3. ____________ comes under the chemical monitoring of the lake.
a) Detergents
b) Pathogens
c) Conductivity
d) Turbidity
View Answer

Answer: a
Explanation: The detergents comes under the chemical monitoring of the lake. Pathogens comes under the biological and the conductivity and turbidity comes under the physical monitoring of the lake.

4. Pollution enters into the water system in ___________ ways.
a) 1
b) 2
c) 3
d) 4
View Answer

Answer: d
Explanation: Pollution enters into the water system in four ways.

5. A large amount of soil can move with the run off called ___________
a) Soil erosion
b) Soil conservation
c) Soil pollution
d) Soil moving
View Answer

Answer: a
Explanation: A large amount of soil can move with the run off called as soil erosion. When the rain fall occurs, with the water, the top layer of the soil also moves.

12. Determination of flow increase is used for the monitoring of ___________
a) sea pollution
b) River pollution
c) Lake pollution
d) Tank pollution
View Answer

Answer: b
Explanation: Determination of the flow increase or stream treatment timing are used to monitor the river water pollution.

13. which of the following does not include in the monitoring of river pollution?
a) Assessing the immediate water quality
b) Development activities in the region
c) Determination of flow increase
d) Colour of the water
View Answer

Answer: d
Explanation: Colour of the water is the monitoring of the lake water and for monitoring the river water, we need to assess the quality of water, development activities must be done and water flow increase must be determined.
