1.5 LANDFORMS PREVIEW
Geography Lesson: What is a Volcano?
• Watch: http://www.youtube.com/watch?v=WgktM2luLok
• Why Are Volcano’s important for life?
• They are a type of landform that has shaped
the planet through out it’s history.
1.5 DISCOVERY
Biosphere combines the major planetary
sphere’s to create and sustain all life
1.5 DISCOVERY
• Landform Formation
• Internal, or Primary forces shape the earth’s
surface by building mountains, hills, plains,
and plateaus.
1.5 DISCOVERY
Internal or Primary Forces
• Plate Tectonics is the theory that the earth’s
crust is broken into plates.
• Most tectonic activity occurs between these
plates, or faults.
• Tectonic activity includes earthquakes and
volcanoes.
• The continents are on the larger plates, with
smaller plates between the larger ones.
• There are three different kinds of plate
movement: Convergent / Divergent /
Transform

1.6 DISCOVERY
CONTINENTAL DRIFT THEORY
• Continental Drift is the theory that the continents have
changed position and location over geologic time.
1.6 DISCOVERY
CONTINENTAL DRIFT THEORY
• BACKGROUND
•
Although the "continental drift" hypothesis was proposed by
a German meteorologist named Alfred Wegener in 1910, he
was not the first to notice that the coasts of Africa and South
America seem to fit together. But Wegener, working mostly
in the Southern Hemisphere, found other geologic evidence
that convinced him that Africa and South America had at one
time been joined together.
•
The purpose of today's lecture is to learn how circumstantial
evidence can be used to support a scientific hypothesis and
why this type of evidence, by itself, is sometimes not enough
to convince the scientific community of a new idea.
1.6 DISCOVERY
CONTINENTAL DRIFT THEORY
• HYPOTHESIS
•
Based on an apparent fit between Africa and South America,
Wegener hypothesized that at one time all continents were
joined together in a "supercontinent" called Pangaea. The
supercontinent eventually broke into the smaller continents,
which then "drifted" towards their present positions.
•
Wegener supported his hypothesis by using circumstantial
evidence, similar to the way that a detective would collect
evidence to solve a crime. There are four lines of evidence:

CONTINENTAL DRIFT THEORY
1. ROCK DISTRIBUTIONS
2. MOUNTAIN RANGES
3. FOSSIL DISTRIBUTIONS
4. EVIDENCE OF GLACIATION
•
In addition to circumstantial evidence, geodetic surveys also
appeared to directly support Wegener's hypothesis.
1.6 DISCOVERY
CONTINENTAL DRIFT THEORY
• RESPONSE
• Most geologists, especially those in North America, rejected
Wegener's hypothesis. One reason for their skepticism was
the difficulty one encountered in attempting to
"fit" continents of the Northern Hemisphere back
together. But their biggest objection was to
the mechanism Wegener proposed for how the continents
had "drifted"!
