We have seen time and again that the set norms ,ideas by science are very difficult to change. whether it is the idea that Earth is ge Center of universe or that the Earth is flat.
The bottom line is ,if the theory which we believe, does not serve the basic purpose, we need to look outside the theory.
One such theory is plate tectonics.
A lot many questions it can not answer ,forget prediction of quakes.
Why are we so stubborn, not to have a look at other theories.
On seemingly signals we have accepted this theory
What if I say..
Yes ,there are plates and they are moving and that 90% quakes occur at plate boundaries but...
1) Plates are due to Quakes and that ,quakes are not due to plates
2) Quakes occur at plate boundaries because those are weaker sections and tidal pull can break it first
3)Plates are moving due to Earth rotation and not due to convection currents
4) Plates try to move away from Equator to poles, that is why we have negligible land mass at equator and huge chunks at poles
5) Speed of plates is more near Equator and less near poles ( will be at stand still at poles)
5) In northern hemisphere plates moves North ,North East and at Southern hemisphere they move South ,South -west
6) Gondwana was first and last supercontinent, which broke due to violent quakes and eruptions
7) Once plate reach near to poles will never come back to equator
8) Major quakes and eruptions are due to tidal pull acting on molten magma

Why are we so stubborn, not to have a look at other theories?
On seemingly visual signals we have accepted this theory ,like pre historic evidence of rocks or animals from both side of plate boundaries ,which are wide apart now.
However ,think this way...
..yes ,they are separated long ago ,but not due to convection currents but due to violent quakes and eruptions.
Do scientists believe, there were no quakes when there was one super continent and no moving plates?
If there were several supercontinents earlier to Gondwana, where are those plate boundaries now? Are they amalgamated ,or fused in?

5) In northern hemisphere plates moves North ,North East and at Southern hemisphere they move South ,South -west.
In northern or Southern hemisphere plates can not move in opposite direction. What we term as collision of plates is one (nearer to pole) moving slower and one moving faster ( nearer to equator) both in same direction, one pushing from below.
6) Gondwana was first and last supercontinent, which broke due to violent quakes and eruptions
7) Once plate reach near to poles will never come back to equator
8) The 50%+ land mass of which plate is above Equator will move to North ,North-East and vice versa for southward movement
8) Major quakes and eruptions are due to tidal pull acting on molten magma

Amit;
You have it backward; motion is toward equator, not away.
Put a drop of oil on a plate and spin the plate. The oil moves away from center, not toward center.
Same for a sphere.

Few things here
1)You are comparing a two dimensional plate with a globe
2) What you are treating is the centre of a plate as a plot of Earth and circumference as equator ,that is why the whole conflict
3) It try to move from more angular velocity to less angular velocity
Amit;
No, things move due to a force acting on them. In this case it's pulling toward the rim of the plate or the equator of the earth.
Look at a globe. The continents are not at the poles. We have ice there, not major land masses.
Roger
Amit;
No, the force is acting like a pull toward the greater force.
Take a rope. Tie a rock on one end. Grasp the other end and swing it in a circle.
Put a ring on the rope, near your hand. Swing again and watch the ring move away, toward the rope.
Roger
Correction;
"watch the ring move away, toward the rock".
Roger
Roger
What you are talking is a centrifugal force
Ok
Let us look another way
1) Antartica has a huge land mass covered with ice
2) Very little land mass at Equator
3) Plates are moving away from Equator, now
4) speed of Plates near to equator is faster than one near to pole
5) Angular motion is more at equator. A point on equator has to move more distance than point at 50 degree North or South ,during one round of Earth
6) This is more like coriolis motion than centrifugal or even Centripetal for e
Amit;
Yes, centrifugal force toward the equator.
1) Not huge; relatively small
2) False. Look at Africa and South America
3) False
4) True
5) True
6) False

1) Here are the area of land mass in million Square kms
Africa...30
Antartica..13.2
Asia..44.5
Australia...8.1
Europe..9.9
North Amit..24.4
South America..17.8
2) Copare land mass because 5 degree Nort and 5 degree South of equator to land mass between 40 degree north to 50 degree north, you can have clear idea
3) The Nazca plate touching to equator is fastest 10 cm/year where as Euresia plate speed is 2.1 cm/ year
6) pl go through coriolis motion
Correction..
Sr no 2)
Compare land masses between...
Amit;
The odd thing to me is that we don't fly off into space. The earth is moving pretty fast near the equator.
But gravity has us in it's grip so here we stay.
Roger
Amit;
A person standing on the 0 degree latitude of the earth is traveling 1037 miles per hour.
Roger
Roger
And what about one standing right on poles?
So Plates move from high velocity to low velocity
Amit;
Yes, motion is from low to high velocity.
Roger
Amit;
Yes, zero velocity standing on either pole, simply rotating 360 degrees per day.
