Why is water important?

Water Water needed for life 80% of your body weight Personal hygiene Universal solvent Cooking Fire safety Shapes geology Grow plants 3 phases-solid, liquid, gas Climate Photosynthesis CO2 + H2O  CH2O + O2 Aquatic life Cooling agent Potable Filters UV rays

Properties of Water Hydrogen Bonding –High heat capacity –Universal solvent –Ice less dense than water Greenhouse Gas Clouds reflect light

Roles of the Water Cycle 1. Supply of Freshwater 2. Driving Force Behind Primary Production Primary Production Food Image courtesy of David Medcalf, Wikipedia Source: Wikipedia

Global mean Annual Air Temperature = 15° C!!! 3. Water Vapor Creates Climate for Life “Greenhouse Effect” Water Vapor – Absorbs Heat Lost From Earth’s Surface Without it, Surface Air Temperature would be 16° C Colder (36-66% of greenhouse warming due to water vapor) Life would not exist in most areas. Key Greenhouse Gases Water vapor Ozone Carbon dioxide Methane Nitrous oxide Chlorofluorocarbons (CFCs)
