Heat that drives mantle convection comes from?
The heat that drives mantle convection comes from the colling of Earth's interior and the decay of radioactive isotopes
Does the magma and lava from a volcano come from the mantle?
Yes it does , The magma finds gaps through the crust ( oceanic or continental) and comes up as a volcano. It is originally in the mantle.
What is the layer below the earths crust called?
the mantle then the outer core then the inner core
Where does the heat come from that drives this convection current the mantle?
The heat comes from the outer core, which provides the heat.
Is the Asthenosphere the bottom part of the mantle?
Yes it is and the lithosphere is the upper part, to remember this think of L.A. The L comes first which is the lithosphere and the A comes second which is the asthenosphere
Does the mantle contain volcanism?
No. Volcanism occurs at the surface on the crust. However, the magma that drives volcanism ultimately comes from the mantle.
How do volcanoes make the lava?
they dont; the lava comes from the mantle in the earth
Are the hot rocks under ground part of the mantle?
No. it comes from the core
Where do you get your magma from?
Magma comes from the melting of material in the crust or upper mantle.
Heat that drives mantle convection comes from?
The heat that drives mantle convection comes from the colling of Earth's interior and the decay of radioactive isotopes
How does convection currents form in the mantle?
Chuck Norris comes and makes it >:D

The heat comes from the outer core, which provides the heat.
Where does molten rocks come from?
It comes from the melting of material within the Earth's mantle. Moltan Rock comes from the lava chambers, the temperature makes the bits of sedimaentary and igneouse rock wich is made into lava , all the time this takes place in the earths inner third the mantle.
Is the Asthenosphere the bottom part of the mantle?
Yes it is and the lithosphere is the upper part, to remember this think of L.A. The L comes first which is the lithosphere and the A comes second which is the asthenosphere
Which part of the Earth is the source of magma?
Lava is magma that reaches the surface. Magma originates either from rising plumes of heat at hot spots in the Earth's mantle, where decompression melting takes place as the hot rock nears the surface; or, it originates in the mantle from subduction of oceanic crust, where cold, wet rock speeds melting of the subducting rock and it rises toward the surface.
