How has the epa improved air quality over the last 30 years? a. by monitoring pollutants and passing regulations to reduce air pollution b. by decreasing soil erosion and dust storms c. by building marine refuges to protect marine life and reduce air pollution d. by decreasing of fossil fuel use in motor vehicles and industry

Answer

The EPA has improved air quality over the last 30 years by monitoring pollutants and passing regulations to reduce air pollution.

Explanation

The Environmental Protection Agency (EPA) is responsible for the functions such as issuing of environmental license, managing wastes, conducting research on the environment, enforcing laws on the environment, putting efforts that can reduce environmental risks and working with other nations to ensure to protect global environment.

Correct A). By monitoring pollutants and passing regulations to reduce air pollution

The Environmental Protection Agency is an agency of the United States whose main aim is to protect the human and environment health. It is the organization that improved the air quality by making laws and help in creating health of people and its environment. It was established in the year 1970 with the aim to protect environment.

Hence, the correct answer would be option A.

so here is the information for current research:

-nrel's geothermal analysts, scientists, and engineers perform a full range of research from developing advanced methods of locating and accessing geothermal resources to exploring innovative technologies to extract and produce clean energy from the heat of the earth

and here is the information for the technology of geothermal energy:

-it's clean and sustainable

-resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma

-almost everywhere, the shallow ground or upper 10 feet of the earth's surface maintains a nearly constant temperature between 50° and 60°f (10° and 16°c)

-geothermal heat pumps can tap into this resource to heat and cool buildings

-a geothermal heat pump system consists of a heat pump, an air delivery system (ductwork), and a heat exchanger-a system of pipes buried in the shallow ground near the building

-in the winter, the heat pump removes heat from the heat exchanger and pumps it into the indoor air delivery system

-in the summer, the process is reversed, and the heat pump moves heat from the indoor air into the heat exchanger

-the heat removed from the indoor air during the summer can also be used to provide a free source of hot water
