quote:A quick one, from someone who doesn't know much........If the earth isn't growing, why are most fossils (including fossil fuels) buried? any time you look at a deep hole/land mass movement, its in layers, suggesting that it has been built up. if the earth was staying the same size, wouldn't every thing just be on the surface?

quote:Originally posted by BassThe surface of the Earth is dynamic due to the motion of the plates. Because of plate tectonics, we have a rock cycle- ocean basins form, collect sediments (including fossils and fossil fuels), get uplifted, squeezed into mountains, erode, dump sediments into new ocean basins...A static surface, whether growing or not, would result in "Waterworld"- no land masses, no sediments (other than organic material) and we'd all have to grow gills in order to survive.
quote:Originally posted by daveshortsMost volcanism on the earth is related to plate tectonics, if you have a look at it's distribution it is all along the edges of the plates, there is some that is not, Hawaii for example, but that is definitely in the minority. Mars does have highlands, but it also doesn't have water, so errosion is far less active, hence mountains are fossilized for far longer.If the world was just getting bigger with no plate tectonics the rocks may be in layers, but you would never see them as you wouldn't get uplift so the layers would allways be under your feet.
quote:Originally posted by another_someoneI am not questioning that many of the land features we see would be absent, only that this would not make the world featureless.
quote:The Moon is pulling away from the Earth because the force of gravity exerted by the Earth is slowly diminshing. This is due the slowing of the earth's rotation. All in all, it's a very slow process, but when the earth was spinning faster, the Moon was much closer.
quote:Originally posted by ukmickyYes the earth core is cooling and its mainly only the size of the earth and its position in relation to the sun which has prevented it from going the way of marsMichael HAPPY NEW YEAR
quote:New information about what is inside Mars shows the Red Planet has a molten liquid-iron core, confirming the interior of the planet has some similarity to Earth and Venus. Researchers at NASA's Jet Propulsion Laboratory (JPL), Pasadena, Calif., analyzing three years of radio tracking data from the Mars Global Surveyor spacecraft, concluded Mars has not cooled to a completely solid iron core; rather its interior is made up of either a completely liquid iron core or a liquid outer core with a solid inner core. Their results are published in the March 7, 2003, online issue of the journal Science. "Earth has an outer liquid-iron core and solid inner core. This may be the case for Mars as well," said Dr. Charles Yoder, a planetary scientist at JPL and lead author on the paper. "Mars is influenced by the gravitational pull of the sun. This causes a solid body tide with a bulge toward and away from the sun (similar in concept to the tides on Earth). However, for Mars this bulge is much smaller, less than one centimeter. By measuring this bulge in the Mars gravity field we can determine how flexible Mars is. The size of the measured tide is large enough to indicate the core of Mars can not be solid iron but must be at least partially liquid," he explained. The team used Doppler tracking of a radio signal emitted by the Global Surveyor spacecraft to determine the precise orbit of the spacecraft around Mars. "The tidal bulge is a very small but detectable force on the spacecraft. It causes a drift in the tilt of the spacecraft's orbit around Mars of one-thousandth of a degree over a month," said Dr. Alex Konopliv, a planetary scientist at JPL and co-author on the paper. The researchers combined information from Mars Pathfinder on the Mars precession with the Global Surveyor tidal detection to draw conclusions about the Mars core, according to Dr. Bill Folkner, another co-author on the paper at JPL. The precession is the slow motion of the spin-pole of Mars as it moves along a cone in space (similar to a spinning top). For Mars it takes 170,000 years to complete one revolution. The precession rate indicates how much the mass of Mars is concentrated toward the center. A faster precession rate indicates a larger dense core compared to a slower precession rate. In addition to detection of a liquid core for Mars, the results indicate the size of the core is about one-half the size of the planet, as is the case for Earth and Venus, and the core has a significant fraction of a lighter element such as sulfur.
quote:Originally posted by Andrew K FletcherIf the Earth's core is cooling, how come it ain't cooled yet?? More to the point, how come the core's molten constituents are spued out of volcanoes and hot water bubbles out of the rocks?You are off your frigging nut if you believe this garbage. Come on, umpteen billion billion billion billion years old and it aint half hot mum.
quote:The planet's internal heat was originally generated during its accretion, due to gravitational binding energy, and since then additional heat has continued to be generated by the radioactive decay of elements such as uranium, thorium, and potassium. The heat flow from the interior to the surface is only 1/20,000 as great as the energy received from the Sun.
