In which region of the sun does energy move through circulating currents of gasses?
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 is convection zone in the sun quizlet?
Convective zone. The region of the sun's interior that is between the radiative zone and the photosphere and which energy is carried upward by convection. photosphere. the visible surface of the sun. corona.
Which regions make up the sun’s atmosphere quizlet?
the core, the radiation zone, and the convection zone.
Which zone of the sun moves energy through radiation quizlet?
The radiative zone is the layer of the sun through which energy is transffered away from the core from radiation.
What is convection zone sun?
The convection zone is the outer-most layer of the solar interior. It extends from a depth of about 200,000 km right up to the visible surface. At the base of the convection zone the temperature is about 2,000,000° C.
What happens in the convection zone of the sun?
In the convection zone, photons are transferred to the photosphere through convection currents. The gases are heated near the radiative zone and are lighter than the gases near the cooler photosphere. The heated gas rises and the cooler gases sink, creating convection currents.
What is the radiative zone of the Sun?
The radiative zone is a thick layer of highly ionized, very dense gases which are under constant bombardment by the gamma rays from the core. It is about 75% hydrogen and 24% helium. Because most of the atoms here lack electrons, they can't absorb photons for convection to the surface. Most photons just bounce around.

What happens in the convection zone of the Sun?
In the convection zone, photons are transferred to the photosphere through convection currents. The gases are heated near the radiative zone and are lighter than the gases near the cooler photosphere. The heated gas rises and the cooler gases sink, creating convection currents.
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 the corona of the Sun?
The corona is the outermost layer of the Sun's atmosphere where strong magnetic fields bind plasma and prevent turbulent solar winds from escape. The Alfvén point is when solar winds exceed a critical speed and can break free of the corona and the Sun's magnetic fields.
What are the regions of the Sun?
The sun is made up of six layers: core, radiative zone, convective zone, photosphere, chromosphere, and corona.
What occurs 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.
What happens in the transition zone of the Sun?
Transition Region – The transition region is a very narrow (60 miles / 100 km) layer between the chromosphere and the corona where the temperature rises abruptly from about 8000 to about 500,000 K (14,000 to 900,000 degrees F, 7700 to 500,000 degrees C).
What does the radiative zone do?
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 convection zone of the Sun?
The convection zone is the outer-most layer of the solar interior. It extends from a depth of about 200,000 km right up to the visible surface. At the base of the convection zone the temperature is about 2,000,000° C.
What are sunspots?
Sunspots are areas where the magnetic field is about 2,500 times stronger than Earth's, much higher than anywhere else on the Sun. Because of the strong magnetic field, the magnetic pressure increases while the surrounding atmospheric pressure decreases.
Why is corona so hot?
Because the coronal material is so thin and tenuous, only a tiny portion of all the sound energy in the photosphere needs to bleed up into the corona and be absorbed in order to heat it to the observed temperatures.
What is convective zone of the Sun?
The convection zone is the outer-most layer of the solar interior. It extends from a depth of about 200,000 km right up to the visible surface. At the base of the convection zone the temperature is about 2,000,000° C.
What is the radiation 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 is a 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.

What is solar wind made of?
The solar wind is created by the outward expansion of plasma (a collection of charged particles) from the Sun's corona (outermost atmosphere). This plasma is continually heated to the point that the Sun's gravity can't hold it down. It then travels along the Sun's magnetic field lines that extend radially outward.
Why is the Sun hot NASA?
This is because the Sun's surface isn't solid like Earth's. Instead, the Sun is made of super-hot, electrically charged gas called plasma. This plasma rotates at different speeds on different parts of the Sun. At its equator, the Sun completes one rotation in 25 Earth days.
What is solar wind energy?
The solar wind is a hot and fast flow of magnetized gas that streams away from the sun's upper atmosphere. It is made of hydrogen and helium ions with a sprinkling of heavier elements. Researchers liken it to the steam from a pot of water boiling on a stove; the sun is literally boiling itself away.
How old is the Earth?
4.543 billion yearsEarth / Age
Is space actually cold?
Though sci-fi movies would have us believe that space is incredibly cold — even freezing — space itself isn't exactly cold. In fact, it doesn't actually have a temperature at all. Temperature is a measurement of the speed at which particles are moving, and heat is how much energy the particles of an object have.
What is wind energy called?
Wind power or wind energy describes the process by which the wind is used to generate mechanical power or electricity. Wind turbines convert the kinetic energy in the wind into mechanical power.
How is wind energy from the sun?
Wind energy is actually a byproduct of the sun. The sun's uneven heating of the atmosphere, the earth's irregular surfaces (mountains and valleys), and the planet's revolution around the sun all combine to create wind.
Who created Earth?
Formation. When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle, and a solid crust.
