Aquatic Studies 2
Water Body Units, Waterbody Structures, Stratifcation of lakes
| Question | Answer |
|---|---|
| The epilimnion is usually well_____because of... | Well Mixed because its subject of most wind |
| Hypolimnion is much more____ because..... | More limited because of the deeper layers that isolate it from energy inputs |
| Thermal Stratification is known as what? | Layering that occurs in warm months within bodies of water |
| Epilimnion is what layer. Whats one Characteristic does it have. | top or 1st layer and its warmer,less dense. |
| Metaliminion is in what layer? whats one characteristics about it? | middle or 2nd layer and strong vertical differences in temp. |
| What are 3 major categories of characteristics of aquatic habitat? | Physical,Chemical,Biological |
| Limnology is the study of nature and various what compnets? | Physical,chemical,and biological coments of fresh water ecosystems. |
| Hypolimnion is what layer. Whats one Characteristic does it have. | third layer and its colder denser layer |
| As temp rises Chemical reaction____?Dissolved Solids______?Dissolved Gasses______? | Chemical reaction increasesDissolved solids increaseDissolved Gasses Decrease(warm water contains less dissolved oxygen then cold water |
| Dystrophic Lakes are what colour? and have what in them? | Yellow brown colour and have acid and suspended,colloidal,organic particles |
| What 3 colours that can be given? | Colourless,yellow/brown,blue/green |
| Turbidity is the opposite to what? | opposite to transparency |
| the more turbid the water less_______? | transparent |
| The unit of measurement for turbidity is? | NTU is the unit of meausrment |
| pH is the measurment of concentration of _____in a sample? | Hydrogen ions in a sample |
| pH hydrogen is meausreed in ? | moloes/litre |
| A change in one pH unite represents what? | represents a tenfold |
| True or false ph does not ahve any units? | true |
| Conductivity is normalized to temperature of 25 degrees C. to eliminate the change between temp. and conductivity. What would this be called? | its called EC25 |
| What are units for conductivity? | Microseimens/cm (uS/cm) or Micromhos/cm (umhos/cm) these units are equivalent |
| TDS(in mg/L or ppm)=0.67xEC25(in uS/cm or microhos/cm what is this? | a direct relationship between conductivity and(TDS) of a water sample so conductivity can be converted into TDS (in mg/L) |
| What is Biomass and what are the units? | is the weight of material in a lake expressed as a mass per unit area (g/meters squared) |
| Increases biomass per unit time. the units are g/meter squared/day what biological characteristic is this? | Productivity |
