What forms at a subduction zone?
Volcanic arcs and oceanic trenches commonly form at subduction zones.
How do convergent and transform boundaries cause earthquakes?
It can cause earthquakes, volcanoes, oceanic trenches, mountains, tsunamis, and subduction.
Name areas prone to volcanic eruptions?
The Circum-Pacific Belt, or also known as the Pacific Ring of Fire, accounts for about 80% of earthquakes and volcanic eruptions that occur in a year, and is home to about 68% of Earth's volcanoes.
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.
What does an oceanic-oceanic convergence give rise to?
volcanic island arcs
What forms when oceanic plates collide?
1. Oceanic trenches. 2. Volcanic islands. 3. Volcanic mountains. and 4. Volcanic arcs.
Where is basalt located?
Basalt is generally found on and near volcanoes.
What does an oceanic-oceanic convergence rise to?
volcanic island arcs
What do oceanic vs oceanic convergence produce?
volcanic island arcs
Fine-grained black rock that makes up the oceanic crust?
Basalt.
What geologic events occur most often at this mid-oceanic ridge plate boundary?
earthquakes and volcanic eruptions because 2 plates are pushing against each other causing the crust to rise
Volcanic island arc are associated with what type of plate boundaries?
convergent oceanic oceanic
