Pangaea The super continent

Pangaea, formed 250- 300 million years ago http://upload.wikimedia.org/wikipedia/commons/thumb/c/cb/Pangaea_continents.svg/220px-Pangaea_continents.svg.png

It survived about 100 million years before it began to break apart http://www.rocksinmyheadtoo.com/Pangea.jpg

The idea that the continents moves, the THEORY OF CONTIENTAL DRIFT, and that they were once a super continent was first proposed by Alfred Wegener http://upload.wikimedia.org/wikipedia/commons/8/87/Alfred_Wegener_1910.jpg

As with any science, we needed proof

Alfred found: 1. Matching rock/mountains on different continents http://tasaclips.com/illustrations/Evidence_from_rock.jpg

2. The shape of the continents http://tasaclips.com/illustrations/Fit_of_Continents.jpg

3. Climate change http://cosscience1.pbworks.com/f/1248192662/Module10-004.gif http://mrsciguy.com/EarthScience/earthsciimages/evidence01.jpg
