The color temperature of daylight is close to 4300K, which is why we as human beings that see best during the daylight are able to see more vividly with a 4300K HID kit compared to 2300K from halogen bulbs. The light output from a 35W 4300K HID Xenon lamp is about 300% more visible light than a 55W halogen bulb.
Magma originates either from rising plumes of heat at hot spots in the Earth's mantle, where decompression melting takes place as the hot rock nears the surface; or, it originates in the mantle from subduction of oceanic crust, where cold, wet rock speeds melting of the subducting rock and it rises toward the surface.
