the chinese government has bought an entire mountain in peru and plans to ship it back to china – every last ounce. why? it’s one of the largest copper resources in the world and china is desperate for copper which it is planning to use to re-wire its entire infrastructure. this from the bbc…
The Peruvian government is happy with the $3bn (£1.53bn) that Chinalco will invest in the Toromocho mines. The Chinese will be even happier. They have got themselves a bargain. The copper Chinalco extracts from Toromocho will cost something like US$410 (£210) per ton. Today, the price for copper on the London Metal Exchange was $8,255 (£4,220) – 20 times more. Chinalco stands to make a 2,000% profit on its investment.
here’s a short video clip.

this downloadable pdf file takes the reader through contraction theories developed by edward suess and james dana in the 19th century, then into why these were rejected in the early 20th century; how alfred wegener put forward his theory of continental drift and its rejection by many, and finally to the development of plate tectonics. it is a story which shows that the development of scientific theories requires more than just evidence in their favour.

this website has been designed by moorland school in clitheroe, lancashire. it provides some evidence for plate tectonics, comment on alfred wegener’s idea of continental drift, and the earlier contraction theory. excellent animations and information support the topics of sea-floor spreading, subduction, and what convergent and divergent plate boundaries are and where they occur. link here
