What is the difference between oceanic and continental plates?
Continental plates are thicker and less dense. Continental plates are mainly granitic in composition. Oceanic plates are mainly basaltic in composition. The rock of continental plates is on average, much older than the rock of the oceanic plates. The oceanic plate underlies the oceans, and the continental plate makes up the land masses. Continental plates do not subduct at convergent plate boundaries.
Why does subduction occur at some tectonic plate boundaries?
Subduction occurs at convergent plate margins where plates are moving toward each other. Subduction occurs as old oceanic crust becomes thicker and more dense than the upper mantle directly below it. Because it is more dense, it is forced under younger, less dense oceanic crust, or under continental crust, which is always less dense. At these borders of collision, the older and more dense oceanic crust is drawn by gravity downward, into the mantle, where it is slowly melted. The two basic forces responsible are gravity and heat.
How is continental lithosphere different from oceanic lithosphere?
Continental plates are thicker and less dense. Continental plates are mainly granitic in composition. Oceanic plates are mainly basaltic in composition. The rock of continental plates is on average, much older than the rock of the oceanic plates. The oceanic plate underlies the oceans, and the continental plate makes up the land masses. Continental plates do not subduct at convergent plate boundaries.
What happens when a plate gets subducted?
The colder, more dense plate is the one that subducts in a collision between two plates. In an oceanic to oceanic plate collision it is the older of the two plates that will subduct due to its higher density. In an oceanic to continental plate collision, it's the oceanic plate that will subduct because of its higher density.
What is the Law of Superposition?
Superposition is the principle that states that, in undisturbed strata, newer layers will be deposited over older layers; thus, in a core sample, those samples of earth and rock nearest the surface will be newer in age than those beneath them.

Why would newer rock layers ever be below older rock layers?
Due to faulting or folding.
What happens when an oceanic crust colides with another oceanic crust?
The younger of the two plates, because it is less dense,* will ride over the edge of the older plate.
What is the difference between older and newer airbags?
newer are better
How much does it cost to transfer plates and title in Illinois?
There is not a set specific cost to transfer the title and plates on a vehicle in Illinois. The cost will depend on the make, model, and year of the vehicle.
Are the layers of rock above and below the coal older or younger?
Every layer of rock, as one moves up from the core, is younger than the one below it. This means that the layers of rock above and below the coal are different ages, with the one above younger and the one below older.
Do you need Eu plates to drive in France or will a GB sticker do?
The French renew their old plates only when the car registration is updated (for a change of the owner's address, or a change of owner). Older cars do not have to switch to the newer "EU plates" in France and the sticker of the country of origin (GB in your case) will be enough.
What happens when oceanic plates meet?
If the plates are moving toward each other from opposite directions, the more dense oceanic plate will subduct in a conveyor belt like operation under the less dense continental plate. Transform plate boundaries occur where plates of any combination grind alongside each other and result in faults and earthquakes.
What is the difference in older day and newer day phones?
newer day are longer distance

Can you playPS2 pgames on PS3?
on the older models from 60gb and below...the newer ones cut that feature to reduce the price 100$ to make it more affordable to people
