Living on the plate margins

What be dwelling margins? Plate margins are the edges of the plates, where all the power of disposition is released in primer coatquakes and volcanoes. There are three main characters of plate margins: - Spreading Boundaries There are devil tokens of spread head boundary Ridges, where bare-assed rock is formed, push the plates apart, and Rift, where the plates pull apart, and the earth between them sinks. On the ocean floor the plates are spreading. on the whole along the mid ocean ridge, volcanic action at law is pouring new lava out onto the seabed. As it hardens, it becomes new rock, plotmeal pushing the glow, on either side of it away. Another eccentric of spreading boundary is the African Rift Valley. As the 2 plates are moving apart, the earth between them is becoming stretched. As it stretches it sinks, because it is thinner. It is a little bit like taking a humankind of gum, and stretching it out. The pieces in your fingers stay thick, but the piece in t he middle gets thinner and thinner, as it is stretched. intersection Boundaries Converging (coming together) Boundaries, are where two plates are banging into each other. What happens when they clash depends on the type of plate they are. In a subduction regularize one plate is world pushed beneath the other.

It happens when a brightness level plate hits a thick plate. The lighter plate is pushed down the stairs the heavier one. This often happens where continents meet the ocean. As the lighter ocean crust is forced downwards, it takes urine with it. The water causes the rock to melt at reject temperatures than normal. The pressure inside(a) the ear! th is much greater than at the surface, it increases the deeper you go. The new molten rock tends to rise to the area of lower pressure, sometimes forming...
