EAS 104 Oceanography Exam 2 Review Sheet Dr. Brenda Beitler Bowen Properties of seawater: What makes H 2 O unique? (ch.6) Earth is a “water planet” Water is the ONLY substance that occurs in all 3 phases (solid, liquid, gas) on Earth’s surface Able to dissolves substances more than any other common liquid (why?) Highest surface tension, heat conduction, heat capacity Polar molecule (H and O held together by covalent bonds) H-bonds holding water molecules to each other- cohesion, adhesion Heat vs temperature Heat capacity (why the sand gets hot, but the water stays nice and cool) Density characteristics of water as it goes through phase changes Latent vs sensible heat (energy used / released during phase changes) Effects of salinity on water characteristics Group 6- Desalinization of seawater: a viable fresh water source? Ocean chemistry: Why can’t we drink the seawater? (ch.7) Although 3/4 of the Earth’s surface is covered by water, 97% of this is salty! Water is a limited resource (that humans and other animals / plants NEED) Solution, solvent, solute, mixture Hydrologic cycle Major constituents in seawater (“Earth tea”) Chemical equilibrium Residence time Conservative vs nonconservative constituents
