- How hot or cold the water is. Affects dissolved oxygen levels (cool has higher DO, warm has lower DO)
- The amount of dissolved solids in the water (TDS). Too much or quick changes in TDS levels can indicate problems such as decreasing clarity, bonding to metals in the water and increasing temperature.
- Acidic water. Caused by increased respiration (more CO2) and increased decomposition.
- Using measurements and numbers to describe something
- Organism that feeds on, and breaks down dead plants or animal matter
- Excess sand, soil, clay, or silt from flooding and erosion that creates poor quality
- Measures the warmth or coldness of a given substance. Recorded in degrees Fahrenheit and Celsius
- Measures the amount of dissolved oxygen in water
- A mountain range or a long area from which land drops steeply on one or two sides.
- Lake or body of water.
- Land consisting of marshes or swamps that can block runoff and floods.
- where loose sand or soil washes away when it rains
- a plant or animal that is introduced to an area that competes with native plans and animals for resources
- is the accumulation of sand and dirt that settles in the bottom of bodies of water
- the terrain of an area, like mountains, valleys, plains, and bodies of water,
- too many nutrients, mainly nitrogen and phosphorus, are added to bodies of water and can act like fertilizer, causing excessive growth of algae
- Excess sediment washed into river and streams that smothers the organisms that live on the bottom. The sediment blocks sunlight, which means that aquatic plants cannot grow (by photosynthesis).
