In what way is energy transported outward through the Sun’s interior?
Inside the Sun, conduction is ineffective (the Sun is not solid). Energy is transported by convection in the outer regions of the Sun (the outer 30 percent, or so). Energy is transported by radiative diffusion in the inner regions of the Sun (the inner 70 percent).
How is energy transferred within the Sun?
Radiation is the transfer of heat energy through space by electromagnetic radiation. Most of the electromagnetic radiation that comes to the earth from the sun is invisible. Only a small portion comes as visible light. Light is made of waves of different frequencies.
How is energy transferred from the core of the Sun to its outer layers?
Energy is radiated out from the core first, then carried to the outer layers by convection. Energy is carried out from the core by convection first, then radiated to the outer layers.
Does the Sun’s energy travel outward?
The Sun's energy, which is produced in the core, travels outwards. The energy travels first through the radiative zone, where particles of light (photons) carry the energy. It actually takes millions of years for a photon to move to the next layer, the convection zone.
Is the sun radiation convection or conduction?
Conduction, the collisional transfer of energy between atoms, only occurs between solids (such as a hot pan and your hand), so is not found in the Sun. Convection is the motion of heated material, such as bubbles in boiling water. Radiation is the transfer of energy by electromagnetic waves (light).
How is energy transported from the core to the surface of the sun by radiation and by convection?
Explanation. Energy is transferred through electromagnetic radiation in the radiation zone. In this process, the particles repeatedly absorb and re-emit the waves until they reach the outermost part of the radiative zone. On the other hand, the energy is transferred through convection currents in the convection zone.
What is the order of how energy is transported from the sun’s core to its surface quizlet?
The energy generated in the core of the Sun is transported to the surface by radiation in the radiation zone and then by convection in the convection zone.
Where and how is energy created in the sun’s interior?
The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun's core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom. During the fusion process, radiant energy is released.
How heat transfers from within the Sun starting in the core and moving outward?
The energy produced through fusion in the core moves outward, first in the form of electromagnetic radiation called photons in the so-called radiative zone. Next, energy moves upward in photon heated solar gas. This type of energy transport is convection.
How is convection used in the energy transfer of the Sun?
When thermal energy radiates from the sun, it heats both the land and ocean, but water has a specific high heat capacity, so it heats up slower than land. This temperature difference creates a convection current, which then manifests as wind.
What two ways is energy transported in the Sun in order from inside out quizlet?
Energy is produced in the core. It enters the radiative zone, where it moves as radiation. As it gets further out from the center, the gas gets less ionized and so more opaque to radiation. In this region the energy moves by convection, with hot gas physically rising through the Sun.
How does energy move through the convection zone of the Sun?
The Solar Interior Energy is generated in the core, the innermost 25%. This energy diffuses outward by radiation (mostly gamma-rays and x-rays) through the radiative zone and by convective fluid flows (boiling motion) through the convection zone, the outermost 30%.
What happens in the interior of sun?
The Sun's central core is plasma with a temperature of around 27 million °C. At such high temperatures hydrogen combines to form helium by nuclear fusion, a process that releases vast amounts of energy. This energy moves outward, towards the outer layers of the Sun.
What are the interior layers that energy travels through from the sun?
The inner layers are the Core, Radiative Zone and Convection Zone. The outer layers are the Photosphere, the Chromosphere, the Transition Region and the Corona. IRIS will focus its investigation on the Chromosphere and Transition Region.
Is the Sun radiation convection or conduction?
Conduction, the collisional transfer of energy between atoms, only occurs between solids (such as a hot pan and your hand), so is not found in the Sun. Convection is the motion of heated material, such as bubbles in boiling water. Radiation is the transfer of energy by electromagnetic waves (light).
What is the order of how energy is transported from the Sun’s core to its surface quizlet?
The energy generated in the core of the Sun is transported to the surface by radiation in the radiation zone and then by convection in the convection zone.
What are the regions of energy transport from the center outward in a solar mass star?
The core is at the center. It the hottest region, where the nuclear fusion reactions that power the Sun occur. Moving outward, next comes the radiative (or radiation) zone. Its name is derived from the way energy is carried outward through this layer, carried by photons as thermal radiation.
What is the Sun’s interior made of?
The energy moves outward through the interior layers, into the sun's atmosphere, and is released into the solar system as heat and light….Abundance of elements.
| Element | Abundance (pct. of total number of atoms) | Abundance (pct. of total mass) |
|---|---|---|
| Hydrogen | 91.2 | 71.0 |
| Helium | 8.7 | 27.1 |
| Oxygen | 0.078 | 0.97 |
| Carbon | 0.043 | 0.40 |

What are the layers of the Sun starting from the center and moving outward?
The inner layers are the Core, Radiative Zone and Convection Zone. The outer layers are the Photosphere, the Chromosphere, the Transition Region and the Corona.
How is energy transported from production to emission at the surface of the Sun?
Radiation is the transfer of energy by electromagnetic waves (light). Only convection and radiation transfer are important in the Sun and the opacity determines which method is used. When the temperature is high and all the atoms are stripped of their electrons, the opacity is low and radiation transfer is dominant.
What is the outermost layer of the Sun’s interior?
the corona The chromosphere may play a role in conducting heat from the interior of the sun to its outermost layer, the corona.
How is energy transferred in the convection zone of the Sun?
In the convection zone, photons are transferred to the photosphere through convection currents. The gases are heated near the radiative zone and are lighter than the gases near the cooler photosphere. The heated gas rises and the cooler gases sink, creating convection currents.
How is energy transported in the convection zone?
Energy is generated in the core, the innermost 25%. This energy diffuses outward by radiation (mostly gamma-rays and x-rays) through the radiative zone and by convective fluid flows (boiling motion) through the convection zone, the outermost 30%.

Which layer of the Sun produces energy?
The Core The Core: 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 helium (He).
