Interesting, but it also has flaws in its logic.
Such as: If the world is getting bigger, where is this new matter coming from?
I haven't heard of this before, but there is some evidence to find some support but that question above is my major reason for doubting it.
Expansion doesn't necessarily mean more mass.
Build up of gasses or magma slowly expanding.

If the earth was getting larger, its surface would be getting further and further away from the earths core over time, and the core is responsible for our planets magnetic field. Thus if this really happened, there would be evidence of this in ferous rock samples all across the world.
But there isnt.
This video is gay.
There's something like 1500 land volcanoes that have been or are active now (don't quote me..too lazy to confirm it). This is not including many, many more in the ocean.
>And if I recall correct, the earths density is thicker the further into the core you get, which could explain why it gets bigger without adding mass.
It does indeed get more dense as you get closer to the core. But I'm not sure what you mean by getting bigger without adding mass.
The current mass of the earth is ~5.9736×1024 kg. People did not pull this figure out of their asses, there are ways to measure the mass of the earth. One is to measure the acceleration of a dropped object to the surface (in other words, the strength of our gravity, which is directly related to mass).
Um, assuming that were correct, I don't get your point. You're saying that debris falling to the earth's surface is adding to it's mass (and therefore, it's size)?
"No subduction happens!"
Ok, where does all that matter dissapearing beneath the trenches go then? Does the theory also have an argument in favor of the existance of a 'seafloor fairy?'
The Mid-Atlantic Ridge is an example of a Divergent, or Constructive, plate boundary. Here, magma rises to the surface and cools; the plates are moving away from each other.
The opposite of this is a Convergent, or Destructive, plate boundary. Here, the denser plate subducts underneath the lighter plate. An example is the Nazca trench on the Pacific Coast along Chile. It results in the creation of volcanoes as the dense oceanic plate melts and rises as magma.
Yes, they both create volcanoes. Destructive margins generally create explosive volcanoes, while Constructive margins create volcanoes which are pretty much continuously erupting in a non-explosive manner.If I remember correctly, both divergent and convergent boundaries create volcanoes, just not transform fault boundaries (which cause earthquakes). Just a tiny addition
Erm, did you not read my previous post? Subduction occurs at destructive plate margins and creates ocean trenches. Subduction is sort of like the opposite end of the cycle where magma erupts as lava onto the surface, then goes back into the mantle at destructive margins, and that's subduction.Why? The volcanoes keep ejecting magma and lava into this hellhole we call home and the Earth's crust is growing. Soon all or most of the mantle will be gone and/or compressed or cooled.
Now, this isn't subduction. The Earth is getting deeper, but also heightening. It's spreading, because mantle is VERY DENSE as stated in the video. I don't call soil or aluminum very DENSE, do you? So it's also getting bigger physically, and/or spreading out and getting DEEPER
I lay claim to that title over you, actually. A grades all round in geological sciences hereI AM THE GENIUS OF GEOLOGICAL SCIENCE! PHEAR ME! No, not really, but close
