What is a simple explanation for why water is densest at 4 degree Celsius?
How does this affect aquatic life in a lake or ocean during winter months?
During the winter, the surface water in a lake or ocean becomes colder and sinks to the bottom, displacing the warmer water below it. This creates a cycle of water movement and mixes nutrient and oxygen-rich water throughout the lake or ocean, providing a more stable environment for aquatic life to survive.
