Continental

According to Wegener's hypothesis of continental drift,

• Earth's surface is made up of seven major landmasses

• the continents DO NOT move

• Earth is slowly cooling and shrinking

• the continents were once joined together in a single landmass, and these plates will continue to move.

The Appalachian Mountains in the U.S. match up with a similar mountain ranges in northern Europe. How does this support Wegener's theory of Continental Drift?

• The mountains were formed after tectonic plates had moved away from each other

• The similarities provide evidence North America & Europe were connected when the mountains formed.

• Similar rock samples were found on the ocean floor and at the two mountain ranges indicating that they both formed around the same time.

• This evidence does not support the theory of continental drift.

Why did no one believe Wegener's ideas about continental drift? (Choose 2)

• He could not successfully explain HOW the continents moved

• He didn't have evidence that supported his ideas that the continents had once been connected

• They were biased against his ideas because he was German and a meteorologist

• He didn't use the right technology to gather data

What is this a picture of?

• plate tectonics

• continental drift

• pangea

• glacier scaring

Alfred Wegener used all of the following for evidence of his idea EXCEPT...

• The shapes of the continents fitting together like a puzzle

• Similar fossils on different continents

• Comparable modern weather patterns on different continents

• Similar rock formations on different continents

Which of the following best describes Wegener's continental drift ideas?

• Hypothesis: There was data to support the idea but more information was needed to build it into a scientific theory.

• Theory: It was an early idea of Wegener's but it didn't yet have any evidence to support it.

• Theory: It was a well supported idea that explained many things. No additional information was needed (it just needed time for people to accept it).

• Hypothesis: It was an educated guess that Wegener made based on maps, but he hadn't yet collected experimental data.

What do we call the idea that the continents were once together and then slowly moved across the Earth's surface?

• Plate fusion

• Continental drift

• Convection currents

• Continental plates

What was Wegener's hypothesis?

• All continents were united in a single landmass and have since separated.

• All continents were situated as they have been for billions of years.

• All continents are united in a single landmass as they have been for billions of years.

• All continents were very separate and have since joined into a single landmass.

Give an example of evidence provided by terrestrial features

• Freshwater fossils were found in places separated by oceans, they could not have swum so far

• Tropical fossil remains found under Arctic ice where it used to be a warmer area

• Mountain ranges on two different continents separated by the ocean that align, same age and same type of rock

• Glacial striations found in South Africa

Why was Wegener's theory rejected?

• Because Wegener was really a legitimate crazy little man

• Because he did not have enough support from his scientific colleagues

• Because he could not identify the force or cause behind the movement of the continents

• Because he found evidence of matching fossils, matching land features, and evidence of climate change to support his idea
