Physics with trees, Period 1, 24 Sep '08

The classroom opened up several feet away from the top of a low cliff. A sandy trail wove down to the shore where waves broke against its base. The sounds filtered up, and Mohinder - jacket pulled up around his neck against the wind - spoke up and over the background noise. "We're standing on a narrow crust of earth over a red-hot mantle," he said, exercising a little artistic license. "Layers upon layers built up and shifting, crashing together and tearing apart." A pause. "On a scale of millions of years, at least."

Mohinder covered plate tectonics quickly, before moving on to rock formation. "Two of the three rock types are sedimentary - that is chalks, shale and sandstone," he described, pointing out samples from the minerals collected at his feet. "While a metamorphic rock - slate or marble - has changed under heat and pressure from its original identity."

Having given out identifying handouts, Mohinder stepped back, saying, "You should be able to find many types of these minerals in the surrounding area." The Danger Shop was useful like that. "Take a look, and see what minerals you can identify."
