are the two types of crust? CONTINENTAL AND OCEANIC
6. What physical layer of Earth is partially molten? ASTHENOSPHERE
7. What compositional layer of Earth is partially molten? MANTLE
8. DENSITY is calculated by taking mass divided by volume.
9. The lithosphere is broken up into pieces called TECTONIC PLATES
10. Continental crust is made up of the rock GRANITE (EXAMPLE: STONE MOUNTAIN)
11. Oceanic crust is made up of the rock BASALT (REMINDER: OCEAN WATER AS SALT… SO IT’S BASALT)
12. The pieces of the lithosphere float on which physical layer of Earth? ASTHENOSPHERE
13. What layer of Earth is made of totally molten iron and nickel? OUTER CORE
14. Which compositional layer of Earth is made of totally solid material? INNER CORE BECAUSE IT HAS SO MUCH
PRESSURE FROM THE OUTER LAYERS. It is pressed into solid.
15. Which is thicker? Continental crust or oceanic crust? CONTINENTAL CRUST
16. What kind of crust is found underneath the continents? CONTINENTAL CRUST
17. The lower part of the mantle is called the MESOSPHERE.
18. Is the molten iron and nickel in the outer core spinning? (yes or no) YES. THIS CREATES THE EARTH’S MAGNETIC
FIELD.
19. Is granite found underneath the continents or underneath the oceans? CONTINENTS
20. Write down a question you have OR write about something you don’t understand (applies only to Earth’s
layers).
