Is japan on a hot spot?
No. The volcanic activity in Japan is associated with a subduction zone.
What is produced by underwater volcanic activity?
obcidien
When an oceanic plate is pushed under a continental plate resulting in volcanic activity what type of boundary is formed?
Convergent Boundary (Subduction Zone)
Volcanic activity how does it happen?
Volcanic activity happens with the gases saved and stored build up and explode. =] ~Anna 6th Grade California Volcanic activity happens with the gases saved and stored build up and explode. =] ~Anna 6th Grade California
What type of rock does volcanic activity produce?
Extrusive igneous rock is produced by the solidification of lava.
How do subduction zones lead to the formation of volcanic activity?
Subduction zones lead to the formation of volcanic activity because the water combined with crust and mantle material lowers the rock's melting point temperature, causing the rock to melt and produce magma, which then creates volcanic activity.
Is japan on a hot spot?
No. The volcanic activity in Japan is associated with a subduction zone.
What is very common in subduction zones?
trench volcanic activity Island Arc
What is the difference between the volcanic activity that occurs at a hot spot and the volcanic activity at a subduction boundary between an oceanic plate and a continental plate?
The hot spot volcanic activity is not dependent on the subduction and melting of oceanic crust. The hot spot simply appears to be a non-moving place in the Earth's mantle where heat rises from the interior.
What is produced by underwater volcanic activity?
obcidien
Why are volcanoes not found in Singapore?
Although Singapore is not very far from a subduction zone, it is beyond the zone in which the subduction produces volcanic activity. Additionally, Singapore is geographically quite small, so even if it were in a belt of volcanic activity, there probably would not be a volcano in Singapore.
Which feature can be produced at an ocean-continental convergence?
Parallel belts of folded mountains and volcanic mountains
Which of these would be the best indications that a given mountain range was not formed by subduction?
No oceanic coastline Absence of volcanic activity
How were the hawaiian islands made?
They were all produced by volcanoes.
What are two major geologic features produce near a plate boundary where subduction occurs?
volcanic activity and growing mountain ranges
When an oceanic plate is pushed under a continental plate resulting in volcanic activity what type of boundary is formed?
Convergent Boundary (Subduction Zone)
When an oceanic plate is pushed under a continental plate resulting in volcanic activity this type of boundary forms what?
it causes subduction <-- wrong convergent <-- right
