what two energy transport mechanisms in order from

What two ways is energy transported in the Sun in order from inside out?

visible light. Energy moves through the sun in two main ways: by radiation and by convection. As energy moves outward from the sun’s core, it first enters the radiation zone. The radiation zone is a region of highly compressed gas.

What mechanism does solar energy reach the Sun’s photosphere from the layer just underneath it?

In this region the energy moves by convection, with hot gas physically rising through the Sun. When it reaches the surface, or photosphere, the low density makes the Sun transparent, and the energy escapes as light.

What are the main constituents of the solar wind which travel faster?

What are the main constituents of the solar wind? Which travel faster? The lower mass electrons move much faster than the protons that lag behind. Why is it hard to observe the chromosphere?

Which energy transport mechanism produces the granulation seen on the photosphere?

The granulation is produced by the convection (boiling) of the Sun’s gases.

How is energy transported through the interior of 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).

What is the order of how energy is transported after leaving the Sun’s core?

The energy generated in the core is transported toward the surface by radiation until it reaches a point about 70% of the distance from the center to the surface. At this point, convection begins, and energy is transported the rest of the way, primarily by rising columns of hot gas.

What is the correct order of the Sun’s layers from the inside out?

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 are the three layers of the Sun’s atmosphere in order of increasing distance from the surface?

In order of increasing distance from the center of the Sun, they are the photosphere, with a temperature that ranges from 4500 K to about 6800 K; the chromosphere, with a typical temperature of 10⁴ K; the transition region, a zone that may be only a few kilometers thick, where the temperature increases rapidly from 10⁴ …

What layer of the Sun is the chromosphere?

photosphere
The chromosphere is above the photosphere, the visible “surface” of the Sun. It lies below the solar corona, the Sun’s upper atmosphere, which extends many thousands of kilometers above the chromosphere into space. The plasma (electrically charged gas) in the chromosphere has a very low density.

Which 2 elements make up the sun almost in entirety?

Our Sun consists almost entirely of the elements hydrogen and helium. Because the Sun is not solid, it does not have a defined outer boundary.

What elements are in the solar wind?

The composition of the solar wind is a mixture of materials found in the solar plasma, composed of ionized hydrogen (electrons and protons) with an 8% component of helium (alpha particles) and trace amounts of heavy ions and atomic nuclei: C, N, O, Ne, Mg, Si, S, and Fe ripped apart by heating of the Sun’s outer …

What is the solar wind made up of?

The solar wind is a stream of energetic particles ejected by the Sun. These include electrons and protons from hydrogen, along with atomic nuclei like helium, otherwise known as alpha particles. There are also traces of ‘heavy ions’ and atomic nuclei of carbon, nitrogen, oxygen, neon and magnesium.

Which processes transfer energy from the core to the photosphere?

How is the energy transferred to the sun´s surface? by the processes of radiation and convection.

Which is the first step in the fusion process?

The first step of the Hydrogen fusion process: a nucleus of Deuterium (2H) is formed from two protons with the emission of an antielectron and a neutrino. The basic Hydrogen fusion cycle involves four Hydrogen nuclei (protons) and two electrons and yields a Helium nucleus, two neutrinos and six photons.

How is energy moving in the convection zone?

In this region, energy is transported by radiation (you have radiation around the core of a nuclear central, around a nuclear explosion,…). … Energy is transported by convection in this region. The surface of the convection zone is where light (photons) is created.

Where and how is energy created in the sun’s interior starting from the center what are the interior layers that this energy travels through?

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.

How is energy transferred from the core of the sun to its outer layers?

How is energy transferred from the core of the Sun to its outer layers? Energy radiates outward from the core as visible light. … Energy is radiated out from the core first, then carried to the outer layers by convection.

What type of electromagnetic energy is the Sun’s heat energy?

All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays. Radiation is one way to transfer heat.

What is the process that carries the Sun’s energy the rest of the way to the Sun’s surface?

What is the process that carries the Sun’s energy the rest of the way to the Sun’s surface? What carries the energy? The process is convection. The energy is carried by moving volumes of gas.

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

Unit 4, Lesson 3: The Sun

A	B
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.

What is the layer of the Sun’s interior where energy is transferred mainly by electromagnetic radiation?

The radiation zone

The radiation zone is a region of very tightly packed gas where energy is transferred mainly in the form of electromagnetic radiation. The convection zone is the outermost layer of the sun’s interior.

Where does the energy of our sun come from?

Solar energy is created by nuclear fusion that takes place in the sun. Fusion occurs when protons of hydrogen atoms violently collide in the sun’s core and fuse to create a helium atom. This process, known as a PP (proton-proton) chain reaction, emits an enormous amount of energy.

What are the three layers of the sun’s atmosphere in order of increasing distance from the surface quizlet?

Rank the following layers of the solar atmosphere in order from the outermost to the innermost: chromosphere, corona, photosphere.

Which layer of the sun produces energy?

The core

The core is the only region in the Sun that produces an appreciable amount of thermal energy through fusion; 99% of the power is generated within 24% of the Sun’s radius, and by 30% of the radius, fusion has stopped nearly entirely.

What are the 3 layers of the sun’s atmosphere?

The sun’s atmosphere is made up of several layers, mainly the photosphere, the chromosphere and the corona.

What is photosphere chromosphere and corona?

The Sun – our central star

Beginning from the outside, they are: the corona – the outermost, hot shell of the atmosphere. the chromosphere – a transparent layer between the corona and the photosphere. the photosphere – the visible “surface” of the Sun.

What is the chromosphere made 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 eruption of gases from the chromosphere?

Solar flares are sporadic local eruptions of the chromosphere. They develop suddenly and rapidly, in minutes, and cover a relatively small region of the solar surface. Initially they manifest themselves by a localized sudden brightening. The duration of a solar flare ranges from about 20 minutes to as much as 3 hours.

How does energy makes its way from the nuclear core of the sun to its atmosphere?

Energy is created in the core of the Sun by nuclear fusion which releases energy that moves by radiation through the radiative zone. After that, this energy moves through the convection zone by rising of hot gas and sinking of cool gas.

Is Sun solid liquid or gas?

The Sun is our nearest star. It is, as all stars are, a hot ball of gas made up mostly of Hydrogen. The Sun is so hot that most of the gas is actually plasma, the fourth state of matter. The first state is a solid and it is the coldest state of matter.

What energy travels through the radiative 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.

What is plasma from the sun?

“Most of the atoms in the Sun are ionized. This is particularly true in the hot, dense interior, where essentially all the hydrogen and helium atoms are completely ionized. Such a highly ionized gas is called a plasma.

What are the main constituents of the solar wind which travel faster?
