Palm trees growing on or near the south pole,etcChris, if the Earth were surrounded by a sphere of ice, wouldn't it make sense that this would block some of the sunlight, therefore making the Earth colder? Unless there was some mechinism for re-directing heat, the poles would still be cold, because they receive less energy from the Sun. The poles are covered with ice because they are cold; they're not cold because they are covered with ice.And a whole messa little comits (I can't remember part of it here).Are attractid to the magnetic poles of the earth.There is no evidence that comets contain any signicant amounts of metal, so it is unlikely that a magnetic field would affect their path. Even if the comets were metal, the Earth's magnetic fields are weak enough that a comet moving slow enough to be re-routed by the magnetic fields would not be moving fast enough to cause much damage."Hey what's goin on" as -200 degree "snow" is falling on them.Actually, they would be more likely to get scalded. As the water fell, it would be giving up a great deal of potential energy, which would be converted to heat. Absent a layer of cold air, it is unlikely that it would still consist of ice.The pressure of the water combined with the smaking and freezing cause massive shifts as to solid ground.Mountains and vallys are formed in a short time.If all the mountains were formed at the same time, why are the Appalacian mountains so much more eroded than the Sierra Madre mountains? You can't claim that it is because there is more rain in the east; even the Alps are much less eroded than the Appalacians. Also the earth is "all shook up" hmm,hmm,oh yea yea,and re settles.Or should I say restratifys.If the earth re-stratifies, we would expect fossil remains to be evenly distributed through the layers. But this is not what we find; instead, only very simple life forms are found on the lowest layers; as you move up in layers, you start to find more complicated life forms. It is only when you get to the very uppermost layers that you start to find evidence of modern animals.Also, you would expect the layer to be rather homogenious. This is not what we find. Instead, the layers are sometimes of rather different materials. In addition, sometimes layers are not parallel, reflecting changes in the orientation of some of the rocks in early times (eg, an upheaval in the Earth's crust lifts up an area, tilting it. Over time, the vally fills in with sediment. The place where the new sediment meets the old layers forms a discontinuity, where the layers are at angles.)David
