No. The Earth's core and mantle would have cooled down by now (4500 million years of cooling) if the heat in the centre were just residual heat from the Earth's formation.
When the Earth was forming and entirely molten, all the heavy elements will have sunk into the core of the planet, separating themselves out into layers of increasing density (this layering would have been disturbed somewhat by convection movements). This would mean that the very heavy radioactive elements would have moved to the core and it is the decay processes of these that is keeping the interior of the earth hot and has been driving plate tectonics and volcanic activity. In essence the planet is a slow fission reactor/bomb.
You may well ask - if all the heavy elements sank, why can we find any at the surface now? - and the answer to that is that a second wave of heavy elements was delivered to the planet after the surface had solidified/cooled, in the late heavy bombardment (which is probably when Earth's) water was delivered too.
What else can I help you with?
How much heat does the earths mantel?
The Earth's mantle is responsible for generating most of the planet's heat through radioactive decay of elements like uranium, thorium, and potassium. It is estimated to produce around 47 terawatts of heat energy. This heat drives geological processes like plate tectonics and mantle convection.
Which layer contains most of the earths mass?
The Mantle
Most of Earth's volume is contained in the?
Most of Earth's volume is contained in the mantle, which is the layer between the crust and the core. The mantle makes up about 84% of Earth's volume and is composed of solid rock that can flow slowly over long periods of time.
Name three elements that make up most of earths mantle?
The rocks in earths mantel are made up of 44.8% oxygen, 21.5% silicon, and 22.8% magnesium. Iron, calcium, sodium, aluminum, and potassium are also present. The elements occur in rocks as oxides.
Ost geologists thinks that the movement of earths plates is caused by?
Most geologists believe that the movement of the Earth's plates is caused by the process of convection currents in the mantle. These currents are driven by the heat generated from the core of the Earth, which causes the molten rock in the mantle to move in circular patterns, leading to the movement of the tectonic plates.
Most of the earth's heat is stored in earth's mantle true or false?
True. The majority of Earth's heat is stored in the mantle, which is the layer of Earth located between the crust and the core. This heat is generated by the decay of radioactive elements and leftover heat from the planet's formation.
Where would you be most likely to find granite in earths mantle or earths continents?
you will find it in earths mantle because it is a kind of an igneous rock
What is most of the earths mass in?
Most of the mass of the Earth is in the mantle, most of the rest in the core; the part we inhabit is a tiny fraction of the whole

Where is the most volume at in earths layers?
Most of earth's volume has been scientifically proved to be in the earth's mantle.
What layers makes up most earths mass?
The Mantle. It is the largest and thickest layer in the earth. But this answer might not be actually true. Because the earth has all these layers and the mass is added up. -By Olivia Agbo A 12 year old. Thank you for your support.
Is it true that earths crust contains most of earths mass?
No. The crust contains a small fraction of earth's mass. Most of the mass is contained in the mantle.

What is the source of most of earths heat and natural li?
sun
Where is most of the earths new crust found?
Most of Earth's new crust is found along mid-ocean ridges, underwater mountain ranges where tectonic plates are moving apart. This is where magma rises from the mantle to create new crust through volcanic activity.
