我刚读了这篇文章流星在大西洋上空爆炸州”由美国宇航局发布的数据表明,流星释放的能量相当于12000吨TNT(13000吨),它是移动超过每秒15.5公里(9.6英里每秒)。”Awesome. I understand that part. What I don't necessarily understand is how an explosion happened if the meteor is disintegrating. Is it when the meteor enters the atmosphere, or is there some reaction that I'm missing. Thanks!

PS -不明白溢出我应该将这个问题。这个听起来最好的。谢谢!
