Imagine that you are a natural resource manager at an underground mine. The mine is closing down because its
available minerals have been used up. You are now tasked with developing a plan to close the mine safely and
restore the natural area.
Name three steps your plan must include to successfully complete these tasks. Explain why each of these steps is
important to restoring the natural area,
Hey buddy! I think I can help u with this question!
closing mineMining operations, however expansive and complex, are temporary. Eventually, once the most accessible and valuable materials have been extracted, the mine is closed, and the site must be restored back to its original state. This includes covering up mine entrances, replanting grass and trees, and testing surrounding water, soil, and air for contaminants.
Since 1977 when the U.S. Congress enacted the Surface Mining Control and Reclamation Act, many regulations have been established to ensure mine sites are operated, and any environmental damage is remediated, in a responsible way. The Office of Surface Mining Reclamation and Enforcement (OSMRE), for example, is a bureau within the United States Department of the Interior created to address coal mine remediation.
The OSMRE’s mission statement asserts, “Our primary objectives are to ensure that coal mines are operated in a manner that protects citizens and the environment during mining and assures that the land is restored to beneficial use following mining, and to mitigate the effects of past mining by aggressively pursuing reclamation of abandoned coal mines.”
Some of the issues addressed by mine site remediation regulations include:
Acid mine drainage is one of the primary sources of mining-related pollution. Mining activities increase the volume and rate of exposure of sulfur-containing rocks to air and water, creating sulfuric acid and dissolved iron. This acid run-off dissolves heavy metals such as copper, lead and mercury which leach into ground water aquifers and surface water sources, harming humans and wildlife.
Tailings—mineral waste products—are another major pollutant. Because tailings originate in slurry form they are dumped in or near water, contaminating the water and destroying aquatic life. Tailings also can be transported by wind or water to contaminate other areas. Mine wastewater containing metals and chemicals can also leach into nearby waterways. Lab and portable technologies for water analysis can help determine the extent of the pollution.
In addition to physical landscape damage, mining operations create sediment containing heavy metals which settle into surrounding soil, or are carried by wind or water to contaminate rivers or other land areas. These metals aren’t biodegradable so the soil stays contaminated without corrective action.
Chemical analysis of soil and sediment samples at the mine site is an important step in detecting the presence of environmental contaminates that may remain as a result of mining activities. Both Energy dispersive x-ray fluorescence (EDXRF) and wavelength dispersive x-ray fluorescence (WDXRF) are good solutions for this analysis. Handheld XRF instruments provide instantaneous analysis in the field and effectively perform double-duty when used to monitor elemental contaminants at mine sites and in waste streams, in addition to being used for exploration and mining applications. These handheld analyzers are equipped with embedded GPS that can record the coordinates of the exact location of the contamination site as well. Lab-based WDXRF instruments perform accurate quantitative analysis of the vast variety of material, matrix types, and concentrations that must be evaluated in soil and sediment analysis.
Particulate matter (PM) in the air surrounding the mine location is another source of pollution. Dust results from the movement of soil, vehicles traveling over unpaved surfaces, heavy equipment operation, blasting, and wind, which can erode mine tailings piles to create potentially contaminated fugitive dust. Dust inhalation, particularly respirable coal dust, is a serious occupational hazard in the mining industry. Personal and ambient particulate monitoring equipment is used to measure PM to ensure exposure limits are not exceeded.
As it says in the Act, “Coal mining operations presently contribute significantly to the Nation’s energy requirements… and it is, therefore, essential to the national interest to insure the existence of an expanding and economically healthy underground coal mining industry…. [The] surface and underground coal mining operations affect interstate commerce, contribute to the economic well-being, security, and general welfare of the Nation and should be conducted in an environmentally sound manner….[And] the cooperative effort established by this Act is necessary to prevent or mitigate adverse environmental effects of present and future surface coal mining operations.” Read the rest of Section 101 of the Surface Mining Control and Reclamation Act of 1977.

calculate the percentage of PNG's urban population if the current population is 7,645 000 with an urban population of 977 000 people.
Answer: 12.8%
Explanation:
Urbanization rates show the the development of a nation because it shows how much of the population now live in cities which is synonymous with production and growth as opposed to rural areas which are associated with technological backwardness and agricultural overdependence.
The percentage of PNG's urban population can be calculated by the formula:
= Urban population / Total population * 100%
= 977,000 / 7,645,000 * 100%
= 12.8%
Describe coral reef ecosystem?
write in ur own words please
Answer:
A coral reef is a reef-shaped structure in the sea, formed by anemones and which over time becomes large enough to have a significant ecological and physical impact on its environment. These are the largest structures built from living organisms in the world. Coral reefs are complex marine ecosystems. They are a biotope (area of life) of a biocenosis (community of living beings) consisting of plants and animals, for example worms, shellfish, sponges, thorns and crustaceans. Coral reefs play a significant role as “breeding grounds” for the offspring of fish inhabiting the high seas.

Is it possible for a totalitarian government to exist under single-party rule?
O A. Yes. In order to maintain such a high level of control, there can be
no room for other political parties.
B. No. Totalitarian governments require absolute freedom of
industry.
C. Yes, as long as there is direct democracy.
D. No. A totalitarian government requires multiple parties to
participate.
Answer: A. Yes. In order to maintain such a high level of control, there can be no room for other political parties.
Explanation:
Most often than not, totalitarian states need to have only one party in the country in order to enforce their will without official opposition parties occupying positions in the nation's legislative and making it harder for the governing party to enforce its will.
And even if those parties do not occupy positions, they could be very vocal to the point of bringing attention to the ruling party's injustices. Restricting other political parties would therefore allow the ruling party to have total power without worrying about "meddlesome" opposition parties.

Answer:
average number of children women have is fertility rate.
number of births-number of deaths = death rate.
Average number of children women have in a lifetime? -> Fertility rate
Subtract total number of deaths and emigrants from total number of births and immigrants per 1,000 people? -> Population growth rate
Death rate -> The number of deaths per 1,000 individuals in a population per year.
What is population growth rate ?Population growth rate: The population growth rate is a measure of how much a population changes in size over time. It is calculated by subtracting the total number of deaths and emigrants from the total number of births and immigrants, and then dividing the result by the total population, and multiplying by 100 to express the result as a percentage.
A positive population growth rate indicates that the population is growing, while a negative growth rate indicates that the population is shrinking.
Death rate: The death rate is a measure of the number of deaths that occur in a population over a specific period of time, usually expressed as the number of deaths per 1,000 individuals in a population per year.
The death rate is an important demographic indicator that can help to understand population health, life expectancy, and other trends in a population. It is often used in combination with other demographic indicators, such as the birth rate and fertility rate, to analyze trends in population growth and age structure.
Fertility rate: Fertility rate refers to the average number of children that a woman has during her reproductive years (usually considered to be ages 15 to 49) in a given population.
The fertility rate is calculated by dividing the total number of live births in a year by the total number of women of reproductive age in that year, and multiplying the result by 1,000.
The fertility rate is an important demographic indicator that can help to understand population growth, age structure, and other trends in a population.
