(kən-vûr'jənt) A tectonic boundary where two plates are moving toward each other. If the two plates are of equal density, they usually push up against each other, forming a mountain chain. If they are of unequal density, one plate usually sinks beneath the other in a subduction zone.]]> 2018-03-29 15:44:07 UTC https://padlet.com/303395/dqtfw0rnmey8/wish/247301105 303395 https://padlet.com/303395/dqtfw0rnmey8/wish/247301390 divergent plate boundary in Science. divergent plate boundary.

At transform boundaries lithosphere is neither created nor destroyed. Many transform boundaries are found on the sea floor, where they connect segments of diverging mid-ocean ridges.

Typically, faults are associated with, or form, the boundaries between Earth's tectonic plates. In an active fault, the pieces of the Earth's crust along a fault move over time. The moving rocks can cause earthquakes]]> 2018-03-29 15:46:18 UTC https://padlet.com/303395/dqtfw0rnmey8/wish/247301936 303395 https://padlet.com/303395/dqtfw0rnmey8/wish/247302310 the upper layer of the earth's mantle, below the lithosphere, in which there is relatively low resistance to plastic flow and convection is thought to occur.]]> 2018-03-29 15:47:18 UTC https://padlet.com/303395/dqtfw0rnmey8/wish/247302310
