Molten rock rises primarily at divergent plate boundaries, where tectonic plates move apart, allowing magma from the mantle to ascend and fill the gap. This process occurs in mid-ocean ridges, where new oceanic crust is formed as magma erupts. Additionally, convergent boundaries can also lead to the rise of molten rock, particularly when an oceanic plate subducts beneath a continental plate, causing melting and the formation of volcanic arcs.

What type of plate boundary is the indo-australian plate and pacific plate?
The boundary between the Indo-Australian Plate and the Pacific Plate is mainly a divergent boundary in the region of the East Pacific Rise and a transform boundary along the Tonga Trench and the Alpine Fault in New Zealand. Additionally, there are some regions of convergence near New Zealand and the New Hebrides Trench.
What is the boundary type between pacific plate and the nazca plate?
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.
What type of plate boundary is the southeast Indian ridge?
The southeast Indian Ridge is a divergent plate boundary, where two tectonic plates are moving away from each other. This movement causes magma to rise from the mantle, creating new crust as the plates separate.
Why is the boundary of the Narca plate along the east pacific rise a divergent boundary rather than a convergent one?
The boundary of the Nazca Plate along the East Pacific Rise is a divergent boundary because it is where tectonic plates move apart, allowing magma to rise and create new oceanic crust. This process of seafloor spreading occurs as the Nazca Plate moves away from the Pacific Plate, leading to the formation of new material at the mid-ocean ridge. In contrast, convergent boundaries involve plates moving toward each other, typically leading to subduction or mountain building, which is not the case at the East Pacific Rise.
What type of plate boundary causes mountains to rise?
Convergent plate boundaries cause mountains to rise. This is where tectonic plates collide, forcing one plate to be pushed up and over the other, leading to the formation of mountain ranges. Examples of this type of boundary include the Himalayas, created by the collision of the Indian and Eurasian plates.
What are examples of plate boundary?
Mid-Atlantic Ridge and East Pacific Rise
What does conservative plate boundary mean?
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.
What type of boundary is the east pacific ridge?
The East Pacific Rise is a divergent plate boundary where tectonic plates are moving apart. This boundary is associated with seafloor spreading and the creation of new oceanic crust.

What type of plate boundary is the Galapagos Rift?
The Galapagos Rift is a divergent plate boundary, where tectonic plates are moving apart. This movement creates a gap that allows magma to rise from the mantle, forming new oceanic crust.
How are volcano island formed?
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.
Why chances peak erupted?
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.
What type of plate boundary is Hekla the volcano formed?
A diverging is the type of plate boundary that the Hekla volcano formed. Hekla last erupted in 2000. It is located in Iceland. ADDED. Also called a "constructive" plate boundary, because the upwelling magma adds rock to the edges of the two plates.
