If two tectonic plates collide, they form a convergent plate boundary. The new magma (molten rock) rises and may erupt violently to form volcanoes, often building arcs of islands along the convergent boundary. When two plates are moving away from each other, we call this a divergent plate boundary.
Can a convergent boundary become a divergent boundary?
For example, sections of Earth’s crust can come together and collide (a “convergent” plate boundary), spread apart (a “divergent” plate boundary), or slide past one another (a “transform” plate boundary).
What are the 2 types of divergent boundaries?
At divergent boundaries, sometimes called constructive boundaries, lithospheric plates move away from each other. There are two types of divergent boundaries, categorized by where they occur: continental rift zones and mid-ocean ridges. Continental rift zones occur in weak spots in the continental lithospheric plate.
Which is the best example of a convergent plate boundary?
Answer: The Washington-Oregon coastline of the United States is an example of this type of convergent plate boundary. Here the Juan de Fuca oceanic plate is subducting beneath the westward-moving North American continental plate. The Cascade Mountain Range is a line of volcanoes above the melting oceanic plate.
Which is the result of convergent, convergent and transform plate boundaries?
Inch by inch, this accounts for incredibly long distances over millions of years. Continents collide creating a supercontinent cycle. Then, they detach again into a new configuration. All the result of convergent, divergent and transform plate boundaries. This is a deep-dive into plate tectonics.
How are the different types of plate boundaries different?
Plate boundaries interact with each other in 3 primary ways. The types of plate tectonic boundaries are divergent, convergent, and transform (conservative). DIVERGENT PLATES: Divergent plates pull apart from each other. CONVERGENT PLATES: Convergent plates push boundaries together.
How are convergent boundaries formed in the mantle?
Convergent boundaries are boundaries where two plates are pushing into each other. They are formed when two plates collide, either crumpling up and forming mountains or pushing one of the plates under the other and back into the mantle to melt.
What happens when a continent is broken apart by a divergent boundary?
Rift valleys develop when a continent is broken apart by a divergent boundary. Now, as plates pull apart, several things may occur. First of all, volcanic activity is common in these areas since mantle easily moves to the surface through the thin, fractured rock as it separates.
