When Volcanoes found where two oceanic plates collide form at a what?
When volcanoes are found where two oceanic plates collide, they form at a subduction zone. This is where one plate is being forced underneath the other plate, creating intense heat and pressure that leads to volcanic activity.
What is the effect of a hot spot on an existing volcano?
They will all dies xdHot spot often lie in the middle of continental or oceanic plates far from any plate boundaries.
Why continental rock is younger than oceanic rock?
The Oceanic Plates are younger than the continental because they are "recycled"; think of the oceanic ridges, such as the mid Atlantic oceanic ridge, that is where a hot spot under diverging plates (plates moving apart) push magma up, causing new young ocean floor to spread from this spot, and pushing the old floor into trenches and other continents, being destroyed. Another point to remember is that the ocean crust is thicker the farther away from the ridge; this is because it has had more time to build itself up compared to the more thin young crust.
Does Kilauea happen at a converging boundary?
No. Kilauea is on a hot spot.
Where does subdution occur?
Subduction (I believe that's what you meant) occurs at CONVERGENT boundaries, where two plates collide and the less dense one remains and the denser one sinks. An example of subduction is two oceanic plates colliding. Oceanic plates contain mainly basalt, which is dense. The oceanic plate closer to a heat source (hot spot, volcano) would remain in place while the denser plate sinks (cold water is denser than hot water so it sinks) below the other. When an oceanic plate and a continental plate collide, the oceanic plate sinks because granite (what continental plates are composed of mainly) is less dense than basalt, therefore the oceanic plate would sink. However, when two continental plates collide, because both plates are made of granite and are not very dense, they push and shape the land into mountains.
How do how spot volcanoes?
A hot spot develops above the plume. Magma generated by the hot spot rises through the rigid plates of the lithosphere and produces active volcanoes at the Earth's surface. As oceanic volcanoes move away from the hot spot, they cool and subside, producing older islands, atolls, and seamounts.
What forms along converging oceanic plate boundaries?
At converging oceanic plate boundaries, one form that can develop is a deep ocean trench where one oceanic plate is subducted beneath another. This process can also lead to the formation of volcanic island arcs, created from magma rising up through the subducted plate. Additionally, earthquakes are common along these boundaries due to the intense pressure and friction between the plates.
Is rabaul on a convergent or divergent or a hot spot?
Rabaul is located near the boundary between the Pacific and Australian tectonic plates, where they are converging. This convergence has resulted in the formation of the New Britain Trench and the associated volcanic activity in the region, including the eruption of Tavurvur and Vulcan volcanoes.
Where volcanoes occur?
volcano occur in hot spot and diverging boundaries and converging boundaries.
What features form at a hot spot.?
They form volcanic mountains by heating magma that breaks through the crust. On the oceanic plates, these crustal hot spots can form chains of volcanic islands such as the Hawaiian Islands.
Do hot spots create or destroy oceanic or continental crust?
Hot spots do not create or destroy oceanic or continental crust. Hot spots are volcanic regions that are stationary relative to moving tectonic plates. As the plates move over the hot spot, they experience volcanic activity, which can result in the formation of volcanic islands or seamounts, but the crust itself is not created or destroyed in the process.
Are volcanic eruptions caused by the movements of tectonic plates?
Usually, volcanic eruptions above water are the result of a magma-plume burning through a spot in the Earth's crust, or by the rising part of a magma convection cell. Such conditions are often found near the edges of the continental plates. There are also spots where the Earth's crust is so thin that magma breaks through even without there being a plume, such as near oceanic ridges. Most of the volcanic eruptions on this planet take place under water, near oceanic ridges.
