  • 說一說火山

    2018-12-26作者:徐爍礫推薦訪問:說明文 小學生作文
    火山,大家熟悉的不能再熟悉的一個詞。可是,你對火山有多么了解么?咳咳(清清嗓子),就讓我來為大家講一件火山的小知識吧!

    火山,分為死火山、活火山和休眠火山。死火山,指的是那些不在噴發的火山。活火山,指的是那些還會噴發的火山。而休眠火山,是指那些正在“睡覺”的火山,也就是還會噴發的火山。現在科學家發現地球上已經有3500座火山了!

    火山噴發了怎么辦?別急,別急,我來教你一些逃生的方法。火山噴發時,要帶上頭盔或口罩,避免吸入火山噴發時所產生的毒煙毒氣。巖漿流了過來怎么辦呢?迅速逃跑,往高山上逃跑,盡量迅速逃離巖漿流的范圍內。最可怕的是火山泥流,很多人都葬身在火山泥流中。順便插幾句,阿羅梅爾城的人就死于火山泥流。火山泥流的黏性強大,溫度高,搬移性很強,比泥石流、滑坡還厲害!迅速逃離,盡量跑到比火山泥流還要高的山頂上。

    火山是怎么爆發的呢?由于地殼的運動,巖石層里的巖石隨著巖漿動。當有擠壓力的時候,巖漿便從火山口涌出來,就形成了火山爆發。

    今天的火山小知識滿意嗎?下次灰塵——“自然界的流浪漢”不見不散哦!
