How does heat flow in the mantle?
My guess: its almost like boiled water. you know how the steam rises? same with the heat from the magma in the mantle. The magma itself is around 500-900 degrees celcius, so the heat is much less by the time it makes it to the surface of the earth. that is my guess
If the mantle and the core are extremely hot why is the heat coming from these layers not felt on the earths surface?
Rock is a very poor conductor of heat and there is quite a lot of it between the surface and the mantle. As a result heat conducts to the surface very slowly and quickly radiates into space. As a result the vast majority of heat at Earth's surface comes from the sun. The heat from the mantle is felt at erupting volcanoes where magma, which ultimately gets it heat from the mantle, reaches the surface.
When rocks return to the Earth's mantle they can eventually melt and become magma. and are the main factors that control this change.?
pressure and heat
How does magma or lava cool down after erupting?
Anything that is warmer than its surroundings will transfer heat to them and cool down in the process. Lava from a volcano transfers heat to the air, which then carries it away. Underground magma transfers heat to the surrounding rock. Since rock is a poor conductor of heat the magma will cool much more slowly than if it were at the surface.
When rocks return to earth's mantle they can eventually melt and become magma eroison and weathering are the main factors that control this change?
heat and pressure
What helps heat the earth?
The outer core and the mantle, which are filled with magma.

What is a surface expression of a plume of magma rising from a stationary source of heat in the mantle?
A hotspot volcano.
The pressure and heat that produces magma are caused in part by?
Radioactive elements
Area in the Earth's mantle hot enough to melt rock into magma and create volcanoes?
All of the Earth's mantle is hot. And while some geologists believe that there are Mantle plumes (or hot spots) current evidence seems to support a view that mantle plumes do not exist. What causes magma to rise up from the lower crust and mantle is the convection of the mantle and therefore the places where most heat (and magma) is coming up to the surface is along the mid oceanic ridges.
What part of the earths mantle that flows and moves the plates of the earth?
Mantle plumes are in the mantle, BELOW the Earth's crust. The circulation of heat from the lower mantle to the upper mantle can cause "hot spots" in the overlying crust, heating the magma in the areas.

How does convection current occur in the mantle?
radioactive decay takes place, which produces lot of heat and causes the mantle to flow in convection currents veena
