Lakes, reservoirs slow water exchange, not communicating with the ocean. From the rivers of the lake characterized by the absence of the channel, from the sea — the lack of a direct connection with the ocean. Lakes are called inland waters sushi with stagnant or slowly flowing water.
Lakes regulate the flow of rivers, holding in its hollow basins of water and placing them in other periods. In the waters of the lakes occurring chemical and biological reactions. Some elements are transferred from water into bottom sediments, others Vice versa. In some lakes, mostly without drain, in connection with the evaporation of water increases the concentration of salts. The result is considerable variation in the salinity and salt composition of the lakes.
Due to the significant thermal inertia of large water mass of the lake softens the climate of adjacent areas, reducing the annual and seasonal variation of meteorological elements.
The shape, size and bottom topography of the lake basin change significantly with the accumulation of sediment. The overgrowing of lakes creates new landforms, flat or even convex. Lakes and especially Continue reading
