Unit 5 Nature’s Temper Section A 2a-2d 课件2025-2026学年人教版英语八年级下册

海啸到底是如何形成的呢？其实它是由水下巨型能量引起的，通常火山爆发、海底滑坡或最常见的地球表面的板块滑动引起的海底地震。他们向水里释放出大量的能量，这些能量从下往上不断推动周围的水，使得这些水高于正常的海平面，但重力又把它们拉下来，撞击到正常的水面上，于是就使得能量不断向两边横向传播，这就是海啸的前身。由于受到海底源源不断的能量，海水横向流向海岸线，但当到达海岸浅水地带时，波浪就会受到潜水地带的反作用力，从而波浪高度就加剧升高，高度达到数10米，这就是真正的海啸。海啸是一种极具破坏力的波浪，不仅会淹死靠近海岸的人，还会把内陆1.5公里或更远距离的建筑物和树木冲平。如果你在靠海的地方游玩，请务必多留一个心眼，注意安全。 Excuse me, did you have any trouble during the typhoon?
