Write the questions then find the
answers either in your notebook or
the textbook. You may work
together as long as you don’t make
toooooo much noise.
• What do you need to find the density of a rock?
Graduated cylinder and triple beam balance
• Tectonic plates consist of continental & oceanic
crust
• What do we use to find out and map what the
interior of the earth is made of and would look
like? Seismic waves
• Sea-floor spreading occurs at divergent
boundaries
• Wegener’s large continent was called Pangaea
• What was the ocean called? Panthallassa
• Evidence for sea-floor spreading comes from
magnetic reversal
• The inner most layer of the earth is the inner
core
• What is it called where 2 plates meet?
boundaries
• How do mid-ocean ridges support both the idea
of continental drift and the theory of plate
tectonics? Fossil and plant evidence
• How does fossil evidence support Wegener’s
hypothesis of continental drift? Fossil and plant
evidence far away from each other on different
continents
• Sea-floor spreading occurs at which type of
boundary? divergent
• What does not provide evidence for
continental drift? Oceanic plate theory
• What do scientist use the global positioning
system for? To measure plate movement
• When an ocean plate collides with a
continental plate what happens? Oceanic
plate subducts
• When mining diamonds deep in the earth’s crust,
what do you think will happen to the
temperature? Goes up due to close proximity to
the asthenosphere
• What are the layers of the earth? In order Use 6th
grade words. LAMOI
• Plates move on the asthenosphere
• Name the types of boundaries. Convergent,
divergent, transform
• Volcanoes will probably happen at plate
boundaries
• Most earthquakes happen at plate boundaries
• What are the 2 types of crust? Oceanic and
continental
• Which type of crust is more dense? Oceanic
• What is subduction? One crust goes under
the other (oceanic under continental)
• What part of the earth is molten? Outer core
• What part of the earth is most dense? Inner
core

plate boundaries?

C. Divergent boundaries.
D. Strike-slip boundaries.
At which location would earthquakes be least likely to
occur?
A. 1
B. 2
C. 3
D. 4
Scientists think that present-day continents
were once all joined in a single super-continent
that is represented by the diagram belowThe
name given to this single super-continent is:
Which boundary is which?
A
B
C
