Interesting Things I Learned in Nat Sci II - Part 1 / Growing Earth Theory

20 April, 2007 (17:45) | General, School | By: Mi

Hi. I’m going to write down the things I just learned that I thought were interesting to know. I guess I didn’t pay much attention in High School in case these were mentioned already. If these are common knowledge…. well.. I must be stupid. That just means there’s always something new to know. Take note that some of these are from theories like the Plate Tectonics, Sea-floor spreading, Continental Drift theories.

  • India is believed to be formerly connected to Australia and Africa I think and they used to be somewhere near the South Pole.
  • India was formerly not a part of Asia. >__> The Himalayas were formed when it moved against the Eurasian Continent.
  • The Philippines is probably not really a part of Asia.
  • The Philippines has its own tectonic plate–The Philippine Sea Plate.
  • Japan is kind of located where 3 plates meet–thus the strong and frequent earthquakes.
  • Diamonds are NOT forever. They will someday … umm.. dunno. disintegrate or something. They are made of carbon and formed under extreme pressure and heat. Being on the earth’s surface makes it removed from its nature. >_> Though this would happen not within your lifetime. Maybe 10000 years or more?
  • There are volcanoes under the sea.

I think the Earth is expanding. I don’t know if there are already theories about this, but I really believe that the movements of the plates, spreading of the sea-floor, and so on, is caused by the earth growing a little. I wonder if the measurement of the earth’s circumferences (polar and equatorial) have always been the same throughout the years. Have they recently remeasured? lol. I don’t know exactly. But the earth growing is a good theory. Because of the differences of composition of the earth’s crust, their movements or “stretching” is also different. Imagine a man with a pot-belly. The shirt isn’t always perfectly stretched over it. Sometimes it bunches upwards. Maa… I don’t know. I mean, aside from the Plate Tectonics and Sea-floor spreading theories, the Growing Earth Theory would kind of be like behind all of these. The magma underneath also grows. It gets heated and heated and the particles move faster and farther apart. They say subduction isn’t explained in this theory, but like I’ve said above, probably the differences in composition has made some plates stay put, or move slower than other plates.

From the plate tectonics and sea-floor spreading theories, I still couldn’t imagine how India has come to where it is now. I mean, if just for those theories alone. But if I think of the growing earth theory, I could imagine. ~___~

THE EARTH IS GROWING!!!
