Alfred Wegener
Who is the person responsible for .Theory of Continental Drift
|
convergent, divergent, transform
What are the three MAIN boundaries?
|
Continental Crust
Which layer of crust is more dense than the other?
|
Fossil Correlation
. Alfred Wegener cited 4 pieces of evidence for his theory of continental drift, one piece of evidence was that the Mesosaurus was found on the continents of Africa and South America - but they could not have crossed the Atlantic Ocean. What is this piece of evidence called in scientific terms?
|
Fault
A break in a body of rock along which one block of rock slides past another block of rock is called a ___________.
|
Pangaea
The supercontinent that existed about 200 million years ago was called _______.
|
When 2 plates come together
What is a Divergent Boundary?
|
Mantle
The thickest layer of the Earth is the ___________.
|
Apparent fit of the continents
Alfred Wegener cited 4 pieces of evidence for his theory of continental drift, one piece of evidence was that the continents appeared to fit together like pieces of a jigsaw puzzle. What is this piece of evidence called in scientific terms?
|
Mid-ocean ridges
Mountain chains found on the ocean floor are called ___________.
|
Continental Drift
The theory that states that the continents once formed a single landmass, broke up and drifted to their current locations is called ___________.
|
Transform
The San Andreas Fault is an example of what boundary?
|
Crust, Mantle, Outer core, inner core
Which of the following correctly lists the four layers of the Earth from least dense to most dense?
|
Rock and mountain correlation
Alfred Wegener cited 4 pieces of evidence for his theory of continental drift, one piece of evidence was that he found mountains in North America that were similar in age and made of the same material of mountains that were in Europe. What is this piece of evidence called in scientific terms?
|
seismic waves
Some kinds of ___________ __________ cannot travel through liquids, that is how scientists know that the outer core is liquid.
|
German Meteorologist
What was Alfred Wegener?
|
Plate Tectonics
What is the theory that states that Earth’s lithosphere is broken into many pieces, tectonic plates, that move slowly over the asthenosphere?
|
Liquid
Iron and Nickel
What is the state of matter of the outer core? What is it made of
|
Paleoclimate data
Alfred Wegener cited 4 pieces of evidence for his theory of continental drift, one piece of evidence was that coal was found in a place that is now cold and that glacial striations were found in places that are now hot. What is this piece of evidence called in scientific terms?
|
Mantle
Convection currents occur in what layer of the Earth
|
1. Apparent Fit of the Continents
2. Fossil Correlation 3. Rock and Mountain Correlation 4. Paleoclimate Data
What are Wegener's 4 pieces of evidence to explain Continental Drift
|
Convergent boundaries
Mountains and Volcanoes are features of which plate boundary?
|
Mostly Solid
What is the state of matter of the mantle?
|
Mesosaurus
What is the name of the dinosaur whose fossils were found on different continents?
|
Thickest layer of the Earth
What is a characteristic of the mantle?
