Hi Ng after my little essay about plate tectonics stayed unnoticed somewhere at the end of another thread, I decided to open a new thread about this subject and paste my arguments against plate tectonics into it. So, since Tom Roberts went away without replying, I repeat this little essay about Plate Tectonics vs Growing Earth here: Landmasses do not rise. This hypothesis 'rising landmass' is a completely silly idea, since land is actually the crust of planet Earth. And the crust does not lift and float away. So, if landmasses rise, than because something (the land is resting upon) if pushing that piece of Earth' crust up. Plate tectonic assumes, that other plates perform this stunt, because they 'dive' under the lifted plates and therefore push it up. This is called 'subduction'. But the mechanism does not work. One reason: the Earth' mantle is not liquid. So the 'diving' plate has actually a hard time in trying to dive into a solid, since not only is the mantle not liquid, it is also of higher density and of higher pressure than the material, what tries to enter. And these plates have actually no good reason to try, since there ain't no force, that is pushing. Plate tectonics assumes, these forces are applied by 'convection currents'. But that can't be the case, because the mantle is not liquid. And without being molten, the material will not float around and therefore would not apply a force to the crust. Another serious problem, plate tectonics failed to explain, is the impossibility of a piece of the crust to move at all. To illustrate the problem I suggest the following experiment: take a water-melon and draw all the plate boundaries of Earth plates on it (with a felt pen). Then take a knife and make (shallow) cuts along these lines through the melon's 'crust'. Now move the 'plates'. You'll find: they can't be moved. Reason: they 'stick' to the ground and there are other 'plates' in the way. In real and on Earth' scale we have gravity, which tries to pull these plates to the centre. Since the Earth is spherical, the borders of these plates have conical angle, which are pressed against the other plates by gravity. And since such plates are very large, the borders are thousands of kilometres long. Since plates could be about 40 kilometres thick, we have an area of several 40,000 km², upon which tremendous pressure rests. Now the force that tries to slide one piece along another has to overcome friction and friction is dependent of area, pressure and a certain factor for the material. There is also the factor of form, which is hindering movement. And there are also plate in the way, since the Earth is - of course- totally covered with crust. Since usually friction is calculated in mm² or possibly m², you have difficulty to imagine forces high enough do overcome friction over one km². But we have 100000+ km² and VERY high pressure. In short: subduction does not work. But plate tectonic without subduction IS 'Growing Earth'. Growing Earth is also an alternative explanation to geological features, which are commonly ascribed to an Ice Age. So: no ice age with GE! The sand explained by the glaciers is assumed to have been caused by former ocean-floors, where now is land, covered with sand. This is an alternative explanation and would make ice ages obsolete. There might have been one or more ice ages, nevertheless, but the sand and pebbles are assumed to have been created and transported by liquid water, not by ice. Land does not rise! Especially not rising are high mountains like the Himalayas. G.E. has a different explanation for mountains: that they have been created under water, as 'sea-mounts'. The creation of islands as consequence of volcanic activity is different in water than on land. Volcanoes on land create conic shapes, while volcanoes in water create much steeper angles, since the water cools much faster than air. If the sea-levels fall, the former islands sit on the land as a mountain (covered with oceanic fossils). Globally sea-levels fall on average on a rate of of about 4m per millennium. This rate is changing and is actually accelerating. But currently we seem to have this rate. It is simply derived from the Lake Trajan near Rome. This is now 8m higher than the Mediterranean Sea and roughly 2000 years old. Since we have no reason to assume, that the Romans didn't know, where the mean level of the Mediterranean Sea was, we can safely assume it was exactly where the surface of that lake is now. The rate of 4m/1000 years gives a precise 'clock' for geological/historical events. E.g. the ancient city of Troy was once a harbour, which controlled the entrance to the Dardanelles. Now the former port sits on a hill, 30m above the Mediterranean Sea. This gives an age of certain structures of about 7500 years. The source of sand in the ocean is not only the shores. The coast is roughly a line. But you must think about the ocean in three dimensions. The water would erode any material within reach. There are also rivers, which bring sediments. Then the stuff sinks to the ground. Also rocks roll in currents and get grind round. So we get sand and boulders, that cover the ground. Now imagine the water goes away and compare this with typical landscapes. After you think about it for a while you will find, that many landscapes could be interpreted that way: If sea-levels fall, the former ocean floor turns into marshes. Then comes grass and trees, that could grow on former organic sediments. But than the process goes on and the fruitful vegetation vanishes, after the are dried out. Then we get the sand back and see it without cover. (This is mainly a natural process and what causes deserts). Internal seas, that have been cut off, turn into lakes and once the lakes dry out, the area turns into a salt pan in the mountains. Typical example: Utah or Atacama desert or Goby desert. The Sahara could be explained as former ocean, too, where we find former islands, that are now hills on a flat sandy area. Also important: air erosion does not create flat landscapes. All sorts of planes require liquid water, what had levelled out differences in hight by grinding off things. Air erodes, too, but WAY less than water. So mountains could stand for eaons, while coastlines change relatively fast. The typical form created by water is rounded. We find pebbles and boulders, but also rounded islands. Such rounded forms of rock could hardly be explained without some sort of ocean. And now we find such formations in high regions, like in mountains. Similar formations are so common, that we hardly recognise them. But if you ask yourself, how e.g.horizontal line manage to occur in hill-sides, than former shorelines would be an explanation. Other hints for former water are sediment rocks, like sandstone or chalk. Sediments required a body of water above, where stuff sank to the ground in former times. Mountains could be interpreted as former sea-mounts, like e.g. the Canary Island of the Hawaii chain of islands. Typical is the slightly curved form of a chain of island, we find in similar fashion in the Alps or the Himalayas. Now let's compare this with what plate tectonics assumes as explanation for the same observation: Plate tectonics assumes, the mountains are folded up by the pressure of the approaching plate. That is in the case of the Alps the African plate. But that is flat wrong, since between Europe and Africa is the Mediterranean Sea, where we find volcanoes (like e.g. Stromboli). And such volcanoes are indication of spreading. At least the pressure applied by the African plate could not be too significant, since we find Italy in direction of this pressure. And Italy does not look like being folded upwards. We also have the Adriatic Sea as kind of rift in North->South direction. And that does not fit to an approach of the African plate. Then we find marine fossils on the Alps, like shells and fish-bones. This would be another hint for former water. PT assumes, these fossils had been lifted up together with the rock, by the pressure, which folded the rocks upwards, that Alps are made of. But crystalline rock is difficult to fold. Actually it cannot be folded at all, not even in geologic times, since a massive block of stone will not bent, even under tremendous pressure. If pressure exceeds the strength of the rock, it will break, since that is the behaviour of almost all crystals. And the Alps don't look like broken to pieces. Growing Earth assumes - in contrast - a feasible way of creation of mountains, but created under water. The water is the key to creation of mountains, since it cools lava much faster than air. So volcanoes in the oceans rise fast to the surface. Then the plates move a little bit and the next volcano rises above the same hotspot and builds another island. This gives a typical curved chain, we find in many mountains. >> Land does not rise!

And there are literally zillions of GPS measurements > showing continental drift. > How long does GPS exist? Maybe twenty years, possibly a little more. But geological timescale has a grid of millennia or million years. You simply don't measure changes of the Earth itself in a year, because that is equivalent to a milliseconds in human life. And you would not measure hair growth in milliseconds, but e.g. in mm per month. So we need a million year as typical grid in geology and not a year. And since the Earth is about 4,5 billion years old , we get 4500 data-points, if we 'measure' once a million years. And that would actually be enough. But shorter intervals would deliver a finer grain, so eventually a millennium is also acceptable. The year is way too short for typical changes of the Earth, hence cannot be seen at such a pace. TH
