If the two plates are of equal density, they will 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. An example where this boundary has created a mountain rage is the Rocky Mountains in Colorado, Wyoming, Idaho, and Montana.]]> 2018-03-08 17:35:06 UTC https://padlet.com/2144668/n6rw3t9xkxw2/wish/239797706 2144668 https://padlet.com/2144668/n6rw3t9xkxw2/wish/239808566

The plate movement on the ocean floor can cause a tsunami.
Converging plates in subduction zones often become stuck. Pressure may build within rocks until they fracture. If the break is along hundreds of kilometers of fault line a megathrust earthquake occurs]]> 2018-03-08 17:55:23 UTC https://padlet.com/2144668/n6rw3t9xkxw2/wish/239810282 2144668 https://padlet.com/2144668/n6rw3t9xkxw2/wish/239812272 When plates slide past each other horizontally it is considered a transform boundary. At transform boundaries the lithosphere is neither created or destroyed. Many transform boundaries are found on the sea floor, where they connect parts of diverging mid-ocean ridges. California's San Andreas fault is a transform boundary.]]> 2018-03-08 17:58:33 UTC https://padlet.com/2144668/n6rw3t9xkxw2/wish/239812272 2144668 https://padlet.com/2144668/n6rw3t9xkxw2/wish/239815407

Friction in the rocks causes the plates to lock. The strain in the rocks slowly increases until they fracture. The sudden release of energy is what we feel during an earthquake.
The San Andreas Fault is the transform boundary between the North American Plate and the Pacific Plate. During the 1906 San Francisco earthquake the northern section of the San Andreas Fault slipped northward along the fault from San Juan Bautista to Cape Mendocino, a total of 296 miles.]]> 2018-03-08 18:04:20 UTC https://padlet.com/2144668/n6rw3t9xkxw2/wish/239815528 2144668 https://padlet.com/2144668/n6rw3t9xkxw2/wish/239820780 When two tectonic plates are separating it is called a called divergent boundary. At divergent boundaries new lithosphere is created as old lithosphere spreads away to either side.  An example of this boundary is the East African Rift. ]]> 2018-03-08 18:13:07 UTC https://padlet.com/2144668/n6rw3t9xkxw2/wish/239820780 2144668 https://padlet.com/2144668/n6rw3t9xkxw2/wish/239828299

Pillow basalt covers all the ocean floors. As new lava forms in the rift valley the tectonic plates continue to separate forming the global mid ocean ridge system that is the longest mountain range on Earth.]]> 2018-03-08 18:24:41 UTC https://padlet.com/2144668/n6rw3t9xkxw2/wish/239828383
