South America Africa India and Australian continents are believed to be moving away from the central Antarctica continents by sea floor spreading process is proved to be wrong.
researchers who believe that all the continents are moving also believe that new sea floor is being formed at the Central region of the Atlantic ocean.a process which the called sea floor spreading .
according to them new sea floor is formed in that region by upwelling magma which surfaced and cooled and solidified and finally formed new sea floor rock.as the process continue new sea floor rocks are formed in the central region which pushing the old sea floor rock to the side.
therefore the sea floor is moving in opposite direction therefore the continents of south America and Africa which is said to be on the moving plate also moving in opposite direction(east-west).
this kind of sea floor spreading can be called as longitude spreading since all the longitude have same length.so there is no problem in this kind of explanation.
but the researchers who believe that all the continents are moving on the surface of the earth also believe that South America Africa India and Australian continents are moving away form the central continent of Antarctica.
and the researchers believe that the Antarctica continents is surrounded by sea floor centre where new sea floor is formed and spreading toward the north therefore the southern continents which rest on the moving plate also moving towards the north i.e moving away from the central Antarctica.
but in this case unlike the longitude spreading the latitudes are having different length.
particularly the latitude near the south pole i.e just around the central Antarctica is smaller then the northern latitudes which is near the equator.
therefore if new sea floor is formed around the Antarctica as the researchers believed and moved towards the north then huge gap will be formed around the central continent of Antarctica.
therefore the newly formed sea floor can not carry huge continents and move along with huge continents as a single plate.
therefore this sea floor spreading model around the Antarctica is proved to be wrong as well as the notion of the moving of the southern continents also proved to be wrong.
particularly rock plate which is formed at the small circumference area can not have the strength to pushing the rock plate which is occupying larger surface area.therefore the said explanation i.e newly formed rock plate moving northward direction which is also said to be carrying the huge continents is not possible.

In this map many arrow mark with numbers marked along the so called continental plate margin which indicating the spreading rate of the continental plate.
but the spreading rate of the continental plate is differ from pl...ace to place on the same continental plate margin.
if this is the case then the continental plate can not move as a single plate.
therefore it is not correct to say that the continents are moving as a single plate.
IF The spreading rate of continental plate is vary from place to places then how can the continents move as a single plate?
