Worksheet time: 20mins
Which of the following is NOT a piece of evidence presented by Wegener to support Continental Drift
Plant and animal fossils on different continents
Matching landforms on different continents
Magnetic striping on the ocean floor
Puzzle fit of modern continents
What is this a picture of?
plate tectonics
continental drift
pangea
glacier scaring
Originally the Continental drift theory was not well received by other scientists. Why?
There was a competing theory at the time that was more believable.
There was no data showing the continents ever moved.
Wegener could not explain the mechanism that made continents move
The scientist presenting the data was unreliable.
Which of the following scientists discovered sea floor spreading?
Wegener
Hess
Einstein
Churchill
What is an underwater mountain range where new ocean floor is made?
subduction
mid-ocean ridge
deep-sea trench
Plate Tectonics and Continental Drift are the same thing
True
False
What two components make up the Plate Tectonic Theory?
Continental Drift and Magnetic Striping
Continental Drift and Seafloor Spreading
Seafloor Spreading and Plate Tectonics
What evidence helped Harry Hess prove that sea-floor spreading was occuring
Ocean crust gets older as you move away from mid ocean ridges
Underwater mountains
Fossils of plants and animals
Puzzle fit of the continents
What evidence helps scientists show how sea floor spreading occurs?
Age of oceanic crust
Magnetic Stripes
New Crust created at Mid ocean Ridges
All of these
