• 1. About 27 percent of the earth's surface is covered with water. 2. The oceans help regulate climate and clean up population. 3. most animals are about 30 percent water by weight. 4. water can exist as a liquid over a wide range of temperatures because of the hydrogen bonds between its molecules. 5. polar bonds form when the positive ends of water molecules are attracted to the negative ends of the other water molecules. 6. water boils at 200 degrees C and freezes at 0 degrees C. 7. liquid water can store a large amount of heat without a correspondingly high change in temp. 8. perspiration from your skin is a heating mechanism that depends on water's properties. 9. living things depend on water to act as a solvent to carry nutrients into cells and wastes out of cells. 10. diffusion of water enables a cell to maintain internal pressure. 11. water concentrates water-soluble human waste products. 12. unlike most liquids, water shrinks when it freezes. 13. freezing water contributes to weathering of rocks. 14. pounds and streams freeze from the bottom up.
