How are lakes made?


How are lakes made? Lakes may also be created by landslides or mudslides that send soil, rock, or mud sliding down hills and mountains. The debris piles up in natural dams that can block the flow of a stream, forming a lake. Dams that beavers build out of tree branches can plug up rivers or streams and make large ponds or marshes.


Why does the bottom of a lake not freeze?

Most lakes and ponds don't completely freeze because the ice (and eventually snow) on the surface acts to insulate the water below. Our winters aren't long or cold enough to completely freeze most local water bodies. This process of lakes turning over is crtically important to the life in the lake.
