The core of the sun is the region that extends from the center to about 20–25% of the solar radius. It is here, in the core, where energy is produced by hydrogen atoms (H) being converted into nuclei of heliu.
This is the zone immediately next to the core, which extends out to about 0.7 solar radii.
This is the sun's outer layer, which accounts for everything beyond 70% of the inner solar radius (or from the surface to approx. 200,000 km below). Here, the temperatur.
Lastly, there is the photosphere, the visible surface of the sun. It is here that the sunlight and heat that are radiated and convected to the surface propagate out into space. Te.Energy production in the sun occurs through the following process12:Core: Hydrogen atoms are converted into helium nuclei, releasing energy.Radiative Zone: Energy is transported outward through radiation.Convective Zone: Energy is transported through convection.Photosphere: The visible surface of the sun where energy is emitted as sunlight.

How does the sun produce energy? The sun produces energy through nuclear fusion. This is when smaller atoms come together to form a larger atom. This process releases a lot of energy in the form of heat and light. The sun is uniquely placed to be the centerpiece of our solar system because it produces its own energy. The sun produces energy
The core is the only region of the Sun that produces an appreciable amount of thermal energy through fusion; 99% of the Sun''s power is generated in the innermost 24% of its radius, and almost no fusion occurs beyond 30% of the radius. The rest of the Sun is heated by this energy as it is transferred outward through many successive layers

Mar 8, 2017· Knowing now how much energy the sun produces, it is easy to see that we are not using this energy to its fullest potential. Instead of continuing to rely on forms of energy that pollute the earth and drain the planet of fossil fuels, it is time to turn to the sun, since it produces more energy in one second than the entire planet needs.
The large power output of the Sun is mainly due to the huge size and density of its core (compared to Earth and objects on Earth), with only a fairly small amount of power being generated per cubic metre.
Energy is created through fusion of hydrogen into helium at the center of the Sun. This energy first enters the radiative region of the Sun, where photons are absorbed and reemitted in random directions until they make it about 2/3 of the way to the surface. Once the energy has traveled 2/3 of the way to the surface, it reaches the convection zone where the hot gas flows up and down
Nuclear fusion is the source of all energy the Sun releases into space. If the fusion rate is varied, so would the Sun''s energy output, and large variations in the Sun''s luminosity would almost surely be lethal to life on Earth. Why does the energy produced by fusion in the solar core take so long to reach the solar surface? Describe the
