Why does subduction occur?
Subduction happens when two tectonic plates collide. The earth's crust is made up of separate plates that 'float' on the mantle below. They are always moving, and when two move together, one will slide under the other. For instance, the subcontinent of India is colliding with the continent of Asia.
How arelassen peak and mt shaSTA related to subduction?
Mount Shasta and Lassen Peak are both volcanoes located in the Cascade Range in California. These volcanoes are related to subduction because they are situated above the subduction zone where the Juan de Fuca tectonic plate is being forced beneath the North American plate. This subduction process creates magma chambers beneath the Earth's crust, leading to volcanic activity in the region.
Explain how the formation of the Lassen Peak and Mouny Shasta are related to subduction?
Lassen Peak and Mount Shasta are both stratovolcanoes formed due to the subduction of the Juan de Fuca plate beneath the North American plate. As the Juan de Fuca plate subducts, it melts, leading to the formation of magma that rises to the surface and erupts, forming these volcanic peaks. Subduction zones are known for producing explosive eruptions due to the interaction between the descending plate and the overlying plate.
Why are Oceanic trenches found only in association with subduction zones?
The trenches are evidence that one of the colliding plates is moving beneath the other. As the two plates move together, one gets pushed below the other. The place where this sinking/bucking occurs creates a deep trench. The deepest of which is Marianas trench about 7 miles deep.
What type of structure has formed where the juan de fuca plate is subducting beneath the north American plate?
There was an earthquake about 500 years ago that caused a tsunami that hit the coast of Japan, according to my Geology professor at Pierce College in Puyallup, WA. The earthquake was about 9.0 on the richtor scale, and hit in the fall of 1700, as recorded in Japan. Generally, what happens at that subduction zone is the Juan De Fuca, the last reminent of the Ferallon plate, is subducting under the North American plate due to collision, creating the orogenic belt.
Do most volcanoes form near colliding plate boundaries?
Most volcanoes do form near colliding plate boundaries where subduction occurs, such as the Ring of Fire in the Pacific Ocean. However, volcanoes can also form in other geologic settings, such as hotspots and rift zones.
What mountain range has an oceanic plate and continental plate colliding?
Fold mountains.

Why are there few volcanoes in the Himalaya?
There is no subduction occurring.
Why do you have earthquakes in California?
because shifting of plates colliding together

Why are subduction zones not commonly found at continental-continental boundaries?
because the subduction eventually brings the two continents together.
Why are subduction not commonly found at convergent continental continental boundaries?
because the subduction eventually brings the two continents together.
Why are subduction zones not commonly found at convergent continentals-continental boundaries?
because the subduction eventually brings the two continents together.
Why are subduction zones not commonly found at convergent continental- continental boundaries?
because the subduction eventually brings the two continents together.
Is subduction constructive or destructive?
It is neither, because plate is not being made or destroyed. Divergent is constructive. Convergent is destructive. Subduction is constructive.
Why are subduction zones not commonly found at convergent continental continental-continental boundaries?
because the subduction eventually brings the two continents together.
