Transcript of Continental Drift
Drift Climate evidence Same fossil at a difference continent
Big Continents Fit in together perfectly North America, South America,Antarctica, Australia India, Africa, Europe, and Asia Coast lines fit in like a puzzle Glacial areas define an ancient pangea Antarctica and Australia Freeze dead plant Antarctica was warmed enough Glossopteris plant tongue-shaped leave South America, Africa, India, Australia, Antarctica Mesosaurus a marine reptiles Founded South America, and South Africa Pangea 1915, Gelogist/meteorologist proposed a theory
Alfred Wegener made a hypothesis What is the discovery? Form a gigant landmasses Millions years ago Pangae spread apart Named Pangaea meaning "all earth" Hypothesis The continents used to formed together Credited Theory Was Denied? Proposed in 1915, accept in 1960 1960 _ 1915 ? 45 Years No mechism involve the continents move
Didn't have enough detail of explaination Continent broke through ocean crust Professional in meterologist not geologist Evidence Climate evidence Same fossil at a difference continents
Big Continents Fit in together perfectly North America, South America,Antarctica, Australia India, Africa, Europe, and Asia Coast lines fit in like puzzle Glacier areas define an ancient pangea Antarctica and Australia Frozen dead plant Antarctica was warmed enough Glossopteris plant tongue-shaped leave South America, Africa, India, Australia, Antarctica Mesosaurus a marine reptiles Founded South America, and South Africa Hypothesis Continents used to formed giant landmasses Continental Drift Theory Alfred Wegener proposal was DENIED Explanation wasn't clear about landmasses move He knew he was right Couldn't prove his idea Theory was too incredible to believe Beneficial Drawing attention to many earth Science Encourage geologist, meteorologist, oceanographer to explores Discuss about the changes Present The idea expand to plate techonic Better understanding on sea floor spreading Detail involved with earth crust "the plates are made up of continental and oceanic crust, which both drift over Earth's surface" Speed about 2.5cm-3cm per year MOST CREDIT Alfred Wegener Abraham Ortelius Alexander Du Toit Arthur Holmes Edward Suess Many other scientists who contributed " What kind of forces could be strong enough to move such large masses of solid rock over such great distances?"
