The layer of the Earth made up of the rocks basalt and
granite
List the layers of the earth starting at the surface and
moving towards the center
Describe Earth’s mantle
Describe Earth’s inner core
Where do convection currents flow in Earth’s layers?
What does Earth’s spinning inner core create?
What happens to temperature and pressure as depth
beneath Earth’s surface increases
How is heat transferred beneath Earth’s surface
What will happen to convection currents beneath Earth’s
surface as the core cools?
Describe what Wegner’s Continental Drift theory says
about the plate motion.
The term used to describe where ocean floor sinks into a
deep ocean trench.
What is Pangaea?
Where does molten material rise from the mantle?
What do we call ancient organisms that are preserved in
rock?
What is a mid-ocean ridge?
List three types of evidence that Wegener used to support
his theory.
17 Why was Wegener’s theory rejected by most people?
18 What is the source of the energy which causes Earth’s
plates to move?
19 At what type of boundary does a rift valley form?
20 What is the theory that states that Earth’s plates are in
constant motion?
21 What is the name of the boundary where two plates
collide?
22 What landforms are made where two continental plates
converge?
23 What is the name of the boundary type where two plates
slide past each other?
24 What landform is made where two continental plates
diverge?
25 How did Wegener decide on the name for the land mass
when all continents were once joined together?
26 What is the name of the theory that states all continents
where once joined together but have since drifted to their
present positions?
27 What do we call the sections of the lithosphere that float
on top of the asthenosphere?
