<Image - On the image place an arrow at
the right coast of South America and one
at the left coast of Africa>
If you have ever looked at a map of the
world, the coastlines of Africa and South
America seem to fit together like pieces of
a jigsaw puzzle.
http://www.pd4pic.com/geography-globemap-world-earth-silhouette-free.html
<Image>
The fit between the 2 coastlines is even
more prominent when their continental
shelves are compared.
The continental shelf is the part of a
continent that is submerged in relatively
shallow waters.

Evidence that these two continents might
have been joined came from the research
of a German geographer who traveled the
world collecting specimens and studying.

Mountain ranges in South America match
ranges in South Africa. They appear to be
the same age and formed of the same
kinds of rock.

Similarities have also been observed
along ranges in Europe and North
America.

Fossils of animals and plants on either
side of the Atlantic Ocean also have
striking similarities.
The idea of continental drift was formed…

Finally, evidence involving hardened lava
showed that the Earth’s magnetic field had
not changed.

Scientists concluded that the continents
had once been part of a single large land
mass known as Pangaea. (Pan-jee-uh)
Over millions of years this landmass has
divided multiple times into the present day
continents.

A. has been the same since the beginning of time.

In the 1930s geologists and other
scientists discovered a ridge in the middle
of the Atlantic seafloor through which hot
lava was flowing upward and spreading
outward.
<Image - Zoom in on the areas along the
ridges (red)>
The lava farthest from either side of the
ridge was the oldest.
In this image, the oldest areas are blue,
and the younger ones are red along the
ridge.

The discovery that the ocean floor was
spreading led to the modern theory of
plate tectonics.
Plate tectonics is the name for the theory
of the Earth’s crust being divided into
plates that glide over the flexible mantle.

Plate tectonics suggests that the Earth’s crust is:
A. composed of a number of large plates.

Mountain ranges are constantly subjected
to erosional forces, which work to tear
them down.
The rugged topography of a mountain
range is the product of erosion.
<Image-Zoom into the green area,

the sedimentary rock>
The basins adjacent to an eroding
mountain range are filled with sediment,

Earth’s continents are changing, moving,
and rearranging themselves over a span
of millions of years—this affects the
Earth’s climate and organisms as well.

Let’s review how this happens….
Our planet Earth has four interior levels:
the crust, mantle, outer core, and inner
core.
<Image - Display image, then after audio
is read, Place circles around the terms
Lithosphere and Athenosphere>
The crust and part of the mantle form the
lithosphere. This portion of the Earth is
rigid, solid rock.
Directly beneath is the mantle, which is
hot enough that it is flexible. This is the
asthenosphere.

There are several forces pushing and
pulling the plates in different directions.
This interaction keeps the landmasses
moving…very slowly.
QUESTION E
The asthenosphere can be described as:
A. rigid and rocky
B. hot and fluid-like
C. solid metallic
D. hot and solidified

Throughout the Earth’s 4.5 billion year
history, tectonic plates’ collisions and
upheavals have formed mountain ranges
and carved out basins.

Some volcanoes, like those in the
Hawaiian Islands, form from a hot spot,
which is a weakness in the Earth’s crust
where magma forces its way to the
surface.

With the flow and eventual cooling of the
magma and lava, the Earth’s surface is
forever changing, as seen in this lava field.
