Human activities such as mining, pollution, minerals processing, landfills, etc have an effect on the flow pattern.
<h3>
Effect of pollution</h3>
It should be noted that pollution is usually difficult to control because it is often the result of human infrastructure around a river.
For example, sewage and effluent are discharged into rivers in some areas and this can lower the pH of the water, and hence affect the organisms.
Also, human activities such as mining, pollution, minerals processing, landfills, impact negatively on the quality of water and the flow pattern in the upper reaches of the blood river in Limpopo.

Answer:
- Reduced snow accumulations
- Earlier snowmelt in the Spring
- Spring flooding
- Less water in streams
- Reduced water availability
Explanation:
Less snow will fall in Winter due to the higher temperatures and, thus, will not accumulate. When there is less accumulated snow on the ground and the snowpack is thinner, then the snowmelt will occur earlier and faster in the Spring.
Quicker snowmelt in the Spring will result in rivers overflowing their banks because they cannot hold such a rapid influx of water. Rapid water cycle runoff will cause Spring flooding.
The snowpack will, therefore, be depleted early in the Spring season, and due to the earlier and faster snowmelt, there will be less water in the streams during the Summer.
The consequential lack of slow mountain snowmelt during the summer season will result in rivers flowing much less vigorously and with less volume over water. This means that downriver communities will face summer water shortages.
Metamorphic rock that is formed in deep in the faults is mylonite. It is a cataclastic metamorphic rock. Usually they are fine-grained, occasionally can be glassy, that are layered or streaky, with the layers and streaks being drawn by the ductile shear.
The answer is B. I believe that this is the answer because the barnacle is benefiting from the gray whale without harming, or affecting it in the process.
