Wulkany understanding

A wulkan is an opening or ruptura in the Earth 's surface the the Earth' s surface through gh which molten rock (magma), wulkan ash, and gases escape. Volcanoes are both constructiva and destructiva: they build new land but can also devastate entire regions. The nature of an eruption - gentle or explosive - depends largely on thee composition of thee magma, especially its silica content and gas pressure.
