What are the division of lithosphere?
Upper lithosphere, containing the continental crust/plate, known as the SiAl, and the Lowwer lithosphere composed of the oceanic crust/plate also reffered to as SiMa.
How does oceanic crust form at constructive plate margins?
Do you mean spreading centres or oceanic ridges, where the oceanic lithosphere is renewed by hot, less dense rock rising in convection zones.
Give the name of one plate that contains mostly oceanic lithosphere and of one plate that continenmental litosphere?
The Pacific plate is mostly oceanic lithosphere while the North American plate is mostly continental lithosphere.
How big is the indo-australian plate?
No, it is not an oceanic plate. It is a continental plate but with oceanic crust. Crust is different from plate. A plate is made up of many crust. The crust under the ocean is oceanic crust, while the crust where continent is found is called continental crust. Most of the plates are made up off both continental and oceanic crust. If a plate has continental crusts, then it is a continental plate. Only if a plate is all made up of oceanic crusts, meaning that there is no land on it, then the plate is called oceanic plate. In the world, the major oceanic plates include Pacific Plate, Nazca Plate, Cocos Plate and Philippines Plate. Other are all continental plate.
Why is the oceanic plate subducted when an oceanic plate collides with a continental plate?
The Oceanic plate is subducted under the Continental plate because oceanic crust is much more dense than continental crust. The average density of the oceanic crust is 3g/cm^3 while the average density of continental crust is 2.7g/cm^3.
What are the division of lithosphere?
Upper lithosphere, containing the continental crust/plate, known as the SiAl, and the Lowwer lithosphere composed of the oceanic crust/plate also reffered to as SiMa.
What is a section of the lithosphere that slowly moves over the asthenosphere carrying pieces of continental and oceanic crust?
Together the crust and upper mantle are called the lithosphere and they extend about 80 km deep. The lithosphere is broken into giant plates that fit around the globe like puzzle pieces.
According to the plate tectonic theory a plate can be made up of?
A tectonic plate consists of a piece or fragment of the earth's lithosphere, which is in turn composed of the earth's crust and that portion of the earth's upper mantle which behaves as a brittle solid through which fractures can propagate.
How does oceanic crust form at constructive plate margins?
Do you mean spreading centres or oceanic ridges, where the oceanic lithosphere is renewed by hot, less dense rock rising in convection zones.
Do the pacific plate have more oceanic lithosphere or more continental lithosphere?
Oceanic. Most of the Pacific plate is under the Pacific Ocean.
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.
Do lithospheric plates include both continental crust and oceanic crust?
It is possible to have continental and oceanic crust on the same plate. The only to this exception is with the Pacific plate which exists independently.
Give the name of one plate that contains mostly oceanic lithosphere and of one plate that continenmental litosphere?
The Pacific plate is mostly oceanic lithosphere while the North American plate is mostly continental lithosphere.
What is the lithosphere made up of?
The solid outer zone of the Earth is the lithosphere. The lithosphere is made up of the upper layer of the mantle and the crust of the Earth.
What is oceanic-oceanic subduction?
Oceanic crust sinking under a plate with continental crust
How big is the indo-australian plate?

What is slabpull?
Slab Pull Force occurs when a denser oceanic plate is forced beneath a less dense continental plate or oceanic plate in a process called subduction. It's the force caused by suction of the cold dense lithosphere into the asthenosphere at destructive margins. Basically, because lithosphere is denser than asthenosphere, there is gravitational imbalance which is passed on to the crust. this causes the lithosphere to be sucked inwards at the oceanic trenches into deep asthenosphere.
