| River System | A river and all that streams that flow into it. The streams flow into a river called Tributaries. |
| Transboundary Pollution | Pollution that starts in one country and crosses boundaries into other countries. |
| Stage 1 - ¨Low Population Growth¨ | In this stage, High death rates, high death rates result in little population change. All populations began at this stage |
| Stage 2 - ¨Rapid Population Growth¨ | Birth rates remain high as the economic develops but the death rates fall as Food Supplies increase in healthcare improves. |
| Stage 3 - ¨Slow Population Growth¨ | As the economy improves the birth rates drop. Death rates stay low. Population growth begins to slow down. |
| Stage 4 - ¨No or Negative Population Growth¨ | In developed countries both birth rates and death rates drop to lower levels. As a result there is little or no population growth. Overtime birth rates may fall behind death rates. The result is a shrinking population. |
