A lake or pond is a relatively still body of water. Its topmost layer called is the littoral zone, it is the layer that the sun can penetrate. This zone is usually from about 10 to 15 degrees C in the summer. This is the zone that contains the algae plants, fish, and snails, etc. The Littoral Zone is poor in nutrient and rich in oxygen by the end of the summer. Then there is a bottom layer- I'm not so sure what it's called. It sustains little life except for decomposers. This layer has no/little light. By the end of the summer this layer is poor in oxygen but rich in nutrients (all of the dead things from the top sink and decompose.) When fall comes around, the cooling results in a mixing of these layers and the lake freezes over, waiting for the cycle to start again in spring.
This is what I know of the physical features of lakes and ponds.
Geographical features are landforms or natural things. An example is a mountain or a lake.
Rivers, mountains, lakes, and natural heritage sites are considered as a geographical features.
