Because the Earth's crust is composed of not one solid layer like a shell, but many pieces, like in a puzzle. These plates are floating on layer of magma. So at these fault lines it is easier for lava to get through the crust and cause volcanoes and such.... yeah

What boundary do subduction zones form on?

Subduction zones form along some tectonic plate boundaries. Of the three general types of tectonic plate boundaries, we will see them form at some (but not all) of what are called convergent plate boundaries.


What types of plate boundaries are found in or along the continental US?

The types of plate boundaries found in or along the continental US are primarily transform boundaries, where the Pacific Plate and the North American Plate slide past each other, creating faults like the San Andreas Fault in California. Additionally, subduction zones are found along the west coast, where the Juan de Fuca Plate is being subducted beneath the North American Plate.


Is the geothermal gradient associated with divergent plate boundaries greater than the gradient associated with subduction zones?

The geothermal gradient associated with divergent plate boundaries is typically lower than the gradient at subduction zones. This is because at divergent boundaries, the crust is thinning and heat can more easily escape from the mantle, while at subduction zones, the subducted plate can carry heat deeper into the Earth, increasing the geothermal gradient.


What types of boundaries do subduction zones form?

This forms on the plate tectonic boundaries.... particularly the convergent plate boundries.


Are most plate boundaries on continents or in ocean basins?

Most plate boundaries are located in ocean basins rather than on continents. This is because oceanic plates are denser than continental plates, leading to subduction zones and mid-ocean ridges where most of the plate boundaries are found in the oceans.

Subduction zones are found near what kind of boundaries?

Subduction zones are found near convergent plate boundaries, where two tectonic plates collide and one plate is forced beneath the other, leading to the formation of deep ocean trenches and volcanic arcs.

Where is Ocean crust being destroyed?

At subduction zones along convergent plate boundaries.


What plate boundaries are the most destructive?

Convergent plate boundaries tend to be the most destructive because they involve the collision of tectonic plates, leading to intense seismic activity, volcanic eruptions, and the formation of mountain ranges. Subduction zones, where one plate is forced beneath another, are particularly hazardous due to the potential for powerful earthquakes and tsunamis.


What is another name for subduction zones?

Convergent plate boundariesDestructive plate boundaries


What pattern do you see among plates boundaries earthquakes and volcanoes?

most earthquakes occur at the plate boundaries because the plate boundaries are the weakest zones and earthquakes are likely to occur there . you can also take help from science ncert of 8 class.


Where do fault lines usually occur?

Fault lines usually occur at the boundaries between tectonic plates, where the Earth's lithosphere is divided into large, rigid plates that move and interact with each other. These boundaries can be found along mid-ocean ridges, subduction zones, and transform faults, where the movement of the plates relative to each other creates stress that can result in earthquakes.


How are earthquakes distributed on the map Are they scattered evenly or concentrated in zones?

Earthquakes are not distributed evenly on the map but are concentrated in specific zones known as seismic zones or fault lines. These zones are usually located along tectonic plate boundaries where the Earth's crust is under stress and prone to movement. The most seismically active areas include the Pacific Ring of Fire, the Himalayan belt, and the Mid-Atlantic Ridge. These zones experience more frequent and intense earthquakes compared to other regions around the world.
