Bogs will develop in former glaical lakes by the gradual accumulation of organic matter falling from beneath a floating mat of vegetation advancing out over the water.

fall from,后面接beneath,怎么理解?
fall from 意思是从……落下,beneath是下面,“从漂浮的植物垫下面落下”,感觉怪怪啊~

....
falling from (beneath a floating mat of vetation...)
okay?

沼泽在有机物质落下的逐渐积聚的前 glaical 湖将会从在水之上前进出的在植物的漂浮垫之下发展。
