When a large mass of dirt and rock falls into a body of water very quickly the water is displaced and starts racing away from the slide.

当大量泥石掉入水体时，大片的水会迅速涌出。

I went outside and walked to a nearby playground where there were children playing on the slide, the swings and digging in the dirt.

我走到外面，来到附近的一个运动场边，小孩子正在那里玩滑梯、荡秋千、玩泥沙。
