Plate Boundary images and captions
After reading pages 50-60, post an image and a summary of what occurs at each type of plate boundary, in the space below. To avoid plagiarism, cite the source of your images and make sure your summaries (captions) that go with your posted images are not too similar to the words used to describe similar images, written by other people. DO NOT SAVE WORD DOCUMENTS! Upload images that show up, when the page is opened. There are actually FIVE types of plate boundaries, so you should have 5 images and 5 captions (summaries). Here is the list of the plate boundaries: Divergent, Oceanic-Continental Convergent, Oceanic-Oceanic Convergent, Continental-Continental Convergent, Transform Fault.

Divergent boundaries happen when the lithosphere is pulled away from eachother and tilt away from eachother.
Oceanic Continental Convergent-
Sediments and oceanic crust have a big amount of water which is carried in depths by a subducting plate.
This can carry volcanos.
Where an oceanic plate slides beneath a continental plate and contributes to the rise of magma to the surface. At divergent margins, volcanoes tend to form as two oceanic plates pull together.
Continental- Continental Convergent-
No plates subduct. The two plates converge and come together to form mountains. For example, the Himalayans.
Transform faults are locations of recurring earthquake activity and faulting. For example, the
California line because that's where most earthquakes occur in the United States.

: creates a new crust either once or twice.
: this is the last type of boundry. Its where the plates diagnally interact with each other
: they repare themselves . Sometimes they recylce and make news crusts .
this is a picture of all the different types of plate boundries and how they happen to contract.

: This is showing the plates moving away from the ridge axis and the cracks are being
filled with molten rock that wells up from the mantle on the bottom.
One plate goes under another with heatforcing magma or other substances to go
deeper into the mantle.
Here, one plate is going another another. The lithosphere goes under the continental crust
The plate also goes under another in this picture. The asthenosphere is all the way on the bottom
and the lithosphere goes deeper by it. The plates on the surface also merge together.
Transform Fault Boundary:
In this boundary, plates slight past each other.The fraction zone is the transform fault. Most of these faults
are found in the ocean basins.

Divergent boundaries can be though of as constructive plate margins because this is where new oceanic crust is created. New oceanic crust are formed when two or more plates pull away from each other. This is how oceans are born and it grows wider where plates diverge or pull apart.
Convergent boundaries is where crust is destroyed and recycled back into the inside of the Earth. This happenes when one plate dives under another.
A)When an oceanic and continental plate collide with each other, the overriding continental plate is lifted up and a volcanic arc is created.
B)When two oceanic plates become one, one gets subducted under the other and due to this a deep oceanic trench is formed.
C)When two continental plates collide with each other, the crust gets pushed upward or sideways and a mountain range is formed.
Transform fault boundaries occures when plates slide horizontally past one another without the production or destruction of lithosphere.
Image and info from:
Divergent boundaries can be called spreading centers becuase the floor of the ocean splits at the boundaries. When they split oceans form or any kind of water from takes place.
convergent plates happen when plates move toward each other. When pushing together ocean trenches are formed, and lithospheric parts rise when melted.
Oceanic continental onvergence happens when once again the one slab of oceanic land hits land and one falls beneath the other. It continues to fall to the pont of 100 kilometers causing melting and eventually a volcanic eruption.
Oceanic-oceanic convergence is when one ocean slab is pushed underneath the other. The water triggers melting in the mantle. This is how volcanoes appear from the ocean surface and not on land.
Continental continental convergence happens when two plates of landforms push together causing one to push downwards. When this happens landforms like mountains form.
Tramsform fault occures when plates slide past one another. enventually they form two parts of the oceans ridge. When looking at it it looks as if it was a staircase "zig-zaging" past each other.
When two continents meet, the continent don't stop because the continental rocks are light and resist downward motion. Instead, the crust tends to buckle and be pushed upward or sideways
When Earth’s lithosphere gets pulled apart, it breaks along parallel faults that tilt outward. When the plates separate, a block between the faults cracks and drops into the asthenosphere, which forms a rift. Magma fills the cracks and then a new boundary is formed.
OOceanic-Oceanic Convergent: Formed when two oceanic plates come together, one is usually pushed under the other and then a deep oceanic trench is formed.
Transform Fault: A fault which runs along the boundary of a tectonic plate and the motion of a plate is horizontal going in different directions. They sometimes set off active spreading ridges.
Oceanic-Continental Convergent: When an oceanic plate pushes into and under a continental plate, the overriding continental plate is lifted up and a mountain range is created. The oceanic plate sinks under the trench and breaks into smaller pieces.

Divergent Boundaries: Are usually located long the fronts of oceanic ridges and is where seafloor spreading takes place. This is an example of how magma comes up through the asthenosphere and hardens thereby spreading the ocean floor.
Oceanic- Continental Convergent: Occurs when a large piece of oceanic crust collides with continental crust and slides into the Lithosphere and melts into the Asthenosphere.
Oceanic-oceanic Convergence: Occurs when two lagre pieces of oceanic crust collide and one is pushed under the other rising the water and triggering melting in the mantle ultimately creating a volcano above the surface of the water.

= occur when two of the earths plates move away from each other causing a gap in the middle.
= Occurs when the plates move against each other causing one to go under neath.
= happens when continental plates meet and come together. Causing one to raise and create a mountain.
= Occurs when the plates of the oceanic crust meet. Making one rise over the other.
t= is when the two of the earths plate move right past each other.

When a oceanic plate moves under a continental one.
When 2 oceanic plates meet and 1 moves over the other.
When 2 continental plates meet and on goes over the other.
When 2 plates move past each other.
. A plate boundry that seperates apart form eachother and the sea floor spreads apart.
boundary that converges together and the older crust sumberges down.
When two plates rub agaisnt eachother.
oceanic oceanic convergence-
-boundary where 2 oceanic plates come together and can form together and make a trench or under water volcanoe.
Continental- continental convergence-
a collision between 2 continents where it can be shortened or thickened. it can make mountains, volcanoes, etc.
. when this happens the oceanic crust which is the denser one submerges under creating magma to rise and an explosion in a volcanoe.

Divergent plate boundaries are positions where plates are moving apart from one another, occurs when convection currents are risings.
When an oceanic plate pushes into and causes subduction under a continental plate, the dominating continental plate is lifted up and a mountain range is created.
The two oceanic plates converge one is usually under the other and in the process a deep oceanic trench is formed.
When two continents meet head-on, the continental rocks are relatively light and, like two colliding icebergs, resist descending movement.
Two plates are sliding horizontally past one another.
