-Named and formulated the “super-continent” Pangea

-Found evidence in land formation, fossils and climate]]> 2023-10-24 12:21:04 UTC https://padlet.com/addison_lee1/avgdr8m0mvi35suo/wish/2760918202 addison_lee1 https://padlet.com/addison_lee1/avgdr8m0mvi35suo/wish/2760918859 ⭐️ Theorized that convection currents in the mantle are the mechanism behind continental drift 

-Researched the ocean to prove the theory of sea floor spreading 

-Was the first of his time to estimated the earth was 4 billion years old and was close to the time frame of its eras]]> 2023-10-24 12:21:33 UTC https://padlet.com/addison_lee1/avgdr8m0mvi35suo/wish/2760918859 addison_lee1 https://padlet.com/addison_lee1/avgdr8m0mvi35suo/wish/2760919804 ⭐️ Magnetometer data was used to map the ocean floor and reveal it’s hidden features

-The magnetometer was originally used to detect enemy submarines in ww2

-The data showed rifts, mountain ranges and trenches underwater as well as the seafloor’s magnetic properties (aka magnetic striping)]]> 2023-10-24 12:21:58 UTC https://padlet.com/addison_lee1/avgdr8m0mvi35suo/wish/2760919804 addison_lee1 https://padlet.com/addison_lee1/avgdr8m0mvi35suo/wish/2760920035 ⭐️ Published the idea of seafloor spreading 

-Observed all the evidence from the echo sounders as a naval officer in ww2

-Discovered and named guyots (flat-topped underwater mountains)]]> 2023-10-24 12:22:09 UTC https://padlet.com/addison_lee1/avgdr8m0mvi35suo/wish/2760920035 addison_lee1 https://padlet.com/addison_lee1/avgdr8m0mvi35suo/wish/2762807691 The theory of plate tectonics explains earthquakes, volcanoes and mountain ranges.]]> 2023-10-25 12:29:22 UTC https://padlet.com/addison_lee1/avgdr8m0mvi35suo/wish/2762807691
