什么是火山火山是地面的通气口,它可以发生在陆地或水下。由于地表以下的压力,气体和灰尘伴随着岩浆一起从这些通气口喷出,从而造成了各式各样的地质特征。最主要和最壮观的生成物就是火山本身,她是由从火山口喷出的岩屑堆积而成。火山一词源于第勒尼安海的火山岛,位于意大利两西里岛顶部以北,这里有座火山,现在正值休眠(最近一次喷发是在1890年),但在古代经常喷发,这使罗马人相信:这是通向地下火神伍尔坎辖区的大门。
What is a Volcano Volcano is the ground vent, which can occur on land or underwater. Due to the pressure below the earth’s surface, gas and dust emanate from the vents along with the magma, resulting in a wide range of geological features. The main and most spectacular product is the volcano itself, she is from the volcano eruption of debris deposited. The word Volcano originates from the volcanic island of the Tyrrhenian Sea, north of the top of the island of Two Sicilies in Italy, with a volcano now dormant (most recently erupted in 1890) but often erupted in ancient times, People believe: This is the gateway to the underground Wulfan Wulcan area.
