Convergent Boundaries.
a constructive plate boundary is where two plates move apart from eachother forming a gap which allows magma to rise and that leads to a earthquake.
At the western edge of the Nazca plate and the eastern edge of the Pacific plate lies the East Pacific Rise. The East Pacific Rice is known as a mid-ocean ridge, formed from a divergent boundary.
The force that occurs at divergent boundaries is a convection force. This force allows material to rise to the base of the lithosphere beneath each divergent plate boundary.
It is formed by a convergent boundary of an oceanic plate and continental plate when they hit each other and goes down into the asthenosphere thus making the magma to rise above the earth's surface making a volcano.Then it solidifies and therefore it makes a volcano island.

The East Pacific Rise is a site of major seafloor spreading in the Ring of Fire. The East Pacific Rise is located on the divergent boundary of the Pacific Plate and the Cocos Plate (west of Central America), the Nazca Plate (west of South America), and the Antarctic Plate.

The volcano erupted due to it lying on a destructive plate boundary, where the denser North American Plate, was sinking underneath the less dense Caribbean Plate causing a subduction zone. As the two plates merge the oceanic plate is forced down or sub-ducted under the continental plate. As it is forced down pressure increases which triggers earthquakes and at the same time heat produced by friction melts the descending crust to form molten magma. The hot magma tries to form molten magma to rise to the surface and when it succeeds it will create a volcano like the one we have here.
To understand this, we must first undertand why volcanoes form at convergent and deivergent boundaries. The material in earth's mantle is not molten, despite its extremely high temperature because it is under immense pressure. At a divergent plate boundary the crust is thinned, which reduces pressure on the upper mantle, allowing some of the rock to melt. This molten rock then rises up thoguh the crust to form volcanoes. At convergent boundaries where at least one plate is oceanic, an oceanic plate plunges into the mantle. The subducting plate takes water with it. This water seeps into the mantle, lowering the melting point of the rock, and allowing it to melt and rise to the surface. At a transform plate boundary, plates simply slide past each other, and there is nothing that will lead to the melting of mantle material.
The Himalayas resulted from the collision of the Indian Plate into the European plate. The softer Indian Plate was forced underneath the harder European Plate, which caused the European Plate to rise up and form the Himalayas.
The plate boundary at the East Pacific Ridge(Rise) is a diverging boundary. Ridges usually occur where two boundaries are diverging(seperating, or spreading apart, thus creating a ridge. -Textbo7
