Document Summary
Unit 4 global energy balance || unit 1 temperature and radiation. Earth receives energy from the sun (150 million km from the earth) this is our nearest star. Celestial giant furnace, core is extremely hot, near 15million c. In the core, hydrogen nuclei protons collide at such statistically high speeds, that they fuse together to form an alien nuclei. With the formation of a heavy hydrogen atom, as an intermediate step. This thermos-nuclear process generates an enormous amount of energy. This energy gradually makes it way from the core, to the outside surface of the sun. This is called the photosphere sphere of light. Temperatures at the photosphere are much cooler than they are in the interior (approx. The energy transferred to the earth from the sun is radiant energy or radiation. It travels in the form of waves that release energy when they are absorbed by an object.
