What is the outcome of the collision between oceanic and continental crust?
Usually subduction of the denser thinner oceanic crust under the lighter thicker continental crust. This also produces a row of volcanoes in the continental crust producing lava high in water content and resulting in explosive eruptions.
How does subduction effect Volcanoes?
Subduction zones involve an oceanic plate sliding beneath either a continental plateor another oceanic plate (that is, the subducted plate is always oceanic while the subducting plate may or may not be oceanic). Subduction zones are often noted for their high rates of volcanism, earthquakes, and mountain building. This is because subduction processes result in melt of the mantle that produces a volcanic arc as relatively lighter rock is forcibly submerged.
What process is evident at oceanic trenches?
subduction, which is when one tectonic plate is pushed down beneath another tectonic plate.
What is a subduction zone and how can you identify whether you live near one?
A subduction zone is the area where an oceanic plate is being pushed downward in a collision with a continental plate. There is usually an offshore trench and several inland volcanos whose eruptions are of the explosive type (due to trapped water in the lava). Another form of subduction zone produces island arcs containing volcanos instead of producing inland volcanos.
What boudaries produces volcanoes?
Convergent boundaries produce volcanoes. Volcanoes form when an oceanic plate and a continental plate converge, causing the oceanic plate to subduct. The subduction causes a magma chamber to form which feeds the volcano when it erupts.
Places where the seafloor is forced under continental plates?
The region where the seafloor is forced beneath the continental plate is called a subduction zone. When the seafloor descends down it produces a deep-ocean trench.
How are the mountains that are formed by subduction diffrent from mountains formed by continental crusts converging?
Subducting crust produces volcanoes and a narrow range of mountains (like the Andes). Continental convergence does not produce volcanoes and produces a wider range of mountains (Rockies or Himalayas).
Ocean convergence produces what?
Ocean convergence with continental plates result in subduction zone. Oceanic with oceanic plates convergence forms volcanic mountain.
Magma that is low in silica generally produces what kind of eruption?
It produces a quiet eruption.

Usually subduction of the denser thinner oceanic crust under the lighter thicker continental crust. This also produces a row of volcanoes in the continental crust producing lava high in water content and resulting in explosive eruptions.
What are the differences between pahoehoe and AA What kind of eruption produces these type of lava?
The differences are that Pahoehoe produces fast moving lava; Aa produces slower moving lava. The kind of eruption that produces these types of lava is a quiet eruption.

Which natural event produces aerosols?
A volcanic eruption.

Volcanoes can erupt due to the blank of plates that produces heat for the rock to melt?
Subduction.
