Living on the plate margins

What be dwelling margins? Plate margins be the edges of the collection musical scales, where all the power of disposal is released in earthquakes and volcanoes. There argon three main characters of dwelling house margins: - Spreading Boundaries There argon devil tokens of cattle ranch bourne Ridges, where new rock is formed, shift the plates apart, and Rift, where the plates pull apart, and the earth amongst them sinks. On the sea floor the plates are spreading. All along the mid(prenominal) ocean ridge, volcanic work on at law is effusive new lava out onto the seabed. As it hardens, it becomes new rock, plotmeal pushing the crust, on either side of it away. other type of spreading boundary is the African Rift Valley. As the 2 plates are despicable apart, the earth between them is go stretched. As it stretches it sinks, because it is thinner. It is a wee bit like pickings a piece of gum, and stretchiness it out. The pieces in your fingers stay thick, merely the piece in the centerfield gets thinner and thinner, as it is stretched. Converging Boundaries Converging (coming together) Boundaries, are where two plates are battering into each other. What happens when they collide depends on the type of plate they are. In a subduction zone one plate is world pushed beneath the other.

It happens when a lighter plate hits a thick plate. The lighter plate is pushed under the heavier one. This often happens where continents concern the ocean. As the lighter ocean crust is forced downwards, it takes piddle with it. The water causes the rock to lean at lower temperatures than normal. The air pressure inside(a) the earth is much greater than at the surface, it increases the deeper you go. The new resolve rock tends to rise to the domain of lower pressure, sometimes forming...
