Oceanic plates are primarily made up of basaltic rock while continental plates are primarily made of granitic rock. Basalt is denser than granite which allows oceanic plates to subduct beneath continental plates.
There is no doubt that the oceanic plate is denser than the continental plate, however, it is thinner than the continental plate at the same time! The oceanic plate is made up of silicon and magnesium and other materials whereas the continental plate is made up of silicon and aluminum and other materials, therefore, the oceanic plates are denser and are below the continental plates.
in the theory of tectonic plates, at a convergent boundary between a continental plate and an oceanic plate, the denser plate usually subducts underneath the less dense plate. It is well known that oceanic plates subduct under continental plates, and therefore oceanic plates are more dense than continental plates.
My question is why are the oceanic plates always denser than the continental plates. I'm aware that the difference in density can be attributed to the plates differing compositions, but what I'm interested in is why these plates have different composition in the first place giving rise to their relative difference in densities.
An oceanic plate is more dense. The average density of continental crust is 2.7 grams per cubic centimeter. The average density of oceanic crust is 3.0 grams per cubic centimeter.
The Oceanic plate is denser than the Continental plate because it contains magnesium, which is denser than aluminum found in Continental plates.
The Oceanic plates are denser than the Continental plates because they contain magnesium, which is denser than aluminum found in Continental plates
because oceanic plates do not have to hold as much weight as the continental plats
the answer is 3
yes
No, the oceanic crust is denser. That's why the land areas "float" so much higher than the ocean bedrock.
When two oceanic plates or two plates both containing oceanic crust collide or converge, the convergent boundary will form a trench. The plate which has the higher density will plunge beneath the other plate forming a trench.
yes chalk is denser then water.
Because the oldest parts reach the continental crust and then the ocean floor sinks beneath the continental crust, into the mantle.
no
The Oceanic plate denser than the continental plat because it contain magnesium,which is denser than aluminum found in continental plates.
When an oceanic plate and a continental plate collide, the oceanic plate is always subducted. Oceanic plates are denser than continental plates, and they have a higher iron content. Since they are denser, oceanic plates always sink below the continental plate in the event of a collision.
The oceanic plate subduct under the continental because oceanic is made from basalt(rock) which is denser than andesite and granite(continental)
this is because the oceanic plate is much denser than the continental plate so when they collide the oceanic plate will sink easily
Oceanic plates move under continental plates when they converge together because the oceanic plate is more denser than the continental plate.
The Oceanic crust is denser than the continental crust
This is called a destructive plate boundary. It occurs due to the fact that the oceanic crust is far denser than the continental crust. As a result it subducts into the mantle and is incenerated. Hope it helped:)
No, oceanic plates move faster than continental plates. This is due to the density of the oceanic plates (basalt is denser). For example, the fastest moving plates are the Pacific plate, Cocos plate, and Nazca plate. All oceanic.
The oceanic plate is made of denser (and thinner) rock than the continental crust, so the oceanic plate gets subducted (pushed underneath) where it descends and gets melted by geothermal heat.
The oceanic plate (sea-floor plate) is denser than the continental plate, so the oceanic plate will be pulled under the continental plate (subduction) and into the upper mantle, creating an underwater volcano.
This process is known as subduction and occurs at convergent plate boundaries because oceanic crust is denser than continental crust.
Oceanic crust is thinner and denser than continental crust.
