Why was the hypothesis of continental drift rejected when it was proposed by wegener?
Wegener's hypothesis of continental drift was rejected because he lacked a plausible mechanism to explain how the continents moved. Additionally, the scientific community at the time did not have sufficient evidence to support the idea of continents drifting. It wasn't until the theory of plate tectonics emerged later, providing a mechanism and supporting evidence, that continental drift became widely accepted.
Describe the relationship of continental drift and plate tectonics?
Continental drift is the theory that the Earth's continents have moved over time due to the movement of tectonic plates. Plate tectonics is the scientific theory that describes the large-scale movements and interactions of Earth's lithosphere. Continental drift was one of the key pieces of evidence that led to the development of the theory of plate tectonics.
What evidence at first for the hypothesis of continental drift and later for the theory of plate tectonics?
The initial evidence for the hypothesis of continental drift, proposed by Alfred Wegener, included the complementary shapes of continental coastlines, particularly South America and Africa, as well as fossil correlations and geological similarities across continents. Later, the theory of plate tectonics gained support from the discovery of mid-ocean ridges, the pattern of seismic activity along tectonic boundaries, and the age of ocean floor rocks, which demonstrated seafloor spreading. Additionally, paleomagnetic data revealed the historical movement of continents, providing further validation for the dynamic nature of Earth's lithosphere.
Did Alfred Wegener use sea-floor spreading ridge push and slap pull to develop his hypothesis of continental drift?
No, Alfred Wegener did not use sea-floor spreading, ridge push, or slab pull to develop his hypothesis of continental drift. Wegener proposed his theory in 1912, long before these concepts were formulated in the mid-20th century as part of the theory of plate tectonics. Instead, Wegener based his hypothesis on evidence such as the fit of continental coastlines, fossil distribution, and geological similarities across continents. The mechanisms of sea-floor spreading and plate tectonics were developed later to explain the movement of continents.
What is wegeners hypothesis for continental drift?
Wegener's hypothesis for continental drift, proposed in the early 20th century, suggests that continents were once part of a single supercontinent called Pangaea, which gradually broke apart and drifted to their current positions. He based his hypothesis on evidence such as the fit of continental coastlines, similar geological features across continents, and fossil correlations. Despite presenting compelling evidence, Wegener's theory was initially met with skepticism due to the lack of a mechanism to explain how continents could move. It wasn't until the development of the theory of plate tectonics that his ideas gained widespread acceptance.

What was not used in support of the continental drift hypothesis?
One key piece of evidence that was not initially used in support of the continental drift hypothesis was a mechanism explaining how continents could move. It wasn't until the discovery of plate tectonics and the development of the theory of seafloor spreading that a mechanism was found to explain how continents drift.

What was the reason wegeners continental drift hypothesis was rejected?
His evidence was incorrect.
What evidence supported hypothesis of continental drift?
Tropical fossils in Antarctica.
Which one of the following was NOT presented by Alfred wegener as evidence of continental drift?
Alfred Wegener presented several pieces of evidence for continental drift, including the fit of the continents, fossil correlations, and geological similarities across continents. However, he did not present the concept of plate tectonics, as this theory was developed later to explain the mechanisms behind continental drift. Therefore, any evidence specifically related to plate tectonics would not have been part of Wegener's original arguments.
What did scientists change the name of wegeners hypothesis to?
Scientists changed the name of Alfred Wegener's hypothesis of continental drift to the theory of plate tectonics. This shift occurred as a result of accumulating evidence and advancements in understanding the Earth's lithosphere, which is divided into tectonic plates that move and interact. Plate tectonics encompasses not only the movement of continents but also the mechanisms driving these movements, such as seafloor spreading and subduction.
