[Select all that apply] Which of the following are problems associated with hydraulic fracturing?


Natural gas contaminating drinking water.


Earthquakes in areas not near plate boundaries


Placing of sand into the ground in a location where it was not originally placed.


The ability to extract natural gas and oil from smaller reservoirs.

Answers

The actual practice of hydraulic fracturing (or “fracking”) is only a small part of the overall process of drilling, completing, and producing an oil and gas well.

Environmental issues that are specifically related to hydraulic fracturing include:

water availability

spills of chemicals at the surface

impacts of sand mining for use in the hydraulic fracturing process

surface water quality degradation from waste fluid disposal

groundwater quality degradation

induced seismicity from the injection of waste fluids into deep disposal wells

Any kind of oil and gas drilling can additionally cause:

reduced air quality

noise

night sky light pollution

landscape changes such as forest fragmentation

disruption to wildlife corridors and habitats

It is important to note that not all of these potential impacts occur at every site and many impacts can be avoided or mitigated with the proper practices.

Imagine you heard the meteorologist on TV announce that the atmospheric pressure for the day is going to be 767 mmHg. You know that 1 atmosphere of pressure = 760 mmHg. So, based on the surface pressure map of the United States that you just created, which region (northern, southern, eastern, western, central) of the country might you be living in where the pressure is 767 mmHg?

Answers

Answer:

Southern

Explanation:

I think because that is closest to the sea level and as you go higher in terrain height pressure increases.

The region of the country the individual might be living in is the Southern part.

What is Pressure?

This is defined as the force per unit area of an object and is measured in mmHg or torr.

Increase in altitude leads to a corresponding increase in pressure which is why the individual was most likely closest to the sea level which is the  Southern region.

Write a thesis statement in response to the following prompt.Prompt: Read the letter to the editor "I, Too, Have a Dream." How does the writer use structure and language to persuade her readers and support her feelings about immigration?Dear Editor,I have never taken the time to write a letter to the editor, but something happened that lit a fire in me. Last week, as my best friend Areliss and I headed to class, a group of college protesters blocked our path. Their signs read "GO HOME" and "ILLEGALS LEAVE." They shouted, "Send them home!" These protesters couldn't have known what Areliss felt as they shouted and waved pamphlets in our faces like tattered flags. But, I know their words were bullets to Areliss's heart. I wanted to fire back to the protestors: Where are your ancestors from?Areliss came to the United States illegally, but she didn't do it intentionally. She was a baby. Her parents, seeking a better life, failed to follow the established immigration procedure, and they slipped into our country undetected. Once here, they raised Areliss, who would grow up never knowing any other home but America.Under DACA (Deferred Action for Childhood Arrivals), Areliss has been granted the temporary opportunity to remain here while she completes her college education. DACA ensures, at least for a while, that she will not be deported to a country she has never visited in her entire life.The term "DREAMers" refers to an act that would have protected these immigrant children if they attended college or served in the military. The DREAM Act did not pass, but its name has remained. DACA recipients have a dream: they dream that their lifelong contribution to the United States will one day be recognized, and they will be permitted to stay in the country they have always called home.Now, DACA is ending. Those who oppose DACA say it encourages illegal activity, weakens our borders, and goes against the Constitution. I understand their concerns. In an era of heightened security, we must do our utmost to keep this great nation safe. That includes establishing a healthy monitoring system for immigration.But, those who oppose DACA, who wield protest signs and who want to build walls, have never felt the dreaded doom of deportation. They forget that our long and colorful history has been built by many immigrantsincluding the immigrants who fought for and founded our country. They forget that Lady Liberty stands as a beacon, asking for the tired, the poor, and the huddled masses yearning to breathe free. We have a responsibility to them.To send DREAMers away is to deny that responsibility. Programs like DACA exist to keep the American dream alive.Yes, Areliss is a DREAMer. But I, too, have a dream. My dream is that DACA will be reinstated. My dream is that Areliss will be invited to stay in the country she has known as home since she was a baby and live out her dreams in the country she loves.Sincerely,Brittany Taylor Equation 1y = 5x + 32Equation 24y = 28x + 184First solve for X.
