    Has anyone done any research on the 'Expanding Earth Theory' and whether 'Plate Tectonics' is a sound theory. From what I have seen the basis for the theory of plate tectonics also fits with that of the expanding earth theory, yet the scientific community just accepts the plate tectonics theory as fact.

    Anyone have any thoughts on this?

    Ok, so this was above people's heads?

    Their is strong scientific evidence that the Earth is growing/expanding. The land masses of the earth were in the past intact, if you look at a world map it is obvious that certain continents were once attached.

    This was discovered and the scientific view was that if the Atlantic Rift was growing then the Pacific Ocean was subsiding. However, this only works if the assumption that the Earth remains the same size.

    Oceanic Lithosphere (dating of the sea bed) also shows that the pacific sea basin is also growing. Now this means is plain English the sea beds are enlarging and the land masses are remaining the same size. In simple terms the Earth is growing/expanding at an alarming rate.

    Did anyone ever explain this to you at school?

    Now ask yourself what else haven't I been told?

    so is this why sea levels are rising if so it makes sense

    I've often wondered if the earth is getting bigger, but my reasoning is very silly. When people do archaeological digs, they go down various layers spanning time. It made me think that people, animals and plants are constantly producing extra 'stuff', for want of a better word. The population is getting bigger, that's more bodies for starters. I'll admit, it's a pretty daft thought...! But then I thought that maybe all this 'stuff' just gets compressed down over millions of years and eventually turns into oil. I have a very simple mind that thinks strange things, sometimes.

    The story I noticed yesterday was that the Universe was getting bigger. I hadn't heard the Earth theory at all.

    tiger lily that is what I have been thinking, when you walk through a wood you see the layers of leaves from last year and the year before they break down and more soil is produced simple way of looking at things or good it be like one of the moons that is circling a planet forget which one gets stretched by gravity from the planet as it orbits, of course I could be shot down but maybe some of the members with a more scientific mind could enlighten me more

    Plate Tectonics is a theory, but I would think it is pretty universally accepted. To the OP, what is wrong with accepting it as fact?

    I'm not sure why people would think the earth is "expanding". It is a hypothesis that is largely discounted by measurements of the Earth.

    As the crust moves, plates either diverge or converge. This is easily researched. Basically, the crust is "recycled".

    I think you'd find sea levels fall if this were the case, CR. Sea levels rise because of the melting ice caps - the one over the northern half of Europe used to be some mile or so thick - there have been massive rises in the last 20.000 years and some ancient civilisational buildings can be located on what were the original coastal plains, now under water - see Graham Hancock's Underworld, Flooded Kingdoms of the Ice Age.

    As for the tectonic plate theory - that is relatively new. It seems to answer many questions about movement of the land masses over the surface of the planet. I think you'll find that while some plates are moving apart there are others that are folding under another as the plates collide or like where India is moving northwards, this is pushing up the Himalayas - which is why sea fossils can be found up there! And why the Californian fault is unstable.

    If, as you posit Hertford, Earth is expanding - where does the extra matter needed to do this come from? As far as I am aware there isn't enough fallout from outer space landing on this planet. You might suggest the core is expanding due to gas formation, but this would blow-out as increased volcanic activity and this does not seem to have increased, but is thought to be decreasing as far as I am aware.

    And yes, while we are able to uncover archeological information by digging down in some areas, there are other parts where errosion has wiped the slate clean, so to speak. There is continual movement of particulate matter across the globe due to the forces of nature - wind, and water particularly, and man tends to build on former sites of occupation and as each new build is constructed, in the past it has been over the last layer.

    These are my thoughts anyway.

    hi caroline n I hoped someone would put me right lol

    I think this is the sort of topic best discussed over several glasses on wine

    I would also add that gravity is inclined to hold things together, so the planet is unlikely to start expanding at any time unless something upsets the gravity field when we should all be very aware of it.

    I think this theory of expanding Earth is 'dead in the water' - so to speak. On the other hand the universe does seem to be expanding - and whether it is still from the last Big Bang - that's a different matter!

    If the Earth was getting bigger, the relativistic corrections made every picosecond in the software operating the GPS system would detect it instantly, as their orbits would be unstable. These things make incredibly precise measurements of position all the time.

    There is no evidence to support an expanding Earth model, but there is an enormous amount to support Plate Tectonics from geology, palaeontology, geophysics, mineral and oil mining etc.

    Plate tectonics, like evolution is a proven fact. Earth can only expand and contract within the confines of its size, so for every expansion there has to be contraction. This happens when newer rocks extrude from volcanoes and older rocks are 'subducted' at destructive plate margins. This is why whenever there is a major earthquake, a volcanic eruption follows, and vice versa.

    Next time you hear of an earthquake/volcanic eruption having happened, wait a little while to hear about the 'other half' of the process i.e. the volcanic eruption/earthquake.

    Love,
    Patsy.

    Hi Tigerlilly,

    Oil and gas are produced from rotting vegetation, not from any 'expanding Earth' notions.As swampy conditions change, all the rotting vegetation is gradually compressed into peat, which will eventually become coal/oil/gas if left for sufficient time.

    The Universe is certainly expanding, but as Sam says, if the Earth was expanding too, it would be very unstable.

    Patsy.

    Unless, of course, everything is expanding relatively, in which case we wouldn't even know about it. :D

    While some earthquakes "cause" eruptions and vice versa, this is not inevitable.

    Hi Crowan,

    Would you like to expand on that?

    Ta,

    Conservative plate boundaries are associated with earthquakes, but not with volcanoes.

    You are perfectly correct, Crowan: conservative plate boundaries are (mostly) connected with earthquakes. Most rocks are created from them...but....the rocks at destructive plate margins ore older and they have to subduct under the continental crusts, and it is this that causes volcanic eruptions. hence 'eruption follows earthquake.'

    By the way, going back to the original post, the scientific community doesn't accept a theory as "fact", it accepts a theory as a theory. That is, it makes sense when all the known facts are taken into consideration. Therefore, the probability is that it is correct.

    Plate tectonics, like evolution, is a theory consistent not only with everything we knew at the time but also consistent with everything we have found out since.
