Alfred Wegener's Theory?
Alfred Wegener proposed the theory of continental drift in the early 20th century, suggesting that continents were once connected and drifted apart over time. His theory was met with skepticism at the time but laid the foundation for the modern theory of plate tectonics. Wegener's ideas were supported by evidence such as the fit of continental coastlines and the distribution of fossils across continents.
What is continental drift theory by Alfred?
The theory of continental drift, proposed by Alfred Wegener in 1912, suggests that continents were once joined together in a single supercontinent called Pangaea and have since drifted apart. This theory laid the foundation for the modern theory of plate tectonics, which explains the movement of Earth's lithosphere. Wegener's theory was initially met with skepticism but has since been supported by overwhelming geological and paleontological evidence.
What period of time was evidence supporting continental drift?
The evidence supporting continental drift emerged in the early to mid-20th century, with key contributions from scientists like Alfred Wegener and Arthur Holmes. By the 1960s, advancements in technology, such as ocean floor mapping and paleomagnetism, provided further support for the theory.
How long was it before new evidence emerged to support wegener's original theory?
It took several decades before new evidence emerged to support Wegener's original theory of continental drift. In the 1960s, significant discoveries such as seafloor spreading and plate tectonics provided strong evidence to confirm Wegener's ideas. This eventually led to the widespread acceptance of the theory of plate tectonics in the scientific community.
Why did Wegener's idea get rejected by scientists?
Scientist rejected Wegners hypothesis of continental drift at first because he did not have enogh evidence to support his theory. He failed to provide a suitable mechanism that could cause the continents to move.
Alfred Wegener's Theory?
Alfred Wegener proposed the theory of continental drift in the early 20th century, suggesting that continents were once connected and drifted apart over time.

Wegener's ideas were supported by evidence such as the fit of continental coastlines and the distribution of fossils across continents.
Why did people not believe the continental drift theory when Alfred wagener first explained it?
When Alfred Wegener first proposed the continental drift theory in the early 20th century, it was met with skepticism because he did not have a mechanism to explain how the continents moved. Additionally, Wegener's idea challenged long-established geological theories and faced resistance from scientists who were reluctant to accept a new paradigm. It wasn't until the development of the theory of plate tectonics in the 1960s that Wegener's ideas gained widespread acceptance.
How long did Wegener think it took for the supercontient to break apart and form the positions your content?
Alfred Wegener proposed the theory of continental drift, suggesting that the supercontinent Pangaea broke apart over a period of 200 million years, with the continents gradually moving to their current positions. Wegener's hypothesis laid the groundwork for the modern theory of plate tectonics.
Why was wegener's hypothesis not widely accepted at the time it was prospered?
Wegener was ignored for so long because no scientists believed him about his theory of continental drift. No scientists believed him because he couldn't explain how the continents had moved until the time of Harry Hess or J. Tuzo Wilson.
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.

When did Alfred the great become king?
Alfred the Great became king in 871 to 899 (long long ago)
When was Alfred Piccaver born?
Alfred Piccaver was born on February 24, 1884, in Long Sutton, England, UK.
How long was it before new evidence emerged to support wegeners theory of the continental drift?
New evidence supporting Alfred Wegener's theory of continental drift began to emerge in the late 1940s and early 1950s, approximately 30 years after he first proposed the theory in 1912. The development of plate tectonics, particularly the discovery of seafloor spreading and paleomagnetism, provided crucial evidence that validated Wegener's ideas. This shift in understanding revolutionized geosciences and established a comprehensive framework for explaining the movement of continents.

The evidence supporting continental drift emerged in the early to mid-20th century, with key contributions from scientists like Alfred Wegener and Arthur Holmes. By the 1960s, advancements in technology, such as ocean floor mapping and paleomagnetism, provided further support for the theory.
How long did it take Alfred Nobel to make dynamite?
how long did it take Alfred Nobel to make dynmite
How did Alfred wegener hypothesize that long ago the continents were just one big land mass and hot separate as they appears to be today?
He looked at a map and noticed that the west coast of Africa and the east coast of South America appeared to fit together like pieces in a jigsaw puzzle. The then began to see other continental coastlines that apparently fit together.
