<description>34. In two or three well-developed paragraphs, list four federal laws that relate to mining and reclaiming mined land, and state examples of provisions of each. 

Can I please get some help on this question? 

Thank you.

Environmental Science - y912f, Monday, March 15, 2010 at 2:54pm
. Mines on land in the US are regulated by federal and state laws. The Clean Water Act and the Safe Drinking Water Act, are two laws passed to ensure that contaminants from mines do not threaten water quality. The release of hazardous substances into the air, soil, and water by mining is regulated by the Comprehensive Response Compensation and Liability Act. Further more, all mining operations must also obey the Endangered Species Act, which ensures that mining activities will not affect threatened or endangered species and their habitats. 
Reclamation is the process of returning land to its original or better condition after mining is completed. A program was created by the SMCRA (Surface Mining Control and Reclamation Act) for the regulation of surface coal mining on public and private land. There are standards set by this act that would minimize the surface effects of coal mining on the environment. This act also established a fund that is administered by the federal government and is used to reclaim land and water resources that have been adversely affected by past coal-mining activities. 
There are also programs created by states to regulate mining on state and private lands. Mining companies must first obtain permits from state environmental agencies before mining a site. The permits specify certain standards for mine design and reclamation. Also, some states have bond forfeiture programs. In these, a mining company must post funds, called bonds, before a minign project begins. If the company does not mine and reclaim a site according to the standards required, the company must give these funds to the state. The funds are used to reclaim the site.

Explain what a coral reef is and how it is created. 

Coral reefs are limestone ridges built by tiny coral animals called coral polyps. Coral polyps secrete skeletons of limestone which slowly accumulate and form coral reefs. 

Discuss the locations where coral reefs are commonly found and why this environment is important to its growth and development. 
Corals live only in clear and warm salt water where there is enough light for photosynthesis, so coral reefs are found in shallow, tropical seas. 

List the different types of coral reefs and discuss what the different types of corals are. 
Describe some of the types of plants and animals that live in coral reefs. 
Thousands of species of plants and animals live in the cracks and crevices of coral reefs, which makes coral reefs among the most diverse ecosystems on Earth. Because of their convoluted shape, reefs provide habitats for a magnificent variety of tropical fish, and for snails, clams, and sponges. 

Explain five ways that coral reefs benefit human beings. 

Discuss three major threats to coral reefs. 
An estimated 27 percent of the coral reefs in the world are in danger of destruction from human activities. If the water surrounding a reef is too hot or too cold or if fresh water drains into the water surrounding a reef, the corals may die. If the water is too muddy, polluted, or too high in nutrients, the algae that live within the corals will either die or grow out of control. If the algae grows out of control, it may kill the corals. 
Oil spills, sewage, pesticides, and silt runoff have been linked to coral-reef destruction. Furthermore, over fishing can devastate fish populations and upset the balance of a reef&#x92;s ecosystem. Because coral reefs grow slowly, a reef may not be able to repair itself after chunks of coral are destroyed by careless divers, fisheries, shipwrecks, ships dropping anchor, or people breaking off pieces of it for decorative items or building materials. 

Discuss the issue of protecting and restoring these unique and valuable ecosystems. What are governments doing to protect coral reefs? What an you do to protect coral reefs? List any possible alternatives to create new coral reefs.

<description>I made a few more changes. Let&#x27;s hope everything is fine this time. Thank you. 

1) Mr Utterson decides to look for Mr.Hyde.  At last, Mr. Hyde appears. Utterson hears his steps approaching the end of the street. 
2) He is a small, plainly dressed man and his appearance shocks him.  When Hyde rounds the corner, Utterson steps up and, just as Hyde is inserting his key, Utterson touches him on the shoulder and asks, &#x22;Mr. Hyde, I think?&#x22;
3) Hyde shrinks back with a &#x22;hissing intake of breath&#x22;. He seems frightened but his fear is only momentary. 
4) He soon collects his cool veneer: &#x22;That is my name. What do you want?&#x22; Utterson introduces himself as an old friend of Henry Jekyll. 
5)  Hyde, keeping his head down, returns his greetings and then he coldly tells him that Jekyll is away. Utterson asks Hyde to show him his face, so that he will know him if he sees him again. 
6) The man hesitates for a moment before defiantly revealing his face. 7) The man gives Mr. Utterson his address in Soho and asks  how Mr. Utterson got his name. 
8) The lawyer suspects of the Hyde&#x92;s possible knowledge of Jekyll&#x92;s will. Then he replies that he got it from Dr. Jekyll.
9) Hyde accuses Mr. Utterson of lying and promptly disappears through the door. The lawyer is stunned by Hyde&#x27;s behavior. 
10) He believes Hyde&#x92;s personality is a sort of &#x94;murderous mixture of timidity and boldness.&#x22; Utterson realizes that until now he has never felt such loathing; the man seemed &#x22;hardly human.&#x22; 
11) Something disgusting characterized his body. He fears for the life of his old friend Dr. Jekyll because he feels sure that he has read &#x22;Satan&#x27;s signature on the face of Edward Hyde.&#x22;

<description>if a satellite were to be launched with too little speed or too much speed then what would happen?

If a sattellite were to be launched with too much speed then the friction in the air would make it heat up to the point where it would burn up. Earth&#x27;s gravity wouldn&#x27;t be strong enough to keep it in orbit, so it could escape. If a sattellite were to be launched with too little speed, then it would become to slow to orbit around earth. 

Any other information would be greatly appreciated, and please tell me if my looks correct, thank you in advance:-)</description>

<description>I need to write a explication about this poem, can you help?

A poem comes straight from inside the heart 
A poet with his own poem he will never part 
A poet feels and can see what others cannot see 
A poet can see beauty in bees and the fruitful pure tree 
A poet looks on and can hear words in his brain 
A poet can sometimes think he&#x92;s totally insane 
A poet feels happiness and sometimes he feels pain 
A poet is warm and feels so much love 
A poet is granted the poetry of love from above 
A poet is a poet and doesn&#x92;t he or she know it? 
A poet should let himself or herself quickly show it! 
Just write it on paper and let it flow.

<description>&#x27;We are currently in an energy crisis. After food, fossil fuels are humanity&#x27;s most important source of energy. These resources take millions of years to make. We are currently using the fuels that were made more than 300 million years ago, before the time of dinosaurs. Fossil fuels are a non-renewable resource; once they are gone, they are gone. Compose a research paper that investigates and reports on the biological and environmental aspects of this energy crisis.&#x27;

I need a link, or some help, to answer these questions about this topic:

-What biological impacts are we seeing as a result of the use of fossil fuels?

-What 3 solutions might you suggest to reduce our society&#x27;s dependence on fossil fuels?

-Discuss new innovations in technology that are currently being explored and implemented to help reduce our dependence on fossil fuels

-Review the pros and cons of alternative fuel sources.

Please help! Thanks

A card that is not a king and not a spade is drawn. 

I know there are 52 cards in a deck and there are 4 kings to a deck. And 13 spades in a deck.  So I added the two together which would make it 17/52= 33% is this correct?

<description> Two current carrying wires cross at right angles as indicated in the figure.

If the wires are not restrained, what statement best describes the motion of the wires?

Hint: To help you visualize the situation, draw first the magnetic field that Wire 1 makes at the points shown on Wire 2. Use those magnetic fields and the current of Wire 2 to find the forces on Wire 2. Repeat the same procedure for the magnetic field that Wire 2 makes at the points shown on Wire 1. Use this now to find the forces on Wire 2.

  
    Wire 1 moves out of the page; Wire 2 moves into the page  
   Wire 1 rotates clockwise; Wire 2 rotates counterclockwise
 
   Wire 1 rotates counterclockwise; Wire 2 rotates clockwise
 
   Wire 1 moves up; Wire 2 moves to the left  
   Wire 1 moves down; Wire 2 moves to the right

<description>Thank you for your suggestion. I just wanted to be sure that I paraphrased the following 4 sentences  correctly. I really hope you can have a look at them.

1) Mr Utterson heard his steps approaching (or getting closer?) as Mr Hyde was turning the end (getting to the end?) of the street. 
2) He was a small, plainly-dressed man and his appearance shocked him. Something revolting characterised his body. (&#x22;The look of him went somehow strongly against the watcher&#x92;s inclination&#x22;). 
3) Mr Hyde immediately backed away from him (as out of fear) with a &#x93;hissing intake of the breath&#x94; (how can I rephrase it? Taking a deep breath?) and then asked him how he got to know his name.
4) Mr Hyde hesitated but then &#x93;he fronted about with an air of defiance&#x94; (does it mean &#x93;he frowned defiantly?)</description>
