Thread: a new twist- Earth is growing

Is it just my slipping into a time warp.. or has a load of posts disappeared, and you have said that before in different words Howie..

Or have I just fallen through the DV fabric of spacetime..

I split the topic, as a few have requested.
I think the missing few are in philosophy sec?
I thought there was nothing of any substance, let me recheck!!!!!!!!!

[EDIT]NO, I think the two I did not add to the split were my response, which you had noted, and then another request for it to be moved.
I hope that was all.

the one in philosophy redirects here, and I can't find the rest..

theres like 7 AWOL posts.

Not that it actually matters, to be honest.

You may as well delete the thread altogether now since the first page or so, including the initial creators post, are missing...

Okay so I'm going to try to participate in this thread despite having missed out on all of the first page.

From what I've gathered, it seems that people are discussing whether or not the Earth may be growing, and other possible causes of moving plates.

The plate issue can be explained many ways other than through convection currents. For instance, if the tectonic plates were riding on a molten layer (which they are) and the planet was spinning (which it is), the plates would be subjected to a coriolis force. If the plates were of varying sizes, and therefore differing masses (and this is the case) they would have different momentums which would allow them to move at different speeds and collide with each other periodically. Imagine "spinna's" on some fat 22's that have several parts of various sizes capable of rotating independently of each other. Each part would spin at a different speed and so their rotations would conflict with one another.

The Administrators are looking to see if any of the data is retrievable.

My best guess, when I split the topic everything went dandy. Then I was to delete the last two posts > A request to move the thread into extended discussion and then my reply to that post. This may have been where the mistake took place.

Maybe it is buried somewhere.
I really apologize for this folks.
If the original author or anyone could retain that original download on the concept of the earth growing, would be very much appreciated.
I will be looking in the meantime for the original.

Sorry guys

Saturn's moon Titan shows signs of expansion. It's covered with octahedral craters that suggest it is in fact growing much like a crystal would.

It's a very freaky moon full of strange anomaliles, especially the large "seam" that runs through the middle of it.

Of course the other theory is that is is an artificial "death star"

Could be a titan; you know, literally.

From what I have read of Titan, is that they do not now all that much. But what they do or think they know, is not a good comparison to earth.

sorry to reserect this post but its really interesting and I thought I would chip in to give my ideas.

This expanding earth theory is completely false.

Someone mentioned about earths mantle being liquid which is incorrect, it is in fact know as "semi-plastic" which means that its essentially solid but under high temperatures and pressures and given time it flows slowly. The only luquid part of the earth is the outer core supported by S-Wave data (a type of earthquake which does not pass through liquid)

So the spinning earth has very little effect on the crust, not like it does upon the outer core (which is part of the reason for the magnetic field)

Xei mentioned his geography teacher said that there is no convection which is also false.

The entire plate tectonic theory supports that: -


Basic Plate Tectonic theory

Convection is caused by radio active decay in the core heating the surrounding material, heat then breaks from the core rising through the mantle (similar to what you see in Lava Lamps) until it hits a cooler layer like the crust. (its much more complex then that but I will keep it simple)

Constructive margins (eg the mid Atlantic ridge) - caused by the pulling effect where the heat source hits a cooler region and spreads below the crust causing rifting.

This is supported by dating techniques which show that the rocks at the center of the rift are young and get progressively older the further you travel. and is also supported by research into magnetism which I wont go into as it will take to long to explain but if anyone requests it I will explain.

Subduction zones - caused by the spreading of the mantle material and the subsequent descent of the now cooled material back into earths interior

this is supported by huge amounts of earthquake data, seismic tomography (similar to the MRI machine which forms slices so you can view what is inside) which actually shows the ocean plate sinking (with the cooler material of the mantle) etc etc.

It is also worth noting that the oceanic plate is of different material to the continental plates which is why it is always the oceanic plate that sinks because of a denser and less varied mineralogy.

Now when the subduction occurs it forms zones were one plate is crumpled thus forming mountains and allowing for erosion which changes the composition of the crust making it much lighter and forming the Continental crust, this is why in places like the Himalayas (were 2 continental plates collide) there is no subduction because they are to light to sink.

Hotspots - are places where a convection cell is not strong enough to form a rift but still produces heat sufficient to produce volcanoes. examples of this are Hawaii and Iceland.

The above things are by no means all of the evidence for plate tectonics but I cant be arsed to go into further detail lol

Proof that the Expanding earth therory is wrong

Now the reason why the earth is not expanding is simple. If it was expanding there would be no mountains because all plates would be surrounded by constructive margins so there would be no "crumple zones" and there fore no continental crust at all.

Also because there would be no mountains and therefore no erosion all the planet would be of the same mineralogy (that formed on the ocean floor) which frankly it is not.

Case closed as there is no evidence
