Which mineral mining practice is least likely to degrade the surface of the Earth?

Strip mining
Open-pit mining
Smelting
Heap leaching

Answers

Answer 1

Note that the mineral mining practice that is least likely to degrade the surface of the Earth is: "Open Pit Mining" (Option B)

What is Open Pit Mining?

Open-pit mining, also known as open-cast or open-cut mining and, in larger contexts, mega-mining, is a surface mining process that involves removing rock or minerals from the soil through an open-air pit, which is frequently referred to as a borrower.

Strip mining entails removing the top layer of soil and rock from a vast region to reach coal or other minerals underneath it. This process has the potential to substantially modify the Earth's surface, leaving vast, gaping holes that can be dangerous and ugly.

Smelting is the process of heating ore in order to remove metal from it. It does not entail any surface mining or excavation, and so has no direct impact on the Earth's surface. Heap leaching is a mining technique that involves sprinkling a leaching solution over a pile of ore in order to recover minerals. This method is usually utilized for low-grade ore and does not need any excavation or surface mining.

Excerpt from President Abraham Lincoln's Second Inaugural Address, 1865
If we shall suppose that American Slavery is one of those offences which, in the providence of God, must needs come, but which, having continued through His appointed time, He now wills to remove, and that He gives to both North and South, this terrible war, as the woe due to those by whom the offence came, shall we discern therein any departure from those divine attributes which the believers in a Living God always ascribe to Him? Fondly do we hope—fervently do we pray—that this mighty scourge of war may speedily pass away. Yet, if God wills that it continue, until all the wealth piled by the bond-man's two hundred and fifty years of unrequited toil shall be sunk, and until every drop of blood drawn with the lash, shall be paid by another drawn with the sword, as was said three thousand years ago, so still it must be said "the judgments of the Lord, are true and righteous altogether."

With malice toward none; with charity for all; with firmness in the right, as God gives us to see the right, let us strive on to finish the work we are in; to bind up the nation's wounds; to care for him who shall have borne the battle, and for his widow, and his orphan—to do all which may achieve and cherish a just, and a lasting peace, among ourselves, and with all nations.

Answers

The statement that best describes the role of nature in King Lear is option E. Nature works in both the background and foreground of the play to highlight how characters view the role of fate.

What part does nature play in King Lear?

The predominance of the bad characters in King Lear may give us the impression that nature is a terrible force. Edmund contends that nature is a wicked goddess who grants him the evil spirit required to question the existing quo. Thus, his badness is inevitable.

Since the dawn of time, mankind has made mistakes yet has continued. Since the original sin changed the way that human nature was created, mistakes, misunderstandings, and ignorance in general have become commonplace.

Therefore, Nature plays a significant role in the play's background and foreground, highlighting how characters perceive fate.
