How does energy from the sun move from the core to the photosphere?

Energy from the core travels by radiation through the radiative zone, then by convection through the convection zone.


What is the process in which sun rays reach the Earth?

RadiationHeat can't travel through a vacuum, directly, so the sun emits energy as light. The earth receives about a two billionth of the sunlight emitted, but the light is converted to heat and other energy forms.


Which form of energy is unable to travel through a vacuum?

In the first chapter of his book, Quantum Theory, David Bohm discusses potential energy transfers from empty space to, within, and out of blackbody radiators, where he develops a formula for the total energy in empty space to be the sum of contributions by electric and magnetic fields integrated over all space available to the respective fields.In the last chapter of the book, Bohm discusses the necessity for both small scale and large scale potentials to interact (quantum with classical), in order "for a specific potentiality to be realized irrevocably at the expense of all other potentialities."Thus, in empty space, energy transfers would be limited to changes in energy potentials. In theory, particle/anti-particle pairs can be created from vacuum energy, and the particle-pair either recombines and annihilates; or one of the pair can transfer into a black hole, while the other waves along its merry way.a: pay attention to THE WORD THEORY


What type of energy do stars give off?

The primary form of radiation coming from the sun is electromagnetic radiation, in less technical terms Light. Light of all types, radio, microwave, infrared, visible, ultraviolet, x-ray, gammaray As alpha and beta radiation are helium nuclei & electrons, those two stream off the sun in the form of solar wind, but aren't the primary form of "radiation"


Why does the temperature change when you move away from the sun?

Temperature of what? Temperature is a "property" of material. Farther away from the sun, the heat (radiation) has spread out over such a wider area that the amount of energy per square foot available to heat anything gets smaller and smaller. Or do you just mean "when you step into a shadow"? Then you are not receiving direct radiation from the sun at all.
