Q:

What are preventive measures of noise pollution?

A:

Steps that can be taken to control noise pollution include erecting barriers to insulate noise producers, installing materials that absorb sound, dissipating noise-generating vibrations and placing physical breaks between a vibrating object and the hearer. Architectural acoustics use all of these techniques to protect residents from unwanted sound. In addition, roads and airports require special treatment to deaden noise pollution.

As eSchoolToday points out, tested methods for protecting neighborhoods from noise pollution include creating barriers by placing noisy machinery in soundproofed rooms or planting trees along roadways. Urban planning plays a key role in placing noisy industries, airports and major transportation hubs away from residential areas, as well as in regulating smaller sources of noise pollution such as public announcement systems, car horns and noisy vehicles.

Noise pollution from roads can be mitigated through careful design of the road, the materials used, better tire tread design and the erection of road barriers to limit road noise to the roadway itself. In addition, electric and hybrid cars help minimize road noise pollution.

The best ways to control noise pollution from airports focus on building airports away from residential districts, restricting flights to certain hours and redesigning flight paths. In addition, residential soundproofing can help control noise pollution for those living near an airport.

    How do you prevent factory pollution?

    A:

    According to environmental lawyer Diane Saxe, factories that wish to reduce emissions can practice either pollution prevention or pollution control. Pollution prevention means changing the way a factory operates so that it produces very little or none of a particular pollutant. This usually involves eliminating a certain chemical or material from its operations. Pollution control involves installing equipment that captures pollutants before they enter the environment.

    How does water pollution affect the environment?

    A:

    While water pollution has many impacts on the environment, its effects are most readily visible in the lakes and streams where pollution kills fish and other aquatic life. According to TEACH Great Lakes, biologists declared Lake Erie a dead lake in the 1960s, yet it was full of life. The problem was that it was the wrong kind of life, which caused a disruption in the lake due to pollution.

  • Q:

    What is the difference between heat and temperature?

    A:

    Heat measures the movement of molecules in an object, while temperature measures the average energy or heat generated by the molecules in an object. The faster the molecules move, the more heat they produce and the higher their temperatures become.
