Alfred Wegener
Alfred Wegener's theory
WHAT IS... Continental drift
When two plates move towards eachother
WHAT IS... Convergent
Mountains
WHAT IS... Convergent
Divergent Spreading
gap in the lithosphere causing magma
to push up on the plate, pull it apart.
LT3SC1- I can use a model to explain where tension and sudden motion are most likely to occur.
Best answer- EQ model video, others are good too!
What two plates fit together like puzzle pieces
WHAT IS... Africa and South America
When two plates move away from each other
WHAT IS... Divergent
Volcanos
WHAT IS... Divergent
Transform slip
Two plates next to each other are rubbed up
against one another and they slide past, can
cause an earthquake.
LT3SC2- I can use a model to explain why plate bounderies are where molten matireal is most likely to break through at the lithophere
Best answer- EQ model video, others are great too!
The weakness of his theory
WHAT IS... He couldn't explain how the plates moved
When two plates move past each other
WHAT IS... Transform
Earthquakes
WHAT IS...
Almost all interactions,
CC-CC, OC-OC, OC-CC
Convergent Subduction
heavier oceanic plate is pushed down below a
lighter continental plate, causing it to melt and
create volcanoes further inland.
LT4SC1- I can explain that plate motion is too small to be detected easily but any type of motion can cause earthquake waves to be relesed along plate bounderies
Best answer- Review games would have helped the most on this one!
Alfred Wegener's job
WHAT IS... Meteroligist
When a plate slides under another
WHAT IS... Subduction
What created the Himalayas
WHAT IS... As CC converges, the crust is being folded and uplifted.
Convergent Collision
when two continental plates of the same densities
come together like a slow motion car crash. The
land buckles and pushes up to create mountains.
LT4SC2- I can use a model to show the longer the tension builds the more energy will be relesed as an earthquake
Best answer- EQ model video
The 5 pieces of evidence Alfred had.
WHAT IS...
1. Continents fit together
2. Fossils
3. Glaciers
4. Coal deposits
5. Mountains and rocks
Where does old oceanic crust go
WHAT IS... into trench
What can create powerful earthquakes but no volcanos
WHAT IS... Transform
BONUS WORTH DOUBLE POINTS
What precent of volcanos are in the ring of fire
3/4 or 75%
Did you hit it? Give me 3 examples of things we did.
-Alfred Wegener's rap songs
-Din slides
-EQ model video
-Review games, ect...
