The Mid-Atlantic Ridge is...?
435645
A, because it's the division between two tectonic plates. the plates move apart and magma from inside the earth comes up and piles up in the form of mountains.

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

The best answer from the above choices: \nSlow moving convection currents within the molten aesthenosphere supply new material to the spreading centers in the earth's ocean floors and other places. These currents are thought to provide force to cause the motion of the oceanic plates, either directly, or indirectly through the mid ocean ridge building process. \n\nSubduction is only one part of the process of plate tectonics, that does provide some driving force by pulling the subducting plate downward. \n\nGravity has a role as well, as without gravity, the mid-ocean ridges would not have the weight to provide force with which to push the plates apart at the spreading centers, and the subducting plates would not have the force to pull plates. \n\nThe earth's magnetic field may have the least to do with plate tectonics, possibly no role at all.

4 ways:\n\nDivergent plate boundaries\nAt the mid-oceanic ridges, two tectonic plates diverge from one another. New oceanic crust is being formed by hot molten rock slowly cooling down and solidifying. In these places, the crust is very thin and eruptions occur frequently because of the pull by the tectonic plates. The main part of the mid-oceanic ridges are at the bottom of the ocean, and most volcanic activity is submarine. Black smokers are a typical example of this kind of volcanic activity. Where the mid-oceanic ridge comes above sea-level, volcanoes like the Hekla on Iceland are formed. Divergent plate boundaries create new seafloor and volcanic islands, such as Cjertce and Hawaii.\n\nConvergent plate boundaries\nIn places where one tectonic plate submerges beneath another, the crust melts and becomes magma. This surplus amount of magma generated in one location causes the formation of the volcano. Typical examples for this kind of volcano are the volcanoes in the Pacific Ring of Fire, and also Mount Etna and Mount Vesuvius.\n\nHotspots\nHotspots are not located on the ridges of tectonic plates, but on top of mantle plumes, where the convection of Earth's mantle creates a column of hot material that rises until it reaches the crust. The temperature of the plume causes the crust to melt and form pipes, which can vent magma. Because the tectonic plates move whereas the mantle plume remains in the same place, each volcano becomes extinct after a while and a new volcano is then being formed as the plate shifts over the hotspot. The Hawaiian Islands are thought to be formed in such a manner, as well as the Snake River Plain, with the Yellowstone Caldera being the current part of the North American plate over the hotspot.\n\nPetitspots\nIn July 2006, volcanoes were discovered that did not fit in any of the above-mentioned categories, since they are located far from the plate boundary, but are too small to be the result of a mantle plume. A new theory suggests that submergence of tectonic plates causes stress all over the plate, which causes the plate to crack in some places. However, other scientists believe the mantle plume theory to be incorrect, and consider this discovery a confirmation of their ideas.

Yes, continental drift is still happening.  A typical comparison is that the expansion of the mid-Atlantic ridge is causing the two sides of the Atlantic ocean to move apart at about the rate your fingernail grows, or about 3cm a year.\n\nThe Indian Ocean tsunami of December 2004 was caused by the eastern edge of the India plate sliding under the Burma plate in what's called subduction zone.  For a couple hundred years, the friction between the two plates caused the lip of the Burma plate to gradually bend down.  On 12/26/2004, about 750 miles of the seam between the slipped free, and the bent-down lip of the Burma plate snapped upwards about 50ft, causing the tsunami.

It is a PLAIN (a large flat area) next to the coast of the Atlantic Ocean. It goes from New Jersey down to Georgia for a variable distance in from the ocean - 100 to 300 miles.

Actually, it is the Atlantic, which divides Africa from South America.  These two continents used to be connected.  There is a large volcanic ridge in the centre of the Atlantic which extends all the way to Iceland,  New rock is formed at this ridge where the Earth's crust is thin.  Convection in the liquid interior of the earth is pushing the two sides away from each other.  When the new rock solidifies at this ridge, the magnetic minerals within it align themselves with the Earth's magnetic field.  Over many millions of years, the North and South Magnetic poles actually reverse!  Thus when survey ships using magnetometers were searching for oil in the atlantic, they noticed stripes of magnetism in the atlantic ocean.  The stripes were equal on both sides of the ridge.  This was one of the pieces of evidence that supported plate tectonic theory.  Now there are lasers set up on either side of the spreading ridge in Iceland showing that Iceland, and the Atlantic ocean are growing.
