What plate boundaries show?
Deep ocean trenches, volcanoes, island arcs, submarine mountain ranges, and fault lines are examples of features that can form along plate tectonic boundaries.
What are the 3 types of plate boundaries provide an illustration?
There are three main types of plate boundaries:
- Convergent boundaries: where two plates are colliding. Subduction zones occur when one or both of the tectonic plates are composed of oceanic crust. …
- Divergent boundaries – where two plates are moving apart. …
- Transform boundaries – where plates slide passed each other.

How do you tell if a plate is divergent or convergent?
- Divergent boundaries — where new crust is generated as the plates pull away from each other.
- Convergent boundaries — where crust is destroyed as one plate dives under another.
- Transform boundaries — where crust is neither produced nor destroyed as the plates slide horizontally past each other.
What is convergent boundary?
When two plates come together, it is known as a convergent boundary. The impact of the colliding plates can cause the edges of one or both plates to buckle up into a mountain ranges or one of the plates may bend down into a deep seafloor trench.
What is a divergent boundary?
In plate tectonics, a divergent boundary or divergent plate boundary (also known as a constructive boundary or an extensional boundary) is a linear feature that exists between two tectonic plates that are moving away from each other.
What does a divergent boundary form?
A divergent plate boundary often forms a mountain chain known as a ridge. This feature forms as magma escapes into the space between the spreading tectonic plates.
What is the example of transform boundary?
Some transform plate boundaries pass through continental crust. An example of such a transform is the San Andreas Fault. Along the San Andreas Fault the Pacific plate moves in a northwest direction relative to the North American plate.
What happens in a convergent boundary?
Convergent (Colliding): This occurs when plates move towards each other and collide. When a continental plate meets an oceanic plate, the thinner, denser, and more flexible oceanic plate sinks beneath the thicker, more rigid continental plate. This is called subduction.
What does a transform boundary form?
Lesson Summary. The Earth's crust is split into sections called tectonic plates. Transform boundaries are where two of these plates are sliding alongside each other. This causes intense earthquakes, the formation of thin linear valleys, and split river beds.
What is an example of divergent boundary?
Divergent boundaries are typified in the oceanic lithosphere by the rifts of the oceanic ridge system, including the Mid-Atlantic Ridge and the East Pacific Rise, and in the continental lithosphere by rift valleys such as the famous East African Great Rift Valley.
What do divergent boundary create?
A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth's mantle to the surface, solidifying to create new oceanic crust. The Mid-Atlantic Ridge is an example of divergent plate boundaries.
What is an example of transform boundary?
The San Andreas Fault and Queen Charlotte Fault are transform plate boundaries developing where the Pacific Plate moves northward past the North American Plate. The San Andreas Fault is just one of several faults that accommodate the transform motion between the Pacific and North American plates.
What do convergent boundaries create?
A convergent plate boundary is a location where two tectonic plates are moving toward each other, often causing one plate to slide below the other (in a process known as subduction). The collision of tectonic plates can result in earthquakes, volcanoes, the formation of mountains, and other geological events.
