What is the dominant mechanism by which energy is transported through the inner regions of the Sun Group of answer choices?
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.
How is energy transported outward in the Sun’s interior?
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 process provides the power for the Sun?
The sun is powered by nuclear fusion, a process through which hydrogen is converted into helium, emitting large amounts of energy.
What mechanism does solar energy reach the Sun’s photosphere from the layer just underneath it?
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. This top layer is called the photosphere.
How is energy transported from the core to the surface of the Sun by radiation and by convection?
Explanation. Energy is transferred through electromagnetic radiation in the radiation zone. In this process, the particles repeatedly absorb and re-emit the waves until they reach the outermost part of the radiative zone. On the other hand, the energy is transferred through convection currents in the convection zone.
How does energy from the Sun travel to Earth through radiation through convection through conduction through the movement of particles?
During the day, sunlight heats the ground, which in turn heats the air directly above it via conduction. At night, the ground cools and the heat flows from the warmer air directly above to the cooler ground via conduction.
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 does energy travel through the layers of the Sun?
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 energy from the sun called?
Solar radiation, often called the solar resource or just sunlight, is a general term for the electromagnetic radiation emitted by the sun. Solar radiation can be captured and turned into useful forms of energy, such as heat and electricity, using a variety of technologies.
What process provides the power for the sun quizlet?
Which process provides power for the Sun? fusion of hydrogen into helium.
What two energy transport mechanisms in order from the surface to the outside the core are found in the Sun?
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.

How is energy transported through the radiation zone of the Sun?
The radiative zone is characterized by the method of energy transport – radiation. The energy generated in the core is carried by light (photons) that bounces from particle to particle through the radiative zone.
How is energy transferred from the core of the Sun to its outer layers?
Energy is radiated out from the core first, then carried to the outer layers by convection. Energy is carried out from the core by convection first, then radiated to the outer layers.
How is energy transferred through conduction and convection?
In CONVECTION, heat energy is carried by the movement of particles of matter. In CONDUCTION, heat is transferred by particles vibrating. In RADIATION, heat is carried directly by electromagnetic waves. When a hot object touches a cool object, heat moves from the hot one to the cool one.
How is heat transferred by conduction convection and radiation?
Thermodynamics is the study of heat transfer and the changes related to it. Conduction is nothing but the heat transfer from the hotter part to the colder one. Convection is the heat transfer by up and down motion of the fluid. Radiation occurs when heat travels through empty space.
How is energy transferred from the core of the sun to its surface?
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.
How is energy transported from the core to the surface of the sun by radiation and by convection?
Explanation. Energy is transferred through electromagnetic radiation in the radiation zone. In this process, the particles repeatedly absorb and re-emit the waves until they reach the outermost part of the radiative zone. On the other hand, the energy is transferred through convection currents in the convection zone.
What is the energy from the internal heat of the Earth called?
Geothermal energy is heat that is generated within the Earth. (Geo means “earth,” and thermal means “heat” in Greek.) It is a renewable resource that can be harvested for human use. About 2,900 kilometers (1,800 miles) below the Earth's crust, or surface, is the hottest part of our planet: the core.
Which type of energy transfer is responsible for the movement of magma in Earth’s interior?
Convection currents in the magma drive plate tectonics. Heat generated from the radioactive decay of elements deep in the interior of the Earth creates magma (molten rock) in the aesthenosphere. The aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the Earth that extends to 2900 km.
What process provides the energy to maintain the Sun’s radiative output?
This process is known as nuclear fusion, and it results in the formation of heavier elements as well as the release of energy in the form of gamma ray photons. The energy output of the Sun's core is so large that it would shine about 1013 times brighter than the solar surface if we could “see” it.
What is the solar wind quizlet?
A stream of electrically charged particles that flow outward from the Sun's corona.
What two energy transport mechanisms in order from outside the core to the surface are found in the Sun quizlet?
The energy generated in the core of the Sun is transported to the surface by radiation in the radiation zone and then by convection in the convection zone.
How does the energy transport from the core of the Sun to the photosphere?
By 30% of the radius, fusion has stopped almost entirely. The rest of the sun is heated by the energy that is transferred from the core through the successive layers, eventually reaching the solar photosphere and escaping into space as sunlight or the kinetic energy of particles.
How energy is transported from the core to the surface of the Sun by radiation and by convection?
Explanation. Energy is transferred through electromagnetic radiation in the radiation zone. In this process, the particles repeatedly absorb and re-emit the waves until they reach the outermost part of the radiative zone. On the other hand, the energy is transferred through convection currents in the convection zone.
How is energy transferred in 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 transferred in conduction?
Conduction is the transfer of energy from one molecule to another by direct contact. This transfer occurs when molecules hit against each other, similar to a game of pool where one moving ball strikes another, causing the second to move.
How is heat transferred from the Sun to Earth?
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.
How is heat energy transferred?
Heat can be transferred in three ways: by conduction, by convection, and by radiation.
What kind of process by which heat energy is transmitted?
Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules.
