Lakes and Ponds
What’s the difference between a lake and a pond? First, lakes are usually much deeper and wider than ponds. The water at the bottom is colder than the water at the top during the summer. In ponds, the water temperature near the top of the pond is about the same as the water temperature at the bottom of the pond. Plants grow prolifically in ponds. In lakes, they usually grow near the edges, but not in the middle.
Okay, now you know the difference between a pond and a lake. How do lakes and ponds develop? Lakes develop in many ways. As ancient glaciers slid down mountainsides, they sometimes caused huge piles of rocks to pile up. Lakes formed behind these rock piles as rain water collected. Volcanoes can also form lakes. Lava combining with cold water can cause huge explosions, leaving craters in the earth where a lake forms. Forest fires can also cause lakes. A marsh is a wet area filled with plants. As a forest fire rages through an area, it kills all the marsh plants, creating an open area for a lake.

Lake and Pond Q&A
Question: are lakes polluted?
Answer: Some lakes, especially those in mountain ranges, are quite clean. Others are very polluted. Pollution from fertilizers and soaps is a major problem. These fertilizers contain phosphates, which cause algae growth. When algae grow too much in lakes, they crowd out other plant life and animals.
