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.

The transformation of arable or habitable land into land that is dry and no longer suitable for agriculture is called __________.
A.
desertification
B.
deforestation
C.
extinction
D.
overgrazing
Answer:
Desertfication.
Explanation:
The activity that involves the process of producing plants and cattle is known as agriculture. Agriculture was a significant factor in the rise of sedentary human society, as it enabled humans to move to cities by producing surplus food from cultivated species.
A. desertification is the process of transforming arable or habitable land into dry, unsuitable soil for cultivation.
Desertification is referred to as the kind of drought land degradation in which organic production is killed as a result of biological cycles or human impacts, causing productive areas to become progressively arid.
It is the growth of desert areas as a result of a variety of factors, including climate change (especially present global warming) and human-caused soil depletion of resources.

State two importance of Rivers to the economic
development of Ghana.
Answer:
river is a large natural flow of water. On the other hand, a lake is a large area of water surrounded by land. In Ghana, there are different lakes and rivers of which all serve one purpose or the other. We have rivers like The Volta River, Bia, Tano, Ankobra and Pra, Ochi-Nawuka, Ochi Amissah, Ayensu, Densu and Tordzie rivers, etc. It must be emphasized that these water resources play a very significant role in the economy of the Ghana. So therefore, it is very needful for us to know what Ghana really gain from these rivers and how it continues in a long run to boost the Gross Domestic Product (GDP) of Ghana. Some of these of importance can be seen in the areas of the transportation of goods and passengers, Source of food and its aid in agricultural production through its irrigation abilities, Source of minerals, Source of employment, ability to boost the revenue of the government, generation of foreign exchange ear, and hydro-electric power generation. Firstly, the rivers and lakes in Ghana are a huge resource for food (which mostly comes in fishes) and facilitators of the agricultural sector also. About 8,000 tons of fishes are caught every year inland which helps decrease the import of fish for consumption. There are about 18 species of fish in the Densu including the Weija reservoir with Tilapia and mud fish being the most commonly fished species. The rivers and lakes inland are the major source of fish during closed fishing seasons at the coast. These fishes can also be exported outside the country which generates income for the nation and helps develop the economy. These water bodies also serves irrigation purposes to farmers and other agricultural producers. There will be no need for the usage of national resources to create irrigation dams when there are natural water bodies which can serve such a purpose. This helps in saving the country some money for other relevant projects. As these water bodies provide irrigation for agricultural producers, definitely it will increase crop yield and agricultural production even during dry seasons, and this will decrease the import of crops and other foodstuffs during these periods. And as it decreases imports, inflation will be checked and the currency will appreciate in value. Some basins of rivers like Pra contains most of the large cocoa growing areas in the Eastern, Ashanti and Central regions. Food cropping is more and more commercialized especially around the medium and large settlement and along the major river axes.

The graph shows a relationship between temperature and altitude in different layers of the atmosphere what information is true about the change in temperature
Answer: C.) varies in different layers depending on the amount of heat absorbed.
Explanation:
As shown by the graph, the temperatures in the different layers vary and this is due to the amount of temperature absorbed. The Troposphere absorbs heat from the surface of the planet which is why its closest areas to the ground have temperatures about 0°.
The stratosphere then gets warmer as a result of the Ozone absorbing the more harmful rays of the sun.
The Mesosphere does not absorb much rays and so is colder than the rest.
The Thermosphere is very hot on account of the sun's rays hitting it first thereby forcing it to absorb a huge amount of UV rays.

a rock takes off from earth an altitude of 1,140 km in 95 seconds.what was the rocket's average speed,in kilometers per second (km/s)
Answer:
the rocket average speed is 12 kilometers per second
Explanation:
Given that
The distance is 1140 km
And, the time is 95 seconds
We need to determine the average speed in kilometers per second (km/s)
So as we know that
Speed = distance ÷ time
= 1,140 km ÷ 95 seconds
= 12 kilometers per second
hence, the rocket average speed is 12 kilometers per second
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.

write about the he Earth's moon.(400 words)
Answer:
The Moon is Earth's only natural satellite. At about one-quarter the diameter of Earth (comparable to the width of Australia),[15] it is the largest natural satellite in the Solar System relative to the size of its planet,[f] the fifth largest satellite in the Solar System overall, and is larger than any dwarf planet. Orbiting Earth at an average distance of 384,400 km (238,900 mi),[16] or about 30 times Earth's diameter, its gravitational influence slightly lengthens Earth's day and is the main driver of Earth's tides. The Moon is classified as a planetary-mass object and a differentiated rocky body, and lacks any significant atmosphere, hydrosphere, or magnetic field. Its surface gravity is about one-sixth of Earth's (0.1654 g); Jupiter's moon Io is the only satellite in the Solar System known to have a higher surface gravity and density.The Moon's orbit around Earth has a sidereal period of 27.3 days. During each synodic period of 29.5 days, the amount of visible surface illuminated by the Sun varies from none up to 100%, resulting in lunar phases that form the basis for the months of a lunar calendar. The Moon is tidally locked to Earth, which means that the length of a full rotation of the Moon on its own axis causes its same side (the near side) to always face Earth, and the somewhat longer lunar day is the same as the synodic period. That said, 59% of the total lunar surface can be seen from Earth through shifts in perspective due to libration.[17]
The most widely accepted origin explanation posits that the Moon formed about 4.51 billion years ago, not long after Earth, out of the debris from a giant impact between the planet and a hypothesized Mars-sized body called Theia. It then receded to a wider orbit because of tidal interaction with the Earth. The near side of the Moon is marked by dark volcanic maria ("seas"), which fill the spaces between bright ancient crustal highlands and prominent impact craters. Most of the large impact basins and mare surfaces were in place by the end of the Imbrian period, some three billion years ago. The lunar surface is relatively non-reflective, with a reflectance just slightly brighter than that of worn asphalt. However, because it has a large angular diameter, the full moon is the brightest celestial object in the night sky. The Moon's apparent size is nearly the same as that of the Sun, allowing it to cover the Sun almost completely during a total solar eclipse.
