Alfred Wegener proposed that tidal forces could cause continental drift as part of his broader theory of continental drift, which suggested that continents were once joined in a supercontinent called Pangaea. He believed that gravitational interactions with the moon and sun could exert enough force to shift continents over geological time. However, this idea lacked sufficient scientific backing and was unable to explain the mechanisms behind the movement of tectonic plates, which are now understood through the theory of plate tectonics. Ultimately, Wegener's hypothesis was overshadowed by more robust explanations involving mantle convection and plate boundaries.
What else can I help you with?
Wegener and idea that tidal forces might cause continental drift was refuted as impossible when research?
Alfred Wegener proposed that tidal forces could contribute to continental drift, but this idea was refuted when research demonstrated that the gravitational forces exerted by the Moon and Sun are insufficient to move large land masses. Subsequent studies in plate tectonics revealed that continental drift is primarily driven by the movement of tectonic plates due to mantle convection, slab pull, and ridge push, rather than tidal forces. These findings established a more robust scientific framework for understanding the dynamics of Earth's lithosphere.
Wegener idea that tidal forces might cause continental drift was retired as impossible when research?
Wegener's idea that tidal forces could drive continental drift was eventually dismissed due to a lack of empirical support and understanding of the forces involved. Research showed that the gravitational forces exerted by the Moon and Sun were insufficient to account for the massive movements of continents. Instead, the theory of plate tectonics emerged, providing a more robust explanation based on mantle convection and the interactions of tectonic plates. This shift in understanding rendered Wegener's tidal force hypothesis obsolete in the context of continental drift.
Why was weGenres hypothesis of continental drift not widely accepted at the time it was proposed what do scientists now think might be a possible cause of continental drift?
Alfred Wegener's hypothesis of continental drift was not widely accepted in the early 20th century primarily because he could not provide a convincing mechanism for how continents could move through the solid ocean floor. His ideas contradicted the prevailing geological theories, and many scientists were skeptical due to a lack of empirical evidence. Today, the theory of plate tectonics provides a robust explanation for continental drift, suggesting that the movement of tectonic plates, driven by forces such as mantle convection and slab pull, is responsible for the shifting of continents over geological time.
Could the earth's magnetic poles be the cause of continental drift?
No, the Earth's magnetic poles are not responsible for continental drift. Continental drift is primarily driven by the movement of tectonic plates in the Earth's lithosphere. The Earth's magnetic field does play a role in plate tectonics through magnetic stripes on the ocean floor, but it is not the primary cause of continental drift.
Tensional forces normally cause which one of the following?
Tensional forces typically cause objects to stretch or elongate.
Why was Alfred wegeners idea that tidal forces might cause continental drift refuted as impossible?
Alfred Wegener's idea that tidal forces could cause continental drift was refuted as impossible because tidal forces act on ocean water, not solid land masses. The forces required to move continents are much greater than those caused by tides. Additionally, there was no mechanism known at the time to explain how tides could cause such significant movement of continents.
Wegeners idea that tidal forces might cause continental drift was shown to be impossible when it was?
Wegener's idea was shown to be impossible when evidence of the mechanisms that actually drive plate tectonics, such as seafloor spreading and convection currents in the mantle, were discovered. These mechanisms provided a more comprehensive explanation for continental drift than tidal forces.
The first ship commissioned in the Continental cause was the?
The first ship commissioned in the Continental cause was the Alfred. It was a 30-gun frigate in the Continental Navy, authorized by the Continental Congress on November 4, 1775. The ship played a significant role in the American Revolutionary War, participating in various naval battles and operations.

Did continental-continental or oceanic-continental cause mount Everest?
If my sources are correct, it was made by continental-continental. :)
How did Alfred defeat the Danes?
Alfred the Great fortified his position, while the Vikings ravaged the countryside. This provoked a response by Alfred the Great, where he and his son lead an army to meet the Viking forces and defeat them. The second war involving the Vikings, Alfred the Great had fortified much of his kingdom. The Vikings invaded, but could not cause any real damage with the new fortifications. Alfred the Great ended up winning because of his fortified status.
Who is the scientist who first proposed that thermal convection in the mantle causes continental drift?
Alfred Wegener, a German meteorologist and geophysicist, proposed the theory of continental drift in 1912. He suggested that thermal convection currents in the mantle cause the movement of continents over time.

What forces cause strike slip fault?
The forces that cause strike slip faults are shearing forces. These forces refer to a pair of equally opposed forces.
Who did the Continental army surprise attack?
The Continental Army surprised attacked the Hessian forces in Trenton, New Jersey, on the morning of December 26, 1776. This surprise assault followed George Washington's famous crossing of the Delaware River on Christmas night. The attack resulted in a significant victory for the Continental Army, boosting morale and reinvigorating the revolutionary cause.
What do unbalanced forces cause according to Newton's Formula?
Unbalanced forces cause acceleration.
What can other forces do that frictional forces cannot do?
cause motion &+ cause positive acceleration . #
