fluid:
gas or liquid
Earth's Layers:
seismic waves
What information did scientists study in order to develop this model?
Many scientists believe that crustal plate movement occurs because of
convection cells contained in Earth’s
asthenosphere:
"plastic mantle"
Part of the east coast of South America
and the west coast of Africa have
matching fossils within the same series of
rock layers. This provides evidence that
these two continents were once:
joined together
Studies of earthquake seismic waves have helped scientists determine
the
Earth's Layers
conduction
radiation
convection
currents
Matching
A piece of paper is torn in half.
physical change
Warmed air rises above a lit candle.
convection
A metal spoon gets warm when used to stir hot
soup.
conduction
Sunlight brightens a dark room.

Who first proposed the theory of continental drift?
Wegener
In the convection current of a pot or beaker of boiling water, the cooler,
denser fluid:
sinks
cause: gravity
According to seismic waves from earthquakes, scientists think the
inner core is most likely
a. solid
b. liquid
c. gaseous
d. density
The movement of energy from a warmer object to a cooler object
is called
Heat Transfer
Scientists rejected Wegener’s theory about Pangaea because he could not
describe the push or pull
on the continents
The ocean floor is mostly:
Basalt
As a fluid’s temperature increases, its density
a)increases
b)stays the same
c)decreases
d)none of the above
Scientists who study the forces that make and shape the Earth are called
Geologists

The End!
Study the guide we just put
together; not random
pages in your notebook.
Describe one piece of evidence shown on the map
suggesting that the continents of South America and
Africa were once joined together.
...they look like they fit together
like pieces of a puzzle
