What types of tectonic plate boundaries are volcanoes generally found?

Continental and Oceanic plates.


Why are earthquakes mainly found at the edges of plates?

Earthquakes are mostly found at the edges of plates because that is the area of which the plates collide in different ways resulting in earthquakes and volcanoes.


Why are volcanoes found at the earth's moving plates?

As the Earth moves the plates back and forth, the plates collide bending upward and with enought pressure, it creates a volcano.


How do volcanoes form at boundaries?

Volcanoes are usually found where tectonic plates are diverging (pulling apart) or converging (coming together). A mid-oceanic ridge (Mid-Atlantic Ridge) has examples of volcanoes caused by divergent tectonic plates that are pulling apart. The Pacific Ring of Fire has examples of volcanoes caused by convergent tectonic plates that are coming together.


How are volcanes formed?

Volcanoes form when tectonic plates move on the surface of the earth. It occurs at transform plate boundaries. Tectonic plates are always moving slowly, but when an oceanic plate converges with a continental plate, it creates a Subduction zone known where volcanoes are found.


Is it true that many volcanoes are found in island arcs that form where two oceanic plates collide?

Yes! When two oceanic plates collide, one of the plates subducts beneath the other. As the subducting plate sinks, it releases volatiles (such as carbon dioxide and water) into the mantle. This addition causes the mantle to melt in the places where it mixes with volatiles. The melted mantle is less dense than the surrounding mantle, so it slowly rises until it reaches the surface. When the melted mantle reaches the surface, it is considered a volcano. Over many years, these volcanoes build up the sea floor and may eventually break the surface. Now, these volcanoes have become volcanic islands, and usually occur as a string (an arc) of volcanic islands that follow the plate boundary.


Where can igneous rocks be commonly found?

Igneous rocks can commonly be found near volcanoes. They are made when lava is cooled and becomes a solid. The oceanic plates are mostly made of igneous rock.


Why are no volcanoes found in certain parts of world?

Volcanoes are only found on the edge of tectonic plates & they can also be found on cracks in the tectonic plates which is un-common


What is formed when one tectonic plate slide under another tectonic plate?

Depends on the type of tectonic plate. If it is two continental plates, usually a mountain range will be formed and the plates will 'lock' together due to their thickness. The Indian sub-continent colliding with the eurasian plate is one example. If an oceanic plate is subducting under a continental plate an island arc can be formed or mountain range such as Japan and the Andies mountains respectively. This type is also where volcanoes will be commonly found unlike the collision of two continental plates, due to the magma formed from the subduction of the oceanic plate. If two oceanic plates collide, usually form an oceanic mountain range and lock together similar to the continental plates.


Where in geographic location is oceanic plate found?

Oceanic plates form the 'floors' of the worlds oceans.


How are fossils of sea life found on mountains?

First you have to understand what mountains are. Earth's crust is formed of plates of either oceanic or continental crust. When two continental plates collide, the sediments which formed on the ocean floor between them and some of the oceanic crust are squeezed by the colliding plates into lots of folds. The folds start to erode as they are slowly pushed upwards, but the upward movement is more than the rate of erosion. These are your mountains, and the fossils found there are in the old oceanic sediments.


Where are earthquakes and volcanoes typically found?

Earhquakes and volcanoes are typically found near the edges of tectonic plates.


Is runny lava found in continental or oceanic plates?

Ocean


Where is most of the basalt or granite on earth?

Most basalt is found in the oceanic plates. Most granite is found in the continental plates.


Where do most volcanoes occur?

Most volcanoes are found near the edges of tectonic plates.


Where is Basalt found?

Basalt is found by comparing oceanic plates beneath the ocean floor.


Why is the oceanic plate less dense than the continental plate?

The Oceanic plates are denser than the Continental plates because they contain magnesium, which is denser than aluminum found in Continental plates


Is there a pattern in the location of volcanoes?

Yes, there is. Volcanoes are usually found where Tectonic Plates Diverge and Converge.


Are volcanoes found in the center of a plate?

Sometimes, but not usually. Most volcanoes are near the edges of plates.


Where can the oldest oceanic crust be found?

It can be found in the mid-oceanic ridge. The age of rocks or plates increases as one moves away from the rift zone.


Where are tilted blocks of rock commonly found?

where two continental plates collide


Where is the most of the basalt found on earth?

Most Basalt is found mostly in oceanic plates of Earth.


Why do you think volcanoes are found in a line?

because of the tectonic plates


Which biome includes volcanoes?

They are found in most oceanic biomes and near most islands.


Why are volcanoes found along the Rift Valley?

Because it is on the edge of the plates
