      This documentary attempts to explain the difference and the correlation between plate tectonics vs. expanding earth. The latter apparently challenges the theories of plate tectonics.

      Simply put, plate tectonics supports the theory related to continental drift, which was formed in the early 20th century. This theory states the earth’s lithosphere, which is found way below the sea, is broken up in to different plates, which makes it pssible for continents to converge, collide or transform. We experience earthquake and volcanic activities as a result of these plates moving and crossing boundaries.

      The expanding earth theory, on the other hand, holds that the volume of the earth is gradually increasing, and this is the reason why it’s causing all those movements and disturbances.

      Betwent these two theories, scientists seem to have accepted plate tectonics more. But new evidences from those who continue to study the expanding earth theory seem to have once again spark the science community in a debate.

      This documentary presents the two arguments and theories to help better understand the subject.

      hey the first video: "Expanding earth theory"
      was removed by the USER !!! Please update it ASAP!!!! thanx u rock !

      The (nice) person organizing/maintaining this site is in his exams period till the 21st, please be patient.

      You can read it in the little red text up the page, but it's easily overlooked (Q^Q).

      I thought the earths core was kept molten by the push pull action of its rotational passage around the sun ?

      Come on, the Earth is a rock… maybe you can tell me that a rock somehow magically grows but I’ve held rocks in my hand and they don’t.
      Plate techtonics remains the only one of these two theories that is possible.

      The Earths core is molten because A) Pressure : The deeper you go the more pressure there is, the more pressure there is the higher the temperature (although the depth/pressure ratio is not entirely consistent) B) Radioactive decay : The elements inside the Earth are constantly emitting particles (Beta particles I believe) this emission generates energy/heat, although there is a finite amount of particles there is enough in the Earth to last about 10 billion years.

      learned somewhere about the expanding earth theory that earth was possibly the core of a gas planet. With the gas stripped off by solar wind or something, the solid core was allowed to decompress. The more i ponder the more it makes sense.
