Continental Drift By: Vanessa, Nina, and Sarah. 1.Continental Drift was a hypothesis that that the continents broke apart and moved slowly to their current.
What is it? Continental Drift - Earth’s continents were once joined in a single landmass, and gradually moved, or drifted apart. People thought this for.

Continental Drift Activity 41

Activity 41: Continental Drift Challenge: What is the evidence that the continents have moved? Key Vocabulary: Continental Drift  The idea that the continents were once a giant landmass that broke into pieces and slowly drifted away from each other. READ the Introduction on page D-27!

Glue in SS 41.1 “Analyzing Evidence: Continental Drift” You have a three-part task: Determine which statements constitute evidence; Identifying the pieces of evidence that support and contradict the idea that continents have moved; and Explaining how each piece of evidence supports or contradicts this idea. Follow your procedure on page D-28!! When you are finished, Answer Analysis Questions 1 and 2 in your notebook.

Analysis #1 X Same kind of plant was found in different parts of the world. Since plants can’t move, one explanation is that these different part of the world were once connected

X It helps explain why places with warm climates today could have had cold climates in the past. It also proposes the formation of a single large ice sheet at that time rather than several different ice sheets.

X It shows a pattern of geological features in line with the suggested single land mass

X It is highly unlikely that rock layers in two different parts of the world, affected by different forces, formed exactly the same sequence of layers and fossils if they had not been joined.

X It shows how precisely two of the continents could have once been attached. (If they were not attached, how could they fit so well?)

X It shows that the continents are now moving. This means that they could have moved in the past. Over billions of years, a few centimeters per year could result in a distance of thousands of kilometers.

X It shows the same worm fossil in different parts of the world. One explanation for finding the same worm fossil in places that are so far apart and have such different climates today is that these areas were connected and had the same climate.

Analysis #2 Three other people are described as having contributed evidence in support of continental movement: Eduard Seuss Alexander du Toit Edward Bullard Other scientists are not mentioned on SS 41.1, but we can assume that many scientists have worked on collecting the evidence.

Assignment: You will be answering Analysis Question #3 as a graded question. This is a UC Assessment (Understanding Concepts)
