| A | B |
| run off | water moving across the land |
| crystalization | change from liquid or gas to solid |
| convection | heat moving in rolling currents |
| density | mass divided by volume |
| disolved oxygen | goes down in warmer water, state standard 6.0 ppm |
| turbidity | measures how much light penetrates water |
| three ways heat moves | conduction, convection, radiation |
| glaciers and ice caps | location of most of the Earth's fresh water |
| irrigation | man made precipitation |
| low levels of dissolved oxygen | Eutrophication |
| This is what there is most of in a solution | sovent |
| this is the stuff dissolved in a solvent | solutes |
| normal pH for water | around 7 |
| measures how acid or base a solution is | pH |
| Homogeneous mixture in which forces such a hydrogen bonding and ionization are involved | solution |
| atoms held together in covalent bond--electrons are shared | molecule |
| molecule or ionic crystal containing different kinds of atoms | compound |
| low pH | acid |
| high pH | Base |
| Not multicelular like plants, but lives in water and photosynthesizes | algae |
| Molecule with one end has a positive change and one end is negative | polar molecule |
| heterogeneous | unevenly mixed |
| homeogeneous | evenly mixed |
| adhesion | sticks to other stuff |
| cohesion | sticks to itslef |
