How does energy move through the radiation zone?

How does energy move through the radiation zone?

A radiation zone, or radiative region is a layer of a star’s interior where energy is primarily transported toward the exterior by means of radiative diffusion and thermal conduction, rather than by convection. Energy travels through the radiation zone in the form of electromagnetic radiation as photons.

How does energy pass through the convection zone?

In the convection zone, energy is transported by the movement of the plasma or the hydrogen and the helium ions. Plasma churns vigorously, transporting heat energy to the surface of the Sun through convection.

What happens to the energy after it passes through the radiative and convective zones?

By the time the photons enter the convective zone, they have spent almost fifty million years in transit. In the convective cells, gas absorbs energy from the radiative zone. This energy heats it, and it rises to the next layer, the photosphere, where it dumps its energy off.

What happens in the convection zone?

A region of turbulent plasma between a star’s core and its visible photosphere at the surface, through which energy is transferred by convection. In the convection zone, hot plasma rises, cools as it nears the surface, and falls to be heated and rise again.

How does the energy move from the center of the Sun to the Earth?

Energy is transferred from the sun to Earth via electromagnetic waves, or radiation. Most of the energy that passes through the upper atmosphere and reaches Earth’s surface is in two forms, visible and infrared light. This transfer of energy can take place by three processes: radiation, conduction, and convection.

What happens to energy in the convection zone of the sun Group of answer choices?

What happens to energy in the Sun’s convection zone? Energy is transported outward by the rising of hot plasma and sinking of cooler plasma. Order the interior layers of the Sun from the hottest to the coldest.

What happens in the radiative zone?

In the radiative zone, energy generated by nuclear fusion in the core moves outward as electromagnetic radiation. In other words, the energy is conveyed by photons. Many other stars also have radiative zones. The Sun’s radiative zone extends from the core outward to about 70% of the Sun’s radius.

What happens to energy in the radiative zone of the sun?

Just outside the Inner Core of the sun at a distance approximately 0.25 to 0.7 solar radii lies the Radiative Zone. This zone radiates energy through the process of photon emission and capture by the hydrogen and helium ions.

What happens to energy in the convection zone of the Sun Group of answer choices?

How does the heat from the earth’s core and radiation from the Sun is transferred to the surface of the earth?

How is energy transported through the Sun?

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 generated in the radiative zone?

The Radiative Zone. The radiative zone is characterized by the method of energy transport – radiation. The energy generated in the core is carried by light (photons) that bounces from particle to particle through the radiative zone.

How is energy transported from the center of a star?

Energy is transported by three mechanisms Radiation- photons carry energy away from the star’s center Convection- cells of hot gas move up, cells of cool gas move down Conduction- collisions between electrons can move energy outwards In most stars, conduction is not important.

Where does the radiative zone extend from the core?

The radiative zone extends outward from the outer edge of the core to the interface layer or tachocline at the base of the convection zone (from 25% of the distance to the surface to 70% of that distance).

What is the temperature at the base of the convection zone?

At the base of the convection zone the temperature is about 2,000,000° C. This is “cool” enough for the heavier ions (such as carbon, nitrogen, oxygen, calcium, and iron) to hold onto some of their electrons. This makes the material more opaque so that it is harder for radiation to get through.
