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.

Alfred Wegener used several pieces of evidence to support his theory of continental drift, including the jigsaw-like fit of continents, matching rock formations and mountain ranges across continents, and the distribution of fossil species across continents that were once connected. He also looked at the similarities in geologic structures and ancient climates found on different continents.

Who proposed the continental drift theory in the 1900?
Alfred Wegener
Why didn't the scientific world believe Alfred Wegener and continental drift?
Lack of evidence
True or false wegener knew that continental drift explained fossils of tropical plants?
True. Alfred Wegener, the scientist who proposed the theory of continental drift, used the distribution of fossils of tropical plants across continents as evidence to support his idea that the continents were once connected. This was one of the key pieces of evidence Wegener used to support his theory.
What evidence did Alfred wanger use to support his theory of contnetal drift?
Alfred Wegener used several lines of evidence to support his theory of continental drift. This included the fit of the continents like a jigsaw puzzle, similarities in rock formations and mountain ranges across different continents, matching fossils on separate continents, and paleoclimatic evidence such as glacial striations in tropical regions. These pieces of evidence led Wegener to propose the theory of continental drift in the early 20th century.
How many expeditions did Alfred wegener go on?
Alfred Wegener went on four expeditions to Greenland between 1906 and 1930. His expeditions involved studying glaciers, geology, and meteorology to gather evidence to support his theory of continental drift.
Which type of evidence was not used by Alfred wegener to support his continental hypothesis?

What types of evidence was used by Alfred Wegener to support his continental drift hypothesis?
human remains
What evidence of land feautures did Alfred wegener use?
Alfred Wegener used various pieces of evidence to support his theory of continental drift, including the fit of the continents, rock and fossil similarities across continents, glacial evidence, and similar geological features on different continents.
Why is the continental drift theory a theory and not a scientific law?
The Continental Drift theory is a theory because there is no evidence to support it. Alfred Wegener developed the Continental Drift theory in the 1800's.
What 3 pieces of evidence did Alfred Wegener use to support his theory of continental drift?
he used fossils, glacial indentations, and different types of rock.
Who proposed the continental drift theory in the 1900?
Alfred Wegener
Why didn't the scientific world believe Alfred Wegener and continental drift?
Lack of evidence
What was the name of Alfred Wegener's support of continental drift?
Alfred Wegener's support of continental drift was known as the theory of "continental drift," which proposed that the continents were once joined together as a single supercontinent called Pangaea and have since drifted apart.
True or false wegener knew that continental drift explained fossils of tropical plants?
True. Alfred Wegener, the scientist who proposed the theory of continental drift, used the distribution of fossils of tropical plants across continents as evidence to support his idea that the continents were once connected. This was one of the key pieces of evidence Wegener used to support his theory.
What did Alfred Wegener use for evidence?
Alfred Wegener used several pieces of evidence to support his theory of continental drift, including the fit of continents like South America and Africa, similar rock formations and mountain ranges across continents, and the distribution of plants and animals. He also looked at evidence from fossils and ancient climate data to support his hypothesis.
Which was used by Wegner to establish the continental drift?
Alfred Wegener used evidence from the fit of continents, distribution of fossils, rock types, and ancient climate data to support his theory of continental drift.
