It is another example that helps scientists with their theory that all of Earth's landmasses (land) were/was once connected. WOOOOOOOOOT WOOOOOOOOOOT

Anu ang Continental Drift?
Continental Drift is a speculation made in 1596 by Abraham Ortelius. He stated that continents drift across the ocean bed.
The theory of plate tectonic suggest that?
This theory suggests that large, jigsaw like pieces of rock float on the upper mantle. It suggests that they fit together all over the planet, and are moving, though slowly at times. This theory was inspired by Alfred Wegner's theory of continental drift.
What technology did Alfred Wegener use?
The ascertations that Alfred Wegener posed with his Continental Drift theory pre-dated the technology necessary to prove his vision. In 1968 the new science of plate tectonics supported Wegener's theory.
What is the reason of the continental drift?
First, the continents do not drift! The theory of continental drift was based on observations of how the outlines of different continents appear to fit like pieces of a jigsaw puzzle and that when so fitted various ancient mountain ranges, etc. align from one continent to another. But for them to 'drift' they would have to 'plow' through the solid rock of the ocean floor, which is clearly not happening. The theory of continental drift was long ago discarded and replaced as new evidence was uncovered.The speculation that continents might have 'drifted' was first put forward by Abraham Ortelius in 1596. The concept was independently and more fully developed by Alfred Wegener in 1912, but his theory was rejected for lack of a mechanism.Following WW2 the US Navy made a series of observations showing symmetrical bands of magnetic field reversals on opposite sides of the midocean ridges. Because this information had value for military navigation, it was kept classified into the 1960s. When this information was made available to geophysicists, it confirmed key parts of the theory of plate tectonics (originally proposed in 1953).The idea of continental drift has been subsumed by the theory of plate tectonics, which explains how the continents appear to move. Convection currents in the semisolid mantle rock drag both continental and oceanic plates that float above the mantle around. The light granitic continental plate material tends to float higher, while the denser basaltic oceanic plate material tends to float lower so if they collide the continental plate will override the oceanic plate, causing it to subduct under the continental plate down into the mantle. If identical type plates collide the plates crumple and fold causing mountain ranges to form.The important thing to realize is the continents are not drifting, the tectonic plates (both continental and oceanic) of the crust are floating on the moving top surface of the mantle.
How does continental drift support plate tectonics?
continental drift and plate tectonics are two side of a coin. As the continents are interlinked with the plates; so as the plate moved due to conviction current the continents also tends to move causing continental drift. Moment of plates due to conviction current or due to the adjacent plate is called plate tectonics.
How does the Petoskey Stone help prove the theory of the continental drift?
When all the contents were together there was shallow water in Michigan so the Petoskey Stone was transferred to Michigan and that's how it supports the continental theory. hope this helps. ;-D
What theory replaced Wegener's hypothesis of continental drift?
I think that continetal drift replaced his theory
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 was the continental drift theory replaced by in 1967?
The continental drift theory was replaced by the theory of plate tectonics.
What is the volcanic and the drift continental theory?
the Continental Drift Theory is the slow movement of the Earths continents. A.K.A the continents drift
When you right continental drift does it have to be capitalized?
No, only Continental Drift Theory.
What theory did Alfred wegner introduce?
Alfred Wegener's theory was known as the theory of continental drift.
What ideas from the theory of plate tectonics add to the theory of continental drift?
earthquakes and volcanoes Do you know how to explain the theory of the continental drift?
Who proved continental drift?
Alfred Wegener Proved The theory of Continental Drift.
Who is the proponent of continental drift theory?
Alfred Wegener is the proponent or author of the Continental Drift Theory. lorzcute2000@yahoo.com
Did seafloor spreading prove the theory of continental drift?
Seafloor spreading helped prove the theory of continental drift. Pangea theory also helped.
The theory that continents can drift apart from oneanother?
Continental Drift
