What is the layer between the core and the convective zone?

What is the layer between the core and the convective zone?

The Sun’s radiative zone is the section of the solar interior between the innermost core and the outer convective 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.

What is the inner layer of the Sun next to the core called?

Radiative Zone
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.

What layer of the Sun has convection?

Convection Zone of the Sun Above the radiative zone is the convection zone, which spans the outer 30% of the Sun’s interior. The convection zone begins when the temperatures are low enough that radiation isn’t a dominant form of heat transfer.

What does the chromosphere of the Sun do?

The layer above the photosphere is the chromosphere. The chromosphere emits a reddish glow as super-heated hydrogen burns off. But the red rim can only be seen during a total solar eclipse. 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 between the core and the convective zone of the Sun?

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 is the core of the sun made up of?

hydrogen
The core of the Sun is home to billions and billions of atoms of hydrogen, the lightest element in the universe. The immense pressure and heat pushes these atoms so close to one another that they squish together to create new, heavier atoms. This is called nuclear fusion.

Why is the convection zone called convection?

We call them convection cells because they are due to convection, the physical mechanisms responsible for the boiling water. The bright regions correspond to hot rising material, whereas the dark lanes are the location where the colder material falls down into the Sun.

Which layer of the Sun is where fusion occurs?

core
The Sun’s interior domain includes the core, the radiative layer, and the convective layer (Figure 2–1). The core is the source of the Sun’s energy, the site of thermonuclear fusion.

What is the chromosphere made up of?

The chromosphere is mainly made of hydrogen and helium plasma, which is ionized to produce red visible light, as seen during an eclipse.

What is the chromosphere of the Sun composed of?

Why does the chromosphere shine so brightly in the color red? Composed mostly of hydrogen, under these temperature conditions, the most common way that hydrogen gases shine is through the emission of a particular spectral line called hydrogen-alpha or Ha at a wavelength of 656.3 nanometers (6563 Angstroms).

Which layer is the outermost layer of the Sun What does this layer do?

corona
The sun’s chromosphere But the red rim can only be seen during a total solar eclipse. At other times, light from the chromosphere is usually too weak to be seen against the brighter photosphere. The chromosphere may play a role in conducting heat from the interior of the sun to its outermost layer, the corona.

Which is the outermost layer of 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.

How does the convection zone of the Sun work?

The convection zone is not dense enough to transmit energy. Instead, this layer moves heat to the surface of the sun where it cools and drops back into the convection zone where it reheats.

Which is cooler the core or the convection layer?

The temperature at this layer is cooler than the core at 7 million degrees Fahrenheit causing thermal radiation. This layer has 60 percent mass and 90 percent volume. The convection zone is not dense enough to transmit energy.

What’s the temperature of the core of the Sun?

The heat from the core is 15 million degrees Kelvin which translates to roughly 27 million degrees Fahrenheit. Kelvin is a temperature scale that picks up where the Celsius degree ends. The core is comprised of a radiative layer that emits radiation and a convective layer that transfers heat.
