Because gases dissolved in water is different then solids dissolved in water, warm water holds less dissolved oxygen than cool or cold water
Hot water released in rivers or streams lowers the dissolved oxygen concentrations. Since fish also needs oxygen to live, they can't survive because there is not enough dissolved oxygen in the water for them to live off of.

The hypothesis that explains the release of energy during an earthquake is called the elastic rebound theory. According to this theory, stress builds up along a fault line until it exceeds the strength of the rocks, causing them to suddenly break and release accumulated energy in the form of seismic waves.

The O- Henry Playhouse - 1957 Hypothesis of Failure 1-30 was released on: USA: 1957
The hypothesis of an earthquake is that a sudden release of energy stored in Earth's crust causes seismic waves to propagate, resulting in ground shaking. This hypothesis is supported by observations of seismic activity, fault movements, and geological evidence.

The hypothesis regarding acids and alkaline substances states that acids release hydrogen ions (H+) in a solution, lowering its pH, while alkaline substances release hydroxide ions (OH-) in a solution, raising its pH. This hypothesis guides experiments to test the effects of different substances on the acidity or alkalinity of a solution.
