By measuring
seismic waves from
earthquakes.

Starting at the surface,
what are the layers of
the Earth, in order?

Crust
Mantle
Outer Core
Inner Core
Ocean crust is made of
_______, while the
Continental crust is made
of _______. Which is
more dense?
Basalt & Granite.
Basalt / Ocean crust
is more dense.
Back to
Menu
Describe the Mantle.
Talk about its thickness
and state of matter.
The Mantle is the layer of
molten material beneath the
crust. It has a plastic-like state of
matter and is the thickest of
Earth’s layers.

What causes Earth’s
magnetic field, and why
is this field important?
The spinning and churning of
Earth’s liquid iron outer core.
The magnetic field protects us
from the Sun’s solar winds.

Define heat.
The energy transferred
from a hotter object to a
colder one.

Menu
True or False: there are 4
types of heat transfer.
Name them!
False. There are 3 types of
heat transfer: Conduction,
Radiation, & Convection.
Back to
Menu
Define Radiation heat
transfer. Give two examples.
Radiation is heat transfer
through space (do not touch
directly). Examples: the Sun
& camp fire.

If the formula for Density is Mass
divided by Volume, how can heat
change an object’s density?
Heat = Energy. Giving an object
Energy lets the particles move
faster & further away from each
other, increasing Volume and
decreasing Density.

Describe the entire
process pictured below.
1. Pot is heated by stove - Conduction
2. Water is heated by pot - Conduction
3. Heated water spreads out (energy),
+Volume & -Density so it rises.
4. Spreads out at top of pot, bumps into
other particles, -Energy.
5. Less energy means -Volume,
+Density, water sinks.

How many pieces of evidence for
Continental Drift does the photo
below contain? What are they?
Three pieces of evidence. A) The
continents fit like puzzle pieces. B)
Mesosaurus fossils were found on both
continents. C) Africa & S. America have
the same folded mountains.
Back to

What is Wegener’s
Theory of Continental
Drift and why was it
rejected?
The continents were once a
supercontinent called Pangea,
and are slowly moving, even
now. Wegener had no evidence
to explain what caused the
continents to move.

While researching in Antarctica,
you discover the fossil remains
of the tropical plant of
Glossopteris. This plant is native
to Australia. What does this tell
you about Antarctica?
•Antarctica and Australia were at one
time connected (since the plant can not
migrate).
•Antarctica once had a tropical climate.

What do the reversing magnetic
stripes on the ocean floor reveal?
Use this information to explain the
difference between “magnetic”
North and “geographic” North.
Stripes tell us that magnetic poles
reverse every 300,000 years.
Geographic North is always at 90⁰
North. Magnetic North is where the
magnetic field originates.

Why is the theory of SeaFloor Spreading important?
It provides the final piece of
evidence – the mechanism –
for Continental Drift.

Describe the Mid-Ocean
Ridge and why it’s important.
Underwater mountain range
where magma cools to form
new crust. Stretches across all
the oceans of the world.
Back to
Menu
Where is old crust destroyed and
what is it called when the crust sinks
back underneath, into the mantle?
The crust is destroyed at deepsea Trenches in a process
known as Subduction.
Back to
Menu
Studying the crust at the MidOcean ridge reveals 3 pieces
of evidence for Sea-floor
Spreading. What are they?
1. Formation of “pillow” basalts
2. Reversing magnetic stripes
3. Relative age dating of core
samples
Back to
Menu
Describe the process of Seafloor Spreading and why it
is like a conveyor belt.
1. Magma rises at the Mid-Ocean Ridge
2. Entering the ocean, magma cools into Basalt
3. New magma rises and cools, spreading the
rock out
4. Old crust subducts under less dense crust
and melts
5. The cycle repeats!

Plate Tectonics combines the
theories of Alfred Wegener & Harry
Hess with a method of heat transfer.
Name the theories and method.
Continental Drift & SeaFloor Spreading and the
heat transfer method of
Convection.

Plate Tectonics states that plates
in Earth’s lithosphere move by
floating on the mantle. What are
the 2 types of plates?
Plates can be classified as either
Continental or Oceanic crust.

by the following motions.
Convergent, Divergent, and
Transform boundaries.
