Much of the heat in the core of the Earth is residual from heat created billions of years back, and some of this was created in fusion reactions in stars.
There are other nuclear actions at work in the core of the Earth, however. The more important of these is nuclear decay, which is what most radioactive atoms undergo. This releases energy in the form of heat, which is the trapped underground until it can escape - a very long time. Less commonly, some isotopes, most notably uranium-235, undergo fission. This is a much more energetic process, but is not common because there is not much of this isotope around.

How has nuclear fusion always warmed Earth from the outside?
Ever since the earth formed and the sun burst into light, the sun's light, which is created from nuclear fusion on our local star, has warmed the earth from the outside. Sunlight is directly responsible for the continuation of life on earth. If the sun suddenly went dark, most life on earth would die, and the rest would freeze solid in a ball of ice.
What layer that is warmed from below by the ozone?
The stratosphere is the layer that is warmed from below by the ozone layer. Ozone absorbs ultraviolet radiation from the sun, which causes the stratosphere to warm up as the ozone molecules absorb and release this energy. This process creates a temperature inversion where the upper stratosphere is warmer than the lower stratosphere.
Is there another name for nasal passage on each side of the inside of your nose?
The nasal passage on each side of the inside of your nose is also known as the nasal cavity. This is the part of the respiratory system where air is warmed, filtered, and humidified before reaching the lungs.
What passages does the air get warmed and cleaned?
Air gets warmed and cleaned as it passes through the nasal cavity, where it is humidified, filtered, and warmed by the mucus and tiny hairs called cilia. Additionally, the air is further warmed and cleaned in the trachea and bronchi by the same mechanisms of mucus and cilia before reaching the lungs.
How is earth warmed inside by?
Earth is warmed from the inside primarily through the process of radioactive decay of isotopes such as uranium, thorium, and potassium found in the Earth's crust and mantle. This decay generates heat, contributing to the planet's internal temperature. Additionally, residual heat from the planet's formation and heat generated by the movement of tectonic plates also play significant roles in warming the Earth's interior. Together, these processes maintain the geothermal gradient, which influences volcanic activity and the dynamics of the Earth's interior.
How is it that radioactive decay has always warmed the earth from the inside and nuclear fusion has always warmed the earth from the outside?
That's because of where each of these processes occur. There is no nuclear fusion inside of Earth. There is probably a small amount of radioactive decay in the Sun, but the power produced by it is insignificant, compared to the huge amount of power produced by nuclear fusion.
Explain how radioactive decay has always warmed the earth from the inside and how nulear fusion has always warmed the earth from the outside?
The Earth's core contains many radioactive elements within its core that emit warmth as they decay, keeping the core of the Earth hot and heating it from within. Meanwhile, the sun is a product of the nuclear fusion of hydrogen into helium and its rays warm the Earth's crust from outside.
How has nuclear fusion always warmed Earth from the outside?
Ever since the earth formed and the sun burst into light, the sun's light, which is created from nuclear fusion on our local star, has warmed the earth from the outside. Sunlight is directly responsible for the continuation of life on earth. If the sun suddenly went dark, most life on earth would die, and the rest would freeze solid in a ball of ice.
Water from a natural hot spring is warmed by what inside the earth?
It is warmed by geothermal energy which is created by RADIOACTIVE DECAY http://en.wikipedia.org/wiki/Geothermal_(geology)
What is the hollow space inside the head where air is warmed before entering the lungs and where nerves that detect smells are located?
The sinuses.
Why does a flat basketball seem inflated when warmed?
Because the heat causes the air inside the basketball to expand, which increases the pressure in the ball.
What does a Dry Hot Dog Bun Warmer do?
The buns are place inside the bun warmer, with the lid on, and they are slightly warmed before serving.
What happens to the air pressure inside a tire when it is warmed?
The warming air would expand and the tyre pressure would go up.
What happens to a film of bubble solution when the air inside a bottle is warmed and cooled?
When the air inside the bottle is warmed, it expands, creating pressure that can cause the film of bubble solution to expand and create larger bubbles. Conversely, when the air is cooled, it contracts, leading to lower pressure that can cause the bubble film to shrink and create smaller bubbles.
What is the whole world warmed at?
The whole world is warmed by the sun.
How does hot air balloon stays up?
The air inside the balloon is heated with a propane burner. As air is warmed, it becomes less dense (lighter) and rises.
Why does ford diesel 6.0 not start after its warmed up?
The problem is a leak inside the high pressure oil system. When it is hot the leak expands and causes the truck to not start.
