Alfred Wegner
Alfred Wegener was a _________ (a person who studies climate) as well as a __________( a person who studies Earth's structure, formation and processes).
What is a climatologist and geologist
The two continents that Wegner thought fit together like a puzzle.
What are Africa and South America.
What does this theory state?
What is that fossils of plants and animals were found in different parts of the world, but they seem to match up when continents are all aligned.
What does this piece of evidence state?
That mountain ranges were broken apart into different countries due to the continents drifting apart.
What does this theory state?
Present day continents were in different locations in the past and supported a different climate.
Alfred Wegener came up with the theory of continental drift. How many main pieces of evidence did he come up with to support his claim?
What is 4
True or false: Wegner was the first person to notice that the two countries look like they fit together.
False
This was the reptile remains found in South America and Africa that sparked Wegner's interest in this piece of evidence.
What is the Mesasaurous .
Other than matching rock formations in South American and Africa, which other two continents did Wegener find evidence of matching rock formations?
North America and Europe
What is the name of cold moving rock-like structures that naturally drift over time.
What are glaciers
The name of the super continent that existed 250 million years ago.
What is Pangaea
The name of this piece of evidence is called this because of what?
What is the appearance of the coastlines.
What was the name of the continent where Wegner found fossils that would not be able to survive on that land today?
What is Antarctica.
What types of rock are these mountains made of?
What are sedimentary
What do glaciers leave behind that helps scientists gather evidence?
What are glacial striations / glacial grooves
What was Wegner's theory?
What is: The continents were once connected and then somehow were ripped apart.
When comparing the coastlines, it appears that the ________ part of Africa fits with the ________ part of South America. (Your answer must be in order).
What is the west and east.
What was the name of the rock Wegner found in colder climates, indicating at one point these countries were tropical?
(Bituminous) Coal
Wegner thought the mountain ranges in South America and Africa were the same was because of what?
They were made of the same rock and they were the same age. They both had traces of volcanic rock from the same eruption.
What do glacial striations tell us?
They leave behind scratches that help that bring old rocks with them to different parts of the world and then they are able to see where these rocks once were.
Why wasn't Alfred Wegener's theory accepted?
He could not explain how or what caused the continents to move.
What named continent today did Australia seem to be apart of when Pangea existed?
What is Antarctica.
The name of the plant fossil found in most present day continents.
Glossopteris
A scientist finds fossils of several different species of fish on top of a mountain. What do these findings most strongly suggest about the region?
Where did Wegener find a coal bed that could not have been created in the present due to its climate?
Antarctica
