They only give you a small part of a big story. For example, they say that the Himalayas should have eroded over time, not still be so high. THAT'S BECAUSE THE MOUNTAINS ARE STILL GROWING! The Indian and Asian? plates are pushing together forcing the mountains up. That counteracts the erosion. Doh! The say the coast of the US should have eroded much more than they have. CONTINENTAL SHIFT - PLATE TECHTONICS! North America hasn't been in the same place for 3.5 billion years! Doh! They hope their viewers are clueless about these subjects so will be easy to catch. You'll enjoy this if you want to believe the earth is much younger than scientists say and are afraid to talk to scientists in case the facts upset your imaginary world.
