Quick Answer: Why Thermal pollution causes the release of hot water by power plants is dangerous Mcq?

11. Why thermal pollution causing the release of hot water by power plants is dangerous? … This warm water decreases the solubility of oxygen and it changes the breeding cycles of various aquatic organisms.

Why thermal pollution causing the release of hot water by power plant is dangerous?

Explanation: One of the main effects of thermal pollution is they reduced the solubility of oxygen in water bodies. … Because power plants use water as a cooling agent for cooling down their machines. This used water is in high temperature and it is released back to the water bodies and cause thermal pollution.

How is hot water that is released from power plants harmful?

Power plants are the biggest sources of water pollution in the country. Power plant water discharges are filled with toxic pollution such as mercury, arsenic, lead, and selenium.

What is the danger of thermal water pollution?

The effects of thermal pollution include decrease the amount of dissolved oxygen in the water, which aquatic life requires, damage to larvae and eggs of fish in rivers, killing off some species of fish and macroinvertibrates that have a limited tolerance for temperature change, and migration of living entities from …

What type of pollution is caused by hot water from power plants?

A common cause of thermal pollution is the use of water as a coolant by power plants and industrial manufacturers. When water used as a coolant is returned to the natural environment at a higher temperature, the sudden change in temperature decreases oxygen supply and affects the ecosystem.

How is thermal pollution of water linked?

A common cause of thermal pollution is the use of water as a coolant by power plants and industrial manufacturers. … When water used as a coolant is returned to the natural environment at a higher temperature, the sudden change in temperature decreases oxygen supply and affects ecosystem composition.

What are 5 causes of thermal pollution?

What are five causes of thermal pollution?

What is thermal water pollution?

Simply put, thermal pollution comes from hot water or cold water being dumped into a body of water. … Thermal pollution is called that because it overwhelms the natural temperature control mechanisms that work in the water.

How do thermal power plants pollute air?

Thermal power plants are also one of the biggest contributors to the global nitrogen oxide levels. … Nitrogen oxides are known to present visibility and respiratory issues, and they can also combine with other atmospheric gases and moisture to form acid rain and smog. The other big pollutant to the atmosphere is ash.

Which of the following is mostly affected by thermal power plant pollutants?

6. Which of the following is mostly affected by thermal power plant pollutants? Explanation: The thermal power plant mostly causes air pollution by the emission of harmful flue gases.

What is heat pollution and what causes it and what are the dangers?

The heat that is released in the water has negative effects on all life in the receiving surface water. This is the kind of pollution that is commonly known as heat pollution or thermal pollution. The warmer water decreases the solubility of oxygen in the water and it also causes water organisms to breathe faster.

Which of the following is the most likely impact of thermal pollution from power plants on a river ecosystem?

Which of the following best describes how thermal pollution from power plants can affect aquatic ecosystems? Warm water discharged into rivers and streams decreases the oxygen content of the water, which reduces the number of fish species.

What are the main causes of thermal pollution?
