Here's why:
* Solid (ice): Water freezes into ice at temperatures below 0°C (32°F). This is why we see ice in the Arctic, on mountains, and in our freezers.
* Liquid (water): Water is liquid between 0°C (32°F) and 100°C (212°F) under standard atmospheric pressure. This is the most familiar form of water we experience.
* Gaseous (water vapor): When water heats up above 100°C (212°F), it changes into a gas known as water vapor. This is why we have humidity in the air and why clouds form.
Water's ability to exist in all three states is crucial for life on Earth and plays a significant role in weather patterns and the water cycle.
