The continental drift theory is the theory that once all of the continents were joined in a super-continent, which scientists call Pangaea. Over a vast period of time, the continents drifted apart to their current locations.

What is descent with modification?
Descent with modification encapsulates the two key ideas central to the theory of evolution. These are that modifications (mutations) occur, and that these mutations are inheritable (passed on to descendants or offspring).
What key evidence did Alfred Wegener use to support his hypothesis of continental drift?
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 Pangea. 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 for other evidences. 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.

What is the the continental drift theory?
Continental drift refers to the movement of the Earth's continents relative to each other. The theory was first proposed by Frank Bursley Taylor in 1908, at a meeting of the Geological Society of America. Prior to this, various notable scientists such as Abraham Ortelius, Francis Bacon, Antonio Snider-Pellegrini and Benjamin Franklin had observed that the shapes of continents on either side of the Atlantic Ocean seemed to fit together. The theory that all the continent had originally been part of a supercontinent - now referred to as Pangaea - was also supported by the similarities of fossil remnants and some geological formations across the southern continents.The first to use the term continental drift was Alfred Wegener. He proposed that the cause of continental drift was the continents being been pulled apart by the centrifugal force of the Earth's rotation, but this was considered unrealistic by other scientists. In the 1960s, geological research suggested the theory of plate tectonics, which accounted for the theory of continental drift. Continental drift was a theory that explained how continents shift position on Earth's surface. Set forth in 1912 by Alfred Wegener, a geophysicist and meteorologist, continental drift also explained why look-alike animal and plant fossils, and similar rock formations, are found on different continents. Wegener thought all the continents were once joined together in an "Urkontinent" before breaking up and drifting to their current positions. But geologists soundly denounced Wegener's theory of continental drift after he published the details in a 1915 book called "The Origin of Continents and Oceans." Part of the opposition was because Wegener didn't have a good model to explain how the continents moved apart. Though most of Wegener's observations about fossils and rocks were correct, he was outlandishly wrong on a couple of key points. For instance, Wegener thought the continents might have plowed through the ocean crust like icebreakers smashing through ice. "There's an irony that the key objection to continent drift was that there is no mechanism, and plate tectonics was accepted without a mechanism," to move the continents, said Henry Frankel, an emeritus professor at the University of Missouri-Kansas City and author of the four volume "The Continental Drift Controversy" (Cambridge University Press, 2012). Although Wegener's "continental drift" theory was discarded, it did introduce the idea of moving continents to geoscience. And decades later, scientists would confirm some of Wegener's ideas, such as the past existence of a supercontinent joining all the world's landmasses as one. Pangaea was a supercontinent that formed roughly 300 million years ago, and was responsible for the fossil and rock clues that ledThe continental theory is when theory separates the colonist. This was made in the year 1912.

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.
What are key ideas?

What does key ideas mean?
The main ideas or themes. Imagine the subject is a tree. The key ideas is the trunk. The secondary ideas or themes would be the branches that come off the key ideas. All of those secondary ideas originally come from the key ideas.

What arguments were used against Wegener's theory of continental drift?
Alfred Wegener proposed the theory of continental drift. His evidence included the fit of the continents, similar fossils on different continents, glacier evidence in Australia, and the alignment of mountain ranges in America and England.The theory of plate tectonics followed the continental drift theory. Plate tectonics had the advantage of proposing a mechanism for the movements of the continents, and was accepted. The key piece of evidence was seafloor spreading, relating to magnetic striping near ocean ridges.Plate tectonics is the theory that Earth's crust consists of seven large plates and many smaller plates shifting around on Earth. The movement of these plates creates Earth's features, such as ridges, mountains and some of the volcanoes.Earth's mechanical layers are the lithosphere, asthenosphere, mesosphere and core. The hard lithosphere floats on top of the soft asthenosphere.Subduction occurs at convergent boundaries. Here, ocean crust is destroyed when it is pushed under continental crust. New crust is formed at divergent boundaries, such as ocean ridges. A transform boundary is where two plates slide past each other horizontally.It was originally thought that simple convection cells in the mantle caused the plate movement. Now it is thought that slab-pull is the dominant force. Other factors are slab-push and hot plumes.Pangaea was the super-continent that formed about 300 million years ago, and contained all of the continents. It broke up due to heat build-up. It is thought that several super-continents have existed in Earth's past.
