An outcrop view of a metaconglomerate: 1  Shale is a sedimentary term. 2  Slate refers to a fine-grained, low-grade metasedimentary rock in which bedding is typically still visible: 3  Schist refers to a medium-to high-grade, medium-to coarse-grained metamorphic rock of any composition that has a fabric.
Total solar irradiance (TSI), is a measure of the solar radiative power per unit area normal to the rays, incident on the Earth's upper atmosphere. The solar constant is a conventional measure of mean TSI at a distance of one Astronomical Unit (AU).
As a result, the Sun does not emit gamma rays from this process, but it does emit gamma rays from solar flares. The Sun also emits X-rays, ultraviolet, visible light, infrared, and even radio waves; the only direct signature of the nuclear process is the emission of neutrinos.
