10 Questions
According to Frank B. Taylor, what caused the movement of continents?
Tides
What was the flaw in Alfred Wegener's 'Continental Drift' theory?
Unexplained reason for continents being connected now
According to Arthur Holmes, what is the main driving force behind the movement of tectonic plates?
Convection currents
What technological advancement resulting from World War II was later used to determine water depths?
Sonar
Harold Hess is credited with the discovery of which oceanic feature?
Guyots or Seamounts
What did the discovery of seafloor spreading by Harold Hess and Robert S. Dietz demonstrate?
Magma erupts onto the seafloor, pushing two plates in opposite directions to create new oceanic crust
What did Tuzo Wilson propose in relation to hotspots in the mantle?
Tectonic plates move over fixed hotspots, creating volcanoes that ultimately erode and form guyots
How do hotspot tracks contribute to understanding tectonic plate movements?
They record the direction and velocity of moving tectonic plates through the formation of guyots
What is the significance of the magnetic polarity stripes found in basalts at mid oceanic ridges?
They confirm the theory of seafloor spreading by showing the direction of moving tectonic plates
What is the role of transform margins according to Tuzo Wilson's description?
Transform margins connect subduction zones and mid ocean offset ridges in a third type of plate boundary
Test your knowledge on the theories proposed by Frank B. Taylor and Alfred Wegener regarding the movement of continents and the formation of mountains. Learn about the rejected hypothesis of mountain formation due to continent movement and the concept of Continental Drift suggesting a supercontinent named Pangea.
