Let us talk something about super continent Gondwana and it's breaking in the continents which we see today on map.
Gondwana ,around 336 to 175 million years ago existed on planet Earth.
Altered venger ,gave hypothesis that ,the one super continent was broken down in several land masses and drifted away.
Yes ,the evidences of fossils and ,sea floor opening and may be increase in height of mountains may indicate this.
However the basic question is How did ti break in first place.
It is believed that the hot plumes of lava may have caused rupture in this supercontinent .
There were numurous such supercontinents prior to this , like Vaalbara ( 3636 million years ago) ,Ridings and Pannotia.
For our study we will consider the last supercontinent, ie Gondwana
1) Scene 1.
The Earth stated cooling off and upper crust has started forming ,say in the Shape of Gondwana at the location where ,we believe it existed
Or from its earlier version Pannotra ( 633 million years to 573 million years)
2) Scene 2
The hot plume of magma from beneath this Gondwana ,broke it in to pieces which started drifting away. The continents seen as today are finally arrived at
Now the question s are
1) Whether the hot plumes of magma was there earlier to formation of Gondwana ? Or it started later
2) If it was there earlier ,and active, it would have nit allowed the formation of Supercontinent there
3) And if it( the hot magma plume) was not there active , how and why did it started later .
The correct explanation is like this
Yes ,there are plates and they are moving, and quake generally occur on plate boundaries , but because the plate boundaries are weaker cross section and tidal pull can break it first
Explanation
1) The super continent Gondwana broke away due to violent quakes and violent eruptions induced due to
execcessive tidal pull on potent dates.
2) The broken away continents then drifted away ,to the upper latitudes, due to rotation of Earth on the axis.
It may please be noted that ,there is minimum land mass along Equator and more land masses as you move towards poles. This is due to rotation of Earth .The floating plates moves away from center and hence away from Equator.
The proof is ,Indian subcontinent, being small in size ,moved much faster towards North, due to Earth rotation
So bottom line is
a) The Gondwana was broken due to violent quakes and violent eruptions both due to excessive tidal pulls .
b) These continents are moving away towards poles ,both north and south due to Earth rotation on axis
c) These continents will never comeagain at Equator as predicted by scientists.They will move towards poles and concentrate at both poles.
