Where is energy source found that drives the processes that form igneous and metamorphic rocks?
Mantle convection
Why do tectonic plate's move?
Tectonic plates are composed of the crust and upper mantle rock which is lighter than the more dense mantle. Rising and falling convection currents in the mantle cause imperceptibly slow movements in the plates (on the rate of fingernail growth). The source of the heat driving the convection currents comes from residual heat from the Earth's formative processes, pressure from gravity, and from radioactive decay of elements.there is also something called the slab-pull force. This occurs when a more dense oceanic plate subducts under a less dense plate and pulls the rest of the plate along. The subducting plate drives the downward-moving portion of convection currents.
What is the source of magma for intraplate volcanism?
Rift zone
A very long lived magma source located deep in the mantle is called?
The term hot spot is used to describe a very long-lived magma source located deep in the mantle. J. Tuzo Wilson is credited with having originated the concept of hot spots.
Parts of tectonic plates that are located above mantle plumes are called?
The part of the tectonic plates located above mantle plumes are called "hot spots". --- Source(s) : Does Google count?
What is the main source of downward convection flow in the mantle called?
slab-pull
Is the heat source for the convection currents in the mantle for the sun?
The difference in temperature and density is the cause of convection currents in the earths mantle. Convection currents are the flow that transfers heat within a fluid.

Does the heat source for the convection currents in the mantle in the sun?
Bad grammar.
Is this truth or false the heat source for the convection currnets in the mantle is the sun?
False.
Is the sun the heat source for the convection currents in the mantle?
The heat in the Earth's interior comes from two main sources: the radiogenic heat produced by the radioactive decay of isotopes in the mantle and crust and the primordial heat left over from the formation of the Earth.
Where is the energy source found that drives the processes that form igneous rocks?
Mantle convection
Where is energy source that drives the processes that form igneous and metamorphic rocks?
Mantle convection
Where is the energy source found that drives the processes that form igneous and metamorphic?
Mantle convection
Is the heat source for the convection currents and the mantle the sun?
No. It's radioactive decay within the planet.
What is the heat source driving the convection current in earth's mantle?
Radioactive decay - mainly of potassium.
