physical properties
f)
g)
h)
i)
j)

outer core
inner core
k) magnetic field
l) magnetic poles
m) compass
2. By what two things do we break Earth up into
layers (what are the two “lenses” we use)?
3. List the layers of Earth based on composition.
4. List the layers of Earth based on physical properties.
5. Which layer of Earth based on composition is thicker and
denser than the crust & is found between the crust and core?
6. Which layer of Earth based on composition is the
outermost, thinnest layer?
7. Which layer of Earth based on composition is found below
the mantle, is composed of iron and nickel, and is the place
where convection takes place?
8. What are the two types of crust?
9. Which type of crust is denser?
10. Which layer of Earth based on physical properties is
made of solid, slowly flowing rock on which tectonic
plates move and is found below the lithosphere?
11. Which layer of Earth based on physical properties is the
solid, dense center of the Earth and surrounded by the outer
core?
12. Which layer of Earth based on physical properties is
the outermost layer made of the crust and rigid upper
mantle and broken into tectonic plates?
13. Which layer of Earth based on physical properties is the
liquid layer of Earth where convection takes place?
14. In what ways are manufactured magnets and Earth similar?
15. What creates Earth’s magnetic field?
16. What is a compass used for?
17. How does a compass use magnetism?
18. Label the sides of the diagrams below as “composition” or “physical properties.” Then label each layer clearly, spelling the
layer correctly.
SHORT ANSWER QUESTIONS: This test will not include a constructed response, but it will include two short answer questions.
The questions as they will appear on the test are below.
19. How does a compass use magnetism to aid in navigation?
20. Describe the different ways in which Earth is broken up into layers (the different lenses used to look at it). Be sure to include a
description of composition and physical properties in your answer.
