Plate Boundaries By austin larison

Convergent Boundaries

Convergent boundaries are boundaries that move closer to each other and crash. 2 continental boundaries that crash together will crumble up at where they crash to form mountains. This is called a compression tension when it compresses together.
This is a photo of Mount Fuji. It was created by convergent plate boundaries. 2 continental plate boundaries crashed together. Where it impacted, it crumbled up and formed the mountain.
As the Oceanic lithosphere dives underneath the continental lithosphere, it creates a deep spot in the ocean called a trench. The ocean is full of trenches. The deepest trench is almost 7 miles below the ocean, that is 36,201 feet deep.
Mount Santa Maria located in Guatemala, was a volcano created by convergent plate boundaries. When an oceanic crust subducted underneath a continental plate it created a subduction zone. Magma from underneath rose to the top and created this volcano.

Divergent Plate boundaries

Divergent plate boundaries are plates that move away from each other. This type of stress in called tension. The crust will pull away like pulling taffy and will create ocean ridges, volcanoes, or rifts.
This is a picture of the mid ocean ridge. 2 continental plates move in the opposite direction. Magma from the mantle rises to the bottom of the sea floor and and creates new land at the mid ocean ridge.
This is a volcano that is in the East African rift. the 2 continental plates, possibly the light brown on the left and right, have spread apart. in the middle 2 volcanoes were made from magma rising int he middle of the 2 continental plates. the land in the middle is the newest.

Transform plate boundaries

Transform plate boundaries are plates that move across from each other. This is called a shear force. When they move across from each other they can create faults and rivers
This is a picture of the San Andreas fault, the big gap in the middle, shows where the 2 plates on both sides of the gap have moved across from each other. the small mountains are land that has been stretched sideways.
This is a picture of a river that was once large. rivers that cross from one side of a transform boundary to the other side, one side of the river can be cut off and it will eventually dry up.
