The slow circulation of the plastic mantle in the earths asthenosphere occurs by what processes?
convection
What are three words that describe earths mantle?
It's only soft and plastic in that it is not as hard as the brittle rock of the crust and uppermost mantle.
What is the surface on which the lithospheric plates move around earths surface?
Lower mantle is the surface on which the lithospheric plates move around earths surface.
Which temperature is inferred to exist within Earths plastic mantle?
2000 celcius
Why does solid rock in earths mantle melt?
Rocks do not melt in the mantle; however, they may exhibit certain plastic-like or liquid-like properties.
Theory that states that earths crust and upper mantle are broken into sections which move around on a spcial layer of th emantle?
plate tectonics

Earths Litosphere Is Broken Into Separate Sections Called?
Earths lithosphere is made up of upper mantle. The earths lithosphere is broken into separate sections and it is called as tectonic plates or plate tectonics.

What is oceanic and continental plates?
These are individual broken slabs of gigantic masses, that makes up the earths crust and are capable of floatational movement over the weak, plastic, hot and highly molten portion of the mantle called the asthenosphere.
What is the theory that states that earths crust and upper mantle move around on a speacial layer of the mantle?
Plate tectonics.
How many layers in earths mantle?
there are 7 layers in earths mantle.
What states that the earths lithoshere is broken into huge moving slabs of rock driven by motions in the mantle?
The theory of plate tectonics states that the lithosphere is broken into moving pieces of earth driven by convection currents located inside the mantle.
Earths middle layer?
the mantle
