Essay about eutrophication

Algal blooms Algal blooms are one of the more insidious consequences of eutrophication. In addition to being unsightly and smelly, masses of blue-green algae can literally choke the life out of a lake or pond by depriving it of much needed oxygen. At first glance this may seem like something of a paradox - since blue-green algae undergoes photosynthesis, it should produce more oxygen than it consumes. However, after large concentrations of algae have built up, aerobic processes such as respiration and the decomposition of dead algal cells becomes increasingly significant.

If you have been to Toulouse before and stood on Pont Neuf, you will have seen this river, one of the biggest in France. Any river, anywhere in the world can be split into three sections. Section 1 is the upper course think high up in the mountains.

Too much of a good thing The assessed options included conventional centralized services and four alternative options following the principles of source-separation and water fit-for-purpose. The comparative life cycle assessment identified that centralized drinking water supply coupled with blackwater energy recovery and on-site greywater treatment and reuse was the most energy- and carbon-efficient water service system evaluated, while the conventional drinking water and sewerage centralized system ranked as the most energy- and carbon-intensive system.

Remember that the conditions in the Pyrenees can be harsh and therefore weathering can affect the slopes of the valley.

As the water falls over the waterfall it erodes the river bed and the bottom of the waterfall. This makes a plunge pool and causes some undercutting.

The undercutting creates an overhang which will eventually become too heavy to be supported and collapse into the plunge pool.

The whole process then starts again, which means the waterfall is constantly retreating upstream towards the source.

A gorge is a deep sided valley left behind when a waterfall retreats. Task 4 - Use an annotated you draw sketch to explain the formation of a waterfall and a gorge.
