How does energy from the sun move from the core to the photosphere?
Energy is generated in the core of the sun through nuclear fusion where hydrogen atoms are converted into helium. This energy then moves through the radiative zone via photons, which are energy particles that bounce around and slowly make their way to the photosphere. The energy eventually reaches the photosphere where it is released as sunlight.
What is the definition of Radiative zone?
The radiation zone or radiative zone is a layer of a star's interior where energy is primarily transported toward the exterior by means of radiative diffusion, rather than by convection.[1] Energy travels through the radiation zone in the form of electromagnetic radiation as photons. Within the Sun, the radiation zone is located in the intermediate zone between the solar core at .2 of the Sun's radius and the outer convection zone at .71 of the Sun's radius.[1]Matter in a radiation zone is so dense that photons can travel only a short distance before they are absorbed or scattered by another particle, gradually shifting to longer wavelength as they do so. For this reason, it takes an average of 171,000 years for gamma rays from the core of the Sun to leave the radiation zone. Over this range, the temperature of the plasma drops from 15 million K near the core down to 1.5 million K at the base of the convection zone.[2]Within a radiative zone, the temperature gradient-the change in temperature (T) as a function of radius (r)-is given by:
How big is the sun's radiation zone?
The radiation zone is the "middle part" of the interior of the Sun. It is adjacent to the core. In this zone, energy travels between the atoms as photons of gamma radiation. Above the radiative zone is the convective zone. Scientists estimate that core energy takes as long as 170,000 years to travel through the dense matter of the radiative zone.According to NASA, the Sun's radiative zone begins about 108,125 miles from the center of the Sun and ends about 302,750 miles from the center of the sun. So the radiative zone makes up 32 percent of the Sun's volume and 48 percent of its mass.The exterior of the Sun, where radiation again occurs, is called the photosphere. In some larger stars, the outer layer is radiative and is substantially thicker.
What do you call a space rock while it is coming through the Earth's atmosphere?
A space rock that is entering Earth's atmosphere is called a meteoroid. As it travels through the atmosphere and begins to heat up and produce bright light, it is then referred to as a meteor or shooting star.
Light or warmth travels first?
Light travels faster than warmth. Light travels at a speed of approximately 299,792 kilometers per second in a vacuum, whereas warmth (or heat) is the transfer of energy from a warmer object to a cooler one, which occurs at a slower pace through conduction, convection, or radiation.
What are the three ways in which energy travels in the atmosphere?
Energy travels in the atmosphere through conduction, convection, and radiation. Conduction is the transfer of heat through direct contact, convection involves the movement of air masses transferring heat vertically, and radiation is the transfer of energy through electromagnetic waves.
The light from polaris travels through space in the form of what energy?
Radiative
When heat travels in a vacuum to heat another source this is known as?
Radiative heat transfer, or simply: radiation. As opposed to conduction and convection.
What does the transfer of energy in the radiative zone differ from the transfer Convective zone?
In the radiative zone of a star, energy is transferred through electromagnetic radiation (photons) as it travels from the core to the convective zone. In contrast, in the convective zone, energy is transferred by the physical movement of hot gas or plasma through convection currents.
How does energy from the sun move from the core to the photosphere?
Energy is generated in the core of the sun through nuclear fusion where hydrogen atoms are converted into helium. This energy then moves through the radiative zone via photons, which are energy particles that bounce around and slowly make their way to the photosphere. The energy eventually reaches the photosphere where it is released as sunlight.
Light energy travels in the form of?
They travels in the form of waves and are filtered through the Earth's atmosphere.
Why cant you get energy from the sun through convection?
Convection travels through matter. It won't travel through empty space.Convection travels through matter. It won't travel through empty space.Convection travels through matter. It won't travel through empty space.Convection travels through matter. It won't travel through empty space.
How is heat transferred within the earth's atmosphere?
Heat is transferred within the Earth's atmosphere through conduction, convection, and radiation. Conduction occurs through direct contact between molecules, convection involves the movement of air masses due to differences in temperature and pressure, and radiation involves heat being emitted and absorbed by the Earth's surface and atmosphere.
How energy moves through radiation zone and the convection zone?
The convective zone,energy is transferred much faster that it is in the radiative zone.
What type of energy is travels through waves?
radiation and convection currents
What kind of heat transfer is represented by the letter B What happens to some of the energy from this process as it travels through the troposphere?
The letter B represents convection, which is heat transfer through the movement of fluids. As the energy from convection travels through the troposphere, some of it is radiated back into space in the form of infrared radiation, while the rest continues to contribute to the heating of the Earth's surface and lower atmosphere.
Does heat travel through a liquid by conduction?
Yes, but more travels through liquids by convection.
