Most tectonic plates have both oceanic and continental crust. How are they different?
Oceanic is thinner and less dense than continental.
Continental is thinner than more dense than oceanic.
Continental is thicker and less dense than oceanic.
Oceanic is thicker and more dense than continental.
Wegner used the following as pieces of evidence...
fit/shape of continents

all of the above
What is the force that moves the continents?

As you travel from the crust to the core, how would temperature, pressure and density of the material change?
They would all increase
They would all decrease.
Nothing, the layers are made of the same material throughout
Temperature would decrease, but pressure and density would increase

ferns
pine trees
shark
squirrel
In which kind of rock do we usually find a fossil?

Samples from inside Wells
According to the theory of continental drift, why do the coastlines of Africa and South America appear to fit together so well?
Africa and South America used to be joined together, but split apart long ago.
Africa and South America are drifting towards each other and will soon fit together perfectly.
Ocean currents on either side of the Atlantic have eroded the coastlines into the same shape.
The theory does not explain why the coastlines seem to match.
What evidence supports the idea that all the continents were once joined together?
Similar rocks found on different continents.
Mountains created by colliding continents.
Evidence of glaciers in unexpected places.
All of the above.
Lystrosaurus was a slow-moving, plant-eating reptile that lived over 250 million years ago. Fossils of Lystrosaurus have been found in the brown areas shown below. How is this explained by the existence of Pangaea?
Lystrosaurus swam across the oceans from one continent to another.
Lystrosaurus drifted on rafts of vegetation from one continent to another.
Land bridges once crossed oceans to connect Africa, Antarctica, and India.
Africa, Antarctica, and India used to be joined together into a single landmass.
Wegener found fossils of land reptiles on two different continents. This was important because
Land reptiles are often found all over the world, showing that they can survive in most climates
Land reptiles cannot swim, so the continents must have been connected for them to get across
Land reptiles are never moved around the Earth by humans, so they must have travels to these continents by themselves
Land reptiles fossilized much better than other animal species
Wegener found fossils of ancient ferns on Antarctica, this shows
That some ferns can survive temperatures well below freezing
That humans put ferns on Antarctica millions of years ago
That Antarctica drifted from a warmer climate where plants could grow
That fossils can be formed in cold climates
Why was Wegener's hypothesis not accepted?
He could not explain what force was moving the continents
He was a meteorologists, so no one took him seriously
He did not have enough types of fossils to support his theory
Because scientists thought Harry Hess' theory was better
Wave that can travel through solids only.
P Waves
S Waves
What layer of the earth are you entering at C on the graph?
crust
mantle
outer core
inner core
How are the two types of waves different from each other?
Within the earth, P waves can travel through solids and liquids, whereas S waves can only travel through solids.
Within the earth, S waves can travel through solids and liquids, whereas P waves can only travel through solids.
Why did the S-Wave stop moving at a depth of 2900 km?
Because the medium changed from solid to liquid
Because P-waves cannot travel through liquids
The seismograph station cant read S waves
S waves move faster than a seismograph can detect
