What is an explanation that ties together many hypothesis and observations?
theory
What hypothesis by Alfred Wegener explains why continents seem to fit together?
plate tectonics
What was Wegener's hypothesis of continential drift?
the continents were once joined together in a single landmass
What evidence supports wegener's hypothesis?
All of the continents fit together like a puzzle.
What observations led to Alfred wegener to develop the hypothesis of continental drift?
The observation that led Alfred Wegener to develop the hypothesis of continental drift was that the continents looked like a puzzle that could fit together and then found out that fossils of similar kind and whats left of similar plants were found on opposite sides of the world.
What Alfred wegners hypothesis?
He discovered Pangaea; once all the continents were together, as one big continent.
Wegener's continental drift hypothesis stated that all the continents were once joined together to form what?
A super continent called Pangaea.
Wegener continental drift hypothesis stated that all the continents were once joined together to form?
A super continent called Pangaea.
What hypothesis states that the continents were once continents were once joined to form a single super continent?
If put together, they would fit perfectly into one huge super continent like a puzzle.
Why is continental drift called a hypothesis?
the Hypothesis is Based on an apparent fit between Africa and South America,Wegener hypothesized that at one time all continents were joined together in a "supercontinent" called Pangaea. The supercontinent eventually broke into the smaller continents, which then "drifted" towards their present positions.
How did discovery of glossopteris support Wegeners continental drift hypothesis?
Because identical fossils were found on two continents far apart, it suggested that at one time the two landmasses were joined together. In other cases of lands separated by far less distance, plants did not propagate across the divide.
