What happened to energy in the sun’s convection zone?
Energy from the radiation zone passes into the convection zone the outer layer of the sun's interior. In the convection zone energy is transferred outward mainly by convection currents. Hot gases in the convection zone rise toward the sun's atmosphere while cooler gases sink downward.
What happens during convection in the sun?
Convection in the Sun Hot plasma rises from the core towards the surface, where it cools and sinks back towards the core. This process forms convection cells that we see as solar granules. The lighter color in the granules is the sun's hot plasma that has risen to the surface.
How does energy move through the convection zone?
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 happens in the convective 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 to the energy in the sun’s convection zone quizlet?
What happens to energy in the Sun's convection zone? Energy is produced in the convection zone by nuclear fusion. Energy is transported outward by the rising of hot plasma and sinking of cooler plasma.
What is the role of the convective zone in the sun?
The convection zone is the outer-most layer of the interior. It extends from a depth of 200,000 km up to the visible surface of the Sun. Energy is transported by convection in this region. The surface of the convection zone is where light (photons) is created.
What type of energy is transferred by convection currents?
heat energy Convection. Convection is the transfer of heat energy in a fluid. This type of heating is most commonly seen in the kitchen with a boiling liquid. Air in the atmosphere acts as a fluid.
How does energy move within the sun?
Inside the Sun, conduction is ineffective (the Sun is not solid). 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).
How does energy move in the sun?
The Sun generates energy deep in its core through nuclear fusion that burns Hydrogen into heavier atoms. As the atoms merge, energy is released, and begins the long journey toward the Sun's surface. Along the journey, energy is transferred via two of the the methods of heat transfer: convection and radiative transfer.
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.
How is the energy generated in the Sun quizlet?
The Sun's energy is generated by: fusing hydrogen nuclei into helium within the solar core. Nuclear fusion is the primary source of energy in the universe.
What happens to particles in a convection current as they heat?
Convection is the transfer of thermal energy by particles moving through a fluid. Thermal energy is always transferred from an area with a higher temperature to an area with a lower temperature. Moving particles transfer thermal energy through a fluid by forming convection currents.
Which type of energy is transferred by convection currents quizlet?
During convection, heated particles of a fluid begin to flow, transferring heat energy from one part of the fluid to another. Heat transfer by convection is caused by differences in temperature and density within a fluid.
Is the sun conduction convection?
Conduction, the collisional transfer of energy between atoms, only occurs between solids (such as a hot pan and your hand), so is not found in the Sun. Convection is the motion of heated material, such as bubbles in boiling water. Radiation is the transfer of energy by electromagnetic waves (light).
In which layer of the sun does energy move in convection currents?
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 the convection zone of the sun made of?
plasma The convective zone, like the rest of the Sun, is made up entirely of plasma. A plasma is a 'gas' that conducts electrical currents, just like a wire does. The 'gas' contained in neon light bulbs is a plasma for example.
What happens to the energy in the Sun’s convection zone quizlet?
What happens to energy in the Sun's convection zone? Energy is produced in the convection zone by nuclear fusion. Energy is transported outward by the rising of hot plasma and sinking of cooler plasma.
How does energy produced in the core of the sun reach the surface?
Energy is carried away from the Sun's core by radiative diffusion and convection.
Where in our sun is energy produced and how does the process occur *?
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.
How does the sun provide the energy that drives convection within the atmosphere producing winds?
The sun powers the wind by heating up parts of the earth more than others. Wind is the movement of air. The sun heats the air, and the warm air rises. This rising warm air makes the cooler air from the surrounding areas come in to replace it.
How is energy transferred during convection quizlet?
Convection is the transfer of thermal energy by particles moving through a fluid. Convection works only in liquids and gases (fluids) because their particles can move apart from each other and flow.
How is energy moved through the sun?
Radiation is the transfer of heat energy through space by electromagnetic radiation. Most of the electromagnetic radiation that comes to the earth from the sun is invisible. Only a small portion comes as visible light. Light is made of waves of different frequencies.
Which type of energy is transferred by convection currents?
heat energy Convection is the transfer of heat energy in a fluid. This type of heating is most commonly seen in the kitchen with a boiling liquid. Air in the atmosphere acts as a fluid.
How energy is transferred through each layer of the sun?
In the convection zone, energy is transported by the movement of the plasma or the hydrogen and the helium ions. Plasma churns vigorously, transporting heat energy to the surface of the Sun through convection.
How is energy produced in the sun?
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.
How is energy produced inside the sun?
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.
How does the sun provide energy that drives convection within the atmosphere and oceans?
Page 1. How the sun provides the energy that drives convection within the atmosphere and oceans, producing winds and ocean currents. The heating of the Earth's surface and atmosphere by the sun drives convection within the atmosphere and ocean. This convection produces winds and ocean currents.
Which statement describes how heat is transferred by convection?
Which statement describes how heat is transferred by convection? Air molecules touch the warm ground, heating them up. Sunlight travels through space without the aid of fluids or solids.
What must happen for heat to be transferred by convection?
Thermal energy is transferred from hot places to cold places by convection. Convection occurs when warmer areas of a liquid or gas rise to cooler areas in the liquid or gas. Cooler liquid or gas then takes the place of the warmer areas which have risen higher. This results in a continous circulation pattern.
What is the convection layer of the sun?
The convection zone is the outer-most layer of the interior. It extends from a depth of 200,000 km up to the visible surface of the Sun. Energy is transported by convection in this region. The surface of the convection zone is where light (photons) is created.
