In which layer of the Sun is energy transferred?
Unit 4, Lesson 3: The Sun
A | B |
---|---|
chromosphere | middle layer of the sun’s atmosphere |
photosphere | visible surface of the sun |
convection zone | layer of the sun which energy travels by convection from the radiative zone to the photosphere |
radiative zone | layer of the sun which energy is transferred away from the core by radiation |
In which layer of the Sun do bubbling gases rise and fall keeping energy constantly moving to the surface?
Particles of light called photons carry this energy through a spherical shell called the radiative zone to the top layer of the solar interior, the convection zone. There, hot plasmas rise and fall like the ooze in a lava lamp, which transfers energy to the sun’s surface, called the photosphere.
What happens in the corona layer of the Sun?
The corona is in the outer layer of the Sun’s atmosphere—far from its surface. Yet the corona is hundreds of times hotter than the Sun’s surface. In the corona, the heat bombs explode and release their energy as heat. But astronomers think that this is only one of many ways in which the corona is heated.
What are the layers of the Sun and what do they do?
The main part of the Sun has three layers: the core, radiative zone, and convection zone. The Sun’s atmosphere also has three layers: the photosphere, the chromosphere, and the corona. Nuclear fusion of hydrogen in the core of the Sun produces tremendous amounts of energy that radiate out from the Sun.
How energy moves through the Sun?
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.
Which layer of the Sun moves heat energy to the convective layer?
Radiative Zone
The Radiative Zone – Energy moves slowly outward, taking more than 170,000 years to radiate through this layer of the Sun. The Convection Zone – Energy continues to move toward the surface through convection currents of the heated and cooled gas.
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.
What happens in the chromosphere of the sun?
NASA/Marshall Solar Physics. The chromosphere is an irregular layer above the photosphere where the temperature rises from 6000°C to about 20,000°C. At these higher temperatures hydrogen emits light that gives off a reddish color (H-alpha emission).
What is the chromosphere layer of the Sun?
The lower region of the Sun’s atmosphere is called the chromosphere. Its name comes from the Greek root chroma (meaning color), for it appears bright red when viewed during a solar eclipse. The chromosphere extends for about 2,000 kilometers (1,200 miles) above the visible surface of the Sun.
Is there a layer of the sun called corona?
The corona is the outer atmosphere of the Sun. It extends many thousands of kilometers (miles) above the visible “surface” of the Sun, gradually transforming into the solar wind that flows outward through our solar system. The material in the corona is an extremely hot but very tenuous plasma.
What are the 3 main layers 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.
Whats the second layer of the Sun?
radiative zone
The radiative zone is the second inner layer of the Sun. It sits outside of the core, and it holds its extremely high temperature. The zone itself has a temperature of around 7 million degrees Fahrenheit.
What is the path of energy through the Sun?
Energy from the core seeps very slowly through the radiative zone toward the sun’s surface. It can take 100,000 years for a ray of light to pass through this thick, dense layer. Core Core Inside the dense, hot core of the sun, particles of a gas called hydrogen merge together to create another gas, called helium.
How does heat move from the Sun’s core to the surface?
Vast bubbles of hot gas rise up through this zone to the surface, where they cool and sink again. This process allows heat to move from the sun’s heart to its outer surface. This layer is made of hydrogen gas squeezed very tightly together. Energy from the core seeps very slowly through the radiative zone toward the sun’s surface.
How do photons travel through the atmosphere of a star?
Photons are bundles of electromagnetic radiation and the radiative diffusion carrying the Sun’s energy from the core occurs in the radiative zone, the area inside a star, like the Sun, where energy flows outwards as photons. As the energy flows outwards, it encounters cooler, opaque gas, which isn’t very transparent to radiation.
How much energy does the Sun release in a second?
Every second, the sun releases 1 million times more energy than everyone on Earth uses in a year. The chromosphere is the lowest layer of the sun’s atmosphere. It is orange-red in color, and about 1,200 miles (2,000km) thick.
