In which layer of earth do convection current occur?
in the mantle due to the molten rock... hope this helps!!! =] also for better detail they happen in the asthenospheric mantle to
What layer makes up most of the earths volume?
ANSWER: The crust floats on the asthenospheric mantle, which is convecting due to the forces of plate tectonics. The mantle, which extends to a depth of nearly 3,000 kilometers is the source of all magma. The mantle makes up 84% of the earth's volume and can sometimes get as hot as 3700°C. ==== ====
Does the lithosphere contain the crust?
Yes the lithosphere does contain the crust. The lithosphere is the rigid outermost shell of a planet. It is composed of the upper mantle and the crust. The upper mantle is made of solid rock and is divided into two layers; the lithospheric mantle and the asthenospheric mantle. The lithospheric mantle is the layer closest to the crust and is much thicker and more rigid than the asthenospheric mantle. The crust is made up of two types of rocks: oceanic and continental. The oceanic crust is made up of dense iron- and magnesium-rich rocks while the continental crust is composed of lighter rocks such as granite and sandstone.

Which of the Earth's layers is located just below the mantle?
Upper Mantlemantle
What are the 2 types of mantle?
the upper mantle(lithosphere)and the lower mantle(mesosphere)
What are the Asthenospheric mantle and the Inner Mantle are made up of?
The Asthenospheric mantle and the Inner mantle are made up of solid rock and liquid rock.

Why is subduction important?
ubduction zones are important for several reasons[citation needed]:Subduction Zone Physics: Sinking of the oceanic lithosphere (sediments + crust + mantle), by contrast of density between the cold and old lithosphere and the hot asthenospheric mantle wedge, is the strongest force (but not the only one) needed to drive plate motion and is the dominant mode of mantle convection.Subduction Zone Chemistry: The subducted sediments and crust dehydrate and release water-rich (aqueous) fluids into the overlying mantle, causing mantle melting and fractionation of elements between surface and deep mantle reservoirs, producing island arcs and continental crust.Subduction zones drag down subducted oceanic sediments, oceanic crust, and mantle lithosphere that interact with the hot asthenospheric mantle from the overriding plate to produce calc-alkaline series melts, ore deposits, and continental crust.Subduction zones have also been considered as possible disposal sites for nuclear waste, in which the action of subduction itself would carry the material into the planetary mantle, safely away from any possible influence on humanity or the surface environment. However, this method of disposal is currently banned by international agreement.[10][11][12][13] Furthermore, plate subduction zones are associated with very large megathrust earthquakes, making the effects on using any specific site for disposal unpredictable and possibly adverse to the safety of long-term disposal.[11]
How does the outer mantle differ from the inner mantle?
the inner mantle is different than the outer mantle because the inner mantle is hotter than the outer mantle.
What are the part of the mantle?
The upper mantle and the lower mantle.
Which of the Earth's layers is located just below the mantle?
Upper Mantlemantle
How does the outer mantle and the inner mantle differ?
the inner mantle is hotter than the outer mantle.
