tectonic

Continental collision is a phenomenon of the plate tectonics of Earth that occurs at convergent boundaries. Continental collision is a variation on the fundamental process of subduction, whereby the subduction zone is destroyed, mountains produced, and two continents sutured together. Continental collision is known only from this planet and is an interesting example of how our different crusts, oceanic and continental, behave during subduction. (www.wikipedia.org)

Broadcast (1998) What drives the tectonic plates as they glide over the Earth's surface? Searching for an answer scientists have probed our planet to its core. In this realm of unimaginably high temperatures and pressures matter takes on new forms and solid rock can behave like a fluid. As vast masses of rock flow slowly within the Earth, so the surface moves and changes. Gigantic plumes of hot material can well up from the depths, triggering huge volcanic eruptions and causing the crust to bulge and break. The result may be the splitting of a continent.
