State the hypothesis of continental drift?
That there was once a super continent called Pangaea huge land mass was broken into continents that drifted apart. The theory also suggests that the earth is made up of 7 gigantic shifting slabs of the earth's crust. This disproved the more popular (at the time) "raisin" theorem
Why is the continental drift not a theory but a fact?
because the continents keep moving every day, that is how the continents got the way they are right now.and they will keep on moving a continental drift is when the continents were all joined together and they use to call it panagaea. one day the continents started to spleet up into two continents and they were call gondwana and laurasia. after a few years they started to separate into groups. so a continental drift is when continents are moving. for example every year it Australia move 5 cm.
A short paragraph about continental drift?
First of all continental drift happened after Pangea. Pangea was a time when all of the continents were formed together. Then platetectonics moved which caused earth quakes. The earth quakes made the continents drift, and is called continental drift. To learn more on continental drifts and plate tectonics visit http;//www.infoplease.com/ipa/A0001765.html
Describe continental drift theory?
continents move about as plates of crust and upper mantle, on more mobile layer of asthenophere in the mantle. Movement driven by mantle convection and isostasy. Bumps between continents = mountain chains bump continental with oceanic = island arc vocanoes and subduction of oceanic plate
What three continents came together to form Pangaea?
It wasn't three continents it was all of them.
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.

Wegener continental drift hypothesis stated that all the continents were once joined together to form?
A super continent called Pangaea.
What is Wegeners hypothesis?
Wegener hypothesized that, on earth, there was only one continent called Pangea, but it split into the continents we have now.Improved Another Answer:Wegener's hypothesis was that long 225 million years ago, there was a supercontinent called Pangaea (All the continents were all together).Wegener saw that South America and Africa looked like they could fit together like puzzle pieces. He then found that there were fossils of animals in a warm climate and it was also in a very cold climate. He thought, "How could that be? The animal couldn't have lived in two different kinds of climates and how could it have swam across the sea?!"
What were Charles Darwin's contributions to Wegeners theory of continental drift?
Most people actually state that Darwin beat Wegener to the theory of continental drift as he mentioned in most of his studies about the continents drifting apart and fitting together.
Give an example of evidence from land features that supported wegeners idea of continental drift?
An example of evidence from land features that supported Wegener's idea of continental drift might include the piecing together of map layouts which show the way that the continents fit together. Wegener is famous for sharing this example.
What was an important reason why wegeners continental drift hypothesis was widely accepted?
The continental Coastlines fit together like puzzle pieces, fossils, and glacier Grover in warm places
What evidence caused Alfred Wegener to develop his hypothesis of continental drift?
One of His Theorys of continental drift was, that you could fit the continents back together if you had pictures. Also it would make up Pangea
What was alfred wegeners hypothesis about continental drift?
States that the continents were once a single huge landmass. This landmass broke up million years ago and the pieces drifted apart. facing edges of many continents have similar rock formations. If the continents brought togehter, the formations would match exactly (like combining South America and Africa). Fossils of the same kinds of living things have been found on different continents. Perhaps these living things were together on one landmass before it split.
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.
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 evidence is there to show that the continents were joined together?
Evidence for the continents being joined together in a supercontinent, called Pangaea, includes similar fossil and rock formations found on different continents, the alignment of mountain ranges and geological structures when continents are pieced together like a jigsaw puzzle, and matching coastlines and continental shelves that fit together like a puzzle. Additionally, evidence from paleoclimatology, the study of past climates, supports the theory of continental drift.
