The light output from a 35W 4300K HID Xenon lamp is about 300% more visible light than a 55W halogen bulb. The Xenon HID kit will also consume much less power from your vehicles electrical system and generate much less heat during operation.
Deep inside Earth, between the molten iron core and the thin crust at the surface, there is a solid body of rock called the mantle. When rock from the mantle melts, moves to the surface through the crust, and releases pent-up gases, volcanoes erupt. Extremely high temperature and pressure cause the rock to melt and become liquid rock or magma.
Volcanoes can form in three geologic settings, all of which result in the melting of rock in the upper part of the mantle. The rock in the mantle is very hot but is kept solid under immense pressure. Some volcanoes form at divergent boundaries where two of Earth's tectonic plates pull apart. The crust is thin at these boundaries, reducing pressure on the mantle, allowing some melting to occur, forming molten rock called magma. This rises to the surface, forming volcanoes.
