WebA meteorite impact occurs when a rocky, metallic (typically iron), or icy body that had been orbiting the Sun passes through the atmosphere to hit the Earth’s surface. In contrast meteors are similar objects that are sufficiently small that they are completely vaporized or burn up in the atmosphere, and do not collide with the Earth’s surface. WebVolcanic craters may have a cone or flanks associated with the crater. There may also be flows present. Impact craters may have central peaks, ejecta, raised rims and floors that are lower in elevation than the surrounding terrain that can distinguish them from volcanic craters. During an impact event, the rocks that are impacted are shocked. 2. lithonia lighting olsr
