Is the mantle heated mainly by the heat conducted from the core?

No, the main heat source for the mantle (as well as the core) is radioactive decay of elements like uranium within the mantle itself (or core, respectively). Heat rising from the core into the already hot mantle does set up the differential heat profile that drives much of the mantle convection, but even without the additional core heat the mantle would convect (but slower) so that its heat would rise to the crust.

What is the order of the earth's inner layers?
Crust, mantle, outer core, inner core
Earth is composed what of main three layers?
Crust, mantle, and core
Is earth divided by composition into three layers?
The 3 main layers of earth (crust, mantle, core) are divided into crust, upper mantle, lower mantle, outer core, and inner core.
How thick is each 8 layer of the Earth?
There are five basic layers of the Earth, being the crust, upper mantle, inner mantle, outer core, and inner core. Of these, the lithosphere is composed of the crust and upper mantle, and the asthenosphere is part of the mantle, below the lithosphere.
What are. The three parts of the earth?
The core, mantle and the crust. (There is an inner and outer core, and an inner and outer mantle.)
What is earths mantle heated by?
the earths Mantle is heated by the lava that is under neath the Mantle
What is the layer of hot solid material between earth's crust and outer core?
There are several layers between the outer core and the crust mainly combined into one and called the Mantle.
What among the crust the mantle and the core has the highest density?
The core, as it is mainly made up of iron and nickel.
What is the difference between the mantle and outer core of the Earth?
There are differences in chemistry (the mantle is mainly ultramafic rock--the outer core is metallic), in phase (the mantle is predominately solid--the outer core is liquid), in depth (the outer core is closer to the center of the Earth), and in density (the outer core is more dense).
Magma forms when rocks begin to melt?
Yes. Magma is underground molten rock.
Define earth's mantle?
It is mainly solid and is located between the outer crust and core.
What are convection currents and where are they found?
Convection currents in the mantle are streams of fluid produced by the process of heat transfer from one place to another. The earth gets very hot as you go nearer to the core. The mantle is thus heated up as it is right next to the core. As a result, convection currents are formed.*Core: It is a spherical zone that lies at the center of the earth.*Mantle: It is the layer surrounding the outer core of the earth.
Which layer is the coolest?
The Crust Is The Coolest One I Think because it isn't made of of layers that are heated like the core or mantle ...
How is the earth's mantle like a peanut butter and jelly sandwich?
In the mantle,we have two layers of solid rock with heated flowing rock between them.
What is the rock that is liquid?
the layer in the earths suface that contains liquid rock is called: the inner core (mainly)\ outer core (some) and (parts) of the mantle.
What is the layer that is liquid?

What are the 3 things that are heating up the earth core and mantle?
Neutrons are! The core is heated by the neautrons and so the the cor heats the mantls and so thats what melts and heats the rest of earths core parts.
