Screen+Shot+Postings

Read and take notes from your textbook pages 37-42. Find a source, other than our book, that contains information on one of the following topics. Choose an on line encyclopedia, or some other source that contains both an image and text in association with the topic of your choice. Pick a topic that no other student picked in the class. Take a screen shot (press the Prnt Scrn button on your computer) and paste the image into a blank word document and write a summary of what is seen in the image and what is said in the text. **Danger – Plagiarism!** Make sure your summary is not too similar to the text and make sure you give credit to the author of the material you took a screen shot of. See example after the list of topics: 1.Alfred Wegener, 2.Continental Drift, 3.Pangaea, 4.jigsaw fit of continents from opposite sides of the Atlantic Ocean, 5.fit of continental coastlines vs. fit of continental shelves, 6.What causes the gaps and overlaps when the edges of complimentary continents are rejoined, 7.Mesosaurus evidence to support movement of continents, 8.Glossopteris evidence to support movement of continents, 9.marsupial evidence to support movement of continents, 10.lack of growth ring evidence in fossil fern trees to support movement of continents, 11.coal field evidence to support movement of continents, 12.matching mountain ranges evidence from different continents to support movement of continents, 13.matching similar rock evidence from different continents to support movement of continents, 14.glacial evidence from different continents to support movement of continents, 15.R.T.

Eoanna Giannakopoulos- 8. .Glossopteris evidence to support movement of continents according to Glossopteris the continents at one point had to be togher in order for the plants to spread. Also the picture to the right shows that if the continets were not connected there would be no way of having the plant spread due to the gap between them.

Posting by Sumi Cha 2. __Continental Drift__

Continental Drift is the idea that todays continents used to be a single landmass called Pangaea. The idea of Continental Drift was formed by a German scientist named Alfred Wegener. Continental Drift is caused by the convention current in the mantle. The magma heats up and rises, then it spreads out causing the plates to move, and finally the magma sinks causing the plates to get dragged towards each other. This process is called the subduction.

 * 19. Atlantic Ocean Formation**

The Atlantic Ocean was formed around 150 million years ago around the Jurassic Period. It happened when a rift opened up in the supercontinent of Gondalawanland. The Atlantic Ocean has an average depth of 3926m, or 12, 881 feet.

Convection currents connect to plate tectonics because the currents effect the plates to move in different directions. Image and information: http://www.moorlandschool.co.uk/earth/tectonic.htm

Laksmi Gil- 17. What it is showing is how the molten magma rises to the crust and while it moves towards the sides it brings the plates with it and then proceeds sinking. []

Danny Ward 18. Wegner and the Grrenland ice sheet As you can see in the picture it is explaining how the Greeland ice sheet has been melting and breaking down over time. Also it has information about Alfred Wegener and how he originally discovered the Greenland ice sheet.

Ariana has #6 This is an example and explaination of what causes overlaping whatn continets rejoin

Silviu Pavel Alfred Wegener was the man who came up wit the hypothesis that the earths plates were moving around earth. With no major proof his hypothesis was no accepted untill 1950 when there was more proof of this.Info from the free online encyclopedia: W ikipedia

Cassidy Burns 15.

R.T Chamberlain was a American geologist who didn't think that his theory didn't make any sense. Wagener's theory would later be under a lot of criticism from other geologists throughout his entire life time.

22. Why the Continental Drift is wrong** There are many factors regarding the questions of why the continental drift is wrong like, the earth's crust have incised into land mass. The fossils of Mesosaurus were found in South America and Africa. South America has floated so far away from Africa. The Pacific Rim of Asia and North/ South America had also floated to thier present day positions.
