What is the main benefit of ozone?
The ozone layer is a region of the atmosphere located between 15 and 30 kilometers above the earth's surface. Its main function is to provide a barrier to ultraviolet radiation by filtering out these rays from the sunlight, therefore, preventing that travel to the earth's surface, protecting the atmosphere.

How are nitrogen oxides are produced and their environmental impact?
Nitrogen oxides are produced in combustion processes, partly from nitrogen compounds in the fuel, but mostly by direct combination of atmospheric oxygen and nitrogen in flames. Nitrogen oxides are produced naturally by lightning, and also, to a small extent, by microbial processes in soils.
What do you understand by smog?
Smog is air pollution that reduces visibility. The term "smog" was first used in the early 1900s to describe a mix of smoke and fog. The smoke usually came from burning coal. Smog was common in industrial areas, and remains a familiar sight in cities today. Today, most of the smog we see is photochemical smog.
Where is the ozone good?
the stratosphere In the stratosphere, which extends from about 10 to 50 km above the Earth's surface, ozone is 'good' as it protects life on Earth from the sun's ultraviolet rays.
In what way is the existence of the ozone layer beneficial to living things?
The ozone layer acts as a shield for life on Earth. Ozone is good at trapping a type of radiation called ultraviolet radiation, or UV light, which can penetrate organisms' protective layers, like skin, damaging DNA molecules in plants and animals.
What is ozone air?
Ozone (O3) is a highly reactive gas composed of three oxygen atoms. It is both a natural and a man-made product that occurs in the Earth's upper atmosphere. (the stratosphere) and lower atmosphere (the troposphere). Depending on where it is in the atmosphere, ozone affects life on Earth in either good or bad ways.
What role does the Environmental Protection Agency EPA play in protecting the environment?
The Environmental Protection Agency (EPA) is a federal government agency, created by the Nixon Administration, to protect human health and the environment. The EPA creates and enforces environmental laws, inspects the environment, and provides technical support to minimize threats and support recovery planning.
What does the state Department of Natural Resources do to protect the environment?
The mission of the Environment and Natural Resources Division (ENRD) is to enforce the Nation's civil and criminal environmental laws, including the Clean Air Act, Clean Water Act, and hazardous waste laws.
What is the Environmental Protection Agency’s purpose for using risk assessment Brainly?
The Environmental Protection Agency's purpose for using risk assessment is to characterize the nature and magnitude of health risks to humans and ecological receptors from chemical contaminants and other stressors that may be present in the environment.

Which authority writes and publishes the multi modal hazardous materials regulations in the United States?
The Hazardous Materials Regulations (HMR) are issued by the U.S. Department of Transportation (USDOT) and govern the transportation of hazardous materials in interstate, intrastate, and foreign commerce.
Which federal regulations govern and control various aspects of hazardous waste management?
The RCRA of 1976 addresses the handling, disposal and recycling of debris and solid waste, including hazardous materials. The requirements of RCRA are implemented at the State and local levels and are often included as conditions or best management practices in permits required at those levels.
How does the vapor pressure of a liquid relate to its rate of evaporation?
Vapor pressure equals the rate of evaporation. a. The greater the vapor pressure, the faster the liquid will evaporate.
What is the approximate maximum capacity of a rail tank car in gallons?
Except as provided in this section, tank cars, built after November 30, 1970, or any existing tank cars that are converted, may not exceed 34,500 gallons (130,597 L) capacity or 263,000 pounds (119,295 kg) gross weight on rail.
How does nitrogen dioxide contribute to the creation of acid precipitation if it undergoes similar transformation steps as Sulphur dioxide?
Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.

Why is ozone beneficial in the stratosphere?
Stratospheric ozone is a naturally-occurring gas that filters the sun's ultraviolet (UV) radiation. This is typically regarded as 'good' ozone since it reduces the harmful effects of ultraviolet (UV-B) radiation. A diminished ozone layer allows more radiation to reach the Earth's surface.
