What impact do humans have on physical weathering?

Humans affect the rate of physical weathering in several ways. The first way I am going to discuss is acid rain. Humans have increased the rate of acid rain through our use of pollutants. Cars do a lot of damage because of their exhaust fumes. The sulfur dioxide and nitrogen oxide released from the tailpipes of cars go into the atmosphere and return back to Earth in the form of acid rain, snow, fog, or...

Humans affect the rate of physical weathering in several ways. The first way I am going to discuss is acid rain. Humans have increased the rate of acid rain through our use of pollutants. Cars do a lot of damage because of their exhaust fumes. The sulfur dioxide and nitrogen oxide released from the tailpipes of cars go into the atmosphere and return back to Earth in the form of acid rain, snow, fog, or dust. Factories throw away waste and release gases into the atmosphere. This affects the environment in a similar way cars do. Another way humans affect the rate of weathering is through the mass removal of vegetation. This is done when we are building highways, malls, subdivisions, and other structures. Deforestation exposes soil to high levels of rainfall and runoff, leaving areas open to wind and chemical weathering. Deforestation also exposes rocks that were once covered by vegetation. These rocks are now susceptible to all types of physical weathering, including acid rain weathering and biological weathering. Forest fires can cause the rocks that are located along the surface of the ground to weather as well.

What is hyperbole in the story "The Gift of the Magi" by O. Henry?

The most obvious use of hyperbole in "The Gift of the Magi" occurs when the narrator describes Della's and Jim's evaluations of their two treasures—her long, luxuriant hair and his gold watch. Had the Queen of Sheba lived in the flat across the airshaft, Della would have let her hair hang out the window some day to dry just to depreciate Her Majesty's jewels and gifts. Had King Solomon been the janitor, with all his...

How can I analyze Moon and Six Pence by Somerset Maugham?

In "Moon and Sixpence," loosely based on the life of Paul Gaugin, Maugham presents a study of the tension between the "civilized" life of 19th century Europe, and the lead character's desire to throw off the shackles of bourgeois life. Charles Strickland is a middle-aged English stockbroker with a wife and family. By abandoning his domestic life, Strickland commits what many in European society would consider a gross betrayal of one of the foundations of...

What are some literary devices in Macbeth, Act V, Scene 1?

Act V, Scene i of Macbeth certainly continues the imagery that is prevalent in the play with its phantasmagoric realm, as in this scene a succession of things are seen or imagined by Lady Macbeth. Imagery - The representation of sensory experience Lady Macbeth imagines that she sees bloody spots (visual imagery) on the stairs; she also smells blood (olfactory imagery): Here's the smell of the blood still. All the perfumes of Arabia will not...
