The correct answer is<span> a. release of contaminants
If you produce hydroelectric energy, you disrupt the water flow by building dams and power-plants, which also disrupts the aquatic wildlife that inhabits those areas. This also increases riverbed erosion because the water is accumulated and reaches further into the shore. </span>
When moist air flowing from the ocean meets a barrier
The answer is increased in urban growth because cities keep growing
The hardness of the water is given by the presence of calcium and magnesium <span>carbonates. The mixing of these minerals in water turns the water more alkaline.
</span><span>The Langelier saturation index uses the pH to predict the calcium carbonate stability of water. So, through the pH, it is possible to know whether a water is more or less acidic.</span>
Answer:
ponds cooler than 20 °C
Explanation:
There is great effect of temperature on the dissolved oxygen in a pond water,
When the water is hotter it will hold less oxygen but when the water is cold it will holds more oxygen. Therefore, ponds cooler than 20 °C will will have a higher average oxygen concentration.
