What is the layer of the Sun through which energy is transferred away from the core by radiation?

What is the layer of the Sun through which energy is transferred away from the core by radiation?

Unit 4, Lesson 3: The Sun

radiative zone layer of the sun which energy is transferred away from the core by radiation
core very dense center of the sun
nuclear fusion process by which tow or more low-mass atomic nuclei fuse to form another, heavier nucleus.
radiation when energy is transferred as electromagnetic waves

How is energy transferred through each layer of the Sun?

The corona is the outermost layer of the Sun and is the outermost part of its atmosphere. Fusion reactions in the Sun’s core produce energy, which we experience as heat and light. The rest of the Sun is heated by movement of heat energy outward from the core. Light energy from the Sun is emitted from the photosphere.

How does the Sun produce energy?

The sun generates energy in its core in a process called nuclear fusion. During nuclear fusion, the sun’s extremely high pressure and hot temperature cause hydrogen atoms to come apart and their nuclei (the central cores of the atoms) to fuse or combine. Four hydrogen nuclei fuse to become one helium atom.

What is the 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. IRIS will focus its investigation on the Chromosphere and Transition Region.

What is the hottest layer in the Sun’s atmosphere?

the corona
The Transition Region Above it is a region in the solar atmosphere where the temperature changes from 10,000 K (typical of the chromosphere) to nearly a million degrees. The hottest part of the solar atmosphere, which has a temperature of a million degrees or more, is called the corona.

What are the 7 layers of the Sun?

It is composed of seven layers: three inner layers and four outer layers. The inner layers are the core, the radiative zone and the convection zone, while the outer layers are the photosphere, the chromosphere, the transition region and the corona.

Which layer of the Sun is the coolest?

The photosphere
The photosphere, which is outside the core, is the coolest layer. This is as expected, because normally heat passes outwardly from hot to cold. However, the Sun’s outermost atmospheric layer is much hotter than its surface layer!

Does the Sun make a sound?

The sun is not silent; in fact, it has a surprisingly soothing sound. Have you ever listened to the sun? Thanks to data from the European Space Agency (ESA) and NASA’s Solar and Heliospheric Observatory (SOHO), now you can.

Does the sun make a sound?

What is the main source of energy on Earth?

The Sun
The Sun is Earth’s primary source of energy.

What layer of the Sun is the hottest?

Core. The hottest part of the Sun is the core, at 28,080,000°F, on average.

What is corona of Sun?

Definition: Corona is a luminous envelope of plasma that surrounds the Sun and other celestial bodies. It is extended to millions of kilometres into space and is commonly seen during a total solar eclipse. The composition of the corona is the same as the interior of the Sun, mainly made up of hydrogen but ionized form.
