Hypothesis of plate movements

 Yes ,that is what I am trying to say.

The plates move away from Equator towards less rotation (angular) speed. Slowly at pole their speed reduces /approches to zero.

  This is why we have less land mas ar Equator. 

  You can see more small plates ,which are moving faster near Equator, but only one big plate at poles ,which is nearly at stand still.

 You can see more plate boundaries and more quakes between + and - 30 degree lattitudes. This is because the Moon , Sun and planets have maximum declination 27 degree north or south.

  I also ,dare to say that plates have only two movements 

1) Above Equator it moves towards North, North East. All those plates whose 50%+ land mass is above Equator moves towards ,North East, due to Earth rotation 

2) All those plates whose 50%+ land mass is below Equator  moves towards South, South-west ,till they reach south pole or obstructed before reaching south pole.

3)I also say that,two plates never move against each other.When one reaches near poles ,the plate below it pushes it.It is always one way push.In northen/southern hemisphere two plates can not move in opposite direction.What we see is one at standstill and another pushing it

4) what we see divergent plates are ,one stand still (or nearly at stand still -like south pole big plate ,the upward moving plates creates a gap ,like Indo Australian plate

These are my hypothesis
