Continental Drift Theory and Plate Tectonics Alfred Wegener and the Moving Planet

Alfred Wegener :

Alfred Wegener Born in 1880 Was a German meteorologist and explorer Introduced Continental Drift Theory in his book, The Origin of Continents and Oceans, in 1915 His theory was rejected and ridiculed by his peers

So What is Continental Drift Theory???:

So What is Continental Drift Theory???

How has the Earth changed?:

How has the Earth changed? The Earth as Wegener proposed it looked like about 250 million years ago The Earth as it exists today…

Continental Drift Theory:

Continental Drift Theory The planet used to be one supercontinent called Panagea About 200 million years ago, the continent rifted and the land masses began to move away from each other They moved very slowly, about 1-5 cm/year, about the same speed at which your fingernails grow They are still moving today

Could he Prove It?:

Could he Prove It? He found the proof he needed…now it’s your turn. We are going to take a webquest that will take us back in time to when Wegener first introduced his theory. We will put on our hats as scientists and decide whether we think he was right, and we will find the proof we need to decide!
