Map of Lakes in North America

Lakes are found all over the world on all of the continents. They are mainly found on the North American continent. In fact, 70 percent of all the lake water in the world is found in North America. One group of lakes in North America, the Great Lakes, contains 21 percent of the world's supply of fresh water. Only the polar ice caps contain more fresh water!

The temperature and precipitation of the lakes biome change with the 4 seasons, and they also depend a lot on where the lake is located in the world. During the summer, lakes in North America are usually about 4 degrees Celsius near the bottom of the lake, and 22 degrees Celsius at the surface. As time moves on, the fall brings a temperature of 4 degrees throughout the entire lake. Lakes during the winter are about 0 degrees Celsius, or freezing, near the top, and still 4 degrees Celsius at the bottom. However, even though the top of the lake is ice during the winter, the water which is underneath is still in liquid form. The higher temperatures of the spring melt the ice, and the temperature is similar to the fall temperature, at 4degrees Celsius throughout the entire lake. However, lakes' temperatures change, depending on where you are in the world. These temperatures are the temperatures for the lakes in North America, where most of the world's lakes are. The amount of precipitation also varies a lot throughout the world. For example, Lake Victoria in Africa has an average precipitation of 127.8 cm annually. The average temperature around Lake Victoria is 23.1 degrees Celsius. However, Lake Wood in Canada gets an average of 24.2 cm annually of precipitation. Around the lake, there is an average temperature of 7 degrees Celsius. As you can see, the climate of different lakes varies a lot. For this reason, there is no average precipitation for the lakes biome. Though all lakes biomes have many characteristics in common, the climate still has many variations.
