How will angle at which an oceanic plates is subducted affect the distance from the volcanic arc to the trench?

∙ 8y ago
The distance from the volcanic arc to the trench can be determined only by the dip of the angle of the subducting slab. A narrow and deep oceanic trench is formed along the subducting side of the island which the trace of Earth's surface between overriding and downgoing plates.

∙ 13y agoThe steeper the subduction angle, the closer the arc will be to the trench. This is controlled by the age of the oceanic crust being subducted where in general the older the crust, the cooler and more dense it will be and so less buoyant and will sink more steeply.

How does the force of gravity affect tectonic plates?
Gravitational sliding:Plate motion is driven by the higher elevation of plates at ocean ridges. As oceanic lithosphere is formed at spreading ridges from hot mantle material it gradually cools and thickens with age (and thus distance from the ridge).
How does explosive volcanic effect the Earth's four spheres get effec?
Explosive volcanic eruptions affect the Earth's spheres by introducing volcanic substances into these spheres. Tons of volcanic gases and water vapor can spread through the atmosphere, lithosphere and hydrosphere. These gases are then inhaled by the organisms in the biosphere, which could lead to health problems.
How might a volcanic eruption affect the abiotic factors in an organism's habitat?
By destroying the homes of animals etc...
How does volcanic ash affect climate patterns?
yes, look at the mini ice age in the 18th century
How does volcanic activity affect carbon dioxide?
it seperates the diatomic molecule and makes it a monotomic molecule, or carbon monoxide
What are two factors that can affect the distance that volcanic ash can travel?
The blast of the volcano, the wind, and how light the ash is all affect how far it will travel.

How does distance and time affect the speed from object?
Distance and time do not, in general, affect the speed. Speed, however, can affect distance or time. Distance is directly proportional to speed, time is inversely proportional.
A volcanic eruption can affect the atmosphere by?
adding large quantities of several gases, such as sulfur dioxide, to the atmosphere as well as volcanic ash and dust.
Does a line on a graph become less steep when the distance increases?
No. The distance of a line on a graph will not affect how steep it is. Distance does not affect slope.
