It has a divergent boundary with the Explorer Plate off the west coast of Vancouver Island, Canada. The eastern and southeastern parts of the Pacific Plate jostles against the Juan de Fuca, Cocos, and Nazca Plates, which are subducting under the North American Plate.
What causes the motion in the two types of divergent plate boundaries?
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. Two plates sliding past each other forms a transform plate boundary.
What are the types of convergent?
There are three types of convergent boundaries each with its own consequences.
- Oceanic-Continental Convergence.
- Oceanic-Oceanic Convergence.
- Continental-Continental Convergence.
What happens when two continental plates collide at a convergent boundary?
If two tectonic plates collide, they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction. The new magma (molten rock) rises and may erupt violently to form volcanoes, often building arcs of islands along the convergent boundary.
Which type of plate is thicker continental or oceanic?
Continental plates are much thicker that Oceanic plates. At the convergent boundaries the continental plates are pushed upward and gain thickness. The rocks and geological layers are much older on continental plates than in the oceanic plates. The Continental plates are much less dense than the Oceanic plates.
What are the consequences of convergent oceanic and continental plates?
Effects of a convergent boundary between an oceanic and continental plate include: a zone of earthquake activity that is shallow along the continent margin but deepens beneath the continent, sometimes an ocean trench forms immediately off shore of the continent, a line of volcanic eruptions a few hundred miles inland …
What two interacting plates from the transform fault boundary?
The collision led to the subduction of the Farallon plate underneath the North American plate. Once the spreading center separating the Pacific and the Farallon plates was subducted beneath the North American plate, the San Andreas Continental Transform-Fault system was created.
