Lake, any relatively large body of slowly moving or standing water that occupies an inland basin of appreciable size. Lakes within the Atlantic National Parks (IBP < 0.1) are dominated by rooted aquatic plants and indicate senescence (excessive shallowness, high water color and high TP). Section 2.1, introducing the annual temperature stratification cycle, briefly repeats the formation of an epilimnion and the deep recirculation, Three Domain System . The basic terms used to describe these water bodies are defined. Low productive oligotrophic lakes are generally deep and clear with little aquatic plant growth. The above classification of the freshwater environments is based on two conditions: currents and the ratio of the depth to surface area. The water at increasing depth below the ice is progressively warmer and denser. e.g. In this kind of lakes, Evaporation < Precipitation.

This is the " period of spring circulation," or the " spring overturning." In healthy lakes there is a balance between sediments entering, circulating within the lake and being used to support aquatic life. Based on Danish lake data, we aimed to determine temporal variations, in particular natural year-to-year differences, and to describe the uncertainty in assessing the ecological state of lakes. Today’s Experiment Test the pH of Pepsi, tap water, and drain cleaner GOOD LUCK!!! Since lakes and ponds often contain currents or at least wave action and since streams often harbour quiet pools or calm backwaters, the difference between lotic and lentic waters is not very precise. Lakes typically reach this condition due to human activities, such as heavy use of fertilizers in the lake catchment area. Heather Hegi and Kerry Ritterbusch. A lake’s ability to support plant and animal life defines its level of productivity, or trophic state. Lakes with IBP = 0.2 are more permanent.
