This is the result of the Finnish climate, which is temperate and wet, and the characteristics of the Finnish bedrock and soil.</li>
<li>Most Finnish lakes are shallow and contain only a little water. </li>
<li><b>Lake and river systems </b>consist of lakes and the rivers that connect them. The waters of lake and river systems flow into the sea via a main river called an outlet.</li>
<li><b>Watersheds </b>are flat, boggy areas located in high elevations. They divide lake and river systems from each other. The primary watersheds of Finland are Maanselkä and Suomenselkä.</li>
<li><b>Groundwater </b>is water that is located under the Earth's surface. </li>
<li><b>Surface water </b>is fresh water that is located above the Earth's surface.</li>
<li>Waste waters and the nutrients contained in them cause lake <b>eutrophication</b>. This is why proper waste water treatment is important.</li>
<li>Key words: outlet, surface water, groundwater, eutrophication, lake and river system, watershed.</li>
