It's a good material for seismology. If they perfect this, they'd be able to predict the coming of an earthquake and tsunami. It would really be a great help.

Cool upload!

The recent increase in earthquake incidence combined with the apparent decrease in geomagnetic strength indicates something very important happening in the coming years. we could have a few more years to observe the effects but I'll give it one more year.

I've made my own expansion models and I've also seen animations. Expansion is real, but I've observed a few additional things. There are are also phases of contraction and compression. This is what is perceived as subduction using tectonic models. I've also modeled to less than 40% radius. The 'plates' (continents, in fact) were lying on top of each other in some areas. They slid off each other like layers of an onion. I've also observed an oscillation energy creating many other mountain ranges.

You're freaking funny "geoscience professor".

Subduction does not occur??
It could hardly be avoided in temperature convections in a molten liquid mantle!
You don't have much of a grasp of geology.

the earth is growing always has been,all the landmass fits together if you shrink the globe and take away the water,heat expanse earth and water condenses in our atmosphere

Subduction does not occur. There is no mechanism that could force a plate move laterally across the planet surface. They aren't masses floating on water that can be blown by the wind, and no other potential force for causing subduction is ever suggested. Granite and lower levels basalt would both be subducted, yet only basalt is appears where plates spread. What happened to the granite? Nothing. There is no subduction. The planet is growing and continents are seperating. Mountains form by other
