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.
Volcanoes form when hot material from below rises and leaks into the crust. This hot material, called magma, comes either from a melt of subducted crustal material, and which is light and buoyant after melting, or it may come from deeper in the interior of a planet and is light and buoyant because it is *very* hot.lumes. Magma consists of remelted material from Earth's crust and fresh material from other regions near the Earth's surface. When magma is erupted onto the surface in the form of lava, it becomes silicate rock.
