From one super continent (Pangea) to their present postitions (they are still moving) is Continental Drift. It wasn't until the 1960s that scientists infact named it 'Plate Tectonics'. - earth's crust is made up of a number of large, rigid plates - these plates floats on the mantle - mantle contains convection currents that cause the molten fluid to move and circulate - causing the floating crust above to move - plates can therefore move around - about 1.5 inches per year
The tectonic plates on the earths crust are constantly shifting because of gravity, so after over millions of years, they shifted into their current positions. the ocean is simply water levels, that fill up the more deep sections in the earths crust. the water level is directly related to temperature. if there are no glaciers, the water is free and the levels rise. if it is cold and there are glaciers, then the water level will lower as it is all tied up in glaciers.
It is called the continental drift. In 1960 scientists renamed it plate tectonics.

continental drift or plate tectonice
continental drift
yes he did he explained that the continents fit like a puzzle but the scientist did not believe him because he could not explain "how"
Because he could not explain how the continents moved.
He could not provide a wholly acceptable explanation for the movement of the continents.
Wegener couldn't explain how or why continents moved.
Alfred Wegener also came up with a theory to explain continental drift, although it was in error. His theory of continental drift proposed that centrifugal force moved the heavy continents toward the equator as the Earth spun. He thought that inertia, from centrifugal movement combined with tidal drag on the continents (caused by the gravitational pull of the sun and moon) would account for continental drift.I think the sentence in italic and bold is the answer...~anonme~!danah!
Continental drift :)
no.i think it doesnt.
it explains y there is volcanoes, earthquakes, and the movement of the continents
they move because they grow bigger and move side to side
yes he did he explained that the continents fit like a puzzle but the scientist did not believe him because he could not explain "how"
He could not explain why the continents drifted.
Continental drift is the movement of the earth's continents across the ocean's bed relative to one another. There is no disadvantage as such of this theory however it has certain weaknesses. One of the weakness is that people could not explain the forces that caused these continents to move such great distances.

when continents collide you bum your pet hamster
because when the atoms meet up in the gases they separate and form more gases of matter. that's basically it!

explain why similar plants and animals found in the continents of africa , south america,australia and india
