Ice is less dense than water: Ice will float on water. Hydrogen bonds hold the ice in the ice shape. Important for marine life because ice only forms on the top.
High Specific Heat: The amount of energy to heat up 1 gram of a substance by 1 degree Celsius. It helps living things maintain homeostasis.
High heat of vaporization: The amount of heat to convert 1 gram of a substance into gas. This helps the earth maintain its temperature.
