what is the definition of the Continental Drift?
113672
geological theory that the relative positions of the continents on the earth's surface have changed considerably through geologic time. Though first proposed by American geologist Frank Bursley Taylor in a lecture in 1908, the first detailed theory of continental drift was put forth by German meteorologist and geophysicist Alfred Wegener in 1912. On the basis of geology, biology, climatology, and the alignment of the continental shelf rather than the coastline, he believed that during the late Paleozoic and early Mesozoic eras, about 275 to 175 million years ago, all the continents were united into a vast supercontinent, which he called Pangaea. Later, Pangaea broke into two supercontinental masses–Laurasia to the north, and Gondwanaland to the south. The present continents began to split apart in the latter Mesozoic era about 100 million years ago, drifting to their present positions.

but before pangaea there was a super continent called gondwanaland.\n\nIf you look at the Wilson Cycle, this is a cyclic process that has repeated itself a number of times.

The Geological definition would be a fracture along which there has been displacement relative to one another parallel to the fracture plane

Glacial drift: Till : moraine : Lateral moraines : terminal moraine\n\nGlacial drift is the loose and unsorted rock debris distributed by glaciers and glacial meltwaters. Rocks may be dropped in place by the melting ice; they may be rolled to the ice margins, or they may be deposited by meltwater streams. Collectively, these deposits are called glacial drift. Till refers to the debris deposited directly by the glacier. Rock debris rolls off the glacier edges and builds piles of loose unconsolidated rocks called glacier moraine. Lateral moraines form along the side of a glacier and curl into a terminal moraine.

When the super continent "Panacea" separated due to the activity of the techtonic plates, what became Europe and Africa drifted in the direction what would form the Americas

In 1915, the German geologist and meteorologist Alfred Wegener first proposed the theory of continental drift.

The tectonic plates are "floating" on a liqid mantle that has convection currents.  These convection move the plates around the globe.  This is the science behing plate tectonics

Tectonic plates are moving.

A good example of this is that scientists have found fossils of exactly the same species of reptile in Africa and South America, what happened here is that South America and Africa were once joined together and these animals died distributed on top of them, then the continents moved aprt and the fossils are on both\nThis isnt an example of evolutionary distribution due to continents moving but shows they do move and animals live on both of them\nNow what could happen is that a species could live on  continents joined together and as the continents drift apart the species are left on both sides of it and they evolve into separate but similar species ( like Humans and apes evolved form a common ancestor). \nSO the continets drifting explains why similar species can be on both sides of the Ocean that separates 2 continents because the continents drift apart with the species on both of them and the species evolve into 2 separate but similar species.

Pangea is a theoretical super-continent that existed millions of years ago and eventually broke up through platetechtonics to form the seven continents. I know old Albert had a few years under his belt, but not that many.

Coriolis effect, the apparent acceleration of a moving body on or near the Earth as a result of the Earth's rotation. An object at the Earth's surface moves faster at the equator--because it is moving through a 25,000-mile (40,000-kilometer) circle in 24 hours--than it does away from the equator, where it travels in a smaller circle in the same 24-hour period. The Coriolis Effect alters the paths of projectiles on Earth. Everything from jets to ships to bowling balls are affected by it.

The beginnings of the theory of plate tectonics date to around 1920, when Alfred Wegener, the German meteorologist and geophysicist, presented the first detailed accounts of how today's continents were once a large supercontinent that slowly drifted to their present positions. Others brought forth evidence, but plate tectonics processes and continental drift did not attract wide interest until the late 1950s, when scientists found the alignment of magnetic particles in rock responded to the earth's magnetic field of that time. Plotting paleomagnetic polar changes (see paleomagnetism) showed that all continents had moved across the earth over time.\n\nSynthesized from these findings and others in geology, oceanography, and geophysics, plate tectonics theory holds that the lithosphere, the hard outer layer of the earth, is divided into about 7 major plates and perhaps as many as 12 smaller plates, c.60 mi (100 km) thick, resting upon a lower soft layer called the asthenosphere. Because the sides of a plate are either being created or destroyed, its size and shape are continually changing. Such active plate tectonics make studying global tectonic history, especially for the ocean plates, difficult for times greater than 200 million years ago. The continents, which are c.25 mi (40 km) thick, are embedded in some of the plates, and hence move as the plates move about on the earth's surface.\n\nThe mechanism moving the plates is at present unknown, but is probably related to the transfer of heat energy or convection within the earth's mantle. If true, and the convection continues, the earth will continue to cool. This will eventually halt the mantle's motion allowing the crust to stabilize, much like what has happened on other planets and satellites in the solar system, such as Mars and the moon.

Divergent Boundaries...\n\nContinental/Continental: rift valleys i.e. East African Rift Valley\n\nOceanic/Oceanic: new crust is being formed on the ocean floor at oceanic ridges. The Mid-Atlantic Ridge is an example. The U.S. moves about 5cm away from Europe each year b/c of this.\n\nConvergent Boundaries...\n\nContinental/Continental: Both are of the same density & both are less dense than the molten material beneath so neither will be subducted. They form folded mountain chains such as the Appalachians of the U.S. & the Alps of Europe.\n\nContinental/Oceanic: Ocean crust is much denser & will be subducted under the continental. Friction from plate movement underneath the crust will cause melt & the crust will thin causing some volcanic mountains to appear.\n\nOceanic/Oceanic: One of the oceanic crusts will be subducted & a trench will be created. Volcanic island arcs are associated w/ this type of boundary.

The Gulf Stream, together with its northern extension, the North Atlantic Drift, is a powerful, warm, and swift Atlantic ocean current that originates in the Gulf of Mexico, exits through the Strait of Florida, and follows the eastern coastlines of the United States and Newfoundland before crossing the Atlantic Ocean

Plate tectonics\nFrom Wikipedia, the free encyclopedia\nJump to: navigation, search\n    \nBridge across the Álfagjá rift valley in southwest Iceland, the boundary of the Eurasian and North American continental tectonic plates.Plate tectonics (from Greek τέκτων, tektōn "builder" or "mason") is a theory of geology which was developed to explain the observed evidence for large scale motions within the Earth's crust. The theory encompassed and superseded the older theory of continental drift from the first half of the 20th century and the concept of sea floor spreading developed during the 1960s.\n\nThe outermost part of the Earth's interior is made up of two layers: above is the lithosphere, comprising the crust and the rigid uppermost part of the mantle. Below the lithosphere lies the asthenosphere, which is a more viscous zone of the mantle. Although solid, the asthenosphere has very low shear strength and can flow like a liquid on geological time scales. The deeper mantle below the asthenosphere is more rigid again.\n\nThe lithosphere essentially floats on the asthenosphere. The lithosphere has broken up into what are called tectonic plates—in the case of Earth, there are ten major and many minor plates. These plates move in relation to one another at one of three types of plate boundaries: convergent, divergent, and transform. Earthquakes, volcanic activity, mountain-building, and oceanic trench formation occur along plate boundaries. The lateral movement of the plates is typically at speeds of several centimetres per year.
