The major issue in that regard was that Wegener did not have a plausible mechanism by which continents might move.

Why do you think that Wegener was unable to prove the theories of continental drift and plate tectonics before his death in 1930?
i think he was unable to prove his statements because he has never seen this happen
The term bankruptcy specifically refers to what?
being unable to pay debts and honor monetary commitments
What makes most of the Earth's water undrinkable?
The salt in it. Humans are unable to drink salt water.
Why are we unable to use fossil fuels forever?
They won't last forever. Once gone they are gone and they pollute the air.
Why can't sodium chloride conduct electricity in crystalline form?
Ionic compounds are unable to conduct electricity in crystalline (or solid) form because the ions are unable to carry the electric current since they cannot move from their fixed positions. When in a dissolved state, the ions separate and can thus carry the current.
Who was the first to say that continents drifted?
Francis Bacon noticed in 1620 that the outlines of the continents fit together like a jigsaw puzzle, but did not suggest a theory of why. Benjamin Franklin wrote in 1780 that the crust of the Earth must be a shell that can break and shift by movements of a fluid below The proper theory of continental drift was suggested by Alfred Wegener in the early 20th century. He published a book "The origin of the continents and oceans" proposing the existence of a supercontinent he called Pangaea about 250 million years ago. He was unable to explain a driving mechanism, which is one of the reasons why his theory was at first rejected by the scientific community.

What evidence did Alfred Wegener use to support his theory of continental drift?
Deep-sea mountain ranges had caught his attention. Alfred Wegener's fully developed theory of continental drift attempted to point out evidences that the continents were once joined into a single continent he called Pangaea. Wegener's theory hypothesized that the continents were able to push through the rock of the seafloor to their present positions. As evidence, he noted (as had others before him), of the geographic correlation in coastline perimeters of South America and Africa. This was the feature that led Wegener to investigate other clues. His investigations revealed that mountain ranges in South America and Africa, and strata and composition of coal fields in Europe and North America matched or lined up. Additionally, matching reptilian fossils were found on either side of the ocean, indicating that the continents were once joined together. Although he was unable to find a mechanism for his proposed continental drift theory, he also observed that the more shallow an ocean, the younger its geologic age. It wasn't until the 1950's and 1960's, with the discovery of the Mid-Atlantic Ridge (and other sea floor mapping discoveries) that Wegener's hypothesis started to become more accepted. The newer science of plate tectonics owes much to Wegener's scientific groundwork. sdhtshehdtubt6yhsx ryjut7iyldrtysvefgb 6u fyu6uerjthe5tjkj jgyuftyk
What was Alfred Wegener's first presented idea of continental drift?
In 1915 the first edition of The Origin of Continents and Oceans, a book outlining the Continental Drift theory of Alfred Lothar Wegener, a German meterologist, was published; expanded editions were published in 1920, 1922, and 1929. About 300 million years ago, claimed Wegener, the continents had formed a single mass, called Pangaea (from the Greek for "all the Earth"). Pangaea had split, and its pieces had been moving away from each other ever since. Wegener was not the first to suggest that the continents had once been connected, but he was the first to present extensive evidence from several fields. He was subsequently proved right, although he was wrong in one respect; the continents don't drift on their own, they move as part of much larger "plates" of the Earth's surface, much of which is ocean floor.

One of the main objections to wegner's hypothesis of contental drift was that he was unable to provide an acceptable?
One of the main objections to Wegner's hypothesis of continental drift was that he was unable to provide a plausible mechanism to explain how continents could move across the Earth's surface. Additionally, the scientific community at the time did not have a clear understanding of plate tectonics, which is the driving force behind continental drift. It wasn't until later that plate tectonics was accepted as a valid scientific theory, providing the mechanism needed to support Wegner's ideas.
What is one of the reasons Alfred Wegener believed Earth's continents once formed a single massive supercontinent?
Observations of a map of the continents hinted that the continents once fitted together. Later, he would discover fossil evidence to support his theory. But alas, he was unable to explain the mechanism by which the continents could move, and was soundly thrashed by geologists of his time. The discoveries leading to the science of plate tectonics were not made until the mid twentieth century.
What evidence did wegner have for continental drift theory?
Actually there is a lot of evidence that supported his evidence the big one was fossils of animals on distant continents and plants for example Glossopteris was one the strange reasons that Alfred was more than ever to prove his point.Edit:Alfred Wegener proposed that, using 19th century longitude determinations, Greenland had moved 1 mile away from Europe. However, this conclusion ended up being false due to false calculations. Still, Wegener discovered that every year San Diego moved 6 feet closer to Shanghai while Washington D.C. and Paris got 15 feet closer. In addition, Alfred Wegener discovered that related species, too small to swim across the ocean, were found on different continental plates, as well as similar fossils.Alfred Wegener's theory was rejected at first, however, because he was unable to explain the reason why the plates moved. Later, Arthur Holmes published his theory of thermal convection being the the thing that drove the plates apart. He also noted that the continents didn't "move" but were "carried" by larger pieces of the Earth's crust. Discoveries of the Mid-Ocean Ridge in addition to Harry Hess's work adds onto this theory of Wegener's.As this theory is the most complete theory concerning global dynamics, the roots of such lie in the curiosity and work of Alfred Wegener.
