INPUT STATION Read It! Theory of Continental Drift – Part 1 Take a look at the diagram of Earth’s continents. What do you notice? Do you think some of them, especially South America and Africa, look a bit like a puzzle? Theory of Continental Drift Type/draw here. Fossils Type/draw here. Continue to Part 2 A scientist named Alfred Wegener thought so, too. He was a German meteorologist and geophysicist and the first to propose the Theory of Continental Drift - the idea that all of Earth’s continents were once joined together in one super continent named Pangaea before breaking apart and gradually drifting into their current positions. Besides the puzzle-like shape of the continents, Wegener had other big pieces of evidence to support his theory. One of which is the location of identical fossils on two separate continents. Fossils are remains of something that was once living that is preserved in a rock. It would not make sense for identical fossils to exist on continents separated by a vast expanse of water. Remains of Mesosaurus, a freshwater crocodile-like reptile, is one of the fossils used to support this theory. It lived between 286 and 258 million years ago. Fossils of this reptile have been found only in Southern Africa and Eastern South America. © Kesler Science, LLC

Theory of Continental Drift – Part 2 It would have been impossible for Mesosaurus to swim the distance between these two continents, so this fossil find suggests that South America and Africa were connected during its lifetime. Lystrosaurus, which means “shovel reptile, ” was a land animal that lived about 250 million years ago. This animal is thought to have been a plant eater. It grew to about one meter in length and had with a stocky build like a pig. Fossils of Lystrosaurus were found in Antarctica, India, and South Africa. This is more evidence to support the claim that these land masses were once linked. Glossopteris was a woody shrub or tree. It was named after “tongue” because of the shape of the leaves. Some of these plants reached 30 meters tall! This plant lived about 299 million years ago. Fossils were found in Australia, South Africa, South America, India, and Antarctica. When the continents are reassembled into a single landmass, it is easy to see how these fossil patterns support the Theory of Continental Drift. © Kesler Science, LLC

Take the blank puzzle pieces and try to put them together in 3 minutes. Explore It! Part 1 Use a stopwatch or your cell phone as a timer. Be careful not to resize the shapes when you drag them. 1. Were you able to finish the puzzle in three minutes? Your Answer: 1. Answer here INPUT STATION Go to Part 2 © Kesler Science, LLC

Explore It! Part 2 The puzzle pieces are like Earth’s tectonic plates. Each plate moves independently of each other. Alfred Wegener is credited with the Theory of Continental Drift, which states that all continents were once a large landmass called Pangaea. Earth’s plates have moved slowly away from each other in the millions of years since. Wegener used four pieces of evidence to support his theory. Alfred Wegener is credited with the Theory of Continental Drift He realized that the continents fit together in many places like puzzle pieces. Most notably, South America fits almost perfectly with Africa. He found similar plant and animal fossils in areas where the landmasses would have been together millions of years ago. Alfred Wegener also noticed that landforms like rivers and mountains lined up nearly perfectly when the continents were put together. Lastly, Wegener was able to use climate data to determine there was evidence of glaciers in places on Earth that should have never had ice on it. Go to Part 3 INPUT STATION © Kesler Science, LLC
