Crust, core, mantle
Name the layers of the Earth in order from
thinnest to thickest.
Row 1, Col 1
Conduction, convection, radiation
Name the 3 types of heat
transfer and give an example
of each type.
1,2
Compare the density and
composition of oceanic
and continental crust.
DD
1,3
Harry Hess, sonar
What scientist helped to discover
the process of sea-floor
spreading? What type
of technology was available
to him that helped him
prove his theory?
1,4
molcules in the substance move apart and make it less
dense
How does the density of most
liquids and/or gases
substances change when heated?
Why?
2,2
What did the scientist see that supported
sea-floor spreading while in the Alvin
submersible?
More oceanic crust is subducting than is being created
The Pacific ocean is shrinking!
Explain how this
could be happening
2,3
Juan de Fuca, Pacific, Eurasian, African
Name 3 plates that interact
with the North American plate
2,4
Very uppermost part of the mantle and crust
What layer(s) of the Earth
makeup the lithosphere?
Explain
3,1
Heat=less dense=rises=cools=increase density=cycle
Describe how convection currents
form in a lava lamp?
3,2
Matching coastlines, fossils/climate, land feature
Name and explain 3 pieces of
evidence
that supported Wegener’s
hypothesis
3,3
Divergent (C-C)
What type of boundary
formed Iceland?
Name the 2 plates
3,4
What is an island arc?
Name 3 island arcs
formed by the Ring
of Fire.
4,1
Heat from stove, heat from fire
Besides from the Sun,
name 2 other examples of
radiation
4,2
S. America, Africa
Name two continents
that lie on the equator
4,3
San Andreas Fault(T) / Cascades (C) /Mid-Atlantic
Ridge(D)
Name one actual place here on
the N. American plate, formed
by each type of plate
boundary
DD
4,4
Seismic waves, age of rock on ocean floor
How do we know what
the interior of the Earth is like?
5,1
Upper mantle and outer core
Name two layers of the Earth that
have convection currents.
5,2
Could not explain what force pushed and/or pulled the
continents
Why was Wegener’s hypothesis
rejected?
5,3
Mountains, valleys, trenches, islands, volcanoes
Name one feature that occurs
at each of the 3 plate boundaries
