Document Summary

Tap water is probably more clean than water bottle. Take care of your health now cuz its a pain later. Interesting cuz if you freeze from bottom up, life wouldn"t be able to exist cuz it wouldn"t be able to freeze: surface tension: sticky ass nature of molecules caused by hydrogen bonds. Capillary action: slow-motion guys on youtube. Water (h2o: water has a dipolar molecule which means it has a mickey mouse head (positive h+ and negative o-2 ends which act like a magnet) Covalent bonding & polarity in water molecules. The hydrologic cycle: the circulation of earths water supply, processes involved. Transpiration- as water leaves plants as a gas. Storage in lakes and underground: *note that less than 1% of earths water is readily available to humans, basically, the water we have has been around a very long time and just gets reused. Sources of water: 97% oceans, 3% on land (2. 15% glaciers, 0. 62% groundwater)
