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 is the reason that oil pollution attracts the greatest attention?
Explanation: Oil pollution of the sea normally attracts the greatest attention because of its visibility. They visible to the greater range because the pollution spread to the longer distance within a few hours.
What is an example of a point source?
Which of the following is the best indicator of SO2 pollution?
What is thermal pollution in environmental studies?
Thermal pollution is the degradation of water quality by any process that increases the ambient water temperature. The increase in temperature (a) decreases the dissolved oxygen/oxygen supply and (b) affects ecosystem composition.
What is the largest source of chronic heat pollution in streams and rivers?
Water as Cooling Agent in Power Manufacturing and Industrial plants:Production and Manufacturing plants are biggest source of thermal pollution. These plants draw water from nearby source to keep machines cool and then release back to the source with higher temperature.
What is the biggest cause of sediment pollution?
Construction activity is the most common source of sediment pollution. According to the Environmental Protection Agency sediment pollution causes approximately $16 billion in environmental damage annually.
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 are the major causes of noise pollution?
- Traffic noise.
- Air traffic noise.
- Construction sites.
- Catering and night life.
- Sleep and behavioural disorders.
What is thermal pollution give example?
Thermal pollution is the harmful release of heated liquid into a body of water or heat released into the air as a waste product of a business. An example of thermal pollution is water used for cooling in a power plant that runs into a nearby river and harms the river’s ecosystem.
What is thermal pollution in simple words?
Definition of thermal pollution
: the discharge of heated liquid (such as wastewater from a factory) into natural waters at a temperature harmful to the environment.
Which one of the following energy sources is most likely to lead to thermal pollution?
Coal produces more pollution than any other energy source. While coal produces just 44% of U.S. electricity it accounts for 80% of power plant carbon emissions. Burning coal leads to soot smog acid rain global warming and carbon emissions.
What are the effect of thermal 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 is most likely cause of the pollution in the river?
Sources of pollution
Farmers put fertilizers and pesticides on their crops so that they grow better. But these fertilizers and pesticides can be washed through the soil by rain to end up in rivers.
Which is responsible for the greatest exposure to carbon dioxide for living organisms?
Which is responsible for the greatest exposure to carbon dioxide for living organisms? Explanation: Cigarette smoking is responsible for the greatest exposure to carbon monoxide. Exposure to air containing even 0.001% of carbon monoxide for few hours can cause collapse coma and even death in the worst case.
Which of the following pollutants are responsible for the cause of smog?
2. Which of the following pollutants are responsible for the cause of SMOG? Answer: (c) Both incinerators and emissions from vehicles.
Which is the major photochemical smog?
What are the sources of the pollution?
- mobile sources – such as cars buses planes trucks and trains.
- stationary sources – such as power plants oil refineries industrial facilities and factories.
- area sources – such as agricultural areas cities and wood burning fireplaces.
What are some examples of nonpoint sources of air pollution?
Nonpoint source pollution can include: Excess fertilizers herbicides and insecticides from agricultural lands and residential areas. Oil grease and toxic chemicals from urban runoff and energy production. Sediment from improperly managed construction sites crop and forest lands and eroding streambanks.
What are point sources and nonpoint sources of pollution?
Pollution originating from a single identifiable source such as a discharge pipe from a factory or sewage plant is called point-source pollution. Pollution that does not originate from a single source or point is called nonpoint-source pollution.
Which is the best indicator of pollution?
Lichens are the best indicator of environmental pollution mainly SO2.
Which of the following is the best indicator of so pollution?
Which of the following cities has the highest SO2 pollution?
The worst performing city in the list is Singrauli in Madhya Pradesh with an SO2 concentration of 507 kilotonnes (kt) per year followed by Neyveli (393 kt) in Tamil Nadu Talcher (347 kt) and Jharsuguda (301 kt) in Odisha.
What are the thermal and nuclear pollutants?
What is E pollution and thermal pollution?
How does soil erosion cause thermal pollution?
Thermal pollution can as well be realized as a result of soil erosion. This is because continued soil erosion causes siltation and sedimentation thus raising the water levels which enlarges the surface area of the water exposed to sunlight. The more the exposure to sun’s heat the higher the water temperatures become.
Why is thermal pollution point source?
One of the key issues in thermal pollution is the replacement of cold-water fishes with warm-water fishes. Power plants and industrial factories are major point source contributors to thermal pollution. … This warming can ultimately result in increased fish kills associated with high temperatures (Caissie 2006).
What is thermal pollution long answer?
Thermal pollution is any deviation from the natural temperature in a habitat and can range from elevated temperatures associated with industrial cooling activities to discharges of cold water into streams below large impoundments. Page 4. SOURCES OF. THERMAL. POLLUTION.
What is a thermal shock *?
Thermal shock is a type of rapidly transient mechanical load. By definition it is a mechanical load caused by a rapid change of temperature of a certain point. It can be also extended to the case of a thermal gradient which makes different parts of an object expand by different amounts.
