The observation that the continents fit together like puzzle pieces, and may once have been connected, led Alfred Wegener to propose a theory in 1910 called1 pointA) continental plowingB) continental driftC) plate tectonicsD: Pangaea

List some of the evidence used by Wegener to support his idea of moving continents.2. What was the primary technical weakness with Wegener’s continental drift theory?3. How were mountains thought to be formed (a) by contractionists and (b) by permanentists?4. How were the trans-Atlantic paleontological matchups explained in the late 19th century?5. In the context of isostasy, what would prevent an area of continental crust from becoming part of anocean?6. How did we learn about the topography of the sea floor in the early part of the 20th century?7. How does the temperature profile of the crust and the mantle indicate that part of the mantle must beconvecting?8. What evidence from paleomagnetic studies provided support for continental drift?9. Which parts of the oceans are the deepest?10. Why is there less sediment in the ocean ridge areas than in other parts of the sea floor?11. How were the oceanic heat-flow data related to mantle convection?12. Describe the spatial and depth distribution of earthquakes at ocean ridges and ocean trenches.13. In the model for ocean basins developed by Harold Hess, what took place at oceanic ridges and whattook place at oceanic trenches?14. What aspect of plate tectonics was not included in the Hess theory?15. The image shows the pattern of sea-floor magnetic anomalies in the area of a spreading ridge. Draw inthe likely location of the ridge.

Although he did not present a mechanism, what were the key points of Alfred Wegener’s proposal for the concept of continental drift?

Wegner's idea of Continental drift was based on __________.2 pointsthe continents and ocean floor are solid because they are hardened magmaconvection in the mantle and gravity slowly move continents around on the Earth’s surfaceocean waves push the continents over the surface of the earththe continents, once joined together to form a large landmass, have moved over time.

While doing his research, Alfred Wegener developed four key pieces of evidence to support the theory of continental drift. In the space below, list each piece of evidence.

The scientific theory of a supercontinent called Pangea was initially proposed by Alfred Wegener in his 1912 work The Origin of Continents. Despite some scientific evidence supporting his claim, other scientists remained unconvinced since his theory lacked a mechanism for how the supercontinent broke apart. ------- Wegener's ideas weren't fully adopted until the 1960s, when the theory of tectonic plates was put forth.Which choice completes the text with the most logical transition? Hence, eliminateMoreover,eliminateNevertheless, eliminateNext,
