In most volcanoes, the crater is situated at the top of a mountain formed from the erupted volcanic deposits such as lava flows and tephra. Volcanoes that terminate in such a summit crater are usually of a conical form. Other volcanic craters may be found on the flanks of volcanoes, and these are commonly referred to as flank craters. Some volcanic craters may fill either fully or partial… WebMany of the features we see gracing the Moon’s surface are ‘impact craters’ formed when impactors smashed into the lunar surface. The resulting explosion and excavation of material at the impacted site creates piles of rock (called ejecta) around the circular hole as well as bright streaks of target material (called rays) thrown for great distances.
