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.
A volcano is a hollow vent in the Earth's surface, through which hot, molten rock, called magma, along with some gases and hot ash, oozes out from the Earth's interior. Magma erupting from a volcano is called lava.This magma is stored in the interior of the Earth in a sort of a large reservoir known as magma chamber.It is in this chamber that the formation of magma takes place by continuous melting of solid rock.Owing to this, the temperature of the magma chamber is immensely high.agma erupting from a volcano is called lava.
