問問Master Joe
過去一個月來,報章雜誌都不斷報導關於地震和海嘯的消息,但報導上所講述的一些用語和原理大部分也令小朋友摸不著頭腦。何謂「斷層活動」呢?大家經常聽到的「黎克特制」究竟又是甚麼來的呢?地震又有何預測的方法呢?Master Joe 決定要為大家一一詳細解釋﹗ 科學家指地球板塊的位置與地震的分佈有著很重要的關係,因為位於板塊邊緣的地區會特別容易出現板塊移動,繼而引發地震,所以板塊邊緣地區亦稱為「地震帶」。那麼香港是否處於「地震帶」呢?處於非「地震帶」又是否代表不會發生地震呢?要了解這些問題,大家必定要先明白板塊移動的原理,就讓Master Joe的好友文老師透過實驗,模擬板塊移動,讓大家對地震和火山爆發的過程有更深入的認識吧﹗
