What do plates float on?
Upper mantle
Is the oceanic crust a thick layer?
Continental plates are thicker and of lower density than oceanic plates. They float like giant rock icebergs deeply embedded in the upper part of the mantle, while oceanic plates form more of a surface skin on the top of the mantle.
Which layer of the earth do the plates ride on?
The layer of the mantle that supports the plates is the aestenosphere. The plates and fluid upper mantle are referred to collectively as the lithosphere.
Are plates composed of the crust and part of the upper mantle?
That is correct.
The crust and upper mantle are called the?
The crust and the upper mantle are a geological part of the earth called the lithosphere. There are 2 parts of the lithosphere: the oceanic lithosphere, which is made up of land underneath water, and the continental lithosphere, which is the the part made of just land. The lithosphere lies on top of the asthenosphere. The lithosphere is made up of tectonic plates, which are pieces of land floating on the lithosphere.
What are the oceanic plates pushed down in the upper mantle in?
Subduction Zones.
What are oceanic plates pushed down in the upper mantle in?
Subduction Zones.
Ocean plates are pushed down into the upper mantle in what?
Subduction Zones.
What is composed of oceanic continental crust and upper mantle?
That would be the lithosphere which is split into tectonic plates.
What is composed of oceanic or continental crust and upper mantle?
The crust and upper mantle consist of hard rocks which form the moving plates of the outer layer of Earth.
What is oceanic lithosphere?
The lithosphere is composed of crust and hard upper mantle. The oceanic lithosphere would be hard upper mantle and basaltic oceanic crust.
What is the oceanic lithosphere?
The lithosphere is composed of crust and hard upper mantle. The oceanic lithosphere would be hard upper mantle and basaltic oceanic crust.
What is the rigid part of the tectonic plates that is made up of oceanic crust or continental crust and the upper mantle?
the lithoseshere
What are the subdivision of lithosphere?
Lithosphere is categorized into two sections. They are crust and upper most mantle. Crust includes continental and oceanic crust and technology.
What layer of earth makes up the plates?
the crust + lithosphere earth's crust: crust crust continental crust lithosphere crust continental and oceanic crust mantle asthenosphere mantle lower mantle mantle outer core outer core inner core inner core
Which layer of the earth contains the tectonic plates?
The plates are part of the crust, the upper layer of the Earth. The plates are moved by currents in the upper mantle. The plates and flexible upper mantle are referred to collectively as the lithosphere and sit atop the mantle layer called the aesthenosphere.
What do plates float on?
Upper mantle
