What else can I help you with?
Where is subduction most likely to occur?
Where an oceanic plate dives under a continental plate (e.g. just offshore the Washington/Oregon coast, creating a line of explosive volcanos just inland).
Which boundaries are likely to result in volcanic island arcs?
Volcanic island arcs are likely to result from convergent boundaries where an oceanic plate subducts beneath another oceanic plate or a continental plate. The subducted plate can melt, causing magma to rise and form a series of volcanic islands above the subduction zone.
What plate collisions would most likely result in a subduction zone?
Convergent plate boundaries where an oceanic plate collides with a continental plate or another oceanic plate are most likely to result in a subduction zone. In this scenario, the denser oceanic plate is forced beneath the less dense continental plate, creating a subduction zone.
What convergent plate boundaries are active volcanoes not likely to be located?
Active volcanoes are not likely to be located at convergent boundaries where an oceanic plate subducts beneath a continental plate because the melting point of the oceanic crust is lower, causing it to melt and create volcanic features before reaching the surface. Instead, active volcanoes are more commonly found at divergent boundaries where plates move apart.
Which type of plate boundaries produce volcanoes?
Continental and Oceanic plates.

When are mountains most likely to form at convergent boundary?
When two continental plates collide or a continental plate collides with an oceanic plate.
Which type of plate boundaries produce volcanoes?
Continental and Oceanic plates.
What is the Amount of mass in a given volume it determines which plate will subduct at convergent boundaries?
At convergent boundaries, the amount of mass in a given volume, known as density, determines which tectonic plate will subduct. Typically, oceanic plates are denser than continental plates, so when they converge, the denser oceanic plate sinks beneath the lighter continental plate. This process is influenced by factors such as temperature, composition, and the age of the plates, with older oceanic crust generally being denser and more likely to subduct.
How was the Andes Mountains and Cascade Mountains most likely formed?
A convergent boundary between an oceanic plate and a continental plate.
Why is oceanic crust always subducted underneath the continental crust?
Oceanic crust is denser and thinner than continental crust, making it more likely to be subducted beneath the less dense continental crust. This process occurs because the denser oceanic crust is pulled downward into the mantle at convergent plate boundaries due to gravitational forces. The subduction of oceanic crust beneath continental crust helps to recycle Earth's materials and plays a key role in plate tectonics and the geologic cycle.
Where would you be most likely to find a boundary between a continental and an oceanic plate?
You would be most likely to find a boundary between a continental and an oceanic plate along a convergent boundary, where the denser oceanic plate subducts beneath the less dense continental plate. This often leads to the formation of deep-sea trenches and volcanic activity.
When are mountains most likely to form at a convergent boundary?
Mountains are most likely to form at a convergent boundary where two tectonic plates collide, with one plate being forced beneath the other in a process called subduction. The intense pressure and heat generated during this collision cause the crust to deform and uplift, leading to the formation of mountain ranges.
What feature would most likely be formed at convergent continental tectonic plate boundaries?
At convergent continental tectonic plate boundaries, the most likely feature formed is a mountain range. This occurs due to the collision and compression of two continental plates, leading to the uplift of the Earth's crust. An example of this is the Himalayas, which were formed by the collision of the Indian and Eurasian plates. Additionally, intense geological activity such as earthquakes is common in these regions.
